I've decided to build up an aluminum head for the next incarnation of
my motor (damn but this is getting expensive). As such, I'll need to
get valves for it.
Since I'm not restricted by any sort of class rules, I'm free to do
whatever works best for valves.
One option would be to use the biggest I can, favoring the intake
valve.
Another would be to use the biggest I can, favoring the exhuast
valve.
With the fuel and air both going through the blower, I am guessing
that the fuel and air should be pretty well mixed, better than with
natural aspiration, so flow velocity would not be as much of a
problem.
I do want the car to be drivable on the street, and I'm shooting for
more low end torque than high rpms. Even so, smaller valves could
restrict airflow, causing higher pressure in the plenum for the same
charge in the cylinder, and hence higher temperature of the charge.
What are peoples reccomendations for valves on a supercharged MGB
motor?
