One trick with a 3.6-based engine is to run a lighter and less power draining alternator/fan set up. Mine is set up that way, as are quite a few of my friends.

You can also rig up a larger throttle body to get more air in, as long as you can add more fuel with a chip change or EFI tuning. I ran RSR-style hot cams at 3.8 with a 993-style intake for years. I ran 1 3/4 OD racing headers.

I switched out the 993 TB and installed an aftermarket BBK 80 mm throttle body-- about 10 mm bigger in diameter than the 993 TB. Made more power. Not very difficult to fab up. You need to have a way to interpret throttle position from the BBK's generic TPS or fab to use a 993 TPS.

I still have that TB and I am going to sell it. My current race class does not allow me to use it.
