Project Tina Quarter Mile Test Runs (Turbo Bridgeport RX-7)

8,000 RPM.

400HP could never happen on a stock turbo unless it is a hybrid. And in that case, it's no longer a stock turbo. My car dyno'ed at 320 RWHP @ 13 PSI with no tuning. An hour on the dyno and it put down 392RWHP on the same boost level. I've done a little tuning since then and at the same 13 PSI, it put down ~420 RWHP. Just last weekend I turned the boost to 16 PSI which should be damn near 500RWHP.

it was the stock turbo. it had been ported and clipped quite heavily but it was still the stock blades and housings. it helps that he was using meth injections and a peripheral ported cosmo engine. but like i said either way you still have a very nice car that deserves alot of respect. it takes somebody with alot of time and dedication to fab a setup like yours and you did an amazing job on yours.

I appreciate the comments, but I will still have to contest making 400HP on the stock turbo. It simply is not possible with stock wheels and housings, no matter how much you port the housings or clip the turbine. The compressor is not able to flow enough air. The compressor map is widely available, check for yourself. Running that turbo on a PP engine would make the problem worse, not better since the turbine side would be a cork in the exhaust. It must have been a hybrid turbo of some type.

ill ask him later on today to make sure but i was told it was the stock turbo. it might of been some sort of hybrid but to my knowledge it was the stock housings and stock wheels.

Around 107-109 MPH on average. The car is running a GT4088R currently at 13 PSI. At the time the video was taken it was tuned very rough in boost and made 320 RWHP. After the video was taken I spent some time on the dyno tuning and made 392 RWHP at the same boost. I've done a little more tuning since then and am currently just over 400 RWHP (need to dyno again). This car currently has an open diff which makes good 1/4 mile runs a challenge. LSD coming soon as soon as I get around to installing.
