Saleen SC folks - new waterpump pulley?

[Burke]

Hey fellas

bare with me here, as before the S197 came into my life, I knew nothing about working on my own cars

Anyway, I just recently replaced the saleen plastic idler pulley with the stock oem metal one and changed my belt to the gates 108 - I am running the 3.6 pulley.

I saw this at Brenspeed

and remembered seeing (I think) some folks online talking about swapping out their waterpump pulley.... and wondered if this was what they did.

anyone here with a series VI running a different wp pulley wanna chime in, that would be great. Thanks!!

Is that what they are showing in that pic above or is that another one?

 

[Hawgman]

Looks like the Ford V10 pulley in the pic to me.

I run that pulley from brenspeed. It definatly makes the belt a little tighter. Didn't really notice much, for the price what the hell right?

Dave I am putting on this pully next week...... PM me later I can tell you more about it.

Hey Dave......i've been running the v10 pulley for about a year now. The larger wp pulley causes the belt to wrap the sc pulley a little more. Helps prevent belt slip. With a 3.6 pulley you're prob fine with the stock wp pulley, but if you drop to a smaller sc pulley you may want to throw this on........

Tom you don't need that pulley on a Vortech SC. They use those on Saleen's SC.

Yep.

 

[scramblr]

Yep.

LOL...

Does this larger pulley reduce the volume of waterflow from the waterpump?

I would expect it to slow down the waterpump and that might cause issues in hot climates....

Just curious.

Yes it does. However, the V10 W/P pulley still has a larger O/D than the Steeda underdrive W/P pulley. That combined with the OEM diameter C/S pulley yields a faster water pump RPM than the Steeda underdrive pulleys. No cooling system issues with the V10 W/P pulley.

That's my understanding too. Hey tmcolegr, off topic but quick question- what psi are you seeing with the 3.0 pulley?

14 psi

GREAT - thanks for that bit of info, man

[and I found an old post of yours I had printed out a while back from Mod Fords where you talked about the belt/V10 pulley combo when you first put it on.]

14 psi

Holy shit......

 

[tmcolegr]

Holy shit......

Againstallodds is running 15-16 psi on the stock bottom end.

I/W 10% C/S pulley with a 3.2" S/C pulley.

 

[tom281]

I was thinking of running a 3.2 pulley to see around 10, maybe 11psi. But if you're seeing 14 with the 3.0 then the 3.2 should be around 12 I would think.

That can depend on some things:
air temps, air density, exhaust configuration, etc. With my wife's car which has a 3.2" pulley I'm seeing max boost of 11.8 psi.

I've got 10 psi on a 3.4" pulley. I think you're right about the 3.2 (11.5 psi).
