OK, I bought an Oxford White Cobra about a month ago with 50k miles on the clock. The only visible modifications that I can see are a CAI, Flowmasters and a smaller pulley. The belt was slipping when I got it and it was a 74.5 inch belt. I replaced it with a 74 inch belt (the 73.5 belt was too small). Based on the belt size and the fact that all of the other pulleys are stock I determined I have a 2.93 pulley.
Now here is where it gets confusing, I had the car dyno'd and it made 480 hp 473 tq with 14.6 lbs of boost. The blower is really loud too so I am thinking that my blower may be ported but there is not way to tell without pulling the blower. Do these numbers sound right or could the dyno be wrong? These numbers are not corrected but the dyno shop told me that because we are 30 ft above sea level and the temp was 75 degrees with no humidity that the numbers were correct. Dunno
