I just had my 3.1 FFP underdrive pully installed today. What a difference it made. I love how the motor revs up faster. Even if it only gives 5whp, I can deffinitly feel the difference. The stock pully is huge compared to this one. It was worth the $120 I paid for it.
I still have to drive my car at night with the lights and stereo on, but I feel confident I won't loose any power. I've been running my basic stereo set-up [Pioneer deck, 6 Pioneer speakers, and a Pioneer 300watt amp] without any problems or power loss.
I look forward to installing mine in the near future.....have only herd good things about this pully.
Is the UD pully on these cars the same as the harmonic ballancer? if so i need to get one..

No, 3.1/2.8/3100 are internally balanced, so it just has a dampner on it.
where do you buy the underdrive pulley? do you need a smaller
belt? what is involved in replacing pulley?

Shane - give FFP a call.....Since they are 3 miles from my house the owner droppend off my parts on my doorstep (literally), you may be able to drive down to the Springs and pick yours up. I'm looking forward to your crossover & down pipe options...
