RE: Underdrive pulley
ORIGINAL: anti92
I thought that a CAI was supposed to add like 5% HP, or free up 5% I suppose. Meaning that on a 132hp engine you should get around 20HP, but then again.. everyone tell's me that a CAI only add's 5 - 15 HP. So I dunno, just thought I'd add that info, I got the 5% thing from a performance part's site listed on DF.

If you want true numbers, buy the part, go to a dyno. Those numbers are not true.

in my opinion it doesn't add any horsepower at all (cai) but rather just frees up the power band a lil, smooths out acceleration a lil according to my butt dyno, but no REAL power increases.
