I am seriously thinking about supercharging my Euro 560SEL.

The motor is in excellent shape at 80k miles.

I am considering either intercooling or the possibility of decompressing the engine. The only feasibly method of decompression would have to be in the head and gasket area.

I think either intercooling or decompression and no intercooler will allow me to run up to 10psi of boost which is about where I want to run. 400hp at the crank would be my mark, up 100 from the 300 currently.

Does anyone have any thoughts or information around this? I was thinking about pulling the heads and getting the block o-ringed with custom thick head gaskets. Does this work? Pulling the motor and fitting lower compression pistons would probably break the bank.

Matt.
