UD Pulley

I was considering doing an underdrive pulley during my motor build on 98 WS6. Just curious if it's worth the extra few dollars to go ahead and do this...? Didn't know if there were any actual realized gains from bolting that on. If so, I figured I might as well go ahead with it while I'm doing everything else. Any ideas?

I did mine ...real easy and it gave me a SFI rating which is required. As for power you wounldn't feel it, you will need a dyno to.

I'm also assuming the SFI rating pertains to safety reqs and fire prevention? That would be on a track by track basis though, right?

you can expect a gain of 8-12 RWHP, depending on what mods you currently have.

I did mine when I did my H/C swap, it's easy, and why not give yourself those few extra ponies

We carry then entire kits that include the pulley, new bolt (either GM or arp for extra) and the correct length belts.
