Headers, X-pipe, and exhaust will help tremendously. Also consider a heavy duty torque converter. Stock TC is the weak link in a C5 A4. Or, consider a "bulletproof" tranny from Finish Line Performance, FLP IV. There are several recent threads on this tranny rebuild.

Re: ATI procharger preperations????? (JTE)
I already have all the bolt ons but someone mentioned with 60000 miles a ring job might be suggested.Which would put me over my$ limit and I would just go h/c. Thanks for the responce though.

Re: ATI procharger preperations????? (abraham)
Ok so now I am totally confused. Some people are saying its hard on the engine and will need lots of maintenince others say 7 lbs of boost is nothing and was ment for a stock engine and not to worry. I even had someone tell me heads/cam would be harder on the car. This will probably be my last mod and I will be broke afterwards so I dont want to screw this one up. I've always loved the sound and alure of a supercharger but also love a cammed car. The s/c will produce more hp but be harder on my engine is the way I see it, but how hard on the engine will it be. I plan to keep this car for along time and dont want to blow the motor, cause I wont be able to fix it. I realy want that s/c just dont want a broken car down the line. I only race the car around town and not that often at that, what may go wrong in the future with the s/c installed and what are the chances. Help me make up my mind( this is killing me). Thank you ,

Re: ATI procharger preperations????? (MaddMagRII)
Just more confusion. I appreciate the link, thanks. If it realy is that risky then maby I should just go heads/cam, but then other people have 50000 blown miles and are fine. Still up for grabs. Am I taking a chance with the s/c , I guess thats all I want to know, cause I dont want to take any chances with the vette.

Re: ATI procharger preperations????? (abraham)
abraham, you are taking chances anytime you change anything on your car.
That being said, the supercharger will not be a problem on a well maintained and 'healthy' motor.
What becomes a problem on any motor is if you abuse it. Say you want to drag race at every other stoplight, dump the clutch and/or rev up the motor all the time racing down the street. That would be hard on any motor, regardless of how new it was.
If you drive hard everywhere, then I would have a few things taken care of bottom wise (the motor block) first. If you occasionally 'step' on it and don't drag race all the time, I don't see why it wouldn't work well. Be sure to check the timing chain, drivetrain, compression - etc, first to see if the motor is still up to snuff.
You also should upgrade your clutch after installing the supercharger. The stock one for the 350hp motor just won't take all that extra power, unless you never get on it, but who drives a corvette like a grandma anyways?
(I must have gotten up too early today, I have been working on uprgrading a clutch myself and somehow thought you had one).
I completely forgot that you had an A4. :crazy:

Re: ATI procharger preperations????? (GWPII)
thanks gwp11 finally some good info. By the way I have tha A4 and no I dont step on it at every light by any means so maybe I'll be ok. I'll have to take it up to ARE and have it checked out but what kind of $ are we talking to have it checked out while their there they might as well do the install but if I purchase the ATI first and find something wrong I'm kinda screwed. Owell I'll make up my mind soon. If the engine is up to par(which I'm sure it is) then could I have the super charger on the motor for a while to come or years down the line might they be prone to problems or create expencive problems for the motor?

Re: ATI procharger preperations????? (abraham)
These superchargers so far have proven to be reliable. All you have to remember is the oil changes. (1st) at 500 miles and then 6000 miles there after. Keep the oil filled properly and you shouldn't have any problems.
Use at least 91 octane fuel.
The belt used to run the supercharger should also be tightened properly so you won't have any problems with bearings going out prematurely.
If you want to find out how fast the supercharger turns do this:
Crank pulley dia. - divided by - supercharger pulley dia. x 4.10 x (your car's redline) = impeller speed. ATI says to not exceed 60,000 rpm.
(4.10) is for the step-up ratio the P-1SC1 has (one of the C5 kits).
