From VP's site about Import:
"Makes 5% more power than C16"
This assumes that the turbo/combo can MAKE more power. Remember, power comes from the amount of air you can push in, not fuel.
That said, 5% off of 477 = 454. So we are talking 23 hp, maybe. I bet the same boost could have been run on C16.
I'll stick to C16.
I would tend to agree as I didn't run this car very lean. We are talking 12.0 and richer afr and very conservative ignition timing numbers. The main kicker is we ran a lot of boost, the last dyno pull I watched the logger hit 35 psi then settle to about 32 psi. We have run that same amount of boost pressure on c16 without a knock event in sight. We may have been able to seek some more power with a few tweaks but we were already on the cusp of the stock clutch ability to hold the torque.
