i am ready to finally add a 100-125HP nitrous shot to my 350HO...w/vortecs, 268xe, holley 600 v/c, RPM, unilite, flowtechs to flows, TH350 to 3.42 posi.

a couple of speed guys were telling me to up my carb to a 750v/c and add a 70gph pump....another told me to add an electric pump and a 5/8 line.

will my unilite be ok with such a simple nitrous set-up?

any experienced nitrous guys and penix....i'd love to hear from you!

czar :cool:

Why would you need to up your carb size to run nitrous? You wouldn't.

Nitrous systmes supply it's own air and fuel.

mark,

i have no idea why the "veteran" speed guy told me to up my 600v/c to a 750 v/c.he also said i would have to get my fuel line to a 5/8. he also said that a mech pump pushing 70gph would be ok.is this true?

It might be okay, but I woudldn't run it that way. Keep you fuel system for you engine the way it is with you mechanical fuel pump. Run another fuel line and supply the nitrous plate with a electric fuel pump. This will insure enough fuel, and consitant fuel.

Mechanical pumps don't pump consitantly, your engine still runs fine because it has a steady fuel supply from you carb bowls. 3/8" line for you nitrous fuel supply should work fine.

I agree with Mark about the Fuel system. Electric dedicated pump for anything 100hp+.

I also believe the 750 would wake that motor up, particularly on spray. J.M.O.
