Ok first off, there is a difference between these little letters, HP and WHP. HP= Horsepower and WHP= Wheel Horse Power. Its a big difference trust me. That means that our 170hp cars only have around 135whp i believe, its somewhere close to that. Now someone correct me if i'm wrong but RSM advertises an 80 HP gain for $5000 dollars. That is the biggest waste of money anyone could ever spend. That means your spending $62.5 dollars per HP. Now heres the alternative, HP Racing (a company) who sells a turbo kit for the grand am (which is the sister car to the alero) which hasn't been test fitted for the alero yet, but theoretically should fit, you just have drive your car to chicago to be tuned by the guys @ DHP. Anyways, but their kit is $3,000 and you get 220whp @ 5lbs and 254 @ 9 lbs. So you do the math, who has the better deal.
Turbochargers and Superchargers are very technical add-ons, its not something i can just make a list for you to go out and by, it requires knowledge, experience and expertice on our cars and the chargers themselves to make this kit work. That is why there are only so few boosted vehicles.
If you really want to check it out still, the site is
www.turbochargedpower.com, but please do not hassle the guys at HP if you do not plan on buying, we have plenty of people including myself working on getting this kit fitted so it can be advertised for the alero.
Honestly if your just looking for a fast way to hook up your car and something that is less technical, you might want to try nitrous. It is technical yes, but it takes way less time to learn and there are more people on here using it then turbochargers or superchargers, so they can help you out, and third its way cheaper and easier to get into your car.
