Ive been driving my car with the supercharger on for around 2000 miles. Other then the ICV grommet popping out, everything is running smoothly. Even tho everything is driving fine, i still feel like the car reliability went down the drain compared to stock. Everything is more sensitive and some day, something will happen.

I am running 11psi so its not considered "low boost". I am planning on what I would like to do for next year in 2007. This year, I am pretty much done. I am just going to get a new clutch and straight pipes/exhaust. Next year, I am aiming for around 450 WHP so I would like to reinforce this motor as much as possible.

I know for sure, I will need to lower my compression. I definitely need thicker/stronger head gaskets. Would I need new pistons and new rods? or is this something I do not need to worry about if im not going to make more then 500 WHP.

My plans are:

schrick or sunbelt cams
aftercooler (must have)
thicker head gaskets

what else should I add on to my list? thanks in advance

Maybe a water injection system or whatever it's called, to help cool things down.

the water injection is installed already. Here are the mods I have:

M50 intake manifold
42# injectors
Aquamist water injection
porsche 3.5 HFM
Custom AA tuning
bumped to 11 psi with the right pulleys

If there`s enough clearance, have the block O-ringed....this will eliminate most head-gasket problems. These bottom-ends are plenty strong, and should handle 450-500 HP (at the crank) without blowing up.

Regards,
Bob

yeah but above 500 might cause some problems...
