Suffering from brain death. Whats the secondary power valve worth in jet size, 4 numbers? Im building another since these quads suck and I dont have another secondary block drilled for a power valve. Is it 4 numbers, I dont remember. Stupid old age.

I thought it was 6, but not sure.

according to book 6

It will be wortth 6 to 10 jet sizes depending on the size of the holes in the PVCR (Power Valve Channel Restrictors) Starting out 6 sizes should be a safe guess.
