I've got a old compucar WET nitrous kit i want to toss into the 87 shelby z. I would slowly like to up the shot to 100 if possable. I'll be running 16-18psu boost pressure along with the N2O.

I've got more then enough fuel to support a big shot. shooting for some good 1/8 mile times ;)

Check out this calculator.

Use your base fuel pressure for the calculations. That means your static fuel pressure with the vaccuum line to the regulator disconnected.

Sorry i forgot the link.

That's a calculator. Don't use the fuel jets as gospel. I found I needed much larger fuel jets that what was recommended.

Didn't we have this as a sticky?
