has anyone used the Unorthodox Racing Ultra SC lightweight crank pulley on there supercharged max?? is it worth the 200 bucks?? does it add hp?

 

you will loose boost

 

You will lose boost for sure. Search udp for the answers why!

 

its not a underdrive pulley!! its the unorthadox sc pulley its a crank pulley made for supercharged cars

 

Yes, we know of the stock sized lightened crank pulley.
Back in the day ptatohed installed one and lost boost. They soon realized (ptatohed, The Wizard) the pullies they recieved were a bit smaller then OEM sized. They had worked with UR to develop correct sized lightened crank pullies,.. not sure if they ever installed them and if they did if they saw any gains etc.
May want to contact them.

 

i tried to contact wizard sent him a pm but yet to hear from him.

 

soo unorthadox redesigned that crank pulley?

 

He will, give him time. The guy is full of usefull info and always eager to help.


from what I read, yes thanks to the info provided by the Wizard and etc.

 

Received your PM. Sorry for the delayed reply. Figure I might as well post here for all to see/learn.

I now have a very nice and expensive paper weight. Even with the new and correctly sized pulley, both Ptatohed and I STILL lost 2psi on the boost gauge, and the car felt noticeably slower. Two different cars, same end result.


Yup. Read all about it here. I never thought in a million years I'd be able to convince a big company like UR to redesign a pulley for a small Maxima community. Unfortunately, all the hard work, phone calls etc didn't pay off!!

 

soo pulley is garbage?? stay with stock?

 

yes stock is better

 

I thought I made that pretty clear.....

 

keep wiping with Windex for that streak free crystal clear shine

 

how does that make any sense? two pulley of the same size on the crank will be still be the same hieght regardless of how much they weigh.

does that not seem odd to you?

 

Not following you here. The UR pulley was initially the wrong size (smaller). Supposed to be stock size, just lighter.

The weight of the pulley is not in question.
