Underneath the Skin of the Legendary CyberEVO
by Eric Hsu
As with the other times I've broken down cars in detail, most of what you'll read here are facts, but some of what you read here is speculation. In this particular case I've gathered facts and other information from speaking to Tarzan, the CyberEVO's driver, Ian, CEO of Superlap Australia, the guys at Haltech Australia (where Takizawa did some touch up tuning on their chassis dyno) and others close to the CyberEVO team. If you read something here and feel that you know better, feel free to pop what you've heard in the comments below. Just try not to sound like a know it all smartass because nobody likes a smartass. Jeff took hours to take these pictures and I'm taking hours to write about them so give us a break. Plus don't forget that MotoIQ isn't charging you jack so I hope nobody has a false sense of entitlement.
In general, the CyberEVO team is pretty hush hush and doesn't like to talk about their car in too much detail. In fact, I'm rather surprised they let Jeff take as many pictures as he did. I'm sure they were wondering why the hell this white dude was taking soooo many pictures. Being Japanese they were probably too polite to tell him to GTFO. Anyhow, Jeff did take over 600 images of the CyberEVO over three days time at WTAC 2011 between bottles of wine and beer. He was bitching that the hard stuff was too expensive in Australia (it is!).
A lot of changes are happening on the Cyber team with the most evident being that Voltex and Unlimited Works, the shop that builds and maintains the CyberEVO, will no longer be a part of the team. Depending on who you talk to there are different stories, but the one I've heard is that Takizawa-san's Sierra Sierra nitrous contest at WTAC 2011 was the straw that broke the camel's back. Up until then there were some disagreements and arguments, but contesting the nitrous sealed the deal. It caused a ripple that split the Cyber team up much like a rock band breaks up because personalities don't mesh and everybody might think they play an instrument better than the next guy. Whatever the case, I've heard that the Cyber team will return with the CyberEVO one last time for WTAC 2012 with Garage HRS replacing Unlimited Works and C-West replacing Voltex. If Garage HRS sounds familiar, that's because they used to build and maintain the CyberEVO before Unlimited Works did. Tarzan remains the driver and Takizawa remains the owner and engine tuner. Beyond 2012, keep your eyes open for the new CyberGT-R.
Whatever the future holds, let's take a look at the recent past. Jeff took these pictures at WTAC 2011 when Tarzan in the CyberEVO just barely beat Dave in the Sierra Sierra EVO by 0.389 seconds. While everybody, including myself on occasion, bitches that the CyberEVO isn't safe for the speeds that it's capable of, Takizawa-san took the concept of a Time Attack car to the max. It is a purpose built car that didn't cost a fortune to build and is extremely good at what it does. Sure, there has been CyberEVOs since the EVO 5 so it has taken a long time to get the current CyberEVO to where it is today. Everything is just good enough for one lap. Simplicity and weight are the keys to its success. Just like a band needs the right people to sound good and write a hit, the Cyber team in 2010 and 2011 had all the right partners to be the fastest Time Attack car in the world.
The CyberEVO uses some version of the A'PEXi Isamu RX-6 turbo upgrade with a an ultra lightweight IHI RX-6 turbo, thin wall stainless steel exhaust manifold, and an Apex water cooled 50mm wastegate. To give you an idea of how light they are, Honda used two of them on their F1 twin turbo V6 back in the mid 80's. I've worked with IHI RX-6s a lot and I think they weigh right around 11 lbs (5 kgs) a piece. For comparison, a Garrett GT35R weighs around 16 lbs and a motorsport grade Garrett TR30R weighs 12 lbs. There are four compressor wheels available in the RX-6 family ranging from 400-650hp, but surprisingly the CyberEVO's RX-6 isn't one of the larger compressors. Since IHI recently stopped production of the RX-6, I believe a guy by the name of Sagami in Japan now builds the CyberEVO's RX-6s.
The CyberEVO's transmission uses a stock casing, but is built with a 5 speed PPG straight cut dog gear set. For some reason, there are all kinds of racing gear set/box manufacturers and ECUs that come from Australia. I've used PPG gearsets in the past also. They make good stuff.
The CyberEVO uses a Tomei 2.2L engine with an EVO IX MIVEC cylinder head. The EVO IX head benefits from better combustion chamber cooling and of course the variable cam. Tarzan generally prefers response and a flat torque band over big, high revving horsepower so MIVEC suits his driving style with better low RPM power.

I really enjoyed reading this. They seem to only spend big money when they really need to, and for the rest just use what works.

Eric Hsu / WTAC articles are one of the best things about MotoIQ. Thanks so much, can't wait to hear more about the R32!

Seeing how much of the stock unibody is left, do Evo IX's have anything like the Subaru solid steel B-pillar hoop? Obviously, a full cage would always the way you'd want it done, but I've always wondered if Mitsubishi reinforced their stock bodies the same way as Subaru. Don't have a lot of knowledge of Evos (obviously) but it would make a little more sense for them to be relying on something like that than what basically amounts to separate c-pillar bracing. Not going to touch those door bars though, that's just straight up nuts.

That piece of aluminum with crushed bars is a piece only on the RS. On EvoM we've speculated that it's there for some sort of noise damping because obviously it's adding nothing to chassis stiffness.

Thanks. As an every man, I appreciate this article and appreciate even more what the CyberEVO team has accomplished with such a basic racecar.
That aside, i cant wait to see what extreme engineering Team America is going to dish out in the BNR32.

Interesting in a way; reminds me of the philosophy of a guy who raced in SCCA EProd - that after running whatever chassis for a good number of years, you end up with a really good idea what is and isn't essential to making the car go fast for you.
All this WTAC stuff makes me wish I had a sufficient bankroll to try some ideas I've had sitting. Or that some older cars (RCM Gobstopper for example) hadn't retired.

Nevermind, looked at the photos a little closer. Looking into the hollow B-pillars answered my question for me. Yikes.

Wow! It's really inspiring to see how fast you can go with ingenuity rather than cubic dollars. New favorite racecar here ...

"While ultra clean race cars are cool to check out, fast ones win."
That's a quote for the books. Looking forward to WTAC 2012.

The FPR looks like Sard to me. Is this article old?
Wednesday, March 28, 2012 3:53 PM
Hey Sourceinterlink, those aren't features, THIS is a feature! I'm kidding to an extent, I know they still help pay bills for you Eric. I just kind of wish WTAC had a certain required tire (no size issues, just specific tread wear and depth). Bragging rights and times mean more when apples are compared to apples! Thanks for the in-depth analysis and great pictures Jeff.
PS If I had an Evo and dollars, I'd have the paint wrapped with an aluminum/mirror finish and Japanese flag painted on the roof to fashion it after the old Mitsubishi A6M Zero. Kamakazi! Maybe Cyberevo should think about after seeing that cage!?

Daewoo: There isn't technically that much ingenuity in this car. It's all in the development of the combination of parts. If they were ingenious, they would have developed the car in two years. They've really taken about 10 if you include the original CyberEVO 5. I'm not taking anything away from the CE, but just clarifying.
Motary: the Sard FPRs are smaller in diameter and have that silly swiveling air fitting on top. I think that's a Tomei. The article is not old, but the pictures are from August 2011.
Bruce: I think the Japanese are ashamed of the Zero days. If they brought an EVO wrapped like that to Alabama, they'd get tarred and feathered or chased out of town by a posse.

Good read asside from that first paragraph.
That cage is a joke. Would fold up like a house of cards and leave the driver with a lot of fiberglass shards to contend with. Do engine mounting points have to be stock in WTAC? It looks like there is a lot of weight to be lost in the mount itself. it also looks like they are running a stock steel PS pump pulley
Wednesday, March 28, 2012 5:15 PM
Thanks for that reply Eric. Did you guys get any pictures of the front suspension too and can you please explain the need for that air duct for turbo, is it only for reducing under hood temps since the turbo is most significant heater?
That rear knuckle looks really nicely designed and machined

A true TA build, and it does seem tame compared to many other top level TA builds.
Great read with so many killer pictures. Still bumming that SSE "unofficially retired" their awesome evo, insane progress in a short time. Continuing to develop Christine further would have resulted in some crazy things.
Thanks for the post! Funny to think about a ZeroFighter themed TA car, probably not a good idea. I've always wondered what would happen if the wrong person saw someone driving an Evo6 ZeroFighter in 'Merica... lol
So the CyberEvo IS competing in the WTAC 2012?? Would be awesome.
I can't wait to see more on the ARK r32!

Freedom isn't free it cost a buck o five and so did that weld job! Looks like it took more time to write the article then finish those welds. Sadly, my welding is no better...

I had a full on hot lap ride as a passenger in this car with Tarzan driving in Phoenix Arizona at PIR. I have to say it was the greatest experience of my life, even after all the things ive seen and done living in japan. This car holds a very special place in my heart. The crew kept telling me before the ride "dont kick the ecu dont kick the ecu" The ecu and controllers werent hard mounted they were just hanging under the dash by the wiring harness'. haha Best experience of my life.

Eric, thanks for sharing. As always, you deliver!
Thursday, March 29, 2012 5:16 AM
Eric, not that it matters much.....but I've read (in my Japanese Mags), that the CyberEVO weighs 1080Kg. Hyper REV, Rev Speed, Carboy, Option/ Option 2, Motor Fan, all have written 1080kg.
Anyway, Top Fuel is coming back with their S2000/ turbo-full dry carbon car. And like you said, Yes, Nakajima is building a new aero for Hirano san.

Thanks for going in-depth on the CyberEVO.
For a car this fast, it is remarkably simple with a spartan interior. It also has what appears to be a modified DC5 Integra dashboard.

I'm quite disappointed to read about this car. The priorities seem totally out of whack to me, granted I may be wrong or just american in thinking but I can't help but wonder how much faster it could be if they spent the money they spent on CF and titanium on their engine (and safety equipment). I know Eric already said something about it but was it really necessary to weld aluminum to cool a turbo? There are lightweight flexible options that don't require cutting and welding or they could just suck it up and buy a better radiator and a water cooled turbo.
