I've been reading threads and have been thinking about buying the Unorthodox Racing Ultra S crank pulley for awhile now... and I finally ordered it couple days ago. I got it in the mail today but the sad part is, since I'll be going to Japan next week and don't have the Gates belts yet I'll have to wait until August to install it.

 

cool, how much was it?

 

It was an auction on eBay BNIB, and I won it 160shipped.

 

nice man, you are gonna like the power

 

Does adding one these make a noticeable difference?

Why didn't Acura include one like this from the factory?

 

congrats.....you'll enjoy the gains

 

i will tell firsthand and the others will tell you that there is definitely a difference. i don't know if anyone has done a dyno yet but i have off from work next week so hopefully i can go get one.

typicall when engines are designed in a factory they are overdesigned from an engineering perspective and in our case also designed to give the best balance between comfort and performance for the level of car your buying.

lightnening the crank pulleys and removing dampening materials is typically something that an auto engineer wouldn't do unless they were really designing an engine for racing purposes. even the corvette probably doesn't have a lightened crank pulley.

plus then there would be no aftermarket if everything came from the factory, and i'm sure that auto makers realize this is what keeps the circle of purchases going. cars that are tunable are desirable. at least that's the way i see it.

 

There have been recent changes to the UR pulley and what belts it uses
Contact vendor Excelerate on this forum for the latest and correct info and parts

His regular price is just above what the OP paid on ebay and he normally keeps the right parts in stock to ship together

 

Wanna pick up a 99-01 Honda grill for me?
