How much do I jet up on an 8082-3 Dominator when taking a power valve out?
Then, on top of that, going from Turbo Blue (non-oxygenated) to VP -113 (oxygenated)?

Re: Jet size increase
I usually go up 6-8 jet sizes. Better to go up too high than less and too lean.

Jet remember that if you do not use the high tolerance Holley jets that going up to what you would think would be a 1 step fatter jet may not actually be richer then what you where running!
Sometimes you need to go up 2 jet sizes to really go up only 1 jet size!

You can cut a man's tongue from his mouth, but that does not mean he’s a liar, it just shows that you fear the truth he might speak about you!

I've got a jet kit from Holley. Those jets should be okay, right?mag2555 wrote: ↑Sat Sep 12, 2020 6:09 am Jet remember that if you do not use the high tolerance Holley jets that going up to what you would think would be a 1 step fatter jet may not actually be richer then what you where running!

Start with 93 square, non oxygenated fuels.
