i installed the pulley at the same time i had the jwt flywheel and clutch installed. i noticed a big difference in the way the car pulls. that could be completely from the lightweight flywheel though.

 

I just seen unorthodox racing's new website and they are claiming a 9-13 hp gain with this pulley??

They really know how to "stretch" the truth and big time...So much of a stretch that its a straight up lie.

 

We all know half of product adds are lies to sell.. Claims of 15whp on almost every mod.. This is why young modders think that if they add an intake "5whp" + True dual "20whp" + headers "10whp" + test pipes "15whp" + reflash "15whp"= 65whp gained ..

 

I don't understand this product at all. In theory i should feel something and there shoudl be a gain right? I mean if the pulley is lighter, then less power is needed to roate it and the extra power can be transfereed to the wheels but for some reason no change in teh way the car feels or on the dyno

 

It needs to be an underdrive crank pulley I guess.

 

Not sure if its just me or not, but I swear I felt a difference when i installed mine, lol. Maybe a difference from manual / auto tranny, doubt it though. Iono, maybe you had a bad dyno day... more humid or hot from before you tested it? but then again, might just be me lol.

 

IDK every car is differnet but on my car i didn't feel anything and dynos didn't show anything. Temperture and huidity were relativly similir if not it was a little cooler that day.

 

Pulleys are another reason for Independent Dynos

 

Did you by any chance WEIGH each of the pulley's?

 

I held both in my hand and the UR or was so much lighter 1.25 lbs vs like 6.25 pounds. Something similiar to that but even that huge difference sent yield results...

 

:/

 

that's weird.

works well with DE though.
