Short belt mod ?
 

Has anyone seen any real performance gains for the short belt mod, is it actually worth the money to get the belt just for the track...anyone do any back to back runs?

also posted in the drag racing forum

nobody tried this mod or is this a stupid question i am not seeing :bang:

The short belt mod can get you up to 7 RWHP dyno proven since it bypasses the power steering. You use a belt with a part# 538K6. Dont forget to remove the lower bolt on your alternator or you'll shred the belt.

I am not quite sure what a short belt mod is...this is the first Ive heard of it. Can someone explain it to me? Thanks!

you use a shorter belt so the only pullys you use are, tensioner, crank, altenator, water pump. no power steering

Oh ok, so you have no power steering with this mod. Thanks!

Also, I've never run my ac belt eigther. If you spin the ac pulley by hand that thing is heavy! It must be such a relief for the engine not to rev it up every gear.

When I took that belt off I could feel the difference the first time I drove it. I never use the ac anyway.

I agree with this. My A/C belt snapped last Saturday, and I could tell the difference right away. At the same time I also have more drag going on with the Prochager pulley. Either way I felt the difference.

what if i have an asp 25% Ud pulley is it still the same part number

The part number is for a ASP pulley. I'm not sure if ASP makes pullies with different underdrive ratios, maybe someone can chime in?

thanks

I think there is two different sizes of belts one for stock and some brand pully and then anotherr for a nother name brand pully not sure witch thow
