nitrous on a big block

[Todd in Vancouver]

I ran a bigger fogger system on my SBC and this is what I did;

I ran a new 1/2" fuel line and pick up for my carbs with a dedicated electric pump. This in itself really helped the car as the factory line could not deliver enough gas for my set up.



Then, I added a second electric fuel pump that only turned on when I "armed" my NOS and I used the smaller factory fuel line to feed my NOS system. I plumbed fuel pressure gauges for both and made sure I had everything set up right. There are a couple books out there about using NOS that are helpful.

This set-up worked well for me for years on my street car which later on in years became my dedicated race only car using the same system. Never had an issue but as others stated do your homework and I'd start with a book all about NOS.

BTW it is an absolute hoot to use and I will be adding a kit to my current build as well just for kicks and giggles.
