World Time Attack Challenge 2012 - Competition Day 1World Time Attack Challenge 2012 - Competition Day 1

By Martin Gonzales


After one day of competition the 2012 World Time Attack Challenge is more than living up to all expectations.  Yes it's unfortunate Team America ended up on the wrong continent, but that has not slowed the fierce competition and there is still plenty to talk about.  Track records are continuously falling as teams in all classes have stepped their games up. 

The most talked about topics on track on the first day of competition were the strong showings put on by the Australian efforts.  The Nemo Racing and Tilton Interior teams clearly separated themselves from the rest of the Pro Class field by turning lap times faster than last's years winning time of 1:28.8510 set by Cyber Evo.  Yep, the Aussies were not here to mess around, but they weren't the only ones with plans for domination.  A total of 5 teams made the trek from Japan to compete and there was no way these guys made the trip to just show up.


Scorch Racing, World Time Attack, s15 
Just like we reported in our feature of the Scorch Racing's S15, the team showed up with a freshly completed rear aero package.  Would it be enough to overcome the Aussies?  We'll just have to wait and see.


A close look at Redbrick Racing's Evo IX engine bay.  Just look at the size of the piping feeding that Garrett GT35! (note: WTAC and Redbrick Racing websites say GT42, but in the picture is a GT35 compressor housing)  It looks like the exhaust manifold has some fancy ceramic coating too.        


world time attack, mazda rx8 
PanSpeed left the RX7 at home this year and brought out their new RX8 to Eastern Creek.  This was by far one of the loudest cars on track.  The BRAP-BRAPS clearly let everyone know who was coming around the corners!


world time attack, group a cars 
Though the stars of the show are the time attack competitors, I really got a kick of some of the old school cars on hand.  Not only were there some seriously clean examples on display, but they all did a few laps together during the mid-day break in the "Legends of the Turbo Era" session.  It was a really nostalgic site that any motorsports buff would appreciate.  If you don't know who Carlos Sainz is...look it up!

Good shit guys! Jealous for sure! And for the record we seem to have more info on the event than anyone else out there for a state based rag!

One engine for the event in Pro Class? 2010 the Cyber Evo changed its engine yes? this year Tilton brought 2 extra engines and i know that Redbrick Racing had 3 engines of various specs so that cant be right?

LeathanE = you're completely right. The "one engine" rule refers to only one engine can power the car, and that applies to all 3 classes.

Wes = Gracias compadre! We have some more good info coming your way on Monday.

Man, the Nemo Evo is fierce. I didn't realize that the whole side lifts up and the aero on the rear is incredible. Any chance at getting a close look at the car in the future?

Ok yeah that is true thanks for clearing that up then
Saturday, August 11, 2012 12:57 PM
Also Redbrick Racing uses a Garrett GT42 turbo not a GT35

@LeathanE, the WTAC website does say Redbrick is using a GT42, but that is clearly a GT35 compressor housing. So... unless they stuffed a GT42 compressor wheel into the GT35 compressor housing... Until further verification, I'm going to go with GT35 for now as that's what I can see.

Crazy times being tossed around. I am pumped to see U. Suzuki's time drop so low.

That is some insane progress for the Au. teams in just a few years... I hope the US and Japan have a strong rebuttal ASAP. I am counting on it.

No mention of AB aero was strange I thought?? hmmm.....

@eeeen - AMB Aero is evident on both NEMO and Scorch Racing S15. Andrew Brilliant was there at WTAC. supporting and helping at NEMO Racing coz he's also part of their team.

Just saying that as Redbrick Racing themselves say its a GT42 but i myself did think it looked abit small to be a GT42

@LeathaE lol... I think you misunderstand, again.

I am well aware of what he did, I was specifically referring to the lack of mention of AB aero, DURING THE INTERVIEW. If he handled all that aero for Nemo, AB's aero should have had some type of small mention in the "thanks", such a unique and important part of the car.

Whoops.... sorry LeathanE, I responded too quick, my fault. Wrong name.

@LeathanE, yeah, Redbricks own site says a GT42 (GT4294? GT4202?). But that is clearly a GT35 compressor housing. Now, it's quite possible that someone like Owens Development machined a GT35 compressor housing to fit a GT4294 compressor wheel. The GT42 compressor housing is TWO frame sizes bigger than a GT35.... so the compressor performance would definitely be compromised a bit.

You can go to turbobygarrett.com and look at the different turbos to see how the compressor housings look.

This is another picture of the Redbrick car:

To me, it looks like a GT35 center housing. Though, it's very difficult to make out and say with much certainty. I do not see a water line though... that's a no-no for long term reliability. Also, a GT42 uses a V-band connection from the center housing to the turbine housing. This picture clearly shows a bolted joint, standard GT30-35.

Nah, dont worry about it, Chris is always trying hard to mention everyone, there must have been a dozen interviews its all good. So many people worked super hard, trying to remember 20 names on the spot you know...

Are two cycle engines allowed? If your only trying to post a quickest lap and you can rebuild or swap the whole engine after each hot lap and emissions are of no concern AND the whole timed bit would be pretty much WOT, why would you want to use a power plant that is a comprimise in weight/power for added durability, low end torque and cleaner emissions right from the beginning?

@theneil: I don't think any of the teams are anywhere near the point of designging their own powerplants from scratch yet; doing so with the goal of actually bettering performance from heavily modified production based powerplants is nontrivial in terms of spending. I mean, you could raid the parts bins of old fully developed racing engines for far cheaper than that, and nobody has yet - think of what a Cosworth XD with no boost restrictions, or a Judd GV5.5 with no inlet restrictors (feel free to google either) could do - they'd most likely better any powerplant in use in WTAC in terms of power, weight, and probably reliability too, and they're customer engines that anyone can buy.
