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

The first few 1/4 mile runs of my GT4088R powered aux bridge RX-7 project. The engine is a stock 6 port block, streetported with aux bridgeports, custom upper intake manifold, large front mount intercooler, Microtech LT8s, 720CC primary and 1600CC secondary injectors. Still tuning in the car and only running 13 PSI so these runs were not about trying to go fast. Just some test runs to get used to the car and see how it handles on the track. Note the seriously loud wail from the GT40, lack of traction in 1st and 2nd, and the high trap speeds. Lots of potential in this car once the boost is turned up and I've spent some time on the dyno...

"just an rsx" I resent that, i love my type s flavored rice. Still though, love this car after reading your rebuild walk through. Too bad the camera can't even do it justice.

Quote from hondaridinhot "ive seen 400hp on a streetported s5 t2 and a ported stock turbo."

Why are you saying an S5 T2 in this quote but now you're talking about a PP cosmo engine? pretty big difference.

[hondaridinhot]

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.

[aaroncake]

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.

[hondaridinhot]

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.
