PS Pulley sizing

How do you figure out what size power steering pulley you need?

I ordered a PSC TC pump rated for 1600psi and am wondering if I need a different pulley or if my stock one will work.
I know a small pulley spins faster obviously, but just wondering if there is a calculator for this so I don’t burn up a new pump.

thanks.

TC pumps have a max rpm of 5-6k I think. Gonna need to do a bit of math to figure out what pulley keeps you around that limit at redline where I suspect that motor will spend some of it's time. What size is the drive pulley?

talked to PSC. They said it can handle Motor RPM's of 6500 if the PS pulley is an inch smaller than the crank.
So with the stock crank pulley being about 6-5/8 that puts the max at 7655rpm with the PS pulley being at 5-5/8

I feel like that's a little high...

with a 6in pulley it goes down to 7177 RPM on the PS pulley

If you can find a 6" pulley I'd try that first, just gonna blow down low in the rocks for output.

Heroes pin it.
 
I'd run whatever pulley comes stock on your rig. The pump that's attached to it survived all the way until now, it'll be fine for the future.

As long as the pulley fits I’ll try that. But if the stock pump was rated for higher RPM, then I’ll blow out the new pump if it’s rated lower.

you have the pulley. Measure it and the crank pulley and do the maths, since you know the rev limit on the TC pump, you'll know if it'll be ok or not..
