Yes killer1200 - where did you get your 180 hp figure from??? Neil's motor dynoed at 98.7hp - a very impressive result but still shy of your claimed amount. The best recent dyno I know of was for a schmick as build A15 big block on 50 mm throttle bodies and it made 120 hp at the wheels. I love what the internet does for hp claims....
So a well sorted carbed motor can get 100hp (close enough) at the wheels, say 130hp crank? Who says 200+ with boost is impossible?
if you mean crank HP then it might be possible to stretch to 250hp with a big wallet.
I was aiming for 150hp+ out of my supercharged motor once it's built, at the crank of course. it wasn't going to be too wild either, blow thru carb - intercooled, solid state conversion, cam etc & toyota SC14 with about 14psi through it (roughly 1:1)
If an ET/EXA E15ET can get 100kw at the wheels on about 15psi, I figure a boosted A14 can do 100HP at the wheels. Surely cross flow & twin cam don't make that much diff, they are just an A15 turned sideways other than that.
IIRC I calculated that 170hp would give the car the power to weight to run a 12 like my old VR4 did, which is my straight line goal
