What are your experiences with underdrive pulleys? on the new gt's, how hard are they to install? Noticeable difference?

i have then on my car, and had 1 of my techs install them for me. if you have a shop install them for you it should only take about 1 hour and should not be more than 100.00 at most. i dont notice a huge difference, but with everything i have. i like it.

I feel the car pulling more and I love it. Its the cheapest way to get an extra 10 to 15 horsepower.

+1 what my "tuner guy" said .. as far as 10 to 15 HP .. make sure you get a Steeda brand.. JMO on that.. how hard to due the job...??? look on EBAY ( people selling them ) will give you that info...
something about a powerful air ratchet.. (not a impact gun ) as there is no room with a impact gun...


best of luck...

UDP's add HP, but aren't going to help you at the track. Basically you're buying it to say I have 400HP instead of saying you have 390HP.
