what do you think of performance pullies. i want to know the ups and downs of them/ are they bad for your car or no, i have heard manyt different opinions and i just want to know what the fellow camaro oweners out there think. any info on them would be helpful thank you.

 

since you're new...i'll be easy on ya...

check out some of these threads

and the SEARCH fuction is a handy dandy tool

 

Ive personally seen them kill 2 altenators on LT1s(chargeing issues), but ive also heard many that were fine...It migth give ya a tenth down the track

 

If i have pullies and the jet performance chip am I going to notice a difference or not?

 

I'm gettin a set of March Racing Pullies...good? Yay or Nay?

 

the only underdrive pulley worth buying is an ASP pulley/balancer, its not a cheap stack on....
with the march pulley you have to bolt that heavy stock pulley/balancer on top of the march underrdrive pulley.

you will gain more with the reduction in rotating mass

This is what I hear...but is it worth changing from my MAC UD to the ASP?

 

I dont have my stock pully on mine, I dont have any problems. I also have the alt. overdrive pully and it charges better now then it did before. Im curious, why do you say you need bolt the stock pulley back on? I have had mine on for about 6k miles and have no problems or anything.

the march underdrive pulley is just a pulley....
the stock pulley has the balancer also, you NEED A balancer.....

What about BBK pullies they are much cheaper than march, and how much do you guys know about the jet performance chip (stage 1 for a 1994 Z28 auto trans)?

 

Good thing I saved it then. No vibrations from the motor or anything. Even have taken it to the track a couple times like that. Bummer I liked the looks of it that way. Better tell my buddy because he is running his Formula that way too.

 

they say they make a difference but no SOTP feel....Someone should do a dyno test of on them. I swear thier good for like .005hp

 

I tend to believe that a LOT of people make that error..
The piggyback pulleys have to have the stock damper put on with it.. [that's why they give you the longer bolts..]

 

jet chip = not worth the money to me anyway.....
a website (cant remember the exact name right now) did a dynotest of the piggyback type pulley (bbk, march) and it showed very minmal gains.....maybe a couple of RWHP.

there is no test on the ASP pulley though, i would like to see it, many ppl swear it will knock off .1 to .2 in the 1/4.

The jet web site shows a 23Hp gain when installing the chip on a stock 1995 camaro 5.7L Z/28, Does any one know of any one who has had a problem with the chip/does it hurt the car in any way?
