manual tranny calibration # is 88961331, auto is 88961332

the reflash will cost you an extra $80-$100 for the dealer to do it.

So total cost for the whole setup is under $2500 if you install it.

You should mention that this will only work on the '00 and up 2.4L equipped Aleros. The '99 won't work with it properly; the starter is bigger and gets in the way of the supercharger, some have an EGR valve that the newer years don't have and the PCM is different meaning the flash won't work on it. It also will not work on the ECOTEC engine or the 3400 V6, in case anyone was wondering.

actually most of the 99's have the smaller starter and no egr. However they can not be reflashed, so you just need to do your own fuel mods to compensate for the added air.

this post from j-body.org is a good resource for any pre 2k cars wanting to go the gm s/c route.

So does anybody actually have it installed? Is there a noticeable difference? I am looking to get one, just would hate to get all said and done and have it not make a difference.

NoSweat83 has one but he hasn't been on forever...... looks damn nice too

Yes the pully size matters. Im not sure what all the specs are but I know the smaller pully is better depending on the application.

Oldsman 04-10-2007 10:36 PM

stock PSI is 4-5psi

max psi is 8-10psi after that very ineffiecent.

basically you can go down one or two pully size i think it is a 2.7 or 2.6 but that is it

there's a lot more information about this supercharger on www.j-body.org. the main idea behind the gmpp supercharger is that it is RELIABLE. this means you aren't going to need to change out your internals before installing it. it also means that gm will service the part. if you go turbo, you may have to change the internals to handle the boost. as far as numbers, it depends entirely on what supporting mods you have. i've heard numbers from 205 HP to 220 HP. most people don't JUST install the supercharger. most upgrade the exhaust, maybe cams, intake....

a supercharger is "boostin it"

Cliff8928 04-11-2007 01:09 PM

also.. what's the increase in torque with the supercharger?

Yes it basically makes your alero comparable to cobalt ss and it looks nice. I will have to repost pics.

Pimpalero03 04-11-2007 04:55 PM

its a good idea i think. reliable power and that is more then enough power. aleros are pretty quick already.

number1alero 04-11-2007 05:07 PM

hell of a deal even at 40hp gain, without the labor install, thats only $37 for 1hp, which is a steal compared to some mods where that can be $100+ per 1hp for some mods

Pimpalero03 04-11-2007 06:14 PM

i paid more then that to bag out my alero. this is a sweet set up

2fst4u 04-11-2007 06:28 PM

plus, there's a guy on j-body.org that will reflash your ecu with a better tune than the gm one. he also removes the speed limiter and throws in a few other goodies. all for 180 shipped.
