Hey guys, I'm running a forged 370 with a Turbonetics t76 and Trick hot parts. I have the standard 3 inch downpipe and I'm wondering if a 3.5 downpipe would help much. What do you guys think? If it will help, how much? Thanks

 

from what others have told me. yeah you will see a gain going from a 3 to a 3.5...

 

Creating a bigger pressure differential across the turbine is a very good thing. Go for it.

 

It definitely will not hurt to have more expansion immediately after the turbo.

 

Any guess on HP increase? Those DP are expensive.
