What gains with a short belt? What are the gains in horsepower and/or 1/4 mile, when using a short belt? Do you think that it is cheating with the numbers? Some shops advertise their dyno numbers (using a short belt) and others don't.

Re: What gains with a short belt? I don't have any Dyno numbers for you, but I do have a 1/4 mile time. I tried for the longest time to get into the 12's until I heard of it. I was running a consistant 13.1 or 13.2. I must have put in over 20 passes trying for 12's. I heard about the short belt from a friend at the track. He let me take it off of his car at the track and give it a try. I came up with the time you see below, 12.9 at 110 mph. Call it dumb luck, but 12.9's are the norm for me now. I think that the shortbelt gave me that extra umph... that I needed. The belt is a 522K6 Kelly/Springfield from Autozone. Good luck

Re: What gains with a short belt? Like i stated im my post i gained right at a .1/1mph with mine 2 weeks ago with the same 60fts. before the short belt pass. I have personally seen a guy in a basicly stock 00Z28 gain 8rwhp/5rwtq with the short belt. It works!

Re: What gains with a short belt? The shortbelt bypasses the power steering pump. Its worth about 3 rwhp on the dyno, and about 0.03-0.04 seconds at the track. If you are not a consistent driver or do not have a consistent car, you will probably never notice a difference.

Re: What gains with a short belt? Has anyone removed the a/c belt to see if there was any gain? I know that there shouldn't be any drag since no1 races with their a/c on anyway but I was just wondering is anyone has tried it.

Re: What gains with a short belt? ha ha, if people are dissin on the short belt, youre gonna have an ear-full about the a/c belt. ive noticed a performance gain on both. in the winter i run no a/c belt, its a noticable gain, but not enough to sweat it out in the summer. at the track, the shortbelt took away about 1 tenth in the 1/8 for me. anytime you get one tenth for $10 its worth it.
alright if i did it i would change it out at the track anyway. i just know with the ford power steering pumps if u try and turn the wheels with the car off you can screw up th pump
I didn't seem to gain anything from it the few times I've tried it...I didn't even bother trying it the night I ran 12.2s, maybe I should've, 12.1s would've been nice. 
Even with skinnies on and pumped up you WILL still notice it, it's not impossible to steer of course but it is definitely a higher effort, especially at the end of the track on those 180 degree turns LOL.
