10 AE: Stock internals S4 block 431RWHP @ 15.5psi
10 AE: Stock internals S4 block 431RWHP @ 15.5psi
Forgot to post this up.
My 10 AE with 50k original miles put down 431 RWHP and 338 torque
Stock internals, never ported. Obviously all the supporting mods. Tuned by Banzai

well the stock ports are at least good for something. I wonder what this could do with some meth. injection or race gas with 20+psi. I doubt my irons would let me find out.

who's the maker of the xhaust maniflod?
Why bother porting?
e.g., I see a 70 hp deficit @ 4K on this curve: http://www.colemanprecisionrotaries.com/
and that's w/ a 9:1 CPR FD engine.

It's A-specs kit. They make the manifold
Unported these cars make pretty good torque. For a street car I wouldn't bother porting, but you can see it starts to run out of steam around 7000. I think 400-450 RWHP is a fine number for this chassis, wheel spin is not so bad and you can put all the power to the ground. Plus it's not a parts breaker.

Never been a big fan of porting on a street car for exactly that reason, its a torque killer. Sure its easier to make HP, but it makes the car gutless unless its screaming. Now for a drag or road race car where torque doesn't really matter, that's another story entirely
