Anyone try taking the A/C belt off for another .1 or so? I just wondered if anyone has ever tried it.

Yeah thats normally a easy dyno mod or "when you go to the track mod"

Is this really worth all the work?? How much do you gain?? Anything that would make you say, umm?

Not worth much. Every little bit helps though. I take it off when I put on the short belt.

I haven't been running A/C for a while now, but that's just because I did an engine swap and removed the A/C system and was too lazy to recharge it. It won't hurt anything as long as the belt is off.

I heard that it doesn't do anything because the A/C compressor pulley is free spinning when off. This would have absolutely no advantage for the work put in. As stated above, you would only be adding .1 hp. Not worth the effort for that. If you want to help it out that little, just make sure you take a **** before racing. That will help your car be more lightweight.

Just take the whole system off, it will clean up the engine bay and you will loose around 35 pounds or so off of your front end.

Dude, you caught me off-guard and made me laugh my *** off!

This might be a good table to refer to:

= .005 faster on the 1/4

= .010 faster on the 1/4

= .020 faster on the 1/4

Maybe it works something like that?

The AC belt on my car got ripped off by something so now I'm dying with this damn hot days, no difference in ET.

I had a friend in high school who would take all the belts off at the track and run with none then put them on before he left. This was on a 71 chevelle, I would imagine the water pump was worth a couple ponies as long as he didn't run the car for too long.

Free spinning or not, There still is friction, and lots of it thanks to the use of a tensioner. There are very small gains to be had, but not enough to warrant the disadvantages.

Now I could see doing this mod if I had a shorter belt. I would take off the AC and bypass the power steering. you might see a slight difference at the track but you're not gonna feel any difference. Isn't worth the time involved for such a small gain if any to do just the AC. I know of people around here that take out their air filter when weather is good and no wind. I have seen an average of .05 gain in 1/4 but I would not recommend it unless conditions are just right.
