Any really smart engine guys here? I don't know enough about engines to even make an educated guess on if this is even possible. So, you have a water cooled flat 6 M96/97 engine. How much HP can you realistically get from this without super or turbocharging. Pistons, Cam, Boring, Exhaust, flash and these are not bolt on obviously. How can you push this 355 hp (shaft) engine to 440 hp (shaft) without blowers? Just a thought question if anyone cares.
Mine is technically a "stage 1.5" engine. I don't have the ported heads that a "stage 2" build has (a-la Sneaky Pete's FSI 4.0, I believe), but I do have the higher-than-stock compression pistons and forged rods, Nickies cylinder liners, etc.
I'll be happy if headers, full exhaust, X51 intake manifold or IPD plenum and GT3 throttle body with a 997.2 airbox and a retune will get me to OEM X51 power at the crank. So ... 15-20 more horsepower? I'm cautiously optimistic, but then again, I need to stop spending money on this car ...
