Re: Max N/A Horsepower...
The limited crossfire is already at 10.5:1 CR
If I could find the time, and build another motor, I would go 12:1 and run on 100 octane and reflash with bosch ecu. Though it would be fun to try 14:1 but it will need a new design on the piston. Add to that Mercedes overbore sleeve you'll have a hi-compression 3.7 Liter. I found a M320 motor for $400 on the net, it's just too good to pass up.
My only worry is will I be able to crank over the engine at 12:1 or 14:1 CR with the stock starter??
