I would like to start offering alternator pulleys for the Cobalt's, does anyone have a stock one they would be willing to send me? In return I would be happy to ship it back along with a new aluminum replacement within 2 days. I will offer these in overdrive, underdrive, and stock sizes but they will be much lighter than stock!

I actually hinted about this over a year ago, but had to be coy since I wasn't a supporting vendor at the time. Hopefully someone can get an alternator pulley sent to me asap so I can start offering lightweight versions in any custom size you want.

Thanks,
Nate

 

Nice that would be nice someone send him one

 

I've been making them for the L67 motor for over 2 years, I think it's going to be similar to this...

 

wow, great idea!

would they cost the same as the supercharger pullys?

 

hm... interesting

 

that is all you have been saying in all your comments

 

yes, tis true. makes me sound smarter than i am lol

any idea on weight nate? that rhymed

 

I figured you would jump on this, since JBody charges like 200 bucks for theres. Now if we get this one stage 2, would the stage 2 belt pick up the slack??

 

which one? stock would be the same, overdrive would be a smaller pulley underdrive would be a larger pulley if im not mistaken

 

do you want the whole alternator or just the pulley?

 

Underdrive pullies are usually smaller

 

All I need is the alternator pulley to get dimensions from.

Nate

Underdrive crank pulleys are smaller but underdrive accessory pulleys (alternator, power steering, waterpump, etc.) are larger. It means that they take more linear belt movement for each rotation so each engine revolution it turns fewer times than stock.

Overdrive on the other hand is smaller and the point of it would be to increase the system voltage for individuals who are running large stereos and want to keep their fuel pressure up and head lights from dimming at lower engine speeds. The smaller pulley will be spun faster at the same engine RPM therefore producing more voltage at idle. When the engine is running faster the voltage regulator will kick in and limit it so you won't need to worry about burning up any electric motors.

oo ok thanks for clearing that up man, what you think the price will be for this thing? I know you havent even made one yet, but just a ball park estimate

 

cool thanks for clearing that up, i thought that was right. ever think about making a crank pulley?

 

is this the same thing that some other company came out with a little while ago but is charging way to friggin much for?

I may be interested in sending mine to ya nate.

 

:Cough: Lighter crank pulley in stock diameter! :Cough:

 

It will be priced the same as the alternator pulleys I make for the L67, 40.00

Nate

If you'd like to send it to me, pm me for the address. Whoever agrees to send it to me first will get it back within few days along with a new oversized, undersized, or stock size pulley, whatever they would like.

Nate

 

These would fit all Cobalts right?

 

Assuming they all use the same alternator...does anyone know if this is the case?

 

Same pulley...I think the LSJ one spins a different direction

 

Just as a heads up...the LSJ alternator pulley is internally clutched for movement only in one direction for some reason.

This is why turbo swap guys switch to a 2.2 alternator instead of running the 2.0L one in reverse.

 

If the pulley's the same it should obviously work for all Cobalt's

 

No, they aren't the same.

 

Damn

 

i was confused i thnk...this adds no horsepower correct?
