smaller belt modification...
smaller belt modification... How do you do this modification? I saw it done when I was reading about the S.A.M. SS and they claimed something like 3-4 tenths I think?? <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> I know its only for the track cause it bypasses the power steering and such. Any info on how to route it or a belt size # for it?
Thanks,
Mike

Re: smaller belt modification... Just to let you know, that article was a misprint. The gain from the power steering bypass is .03-.04. You'll have to remove one of your alternator bolts to do it, and if you have an A4 you'll have to tie wrap your trans cooler lines down. You'll see what I'm talking about when you try to install the shorter belt. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> My belt is 52.2" long, but a 52" belt will work just as well. Once you run the belt under the water pump pulley and then go up over the small pulley, you'll go straight down to the alternator. It will bypass the power steering altogether. The rest of the belt goes on like the stock one.

Re: smaller belt modification... What Trevor said.
It's definitely got some gain, but the load on the pump is minimal when you're running in a straight line.
I would avoid unless you're looking to eeek out the last hundredths. I do it 50% of the time. The others I get lazy.

Re: smaller belt modification... Trevor - Is this mod worth? Is it hard to do? Yeah I do have an A4. I am running 8.1 and really really want to be in the 7's. (1/8 of course <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> )

Re: smaller belt modification... As you get to faster and faster speeds, the heavier steering will feel better at the big end of the track. Wont be as twitchy.
If you're running 8.1s and haven't already did the following, I'd do it:
remove back seat
run with low gas (less than a 1/4)
remove or at least disconnect the front swaybar
take any junk/tool boxes, jack and spare out of the car
air up front tires really high
short belt has consistently shown to drop .03 or so in the 1/4, so not much in the 1/8th at all. At the same time, it would suck to run 8.00 or 8.01

Re: smaller belt modification... my results with short belt are with mixed feelings, the engine accellerates quicker and my traction gets worse off the line and on gear changes, this doesnt help me, but with traction i believe it would be worth a 10th and 1mph,i can feel the difference in engine load with and without.
