I am watching this question with interest.

*one thought, when driving at low speed only have the throttle open a small amount and regulate the car speed by selecting whatever gear gives the desired pit road speed.

*I have experimented with power valves on gas carbs. I like the low speed performance and cleaner when staging with footbrake. With trans brake leaving where you are wide open on converter or two step I do not run a power valve.

*I do know it is common with Methanol carbs to run a primary power valve.

It may mostly come down to personal preference.

I would like to know the % of who runs what.
