unorthadox UD Pulley

[seguin22]

Does anyone know if this fits with the stock belts? and also can some people who have installed UD pulleys tell me what kind of gains they got and what to expect. Remember im boosted too!

Thanks much, AJ

First of all, if it's an Underdrive Pulley, then no, you need a replacement belt(s). Underdrive means that the pulley is smaller(larger), so OEM belt will not work.

Secondly, if you are boosted, don't go Underdrive. Just get a lightened Crank pulley. The lighter weight will lower the rotational mass, affording a little more power. The only thing to Underdrive would be the accessories, not the crank.

Just some food for thought.

I thought the site said it was an UD crankpulley? I think I saw it at kjbmotorsports.com

Doesnt Felix have one? I know a guy on NT (BestRedRide) and im pretty sure hes got one too on his boosted Tib without any troubles. Yep I just checked and he does have one. A friend of mine here in town has a neon with a stroker motor in it, 21psi from a .50 trim and he runs an underdrive crank pulley with no troubles at all.

As we all know, boosted motors are more maintenance so if you do get one on your boosted ride then just make sure to keep an ear out for any abnormal sounds.

^^ for sure. Thanks slow for the info thats what I was looking for. Do you know what kind of gains you can expect from one of em on our motors??

it wont push you back in the seat, but its noticeable. I have the unorthadox UDP Slowing down the water pump with boost FTL... but thats just me.

When I had my XD it was my first mod and it was a nice change. It got rid of my low end bog from takeoff, for the reasonable price its a few extra ponies.
