underdrive pulley

[ZR1 MK]

What do you think of the underdrive pulleys for the LT5 offered by Specialized Racing Products?

While I have not used the product, I have seen them, and they are of very high quality. Very nice machine work and finish. :thumbsup:

Got them, have not installed them yet. Requires to much to be removed currently. Rather enjoy a full summer with a working car.

I don't see them adding much power for the headache that is involved. I haven't done it to my mustang (which is most peoples first mod) and I don't plan to on the ZR-1 either.

I have always had a reduction type pulley on all my previuos performance cars. When at the track, my engine typically runs between 3500-7200 rpm for 20 min at a time, so I figure I would be a better candidate than most. Still looking for feedback from others before I go ahead and order parts.
