Hello, I was wondering if anybody could help me out. I have a 2003 281sc coupe with 2000 miles on it. I just noticed a rather loud clack sound coming from supercharger either pulley or snout when the engine is running. I never noticed it before. It sounds like maybe a bad bearing. The nearest saleen dealership is a 2 hour drive so I am trying to find out if this is normal for the Lysholm supercharger and I am just noticing it now or is it a warranty issue? Also my car is currently stock and I was wondering if anybody has changed out the 3.27 gears for either 3.55 or 3.73, would I be able to hook up with these other gears or would I just be spinning the wheels? Thanks in advance for your help

well for the gear question my Saleen came with the 3.55 option and I could hook great, then I swapped for 3.73 and still hooked fine, only I was quicker, now I am going to be running a lot of HP so I just swapped the 3.55's back in so my first gear is still useable. I can't help you on the blower though. birdieman4 could give you some good insight, he is the Saleen Master

Ok Venom, here's the deal. That series 4 Lysholm blower on your car is relatively noisy and clacky at idle. This is perfectly normal. It has always done this to an extent since you have owned it, right? If you bring the idle up by pulling the throttle cable while you are under the hood, the noise will disappear. Also, that blower isn't even broken in all the way yet. By 3-4 thousand miles it will be, and will quiet down just a touch. Your car will get faster in the next 1-2 k miles. As far as gears, if you keep your car as it is, 3.55's are fine. 3.73's are still ok, but I think you will get the most drivability out of the 3.55's. -But i'm not saying don't get 3.77's if you want to be agressive.
Oh, and check your internal blower oil level to make sure it is full. There is a crescent 1/2'' bolt on the top front of your blower. If you unscrew this and pull the bolt out, there is a clever little dipstick attatched underneath with grating on one side. On this side you can check the blower for proper oil level, just like you would a car's oil.
