I Was Wondering What Kind Of Horsepower And Torque Running On 91Octane With 18psi BOOST?

 

Way too open ended to answer.
Be specific with items like supporting mods and we can maybe guess,and that still doesn't mean somebody with 50 hp less wont spank you at the track if you cant hook it up.
Not trying to be mean, but hp and what you do with it is all relative.
My total shot in the dark at this very non-specific question isthat that combo has 400 hp potential, maybe more, but you have to have the right supporting mods.

 

it maxes out at around 400hp @ 27psi, and that's with race gas and full supporting mods. on pump gas and 18psi....figure 300ish maybe
