Does anyone know the HP gains of a ported throttle body vs. the Vararam velocity stack? I have the velocity stack and was wondering whether or not I would see any gains. I'm thinking that I would because the stack fits inside and would seem to have less flow. Anyone made this comparison?

 

Don't think you will see anything with the velocity stack. The ported throttle body might give you around 5 HP. What I noticed was the car seemed to have better throttle response, crisper is probably a better description with the ported throttle body.
