Hey guys i have a couple questions about my truck.

The first is whey am i only building 27psi of boost? i have the fuel screw turned up, its at run away. the fuel pin has the deepest part forward. and no AFC spring. It also has the 21cm housing.

I have a 58mm S300, where can you buy bigger compressor wheels and housings for these?

Thanks

 

what are you running for a lift pump?? bigger turbo isnt going to make more boost if you dont have the fuel to burn!!

 

a holley black 140gph

 

stock fuel filter???
big lines??
why are you not running an afc spring??
does it smoke like the fires of hell when you stomp on it??

 

yes stock filter(for now).
stock lines.
wanted it to smoke back before i turned it up and never put it back in, but i probably will to see if it will make it run better at lower rpms.
it smokes pretty good until the turbo lights(about 15-18psi, i'm guessing about 2200-2500 rpms?)
