Hello all!
Having trouble trying to find an answer..I have a swap which is using a dead head system running 2000 LS1 injectors at 70 psi fuel pressure.. how would i adjust my ifr table to compensate with the higher fuel pressure ?
Thank you for your help
Use a calculator, should be straight forward.

Put 58psi for old, 70 for new. The flow rate at 58psi, then hit calculate.
I'd just run the GM spec fuel pressure so you don't have to change anything. Or get larger injectors if you are trying to squeeze more from small injectors. Running more fuel pressure could change how the injector works when that's 12-15psi over what they are rated for.
Ok great thanks for the info
How would I scale that in the ifr table with a dead head system..? I find my new flow rate is 30.8lbs/hr which converts to 3.88grams/sec.. but i would need a linear scaling due to no frpr
