what kind of fuel pressure is necessary to support a 150shot of nitrous on my bolt on ls1. I currently spray 125wet with a stock fuel pump, I know I need to replace it, and I plan on doing so with a racetronix unit. Just curious about this thanks.

I would say nothing less than 50 PSI....GM recommends 58 PSI under all operating conditions.

You should be able to hold 58psi on the bottle.

Depending on your power level, your regulator may not be able to keep up & pressure may still drop when you first hit the bottle.

What is your rwhp on or off the bottle?

I also stock the Racetronix kits & provide tech support (including night & weekends) to my customers.
