How Much Horsepower Should These Mods Net Me?
Hey guys! I just got off the phone with a performance shop locally that I'm going to be working with.
I'm getting the following mods done and I'm wondering if you guys could give a ball park of what to expect gains wise. Texas Speed 2' Long Tubes With X Pipe Texas Speed Cam Kit Roto Fab Big Gulp CAI 2.5' Pulley (to get stock levels of boost back here at altitude) 103MM Nick Williams Throttle Body Tune My goals for the car are really just a strong running street car which is why I'm just adding the smaller pulley to get stock boost numbers back. Not wanting to run 20+ pounds of boost lol. Basically just a really solid FBO car. Any guestimates on power from your guys experience? |

I thought 2.5 upper was stock size pulley? Also with the big gulp and 103 tb your bottleneck will be the supercharger inlet. Guessing maybe 660-680 to the wheels, possibly lower because of the altitude

Shouldn't the smaller pulley with normal boost levels put me back at just the regular stock 650hp by itself? the cam and everything else I thought would net me 150ish... I was thinking 700-750 wheel...can you help me understand better? |

I'm not missing any supporting mods am I? I told the guy at the shop that I wanted full bolt on plus cam and this is what he came back with. I'm assuming I'll have a very reliable street build? |
