water injection to overcome high compression ratio

[sunnysidebb]

Hi all,

Been trying to find a way of running more than 6 psi boost on a standard Porsche 964 engine without using lower CR pistons, which is not going to happen.
I take it water injection tuned to the ecu would allow more boost hence more power.
The engine will be going into a split VW camper.
The figures are:
3.6 flat 6 engine standard.
Motec Wide band fully sequential ECU.
TCP supercharger, with 10 psi boost or more??? if not it will be standard 6psi.
Water to air IC
Sports exhaust with no cats.
Power wanted more than 400 hp if I can get around the compression Ratio.
Frank.

I think that water injection, especially aquamist, will get your power up. One thing to ask though, is can you put a thicker head gasket on the car? Not saying it's the best idea, but I know that the lexus/toyota people install thicker headgaskets to lower the CR.

The engine, tuned with the water meth, and also failsafed with boost drop, or map change, or whatever you have, should help you with power. How much, I am no expert.
