N2O hard to install?

doing things right the first time always cost more but can save you some really big $$ in the end

I never had a nitrous pressure gauge. Or a window switch. Or a bottle heater. Or any of that stuff.

If you're just joe schmoe who wants to have some fun with spray, and aren't looking to win bracket races with it, none of that stuff is necessary. Sure, you can spend thousands of dollars on a fan-dangled nitrous kit - but that defeats the point of a cheap power adder.

I wasn't implying that. A mechanical fuel pressure gauge has a fitting on the back. That fitting fails, the gauge is coming flying at your face and fuel followed by it.

There's a popular Youtube video of a 2001 Cobra blowing the throttle body and upper hat clear off the motor on the dyno. You can get hurt if you're stupid like him and you spray at too low an rpm...

ohhh, now i get what you were saying. i thought you were saying you would want more than 40PSI while running the nitrous.

ive seen taht cobra video 1000 times... its pretty crazy. what does the lower RPMs make such a huge difference?

you're moving less air at lower rpms. nitrous and fuel gets a chance to puddle and condense on the intake walls.

No, none this stuff is "neccessary" but I can't beleive you got away with spraying all of the time w/o knowing what your pressure was! To low of pressure pretty much just causes poor performance, but to high of pressure dicks's off the N20 mixture and can cause bad things to happen.

Here in Missouri, when I get out of work on a hot summer day and check my bottle pressure, it can sometimes be on up there at 1200+ (on a fresh refill) and you are just not supposed to spray when it is that high.

 

[Paul]

When did I say I didn't know what my fuel pressure was? As long as your OEM regulator is working, and you have a decent fuel pump, you'll maintain the factory fuel pressure setting. If you buy a kit that is intended for use in a particular application (i.e. 5.0L Mustang) than it will work just fine. Most kits are jetted conservatively with lots of fuel.

I live in Phoenix, which is easily as hot or hotter than 99.9% of cities in the U.S., and sprayed the hell out of several cars without all that stuff. Everyone overcomplicates everything these days.

How did anyone ever have fast cars before dyno tunes, wideband air/fuel gauges, and standalone programmers were available?

I was talking about nitrous pressure. You said in your post before that you never had a nitrous pressure gauge.

And I'm not arguing with you, I'm just simply stating that I can't believe you got away w/o knowing your nitrous pressure.

thanks for teh info


anyways, i think ill get a bottle pressure gauge, safety tube thingy mo-bobber, and i have a fuel pressure gauge...

oh plus the kit and the fuel pump. LOL!

This is why i like the NX plate system, instead of using a nozzle and spraying into the intake tube, the nx plate has like 4-5 or however many ports to spray out of.

also a good idea is to think about drilling and tapping your plenum for your nitrous nozzle but only down side is if you ever DON'T want nitrous

Nitrous pressure gauges help ensure you get a consistent hit, but they're not necessary for joe average nitrous user.

i only want N2O until i get my 4v built.

well, im for sure getting the FP gauge because i dont want it to lean out without me knowing.

also, im geting that purge tube because i want safety to be my #1 concern (as it is when doing anything on my car.)


as for the bottle blanket and all the extra stuff... ... not too interested. Ill buy a paxton for $2,000 before i buy $2,000 worth of N2O junk. lol.

 

[Paul]

If you lean out, it will be too late by the time you look at your fuel pressure gauge and react. The only way to have a preventive control in place would be to have an automatic fuel pressure cutoff switch.

good point. lol.


but I would still like to have it, how much were you looking for for that in-cabin gauge you have?

im starting to get excited now... getting my shopping list together :-D

 

[blown98gt]

+1 to leaning out, i wish i would've had a fuel pressure cutoff switch.. (and a good tuner who knew what they were doing) at 22.1 a/f mixture well 2 seconds into the 5th pull and all i have is 6 pistons and a lot of white smoke pouring out the back.

 

[95PGTTech]

a fuel pressure gauge is unnecessary - if your fuel pressure suddenly drops dangerously low, even if you were staring at the gauge your reflexes would not be fast enough to save your motor.

as is a nitrous pressure gauge - one comes in almost every kit that mounts to the bottle, that's sufficient.

 

[Paul]

I have an Autometer PN 4364. It's no longer available. It is an electric full-sweep Ultra-Lite gauge with memory.

In terms of functionality, it would most closely resemble PN 4371.

I'd sell it for $110 shipped to the lower 48 states.

[MustangChris]

how hard is it to install Paul?



also, i *would* like a window switch and a WOT switch, do these come in the kits? or are they seperate?

 

[Paul]

You have to install the fuel pressure sending unit in your fuel system somewhere, (likely the schraeder valve) and wire up the gauge.

My Nitrous Works and Compucar kits came with a WOT switch if I remember correctly.

Paul.

 

[MustangChris]

whats a schraeder valve?
