In a drag race only vehicle and you hit 100% duty cycle can you raise the fuel pressure 20% (60psi to 72psi) then reduce your MAP VE 20% accross the board and come out the same AFR? Or is their a different formula to use without starting over on the VE tables?
Thanks,

Sorry Lee but it does not work like that. Fuel pressure rise vs. delivered fuel through the injectors is not a linear equation. Check out Russ Collins' web page for an online formula.

To be accurate after any fuel changes you should put a wide band AFM to verify the change.

any concerns about increasing pressure to 70+ lbs? I am considering this.
If your VE table is dialed in you should be able to raise fuel pressure, then rescale injector flow rate table useing one of the spread sheets floating around (do a search)
then you should be good to go :)
