i can only guess. from the dyno sheets ive seen with JUST exhaust mods ive seen as much as 13 whp. add a bigger/ported manifold, cold air intake and a bigger throttle body i can see maybe another 10 whp if youre lucky. and a cam will add probably 20-30 hp depending if you get head work or not. a tune is suggested to get the best from these mods.
soo...here are some numbers.... stock dyno we put about 122 at the wheels, plus 13 whp for exhaust work if you do it right tahts 135, 10 for intake work, 145, and a cam which i havent seen a dyno sheet for but i see raw numbers so lets say 20 whp....165 to the wheels with those mods. of course you can go farther with more research and such.
