I have one my car....I actually have a obx pulley from a 4th gen on my 5.5....I had to cut the timing ring off tho....but u will need it...u shouldve posted in the 4th gen section...u prolly wouldve got more feed back homne skillet

 

I got myself a cosmoracing underdrive pulley and it works great, very cheap and good service. It has like 20% more throttle response, livelier 1st and second gear. from 2000 to 4000rpm, it wakes up the engine in city use. Very easy to install and dont forget to change the seal in the back.

 

Ok now does anyone have dyno graphs showing gains?
