I am thinking of getting underdrive pulleys.
Have those of you who got them found a difference in performance to justify the install?

Thanks

UDP's are said to be one of the better bolt-ons. Exhaust is #1. I put Steeda pulleys on and could tell a difference. Not huge, but for the dollars it's probably worth it.

UDPs were my last mod and I could definately tell a difference the first time I drove her after they were on. As for the belt, just get a new one. They're pretty cheap.

ORIGINAL: OV10stangI've got Steeda underdrives and I had a problem with my belt being noisy, annoyed the hell out of me. I went to the parts store and picked up a belt that was about .8" shorter, solved the problem.

In your sig you ran a 13.1 but trapped only 103. What's up with that? On 250WHP too, pretty good if that 13.1 is correct. Mark

Of course that's correct, that's why I posted it, lol. 2 main reasons for my et.... 4.10's and drag radials. I've seen others go quicker though, like Bill Putnam for instance. He broke into the 12's with similar power.
