I'm wondering if anybody knows how much hp a single Walbro 255 can handle with nitrous? My current set up is stock bottom end 355 (forged pistons), LE3 heads/LE ported intake, COMP XFI 280 cam, SVO 30# injectors, in-tank 255lph, Nitrous Works wet shot/plate jetted @ 175, yadda yadda yadda. Made 365rwhp on motor through a Yank SS3600/FLT Stage 4/Moser 9", we didn't get to dyno it on spray (I know...dyno numbers don't mean much, just wanted to show it's not making huge power n/a). I have a couple grudge races coming up and I'd like to toss a fogger on for a 2nd stage to add a little more "just in case" as long as my fuel system can handle it. Opinions?

Play it safe and run a seperate fuel system for spray or run twin 255'.

Depends on your fuel pressure really. Most pumps can move more volume at a lower pressure.

I probably will over the winter, but until then if I can safely get by with a single in tank for just this weekend I'd like to add more powa

Mine's at 45 psi

why not put 200 jets in the plate?

I thought about that too, but I'd like a separate stage for "just in case I need a little more". Grudge racing isn't all about going as fast as you can, it's about going just a little faster than the other guy

I'm also planning on doing some back to back tests of plate vs fogger next year, and may be switching if the fogger works better, and possibly doing two stages both foggers

I won't be making nearly that much, even on both kits

527 SAE rwhp here on the 100 shot with a Walbro 255 and my own wiring.

I ran two 255's on my 95 Z with a 150 shot. Mainly because if the pump dies when the spray is on, boom.

Dave at Nitrous Outlet told me that the Walbro 255 and the harness is more than enough.

Wow you're making some power n/a. Im guessing I'd be about there with another 75 on top of my 175. I'd like to only do another 50, doesn't sound like it would be too risky.

Thanks guys
