Controversy #1 – The CyberEVO team protests Sierra Sierra for potentially using nitrous.


Ian came over with a couple of scrutineers from CAMS (the Australian version of FIA) after Dave rocked the morning session with a blistering 1:29.024 lap. I was putting up banners to keep people and photographers out (more on this later) for the work we decided to perform. The conversation went something like this:

Ian: “Hey mate, is it an issue if CAMS takes a look for nitrous? The Japanese are suggesting that you might be using nitrous.”

Me: “Uh…..nitrous? You sure, dude?”

Ian: “Yeah……umm….I can’t really say which team, but you can probably guess. They are serious.”

Me:  “Wow they think we’re using nitrous? Mate, that’s a compliment. Maybe they aren’t accustomed to Cosworth power hahah.”

Ian: “It is a compliment, aye [some kind of Australian equivalent of between ‘huh’ and ‘eh’]? So is it alright if they have a look?”

Me: “Of course CAMS can have a look. Mike can show them whatever they want. In fact, we’re going to pull the head off right now so they can even look all around the inlet manifold for nozzles, holes, etc. The only thing I cannot show them is the deck of the block, but as you know, you can’t hide nitrous there. What the hell, why don’t you invite them over and have a look too?”

Ian: “Thanks mate. They think you are doing over 280 k’s [kilometers per hour] on the front straight.”

Me: “Actually Dave hit 298.89 kmh before slamming on the brakes. He was bitching about not hitting 301 k’s! ”

Imagine going into turn 1 at Eastern Creek with your speedo buried like this. Do drivers have a screw loose or what?


So while Mr. Takizawa, owner of the CyberEVO, may have protested us using nitrous, I don’t think anybody on the Sierra Sierra team ever took offense to it. He did come over and apologize after the event and personally apologized to me at the party at Darling Harbour the next day. I told him to give me a call if he needed an engine for next year (Sorry, Tomei). I have known Takizawa since 2005 and a little competitive protest wouldn’t be enough for me to dislike him. Competition is competition. Friends are friends. You can still be friends even in competition. I still remember the time Takizawa bailed me out in Phoenix back in 2005 when I burnt an ignition coil out on the XS Engineering EVO at PIR and will always be thankful for that. Unlimited Works, the shop that maintains the CyberEVO, were also concerned that we were offended or upset, but as you can see from the conversation between Ian and myself, that was not the case.

As I stated in my pre-WTAC article, Tarzan and the CyberEVO go fast with balance and response. Dave and the SSE EVO (Christine) lay down the lap times with brute power because Christine is a tank. Eastern Creek’s long front straight really just gave Christine the opportunity to stretch her legs (9000 rpm in 5th gear to be exact). The Cosworth engine and the BorgWarner EFR turbo is a truly wicked combination.


Carbon Fiber nitrous bottles aren't very heavy, but maybe next year I'll fill the roll cage instead. Smokey Yunick would have been proud of me.

The tube frame class might be a good idea...... it'll create a split which will: allow teams to make the choice to split off..... and it'll create a little incentive to back off from the ragged edge in the non-tube class to avoid building a car right out of class......

As any motorsport evolves, this will be the inevitable course of things, right?
Friday, August 12, 2011 2:50 AM
I was lucky enough to be at the event and was right there when you guys started to put up the banners around your pit area, with people peeping over and others trying to take photos over the banners. I was thinking, What the Fuck, is this China where people think it's their right to get other peoples hard work, ingenuity, creativity, for free. I stayed back out of respect and was wondering why others didn't.

I must say you guys would have won it if your stuff didn't break. Watching in the stands, it seemed SSE had a lot more to give than the 1:29.024 going around the track, were the Cyber Evo was on the edge for their 1:28.851. It was only a 0.173 difference which SSE could have made up.

I really hope to see you guys next year to take the title. Everyone on the race team was really cool and friendly. I wish you guys the best.
Friday, August 12, 2011 3:55 AM
great article eric, i wondered if there were any teams that stood out to you as having a ton of potential for next year. im sure with your critical eye you might see a team or two that had all the parts but needed to balance them to make them perform better.

Sounds to me like if Christine had been running on equivalent tires to those of the CyberEvo that it would have been no contest for SierraSierra to take 1st place and a good chunk off the CyberEvo's time too.

Sucks to hear about the gears getting chucked out of the transmission. Maybe it's time for Cosworth to design an awesome hi-po gearset :)

Big J - I'm not sold on the tube chassis split. For some teams, breaking records is their goal and tube chassis guys are going to have the advantage, which typically would force a shift TO the tube chassis to get those records.

Flyin_Z - Word! I was thinking the same thing. Who needs to up the boost to kill mode if you've got the same 'controversial' tire as your competitor?

ERIC - I love your honesty as usual and enjoyed your delicate show of distaste for 'certain' rule breakers this time. It does say a lot that the Cyberevo crew was man enough to apologize. I still think, though, in my heart of hearts that apples to apples (tires to tires) that the SSE is the fastest Evo in the world. Is Sierra Sierra more motivated to come back after this or are they still too close to it to even think that far ahead? It sounds like WTAC has your ticket booked already (Quantas of course) if Sierra Sierra doesn't :)

I think my only bummer is that none of those Australian (Ford and Holden) V8 supercars showed up this year!

Simon: it was good meeting you too. Sorry I couldn't share that Aussie beer with you. We worked pretty late some nights. Next year!

Big J: I think you are right. Either that or the organizers must be firmer on enforcing the rule book so that if a car is built out of class, its also out of the competition.

Jim: No bullshit, with the boost turned up and Emp getting comfortable with the track, I would honestly say there was another second in the car with little effort. There was probably even more in it.

willscarcast: another article coming next week that will discuss some of the other Pro class cars in more detail.

awdaltima: try calling sierra sierra

rawkus: the new floor worked well. we were able to dial out a lot of rear wing and still maintain stability. I think it was a big factor for our front straight speed.

Flyin_Z: i couldn't agree more regarding the tires, but oh well. Next year...

Kaane: Hollinger just released a sequential EVO gearbox. I think Albins, Drenth, and another company also have released sequentials. It hasn't been discussed yet, but it is what I'll be recommending.

Micah: 1000 horse Subies? They need to live at 800 first! Yes, plenty of drama in new forms of motorsports. Its the natural progression of any new sport I think.

Bruce: I couldn't agree with you more. In fact, I KNOW the SSE EVO is the fastest car in the world. Its just that the stars did not align. Last year we got our ass handed to us due to the CyberEVO team being ahead of the curve (and having been in time attack for 8 years before us). This year we had them at point blank. The damn bullet turned out the be a blank however. I think the V8 supercars were officially scared shitless last year. We'll see what happens though. I'm sure we'll be seeing some of them soon.

Friday, August 12, 2011 9:45 AM
Eric thanks so much for shedding some light about all this drama.
I'm glad you guys squared things off with other teams. It's never a good idea to burn bridges.
BUT !!! Rules are rules, and I get fucking pissed when people bend them.
I am a JDM whore at heart. Love everything Japanese but I can't stand it when the Japanese do this shady things because "they don't understand English very well"....that's BS.
Anyway, thanks again for sharing. Hope you continue working with SSE and support their program !

@Eric: Lots of the crazy powered Euro rallycross cars use Maktrak transmissions - AFAIK they have a bolt-on for the Evo. And with all the jumps, etc. those cars usually put much more stress on the drivetrain than the track machines. The crazy super & turbo twincharged + nitrous celica which set the fastest time at this year's Goodwood festival hill climb is also running an Evo drivetrain and Maktrak transmission. Here is their web site:

Regarding the tire durometer ratings, I've always wondered if it would be safe to use VHT compound on time attack tires to bring down the durometer a few points to have an advantage. Might be worth testing.

Here's hoping Christine's up to full kill mode next year. An extra 7 pounds of boost is a hell of a difference when the margin is under a quarter of a second. That said, if Christine's aero is a little behind the Cyber Evo, but you guys still had 40kph on them down the straights, you must have quite a bit of extra power. The gasketless head is interesting. Gas-filled stainless rings, or something even swankier?

The good news about all these controversies and potential cheating is that it proves how competitive WTAC is. Everyone's clawing for an advantage. You should hear some of the protests that come up in ALMS. Everything from BMW mechanics with bare ankles in the pits to Ferraris marking their stop box with illegal tape.

Saturday, August 13, 2011 7:10 PM
I've heard stories of Japanese teams doing things like you described-the tires are esp. sketchy. Reminds me of the FXMD's Yokohama slicks that were good for a lap and had to be sent back to Japan once they were used. But I suppose they have their "Unfair Advantage" and you have yours =D

A few questions: I've heard part of the reason why Japanese cars tend to be lighter than their American counterparts is the cages are designed primarily to stiffen the cars (on unibody cars) rather than to protect the drivers. Any truth to this?

In that same vein, why is Christine so much heavier than the Japanese cars? Going over your pre-WTAC post, she's running carbon body panels and is partial tube framed...OK, I can see how the Revolution FD could be lighter, but is she carrying that much more unibody than the Cyber Evo?

(Preface this with the fact that I'm no aerodynamicist) What's the future for aero? It seems to me like a underbody like that could benefit from having more air pumped thru it-maybe an upturn or "step" in the front splitter? I mean it's awesome that you guys fit a FA floor on an Evo, but from my understanding the aero on a formula car (esp the floor, rear diffuser and rear wing) are designed to work as a package. The floor and diffuser are a great starting point but I'm sure you guys could optimise the rear wing setup with some wind tunnel time. For the front, dive planes are band-aids. Throw a Rado style front wing on there! Just some random floating thoughts.

PS Where can I get some Sierra Sierra swag?? Gotta rep the fastest US TA team!

Saturday, August 13, 2011 11:25 PM
Eric can correct me on this, but most Japanese tuning shops don't emphasize so much on chassis stiffness. Many Japanese racecars (Time Attack cars) have very minimalistic rollcages (asides from the Revolution FD and the ASM Yokohama S2K).
Obviously with much less tubing the car is a lot lighter (a simple 8 point rollcage can weigh as much as 200lbs).

Christine is relatively heavy because of the complex rollcage (which was designed to stiffen up the chassis and protect Emp in case of a serious accident). Japanese people/ tuning shops don't pay much attention to that.

If you pay close attention to the Cyber EVO rollcage, it does have only a single side bar on the doors (IMO not enough to protect Tarzan from a severe crash).
Also the Cyber EVO does not have any X bars on the main loop, and no gussets on the A-Pillars. Sure the chassis is lighter, but it flexes a lot more that Christine's.
Like Eric stated early, Christine relies on gobs of power with a broad powerband, while the Cyber Evo gets away with a light chassis and good aero package (Voltex has been testing in the wind tunnel at the Mie University for years).

I believe Christine runs wet-carbon body panels, while the Cyber Evo has some dry carbon panels (dry carbon is lighter and stronger than wet carbon).

As far as the wind-tunnel question. Wind tunnels tests are cost-prohibitive. (at least here in the US). Im not sure if SSE has that kind of budget.
Der Bruce
Der Brucelink
Sunday, August 14, 2011 3:45 AM
A couple more things to build on what JDMized said, I read somewhere once that the Japanese like their minimalist cages because it saves on weight and they believe there is some grip to be had with some chassis flex. In fact, many of the cages are built to meet the minimal standards for time attack, not any sort of wheel to wheel racing.

With regard to the aerodynamics comments, there aren't many teams or even many manufacturers with wind tunnel access. I was researching aerodynamic parts like crazy once and found everybody has the ability to do the research and get/find out a ton about the aero on their car. The problem is that not too many people are willing to tape something like 4-inch long pieces of yarn ALL over their car. Maybe teams and/or magazines with unpaid interns might get gutsy and find where air flow rate problems are but most people make aero choices on theory or other peoples 'research'.

Sunday, August 14, 2011 5:19 AM
@Der Bruce, tufting a car and/or doing oil drops are a cheap, quick and easy way to get an idea of what's going on with your aero. You can find turbulent flow areas, find stall angles on spoilers, etc. They are actually techniques that we had used a few times in the windtunnel where I interned. It was usually for done for lower budget teams like Daytona Prototypes where they didn't have CFD and were making parts by best guess.
Sunday, August 14, 2011 5:33 AM
Why not hire someone who can run a CFD simulation of your aero package? No need to get a wind tunnel, simulation is much cheaper.
Sunday, August 14, 2011 9:56 AM
Great writeup Eric. It definitely answered a good amount of questions.

How did the Tibuc work out?

Drenth has a new R4 class sequential in the works but you might check out John McIntosh/Maktrak and their clean sheet sequential. He offers both a uprated bellhousing as well as a transfer case housing (it uses it's own main case). Steve Hill has been using it in D1 ERC competition with good success this season and the torque is most likely similar to the SSE car. John had previously worked at Hewland for 15 years and Xtrac before that.
Sunday, August 14, 2011 10:00 AM
I'd have to think the head sealing is probably pyramid ring with some rubber type moulded o-rings for coolant/oil passages. A few WRC designs have used that in the past and most of the big boost cars in scandanavia have been doing that for a while. Who knows though, Cosworth is usually at the forfront of engine technology so it could be anything.
Sunday, August 14, 2011 10:09 AM

Micah: The Subaru block has some fundamental issues way beyond just the liners walking around. It will be a long road to get around them. Prodrive tried some Wills rings several years before the end of the WRC days but from what I understand ended up with a different solution. That was all based on the EJ207 however. Good luck with that stuff. Somebody's gotta figure that out to elevate the Subaru platform to world class time attack status.

Michael Sheppard: Emp actually bought some VHT but totally forgot to bring it with him. We figured it was going to be worth a try. Maybe next time.

Ockham: The idea was not just to beat Tarzan's 1:28.85, but to smoke the crap out of it. Obviously that backfired and probably aggravated an already hurt gear I suspect. The cylinder seals are definitely swankier than gas filled stainless rings.

NBruno: JDMized got it exactly. If you read my pre-WTAC post carefully, I was messing around about the part where I said that Christine is tube framed. She actually has a very intact unibody. Too intact for her own good probably.

There's not a single time attack team in the world currently that has the budget for wind tunnel testing.

Unfortunately I don't think there's any SSE swag. So many people were asking, but I'm not sure why they didn't produce any. They could have sold it all at WTAC. Maybe next year.

Bruce: actually cages are not required at al in Japanese time attack cars. And yes, some of the builders believe that the chassis should have a certain amount of flex. That's definitely a strange one.

Kaane: Legit CFD simulation will require real world testing to validate and refine the initial simulation so that it correlates with real world results. I think a proper CFD sim program wouldn't be very cheap unless you had a dude cranking on it full time with access to a tunnel. Remember that any kind of simulation is crap in, crap out especially without any real world validation. You might be able to get a decent idea/rough approximation playing with a basic CFD package however. I think SolidWorks has spoiled the masses. Remember a simulation is not gospel. It is just that: a simulation. I would think the Voltex style big fan room might give you better results than a single stage CFD would.

Bill: I only got to try it in one session due to lack of time. My initial impression is that I suspect the valve isn't big enough for a turbo that size, but it could be that I just needed to tweak some parameters some more. I thought they were already pretty aggressive though. I'll give it another go if we ever test again.

The seals are not pyramid rings. The heads typically aren't reusable with pyramid rings. Unfortunately this is time attack and not GTP! There's not a budget for one time use cylinder heads unfortunately, but I can tell you that pyramid rings probably wouldn't suffice with a 4G63 head. It has other fundamental problems. The casting is shitastic at best.

How is that Drenth company? I've never heard of them, but I did check out a sequential Evo box before assembly when I was in China. The gears weren't REM'd, but they looked like they could benefit from it with all the little pits and dents in them out of the box.

Sunday, August 14, 2011 4:16 PM
hahaha yeah, the EJ definitely has it's issues. I like solving problems, so that might be part of why I like working with them so much. Like I said, getting to the 1000 point is going to be the issue. O-ring and using Wills rings has sufficed thus far.
I gotta say Eric, I'd like to sit down to a beer and shoot the shit with you. Making if things line up with an interview I have coming up in CA ;)
Sunday, August 14, 2011 9:24 PM
Hey Eric, just a thought: since Christine seems not to like too much boost, and since you've gone thru so many headgaskets and gasket-less attempts.....how about a cylinder head from Bullet (Australia)?

We talked about it a while ago. I know the cost is up there, but get a billet 4G63 head (since the casting of the 4G63 head is "shitastic" and analyze it at work, maybe?

Monday, August 15, 2011 7:09 PM
Wow. It sounds like the SSE and Cyber Evos are arriving at very similar times in very dissimilar ways. 40 km/h advantage on the straight? That must mean the Cyber Evo handles way, way better to make that up.

The Japanese chassis/aero guys should team up with the Cosworth engine guys ...

Monday, August 15, 2011 7:58 PM
Daewoo - If a car can carry a maximum momentum into a corner before breaking the tires loose, then the lighter car should be able to run at a higher velocity with the same momentum. p=mv. Don't forget that 40km/h is the max faster not sustained for very long at all. I'm pretty sure the CyberEvo doesn't handle "way, way better", even with its "over-the-counter" tires, with such a small margin of victory. "Pretty sure" and yes I just quoted myself!
Monday, August 15, 2011 11:38 PM
@Eric: I will look into that. I'll make some phone calls and see what people say about the billet head.

@DaewooOfDeath: It's very hard to say whether the Cyber Evo handles "way, way better", but what I can tell you is this:
The Unlimited Works/ Cyber Evo has a much wider track than Christine. Christine runs 295 width tires on the stock width body.
The Cyber Evo runs also 295 tires, but....
The Cyber Evo has flares in the rear plus extra additional flares OVER the existing flares. On top of that, the AME Tracer wheels they use have the lowest offset available, they poke out of those flares.
For the front, the Cyber Evo does also have wider fenders, like Christine, PLUS flares on top of the wide fenders. Christine runs wider fenders and that's it.

The Cyber Evo runs on double adjustable Tein Super Racing coilovers; excellent coilovers for the weekend warrior, not so much for a full-blown racecar, but they seem to do the job just fine.
Christine on the other hand rides on 4 way Dynamics coilovers from UK; much sophisticated dampening system.
The Cyber Evo weighs about 1040Kg. (2288 lbs.).
Christine weighs about 1250Kg. (2750 lbs.).
So, it's hard to say what cars handles better.

Another thing I'd like to point out is that many Japanese tuning shop like to keep stock sway bars and play around a lot with spring rate (many times very stiff spring rates) whereas many American tuning shop play around with swaybars AND spring rate, but generally don't end up with very stiff spring rates.

I enjoyed reading the writeup and its good to read things from behind the scene. But I would like to clarify one issue about the tyres, the 295 Advans were available to all WTAC competitors, even I received a bulletin about their availablilty and a cut off date to order them and I entered in the clubsprint class which doesnt allow semi-slicks. The CEO of WTAC has also mentioned the tyre issue here http://www.worldtimeattack.com/index.php/lets-clear-up-some-controversy

Tuesday, August 16, 2011 5:13 AM
@JDMsized: If you compare the Cyber Evo time from last year with say the Scorch S15 time from this year (roughly .87 second slower), you'll notice the big difference in the two is corning G's (though cornering speeds are very close), the big difference is how soon the Cyber Evo can accelerate out. In a straight line, the Scorch S15 is faster. So with that being said and noted, I think it's fair make the guess that Christine is either lacking cornering or off APEX acceleration (larglely a suspension/differential factor). Of course this speculation is based upon youtube videos with their shared data...I'm always suspect of data and their sources.

Anyone know if Cyber Evo ran a sequential shifter this year? They were an 'H' box last year.
Eric Hsu
Eric Hsulink
Tuesday, August 16, 2011 9:13 AM
RT: Fair enough. I don't really mind that the 295 Advans were available. What I mind is that the Cyber team brought their own tires off out of their container (I saw them unload their container while I was chatting with Tarzan) and that they measured a 46 on the durometer scale. If you or I went to the Yokohama truck and bought 295's A-050s, your tires would not have measured 46. They would not even have measured 51. They would have measured something more like 65. That's nearly 50% harder than CyberEVO's tires.

D of D, Bruce and JDM: Like JDM said the Cyber Evo weighs about 1040Kg. (2288 lbs.).
Christine weighs about 1250Kg. (2750 lbs.). Coupled with the CyberEVO's ultra wide track for a help in high speed stability plus the fact that it was on sticker tires, there's no doubt the CyberEVO handled "way, way better".

Micah: Sometimes it is funny to follow your passion as a hobby. Trust me on this one....

I'm figuring out some in car footage with Dave right now. He's got it all on his Go Pros.

Cyber is still running an H pattern, but they have a no lift shift strategy to improve shift time and quality.

Yeah, everyone once in while I really wish I had accepted HPD's offer...that last time I was flown out to CA. So is Cosworth looking to pick up any engineers? I'd much rather do design/test engine work in Torrance than in the bay area...or Maryland, like I do now.

I'm up in Hagerstown. I'm up here consulting for Volvo Powertrain's Performance and Emissions group. For the most part I sit in a test cell, make tests, crunch data, tweak things as needed and repeat...while I'm bored the other 80% of the time, well you can guess what I do to keep busy.

I am aware of the Japanese tuning philosophies. I'm using them right now, in fact, I'm going further than they do with spring to swaybar ratios. Already had several discussions on this matter. Suffice it to say I think that tuning philosophy might have had something to do with the CyberEvo's victory.

That said, I'm sure the Cyber Evo's much better weight, sticker tires and greater width helped as well.


As someone who gets destroyed on all straights by everyone every track day, I'm very familiar with being 25 mph slower down on the straights. I'm not familiar with Australian track layouts, but I'd guess that speed advantage combined with all the short straights Christine should have been winning as well, that the CyberEvo was making up at least a second on the corners and braking zones.

And anyway if not handling, where was the CyberEvo making up time? Christine's brakes are not abomination-level bad, are they?

Clearly a run of the mill Mazda here....

450 lbs less weight, stickier tires, and aproximately 2" greater track width can do wonders for entry and mid turn speeds. the cyberevo's ultra responsive engine also allows Tarzan to probably exit turns at a higher velocity too. With 12 turns and 3 of those being hairpins, I think that's where we got beat. This year the CyberEvo also stepped up to Audi R8 brakes too (production monoblocs) which gave it even more stopping power according to Tarzan.

Like I said, the only advantage we had was really power. There quite a few disadvantages the additional power had to overcome. And we were almost there...

Any plan for a diet? I can't believe the cage itself is 450lbs heavier. Any other places you guys can shave some weight?

Nobody said the cage itself was 450lbs heavier. Some differences I can think of right off the bat are in the dry vs. wet carbon parts on the cyberEVO and SSE EVO respectively. The CyberEVO also has a carbon roof where as the SSE EVO has a steel roof. There are for more, thicker, larger diameter tubes in the SSE cage. The SSE turbo and exhaust manifold are heavier. There is far less sheet metal cut out of the SSE car, etc.

There are places to shave weight, but the team decided not to cut weight out of the car in the interest of safety (and expense).

Are you guys looking into additional safe weight reduction? or just concentrate on power train development / reliability?

You're talking to the powertrain guy so I can only really comment on the powertrain. I can say that we are not further developing the engine at the moment. We have plenty of power and power band now.

Did the "bang bang" ever come into play??

Did you take much pleasure in saying: 280kmph??? ... nope, actually 298+ (lol)

Do any of the asian girls have the Aussi accent?!? I don't even like asian girls much and that sounds reeeeal nice.

I can't wait to see Christine unleashed without incident, in-freaking-sane... SSE owns TA at this point (not even a half a decade in, lol)

Are those stock axles EH?

eeeen: we tried the bang bang one session, but it wasn't working out. Due to more important stuff to sort out we really didn't get a chance to try dialing it in. The next time we test and aren't in such a rush I'll get to test it again.

Yes, it was cool to say that. It surprised the shit out of people. The radar reading on the front straight would never show up for Christine for some reason.

Yes, aussie asian chicks have aussie accents too. The ones born there have full on aussie accents. Quite nice...

Mxpop: no it has some heavy duty GKN rally/rallycross axles. After we snapped an American ""heavy duty" axle back in early 2010 we went straight to the buff stuff.

Eric, If SSE was going around the track two thirds as hard as the Cyber Evo you guys would have won. It's your destiny to take down the Cyber Evo. Third time's a charm.

I absolutely agree with # NBruno. There were so many people hovering around the SSE pit wanting to connect to the team that they could have easily sold a lot of "swag." I mean people go to an event and want something to remember how cool that day was with something physical, T-Shirt, jacket, button, sticker, key chain, patch, signature, etc. SSE could have made a killing.
Friday, August 19, 2011 8:51 AM
I've been bugging SSE to take my money for a sticker or shirt since 2008, back when they were running 1:45's during shakedown runs at BW13, lol... god I am pumped for SSE to get back to the States and hit BW13 with wick turned up!

GST, FXMD, WR... lots of teams who have been behind closed doors for the most part... (Mike, still waiting for the RLTA shirt I "won" for the GMp Cobalt question I answered, or does my SSE love negate my "win"???) :D
