Well the car had a POS Ebay turbo on it in this dyno as well lol. Wasnt a turbo from STS... Just had a STS based kit on it. We were also limited by the diablo programmer.. Not the finest tuning tool out there for the GMs ;)

Our same kit when i was at school at UTI in rancho we put down 550 with 6 psi, fast IM, SCT tuning

just an update on the car we have put on a new turbo it is running a hp 61 from agp a new intercooler bov and wastegate. but has not been back to the dyno but going to do vavle springs pushrods and upgrade the fuel system some more. but will post up the # after it is done and thanks for all the comments keep them come'n......Rich

Sounds really good.. I DON'T like that vacuum in your charge pipe when you punch it.. You need blow off valves.. Not only will it save the turbo bearings and reduce surge pressure on your TB and charge hoses, but if you hook it up right, you can have it linger open until your turbo spools up and it will increase your throttle response down low.. It sounds like a small improvement till you actually do it and wonder why you didn't do that a long time ago.. =)

just an update the car has been on 10 lbs for awhile now but has not been back on the dyno but going with a new turbo and clutch before it hit the streets this year so will try and get some new video s on soon...rich

5psi it made 424whp and 485ftlbs Looking to go back on 7psi :)

sounds like it was making some where in 450-500rwhp range it sounded nice and only 5 psi sts turbos are good man good bang for the buck whats the max they can push 15psi?

I got a chance to drive a GTO and I loved it and it wasn't even turbo...

intelligent, just dont talk lol. dont talk.

I love turbo domestics. Big torque, big top-end power. Big fun.
