WRC, was Flow rates for nozzles

[Pedro Haynes]

I know what you mean 
The american way of making power is by ci/cc. Check rallying, you will see
how power is made, 600 bhp from 2000cc. To suggest we follow F1 was a bit
stupid of me (I admit it) we should follow world rallying. So i have to
cahnge my motto, if they use it in rallying then i will try it.


Any one know about intale porting? I was suggested that the convex part of
the port should be a bit on the rough side (when compared to the concave
side) this creates eddy currents on the convex side and sorta (how do you
say slig shot) the air into the chamber. Like how the space probe used the
planets to gain momentum and change direction.
