Yes, you should!
I believe Kevin was running ceramic ball bearing T4's with 60-1 compressors and a T3 hot side.

Glass is right. It's two ceramic BB T04E 60-1 compressors with T3 exhaust sides. The engine is a partial bridgeport using Ianetti seals with 4 850cc and 2 1200cc injectors run by a motec. With the exhaust housings I had on my last testing way back when before children and so forth there was almost no lag at all. It had an enormous amount of torque and pulled substantially harder than it ever had while running the 11.1 @125. Once dialed in I would expect in excess of 600hp at the flywheel on C16. I'm sure I'll finish it off this spring since I finally got my turbos back this last fall.

I found some old pictures of the turbos, not sure how they'll look since they're rather low res.




See if that worked.

Grrr can't seem to put more than one pic in the post. I'm pretty clueless with html

Kevin, hope you don't mind if I post a few pictures. Unfortunately, I don't have any showing your whole setup at once, so these close-ups will have to do...

Can't really see it too well but the large 3" tubes run under both headlights where a big K&N cone sits for each turbo. You can see the turn signal assemblies are out and the filters basically sit right there under the headlights getting fresh air.

Heh, kind of. That one was actually combining both into a single filter under the passenger side headlight. The one on mine had a tube going to a filter under each headlight. So the front turbo air source was under the drivers headlight and the rear turbo fed via the passenger side headlight. That picture is Kevin Tans car, kind of a prototype intake.

Yep, scans I made in '98 from Trev's 35mm prints. I have more pictures of the installation, including the additional injectors, turbo manifolds, and the welding jig if you want them.

Your crossover tube to the driver's side is shown in the first picture I posted, but that last picture was the only one I had of a tube going under the headlights. The fact that the car was blue, not black should have been the giveaway that it was Kevin Tan's car.

I would like to have any of the pictures you have scanned from Trev. Email them to me if you can.

Looks awsome, you have any idea what kind of power its making at the wheels on pump gas at say 17psi? I'm working on a 500rwhp pump gas setup and I was talking to a friend about going with something VERY similar to what you have.

Also, what is the eff range of the large IC? Will it take 1100 or so cfm? If so, you have any idea of the pressure drop at those cfm and boost levels?

BTW - guys, sorry I got off topic but since there were pics of everything I just got a little side tracked.
Thanks man,
STEPHEN
