Just wanted feedback on what some of the experts on the board though about running Unorthodox Pulleys on a Greddy turbo setup. I believe the pulley setup under drives the water system by 15%. Is this an issue considernig that there is the added heat of the turbo setup? I am also running a PWR radiator.

Thoughts?

maybe fanman can chime in here, he has the exact setup...

Fanman has said hundreds of times it didn't make much of a difference. Somewhere around the tune of 1-2whp I think.

hahah thats sad...was that with the turbo or NA?

NA. I tested the units (though mine are SR Motorsports). I tested them before I got the turbo, but I don't think they will make much more of a difference. This isn't like a supercharger where we are swapping out smaller drive pullies though, so hp gain is still minimal. Even on the turbo, my temperature is rock solid (no heat ups at all). PWR Radiator & Agency Power hose work fine. The problem that I have been running into is the O2 sensor & the heat associated with my cat is tripping my CEL to blink. I suppose I'll figure a way out of this as well.

Honestly, if I were you, i would save the money, and get a set of upgraded radiator hoses, or something else. Also, add some "water wetter." Stuff works. When I put in Royal Purple 5W-30 synthetic oil I could swear my temps dropped a bit. Maybe it's just in my head.

I already have the pulleys in hand... I just wanted to know if there were any issues in regards to taxing the cooling/water system. Thanks!

I have the SR motorsport pulleys installed in my N/A car, and I get these annoying clicking sounds from time to time.

Any ideas?

The underdrive is only on the eccentric pulley and it is about 11%.

I've been debating underdrive pulleys for about a week now and it seems that the opinion on them is split, almost 50/50.

I was actually thinking about just the crank pulley and not swapping the water pump and alternator.

Any opinions out there?

If you don't have them yet, I would not suggest getting them. Use the money and getings more vital to the the car, and that have shown to work better (hi-flow cat, gauges, air intake for NA car, etc.).

Nemesis8 , the eccentric pulley is the same as the crankshaft pulley right?
So with the UR pulley set only this pulley is underdriven, the other 2 are standard diameter.

Yes if you must make that comparison.

Memesis ,regarding UR pulley set with non turbo set up, what is your opinion ,considering you have this kit, regarding responsiveness and hp.
