AFRs and nitrous

What is the optimal range for your AFR while praying at WOT?

Gotta be careful running 10's, it IS possible for a piston to blow because it's too rich.

Little lean IMO. Shoot for 11.2 or so. It should give you a little more torque.

11.2?


Hey what fuel pressure should I base my shot off of? As in.. What's our fuel pressure at WOT on spray?

I know the psi for us is at 62 when I checked the guage that I have but I've never been able to test it at WOT during the nitrous run....

The jet calculators are way off compared to what people use if I base it on 62psi... Seems to match with the jets people use if I base it on 30psi in the jetting calculator..
