Anyone remove the outer a/c pulley from the crank pully?

[festivaWES]

was wondering what the performance gains would benefit from removing this. I'm guessing it weights about a pound. B3/B6 engine same pulleys.

Just find a B3 pulley from a non ac car

[festivaWES]

read my post again

i said how much gain if i removed it from an a/c car. a person without a/c on a b3 isn't going to help me in determining how much i will get out of the butt dyno. i have the b6 any who

[mattswabb]

Sorry, thought you were wanting to remove it. I would say no performance increase. It is a small amount of weight. It is rotating and it does take energy to accelerate and keep it moving so in theory you will have an increase but you'll never be able to tell.

A smaller (underdrive) pulley will benefit more.

I didn't notice a difference in the aspire when I put on the a/c pulley. The only difference you'll see is when you take the belt off. A smaller base pulley would be interesting.. I wonder if any other models would work.

I did it.. there should be no detectable difference pulling "just" the pulley, but once I dumped the compressor, heavy assed brackets, condenser and lines, I did notice a difference.. like 100lbs everything combined.

[festivaWES]

i weighted everything in from condenser to compressor to all lines belt bracket...not a 100 lbs.....maybe 35 maybe

i was wondering if anyone made a balanced crank shaft pulley for it....but the crank pulley is also the harmonic balancer, so i don't know

yeah.. 100lbs was a bit much but.. Now that you commented, I went and weighed all parts and bolts.. 13lbs just from the compressor.. with everything.. it was close to 40lbs on my shipping scale. No, not 100.. but still 40lb removal on a Festiva just from the A/C is pretty good.

I had my car weighed at the track without me in it and it was 1582.4. That was stripped completely inside with 1 seat, the fiberglas hood and bumper skins, B6 w/header, no cat and no extra battery or spare.. oh.. and no tools either. I'm sure I could have lost a little more trading the Konigs for steelies.. and I still probably have 10lbs of sound dampening material in it.

Anyways 1lb wouldn't make a difference..

Edit: Just curious.. Why pursue small weight reductions on a Festiva with the B3 engine? Better mileage?.. It surely can't be performance.. The baddest B3 to date had barely 105hp.. and it cost a bundle in labor and parts to get it that way. Not trying to be an ass, but just wondering what you were up to

to answer your question, yes 1lb does make a difference for example if you say that only weighs 1lb i will keep it in my car and you do that 100 fold their is 100lb that you could of reduced from your cars wieght and even if you only take out 1 lb it still makes a difference but it is not noticeable to a human. trust me i have been reserching weight reduction in vehivles for almost a year.

Huh?? ...like talkin to my boys.. excuse me I will rephrase.. a difference that would be noticed in mpg/hp gains enough for a human to notice..

I guess you must think I'm a noob.. ..anyone else here think so??

Duh. I reread the thread.. didn't see the B6 comment when I wrote this.. cheers..

i didnt mean to be rude if you dont like me answering your questions than i wont, i am sorry for the inconvenience i have caused

[Guest]

it wasn't my question.. I was answering the original authors question and you quoted my reply... were you not replying to me?

Edit: and I wasn't trying to be rude.. but people tend to get a little cranky once they go over the 40yr old mark.. :wink:

this is what i was answering u said 1 pound would not make a difference and it does,and i explained why it does in fact matter

[Guest]

again.. then I was correct in responding with my last comment..

1lb doesn't make a difference... 1 x whatever would possibly, but 1lb ALONE will not make a difference..
