| Re: The "4.9 liter turbocharger, stage 1" thread.
My point early on in this thread is with a high compression 4.9L, you DON'T want to make it efficient until high rpm. The high compression and boost will destroy weak pistons like 4.9's have. Be careful. I would recommend not hitting more than 2-3 psi until above 3500-4000 rpm.
Unless you drop the compression I don't feel you will ever have a good running 4.9 Turbo. |
