I am a newbe but it seems like a different intake and muffler will add about 5 to 6 hp from what Ive been reading. How many HP does it take to make a difference in a car like the fit? Will you feel the difference at that small increase or does it take a larger amount to really start to feel it?
thanks

well actually intake and exhaust you probably won't even gain that much you might even lose hp depending on what set up you go with and in the fit it really shouldn't take much to feel a difference since it is such low hp already but depends on where you are gaining the hp at lower or higher rpms.

people that put the kraftwerks superchargers say they are feeling a huge difference in their car and the base kit is only giving 30-40 hp.

 

personally this car is very sensative to power. I noticed very noticable gains from lighter wheels and a mishimoto carbon intake. nothing to hoot and holler about but noticable. but I think you would feel 10-15hp. but there are different ways to add power. nitrous is going to add fat tq which will feel like a lot more apposed to a supercharger or turbo. a centrifugal sc and turbo are going to pull hard towards redline.

 

actually, the kraftwerks supercharger for the a/t fits has a huge torque curve and it makes its peaks much sooner in the power band than one would expect.

havent seen to many turbo fit dyno sheets though.

most people with bolt ons go through the same thing:
their butt dyno feels power, but the dyno says otherwise.

i still say F.I. and a decent exhaust is the best route.

i've always felt that stock cars rated at least 20hp and/or around 15lbft-tq in similarly sized cars was enough to feel the difference.
