Overdrive pulleys where can I get them?
I was advised to get some overdrive pulleys for my alternator, water pump and crank. Supposedly to help slow the revolutions of these items and to especially save my alternator, as I run the car at the drags frequently. Opinions? what size where do I get them, etc.
Thanks,
Steve

Obviously, since you are changing the diameter of the accessories you will need a shorter belt. How much shorter, IDK. You have to get the stock size and drop it down a bit and buy several, try them and return the rest.

Google "March Power & Amp under drive pulleys". Get the 3 piece aluminum set. Yes you will need a new belt. I think they help. When you buy them they will say what belt you need.

An hour ago I picked up my March 2-pc set from the local speed shop. The only difference in the 2 and 3 pc March sets is that the 3-pc set is "pretty" because the pulleys are aluminum finished and a water pump pulley is included, but it's the same size as stock.
I got the 2-pc set because it's half the price and does the same thing - and also because it's black so it's less likely to be noticed by the smog guys or whatever. The less the smog guys here see, the better.
March claims 13 hp at the wheels for the pulley swap. To feel that, you'd have to have a pretty well-calibrated butt dyno, but it sure can't hurt to have them on there.

Guess I should have said that I was repeating what the March guys told me when I called and asked about the differences.

I've had mine in a box for about 3 months now, haven't installed them yet because of fuel related problems, but there is no way they can hurt performance.

Do a web search on ASP underdrive pulleys.They underdrive the crank 22% and ALT. 15%. I was going to use them but found I had to switch to the newer one sided belt system[newer belt, tensioner,and power steering pulley].
