Just to inform everyone, the underdrive pully that goes on the vette does work on our cars. It is a different belt but it does work. The car that has the pully on it, has a stereo and has no electircal drain whatsoever on this car. Chuck the owner of HPE, has this on his car, which should also add more power to our cars.

Good information, any idea how much gain?

I would have to ask, but he has more mods and think they were all done at the same time. So maybe I will have to find out more info from him

These are usually a 5-7hp deal. I looked into these before. If a pulley and a belt are involved this may be a little costlier than I first thought. What do serpentine belts run anyway $50, $75? Aren't the pullies around $100? I've certainly spent more for less power gain. :lildevil:

HPE put mine on last month. No problems over here.

Its not just a power improvement, the car also will rev up and down more quickly and respond more quickly because of the pullies. I put them on my 98 and 00 Trans Ams and loved that mod. I think I'm going to look into this. :)

Parker, did you notice a difference after the install?

I can't really say since I had it put on whenever they switched my smaller cam to the one that I have now. In my opinion every little bit helps, but I didn't do a before/after comparison.

HOW MUCH $$$ for the parts? and is it a DIY install?

Parker

It probably could be a DIY install, it was just convenient since they already had the balancer off, just decided to kill two birds with one stone. The pulleys are pretty high for the gain, probably around $300 or more.

So you used C5 Z06 underdrive pulleys. Am I correct?

Parker

It sounds like a mod for the NA cars. For us Maggified owners, it might not be recommended. I wonder what effects it might have on our boost with an underdrive pulley?

I'm in on the pulleys that's an easy one to do.
