Nitrous Issues

"pussy shot" lol...yeah you raced one of my buddies stang, is this your first time to use the juice?

No, actually I have now been through 11 bottles just messing around on the street. I always run it dry and add the fuel through the wot fuel multiplier. Never had a single issue. I wanted to step it up to a 125 shot but since my injectors are only 30#, I thought going wet would keep them from running 100% duty cycle. I would be asking for 475-500 hp from a 30# squirter at 41PSI if I kept it dry. This was the first time I switched to the wet setup and it gave me fits! I also had the bottle filled at a place I do not frequent so if there is a "bad" fill, then maybe that's what happened???? I'm either going to figure this out with the set shot buy Sat or I'm buying some 42# injectors and going back to my original dry setup. If I go back dry it will be for a 150 jet.

Cool, good thread for me as im a nitrous newbie and plan on adding maybe a 100-150 shot once I get my pile going.

Im not saying spray all the way threw od on the street. Thats not safe at all.

you just need a good data log of a good pull in third gear from low rpm to high rpm. Thats easy enough to get just jumping on the high way. Or go to the track and spray from a stop threw 1st to 2nd to 3rd while data logging.

Nitrous transfer pump is a diaphram pump. its either pumping liquid nitrous or it's not. No chance of a bad fill, just a no fill. weigh your bottle.14.5 empty 24.5 is full. air doesn't weigh anything.

I rate hp on nitrous flow. A .054 pill flow with a power shot style noid, is good to burn about 100hp worth a fuel, and that can change alot with the sytems set up.

You will run out of pump long before you run out of injector.

what was the injector duty cyle on the dry shot?

[Diabolic]

I have an in tank 115lph and an inline 255 GLS XXX Walbro. My injector duty cycle was like 91% on the 100 shot. Well it was a 46 jet. I supose that may not be 100hp, but thats what Zex chart said.

I believe it was showing INJ PW at 22 at 5000 rpm.

I took 120,000 and divided it by rpm.
120000/5000=24
22/24=.91666666666
.9166666 X 100= .91% DC

I hope I did that correctly.

I figure 42# would put me at just a tad under 75% DC with a 150 dry shot and 41psi of fuel pressure.

how do you expect a 110 pump to feed a 225 pump, really?

[Diabolic]

That's what all the Gen1 Lightning guys are doing. Some of them are running into the deep 11's and high 10's with the stock intank 115 and the inline 255. I can wire it up so that both front and rear tanks come on at the same time. Then I would have 2 115's and one 255 inline running at the same time. Due to the canister style setup of the stock fuel tanks, we Gen 1 Lightning owners cannot put anything larger than a 155 pump in the tank. Those that have tried 255's have to cut the bottom out of the canister and it starves for fuel around corners with a tank 1/2 empty. Plus we get crossflow issues where one tank will cross over and fill the adjacent fuel tank because of the increase in fuel pressure.

Theres no chance that the injectors added fuel on top of the wet kit is there?

[Diabolic]

No, my NA afr is 12.7-13.1
