ST-series T4 turbo
I'd like my car (364ci) to be "efficient", in a sense that the power curve goes straight up until my desired red line. My T76gts (.96ar) would start choking at ~5800rpms at only 14-15psi of boost. My car is tuned by Rick at Synergy and he tunes it on the street. Then just for fun more than anything, I do a couple pulls at a local dyno-dynamics dyno. The owner of the shop says it reads ~16% lower than a dyno-jet reading.
Who knows. Aside from the ST-80, I am also switching to AFR heads and an AFR cam. 20 psi sounds like it would be fun!!!!
Pics of the new "freshening up" will begin to be posted Tuesday night!

I havent heard of very many....
I havent heard of very many....

Very cool, but not cost effective. Anyhow, I'm waiting for the new castings to arrive. If they don't pass our requirements I'm sending them back until they do. I won't have shXXy castings out there that can cause problems later for us. The prototype turbos that were made thoughare complete animals!!!

I have a 402 w/ a Turbonetics 76mm with a .96 exh housing. Problem is it is only pushing 15psi max and it isn't enough. It feels o.k. but I know it should be alot faster. Do I need to upgrade to a t6 flange or do you guys have a t4 to fit the bill?

I bet even with pushing 15 psi you have so much back pressure its not even funny and its sky rocketing your intake temps.......
Have you dynoed it at the current 15 psi level??
And then at 10 psi??? i bet there isnt a huge diff in power between those two.....
I would never put anything smaller then an 88mm turbo on anything over 400ci's.......
I was seeing back pressure issues with a GT42-76mm turbo (it has a T6 flange) with only 370ci's....
A T4 flanged 88 would help out alot, but up top your still going to have some flow/ back pressure issues...

It also might get slapped on before I go to the track on July 8th!!!!! Putting the 10pt and a bunch of other goodies on so I don't get DQed!
