Default supercharger prep?

I have recently bought a 2001 vette and I'm not too familiar with the LS1 engines.. I bought the car with long tube headers, a cold air intake, and Borlla exhaust system. Most everything else is stock on the engine. I was wondering what I should do to prep or replace before I wanted to supercharge my car? any quick tips for a young car enthusiast?

If you buy a complete kit not much other than perhaps a larger radiator and an auxiliary transmission cooler if you have an sutomatic transmission. As long as you keep the boost level reasonable and don't drive the car like a pre-pubescent school boy it should be relatively reliable.

thank you, so the main stream superchargers all mainly fit underneath the stock as well? or will that be an addition that will have to be made? Also after adding the supercharger will it ready or open the engine up for a better capacity for a larger cam?

If you go with a roots/twinscrew type supercharger (one that sits on top of the motor, you will need a higher rise hood.

If you go with a A&A or ECS sc kit, you can use your stock hood.

Cam is not a must, but it will help. Go with a blower specific cam. It will work okay without the blower setup installed, but you want one that will take advantage of that type of setup.

What are you calling a main stream superchager? Fit under the stock what, hood? No not all of them will. I don't know about adding a supercharger to "open the engine up for a better capacity for a larger cam." quite frankly I do not even know what tha means. I'd stay away from adding a cam to supercharged engine if you want to maintain any degree of reliability. Perhaps you would be better served by posting your questions in the forced induction section.

I don't think adding a cam to a blower setup will reduce reliability. Reliability is reduced by aggressive tuning and not enough fuel.

Om my Procharger setup @ 10# of boost, it was recomended I go with an upgraded set of valve springs & pushrods, a set of 42# injectors & a good fuel pump & hotwire harness. Also good tune is a must. After 4 years & 20,000 miles, its been trouble free.

Adding 150HP in any way will absolutely reduce reliability in any mass-produced car.

I don't quite agree with you. A good build and a good driver
will not reduce the engine life on LS engines.

And to the question at hand:
You will need to consider the driveline-better tranny,clutch,
couplers,tires,etc...
Don't worry about the cam street cars will be running stock
or blower cams. You will find that you will have your hands
full with 500 rwhp stock.
Have a fun ride and good luck.

You just proved my point. You just pointed out the transmission and clutch weren't meant to handle 150 extra HP. Valve springs become another "wear" item.

Clutch is a wear item. Tires are a wear item. Valve springs should only be swapped if you have a certain type of Z06 valve spring, or if you are see valve float while in boost (if you keep the stock cam). Transmission will be fine (assuming 6 speed). Halfshafts will be OKAY unless you launch the car hard.

If he buys just a s/c kit. Keeps the recommended pulley size (doesn't go for higher boost). Buys a clutch (stock will go out quickly). Has everything professionally installed and tuned by a top tuner his car will run for a very very long time.

Good luck Mcgee! Have fun and visit the F/I section for help and advice.
