Pulley setup for race car?
I'm building an 84 C4 road race car... I'm eliminating the ac compressor and the air pump. Looking for ways to to set up the pulley/belt arrangement to drive the water pump,alt. and power steering pump, Can it be done with the stock locations and brackets? Is there a good aftermarket setup? Will use an underdrive crank pulley. Must use stock type belt(rules).
Thanks for your help,

Can you run dual serpentine or stuck with a single?
You can get something like this through CV products all kinds of neat setups. This setup was not cheap.
Beware of the look alike stuff (esp PS pumps) through the speed shops/ebay. They look the part but fly into little pieces at higher rpms.
If its gotta use stock stock stuff TPIS and a few other guys have some good setups with acc. eliminators.
F body setups have some options too that should fit on yours.
3rd gen..some midmount options using factory parts.

This is an expensive way to do it but I wanted a reliable system and I wanted the extra weight of the Alt. moved....
And this is the way I ran it before...a much cheaper option.

Thanks everybody...Nice looking stuff...
Right now,the cheaper version is appealing. I assume the rod ends are doing the tensioning...I can't see how the PS pump and lower alt. are mounted.Stock brackets? Right now,the engine is out to the engine builder so I have no frame of reference...Is an underdrive alt. pulley neccessary in conjunction with the underdrive crank pulley? Belt #'s?
I like the Tstat housing.
I'm looking for a triY(4-2-1)header...Does anyone know who makes one for a C4?
Thanks,Bagman

For least expensive, a shorter belt should be $15ish.
Be careful of under driving everything, it will affect cooling ability.
I do have a standard rotation pump for sale but the impeller is stock like and wouldn't be the best choice for racing.
I just reused the A/C brace on the alternator for mine. I made a thread about it if you search my threads.

I have mine setup like the second picture in Matt's post. I thought I had a picture but I guess not.... The best I can do it the way the alt is mounted (I think I was taking a picture of something else)

Thanks Aardwolf and everybody...I've got it. All of the pictures showed some very nice preparation!! There are a number of track related questions(setup,tire choice etc.) that I'd like to ask as I get closer to the car being ready.

Anytime! Love to talk cars! I've had it in the back of my mind to move the alternator to the passenger side like Matt did. I'm still using the stock brackets etc. Every year I'm amazed that stock PS system lives. Alternator too, it's really spinning to fast at the increased RPM of this setup.

Back when I started tracking the car the stock PS pump made bad groaning sounds after a few laps. I drained the system and started using Redline synthetic PS fluid and that helped a lot.
After some other projects I put on a cooler instead of the loop in the line. I haven't had any trouble with the system. I am still using the stock pulley and pump. I did drill holes in the pulley so I could quickly access the pump bolts in case it fails.
