Bolt-on power gains...?
I just ordered a few bolt-on items for my 370Z. They are the Stillen HFC, cat-back exhaust, Gen-2 Cold air intake. The other is the sway bar kit, but there's no HP gain in that ;-)
What I was wondering was what the WHP gains from adding these components would be? I am guessing in the range of 20WHP. Am I close?
