I'm trying to be realistic. As much as I'd like to see this car on the
track, I am really looking for streetable power. So I am doing things more
from the perspective of how the car is going to do with everyday driving the
main priority. I don't want to end up with something that runs sloppy or
evewn compromized on the bottom end and below 5K just so I can get good dyno
numbers once in the engines liftetime or that perhaps that like to see how
it does on a drag-strip, however tempting.
I guess if I ever feel the need, that is what the high octane is about. I
would think if I want to go over 300HP, then I could install a water
Question: Isn't the MC-2 compression similar to the 3B?

torque in the MC2 isn't really noticeable if you can make another 50hp in
the power band. I dynoed (in my MC2'd 80tq) about 250 wheel HP on street
gas, and about 300 WHP with 1/2 100 octane, timing was maxxed out on the
