lets play a game, where do you see full boost with your ebay t72 or t76? So I'm looking at using a ebay t72 or t76 on my stock lq4, and I'm wondering where you guys reach full boost? Tried searching but got lots of garbled answers. So....... answer these simple questions......
1. What motor are you using
2. Stock or modified? (short answer please don't need 2 know your whole build)
3. What t72 or t76 are you using and what's the ar on the exhaust?
4. Where does it start making boost @ and where does it make full boost and at what rpm?
For example
1. Lq4
2. Upgraded springs, stock lq4 cam, truck intake, truck exhaust manifolds, and no exhaust
3. On3 t76 .96 ar
4. Starts making boost @ XXXXrpms and my max boost is XXpsi @ XXXXrpms.
I'm stuck because I wanted to use a t72 because the compressor map is almost the same as a t76 but it only falls off a couple hundred rpms sooner but comes in about 800 rpms sooner. The ebay t72 has a much larger exhaust wheel than the ebay t76. My goal is to make boost down low and have a motor that makes fast low end tq.
