Big thanks to Jonathan Perque of Bullet Motorsports for throwing this together. This is from the above mentioned rental that we attended a few weeks back. The second pass was the 8.05 @ 176 w/ a 1.31 60' thru a single 4' exhaustover the fender.

Here's another video from our last track rental of our local site. It was pretty hot out. I'm thinking 85ish*'s. Seeing what he can do on the Hoosier 275/60/15 drag radials.

I'm getting ready to wrap up this thread as this revision of the setup has pretty much come to a conclusion. Steve will be upgrading to v1.1 with smaller, more efficient turbos. I'll start a new thread to document results and give out the particulars. Big props to Josh @ KYTP for the killer deal on the new turbos and all the time that he spent with us and the turbo manufacturer on the phone to ensure that they would be a great fit for our expectations.

The current turbos are the TC78's with a 68mm exh wheel and .81 A/R housings. In that very last video, he had actually taken most of the exhaust off and it's dumped right by the transmission. The video before that had the 2 3" DPs into a magnaflow on each side and then merged into a single 4" going back over the rear axle and out the bumber.

New turbo spec info to be released in the new thread once the turbos arrive.Click the image to open in full size.

I'm pretty sure that he has -10 coming out of both pumps into a -12 Y. Then -12 to the Y in the back of the rails going down to -8 into each rail. Then -8's into the T to the regulator and -10 return to the tank.

He's using the Flex-a-lite twin slim S pusher fans. Seems to cool just fine. He does run an oil cooler as well which helps. The car gets really lite street duty. It never gets driven long distances in the heat of the day but he has had it out for some night cruises with a few hits and it only gets up to 215 ish and then comes down to 200ish IIRC. We are talking 30-50 miles of city and high way. The thing has a 3.2X gear in it though so it cruises at fairly low RPM even on the highway.
