Newbie to nitrous

Same shit either way, just for looks really, and vibration resistance, but in this application its not really a big deal.

My new fancy liquid filled gauge, my buddy was staring at it, and I was wondering wtf he was doing, and he says "dude your new gauge is busted" lol.... fun stuff.



As had been said, no real advantage in this application tho.

Yours is the closest to making a difference, engine vibes won't affect the needle on a liquid filled one anywhere near as much as a dry one.

Mine, and most people I know, have the gauge mounted on the bottle or in sight in the car, so the added cost is purely for show.

I know I bought the liquid filled one because I liked it better, no reason otherwise

Yeah, wont be that important tho, I am ripping the bottle heater out and going with a NANO system, so bottle pressure will be constant in all temps... its gonna stay there tho because it looks cool under the hood and will let me know when my bottles open? lol

First you have to get the lines right lol your first one is "He's got enought NOS to blow himself up...... period" your second one should be "Now me and the mad scientist have to rip apart the block and replace the piston rings you fried"

yes....i know.... its sad i know this

Who cares if its bad its funny lol

i have a friend with a 2.2 and has a wet kit and wants to run a 75 shot. what fuel/nitrous jets should he use? he has an intake and full exhauat

[Preston]

umm go to any nitrous site call the people and ask them what jets are used for a 75 shot

or use google
42 NITROUS jet and 28 FUEL

i pulled taht off in a matter of 30 seconds could be wrong it was off a focus forum lol

[bulls'ss]

i have looked and cant find the correct jet sizes

[ItalianJoe1]

as above, a 75 shot is appx a 40-42 nitrous jet and a 26-28 fuel. Depends on which manufacturer you go to. I would say a 42 is right about perfect, as a 50 shot is a 37/22 and 100 is 46/30, and mid 20's on the fuel side. Our cars run higher fuel pressure than what is considered normal, so default fuel jetting will be on the rich side. Holley includes jet size/hp listings in most of thier instruction sheets, all of which are available on thier website for free.

From what I've read our cars run 58psi fuel pressure.

According to dynotune, a 75 shot running 1100psi bottle pressure, we would use a 41 jet for nitrous and a 22 jet for fuel.

Don't run at 1100 psi, stay at 950-1000 where it should be.

I'd run a 24 fuel jet to stay on the safe side until you dyno. If it's too rich, drop down a fuel jet size and try again.

I spray 1st-4th traction sucks with even radials with traction hopin for low 13's maybe high twelves if I ever get traction I hate the wot stuff I have a button 8-10bottles still running great

I run a 25 fuel jet with my hundred instead of a 24 with my hundred shot it runs a lil rich but I well

According to dyno tune for a 100 shot at 58psi fuel pressure u run a 47 and a 24

What AFR does that actually give you?

[mmcgee123]

10.8-1-11.3-1 depending on temp and what pressure the bottle is when its like 60 and 950 psi about 11.4-1 which is almost perfect
