Custom Turbo I am having a custom turbo set up put together and the turbo I was recommended is a precision PT76(rated at 1150HP I believe). Is this a typicaly turbo people use? When the kit is put on we will run about 7-8 pounds of boost on a stock compression LS1. We may put heads on to lower the compression some, but assume we put this turbo on a stock ls1. What problems could you see running such a big turbo on this engine. Eventually we will put in an low compression 408 iron block and raise the boost a lot. Until then do you see any problem running 7-8 pounds on a stock ls1? I don't know to much about turbo's especially since this is going to be a custom build, I know more about superchargers, but it seems for a track/performance car turbo is the way to go. Any input is greatly appreciated. I started a thread at ls1gto.com, but the knowledge base is better. Thanks.
P.S.- I did plan to run a d-1sc on the stock motor and then upgrade the procharger to the f-1c when I got the 408, but it seems like the turbo is the better more upgradably route.
