so you have it...make a difference?

 

Yes you can tell the difference, ( I own a 5spd) the difference was more noticeable then the intake, gas milage increased then settled back, I have no regrets and my mechanic said it only took him a little less then an hour to install, for the crank and an hour for alt

 

Got an email back from kenny at CA....they will have a underdrive pulley system in about 4 weeks he said.

 

good to know ill prolly order z-specs im like 3 weeks or so. then ill go see that hhr guy

 

im interested in these. How hard is the removal of the old pulleys and installation of the new ones? Also anyone have an idea of how much they will run?

EDIT: The z-spec lightweight crank pulley runs $100

 

how much did he charge u for that alternator pully?

 

Yea if you wouldn't mind telling us how much did it cost you cause i think this would be a good mod?

 

anyone thought about making all ur pullys out of lightweight aluminum? that shouldnt be too hard ya think?

 

First most of the power gain is coming from weight not size, second i do recomend the lighten alt pully AFTER you get the crank not alone because the diff between the two is minimal the lighten alt pully complements the crank pully. They said they had to take off the alt to put the alt pully on and charged me and hour and a half 65.00 for it. THe crank pully was 45.00 nothing major take off a wheel use the pully tool then pop it out then back in.

I HAVE read good things and bad things aout z-spec so be warned they did me proper but i could have been lucky

 

uhhh another one of those companys huh? damn lol hopefully they do mine good too. did u do a lighter power steering pump pully?

 

Do much work on your car? THERES NO POWER STEERING PUMP! ITS ELECTRONIC ASSIST!

 

good to know

 

sad thing is you plan to supercharge and tune yourself. Good luck with that.

 

nah im doing other things, prolly next summer ill have a "release" well say when everything i want is done.

 

What an *******, sike just playing but hey i dont know much more then what i read here so if everybody talked about there being a flux capcitor i would take it to a shop and SAY: "damnit i know what your telling me but i am telling you i want to upgrade my flux capacitor!"

 

lol

also theres 3 pullys and a tensioner in there. what is that third pully?

 

Alternator

Crank

A/C Compressor

 

ok than has anyone done a lighter or smaller a/c compressor pullie?

 

I don't suggest going the route of lighter/under drive pullies.

Chances of you damaging the components that the pullies are driving are higher.

But have fun, work on those airbags cobalt kid

 

nah since the dealership that did it the first time, no one else wanted to but now they fixed what they did since i went to a bunch of other dealerships and they said to take it there and if they didnt doi it they would get reported, they did it again with no questions this time.

 

Upon my extensive reasearch i found that this is not true.....How ever if you plan on going beast style to lets say 300whp you are probably going to damage something this is because the stock unit is set with its damper to help balance the crank pully.
