I am looking for a 190 or 195 pulley from a UPD harmonic balancer... I have a 180 to trade if you might want smaller or I will buy yours out right.. text or pm me... 7066815136 jimmy...

Do you have big cooling setup? You'll need something to keep intake temps down

draggbody

yes, trunk tank, water meth, single pass IC, HE, twin pumps and im working on building a killer chiller...

Wow that's a ticking time bomb you have there. Good luck

TheTherapist

I'd be interested to hear why you say that?

Do you have an 82mm TB. Going that big on pulley I would suggest bigger fuel injectors. Your cooling should be ok. Killer chiller would be great.

Do some research and you will see. I had one come apart on my engine after I was assured it was ok and tested and blah blah blah. Well it wasn't and took my crankshaft out in the process.

TheTherapist

Yeah I guess there comes a point (regardless of cooling) where there's almost too much damn boost. When my 180 first went in the car was pulling like a freight train and you could just feel the torque yanking on that crank. Before that I shaved the head off my oem harmonic balancer running an 84 supercharger pulley. Was lucky to not do any major damage.

Running a 190 or above you want more than a keyway to stop it all going pear shaped. But I'm pretty sure the op can run a crank lock with the upd cp so as long as the cooling cuts it he should be good to go? Def want that extra layer of protection with the lock or like you say you're playing dice.

I would pin ANY crank pulley.

draggbody

the crankshaft has a full machined keyway with crank extension... injectors, 82mm TB, and long tubes... i was running a 180/84 setup, but the upper pulley is **** quality and has worn out where it meets the bearing... the bearing is fine, but the pulley is wollered out... 195mm and stock upper will put me where i was before...

PM Shardul as I just got my 195 ring from him.

blackbenzz

Oh man he still sells these??? Research RTR...

03svtkiller

I have been running my 185CP without any issues for a year... As I was skeptic about the pulley as well after reading the RTR horror stories, but Shardul said these are not the same and that they are made by ASP.

layzie12g

You guys know that pinning they pulley is no big deal right????

I'd never put a pulley on a car of any size bigger then stock without pinning it.

draggbody

the 195mm are out of stock... 3-4 weeks out... contemplating replacing my upper with another one, but the way this one wore out, im skeptical whether the aftermarket pulleys will stand up to stacked pulleys...

draggbody

shardul has a 185mm, but if im spending money, i dont want to slow down...

blackbenzz

So then he admits them being faulty previously? Interesting. Does he plan on reimbursing all the people who's cars were damaged as a result?

03svtkiller

I said they are not made by RTR don't know what happend previously and who is at fault nor is it my business.

draggbody

just touching on the UPD pulley, i have ran it for approx 5k miles... i built a tool to bolt to the converter bolts and hits the oil pan... this allows me to recheck torque on the crank bolt... its been 250ft lbs every time i have checked it, its never budged... i literally had the under panels off the other day to put an O2 sensor in, i took 5 minutes extra to double check the crank bolt... however, my crank does have a full machined keyway, crank extension that pins into the end of the crank but not into the balancer, and ARP crank bolt... it runs perfectly true...
