im want to buy a blower belt/pulley for a friend with a 2003 cobra. i would like to get 40 hp from it, but the stock tune still needs to be used. should a smaller belt be used? or a pulley? which is better? also how much, and where should i buy it?

Hmmmm..... Getting 40 extra horsepower from pulley is not a problem, but adding a pulley without getting it dyno tuned to ensure the A/F is still safe is DANGEROUS! I would take that chance...

thanks for the advice so far. is there any belt or pulley (okay less then 40 hp) that can up the boost without a new tune?

Depending on what the A/F ratio is in the cars CURRENT condition, you MAY be able to get away with a pulley swap down to a 3.10 in. I have heard owners say they were able to run a 3.10 without having to richen up the A/F. But why take that chance with a $10,000 motor? You're just playing with fire and the warranty that way.

I guess people are really drawn to the fact that a $75-$100 pulley can add so much HP/TQ to this car! It is a VERY good mod HP per $$ wise there's no debate on that...but do you really want to chance it?

Go buy your buddy a good CAI instead man. He'll get 15-20 HP/TQ gains from that and it'll increase the blower whine... best of all, IT'S SAFE!

which CIA do you guys suggest then? the densecharger? i have it on my bullitt and like it. I read an article in 5.0 mustang that it gave the best hp gain. Ive also seen the Jonny lightning one on a cobra. How is that cai, and how much does it cost? (where to buy)
