Unorthodox Racing vs. Mantapart

Don't know if this has been covered before but to those of you with underdrive pullies.

Which are better? The Unorthodox Racing or the Mantapart ones.

The UR says you have to buy a belt seperate, but the mantapart ones says it comes with a belt as well as an alternator pully.

Just wondering the difference and if anyone has either one.... just give me some feedback.

Here is the link to the mantapart one.

Mantapart Pullies

OP 1530C Billet Crank Power Pulley: This setup includes a small diameter billet aluminum crank pulley and matching belt. This is a non-balancer type for serious competition or track use only.

OP 1530C $175.00


and BTW, im looking at this for track use, i guess maybe the UR pully was more for daily drivers. :thumbsup:

UR pullies are better

What about the RSM Pullies? They say those only weigh 12 oz, compared to the Unorthodox Racing Pullies at 14 oz.

The only difference I see is price, RSM is cheaper, and the options of color.

Any opinions on RSM vs Unorthodox?

[Oldsman]

well 2 oz isn't going to really do anything.

RSM is a good company and so is UR. It is more of a matter of which one is easier for you to afford.

the only thing to think about is RSM just started making those pullies and UR has been making them for quite awhile.
