N2O hard to install?

blown98gt · May 14, 2009

just a small bit of info for your fuel pump change out

MustangChris · May 14, 2009

is that entire white thing IN my tank? do i have to remove it? lol :-(

i usually see them for 80-150 depending on brand and what not. you don't necessarily need one just helps maintain bottle pressure.

i think ill live without it, at least for a little while... the point of me doing N2O is because I dont want to spend money on a blower. lol. so i want to keep it as cheep as possible.

yes you have to pull the basket out of your tank but you don't have to unhook every line going to the tank, just a few to drop it down low enough to get the basket out, and a lot of people instead of getting a bottle heater just use a torch on it, it wont hurt the bottle any, but if you do this you "will!" need a bottle pressure gauge on it to see the pressure...

O.O .... lol.... ill do it the non-red-neck-way and get a bottle warmer a little while down the road. looks like this will take me a few months to save money up for anyways... i got credit cards and mortgage this month, then car payment next pay check. then, maybe... maybe... i can buy the kit at least and go from there. lol.

okay.

wet kit
window kit
wot switch
255lph pump

That's exactly the combination I run. Arm system. Run heater. Purge system. From that point, my only input is my foot. I worry about keeping the car straight and hitting my shift points. The WOT switch and RPM window switch do all the work, take all the thinking and room for error out of it. It was significantly more difficult driving and hitting a switch at the same time, letting off for shifts, hitting it again, worried about hitting it to early, etc. It's automatically and brainlessly controlled by my right foot.

For what it's worth, my car picked up 10whp on a mail order tune. I picked up 4whp more on the dyno on 93. From that, I picked up 21whp going to VP103. I picked up 14whp untuned on 103 versus tuned on 103 with the nitrous tune. Yes, a tune has always been well worth it to me. My nitrous tune was six degrees less timing than my VP103 tune, my tuner was able to add 3 more degrees back in and about three tenths leaner because he had it on the dyno rather than the initial mail order nitrous tune based off my VP103 dyno.

thanks for the input...

im just affraid if i start buying all sorts of parts for it ill forget something and ill have a $200.00 window switch that i need to instal... lol. ya know? i have NO idea what all i need for a 100% NHRA legal, safe, complete, wet kit...

what about fuel pressure? how do i get a guage into the cabin with it still being NHRA legal?

Paul · May 15, 2009

Get a NHRA rulebook and you'll be all set. You'll need a blowdown tube if the bottle isn't firewalled from the passenger compartment.

Get an electric fuel pressure gauge if you want to mount it inside the car.

MustangChris · May 15, 2009

how do i set up an electric one? i hope i bought an electric one. lol

Paul · May 15, 2009

If it was cheap, it's a mechanical gauge. If it was a couple hundred bucks, it's electric.

Electric ones have sending units and wires, mechanical routes fuel directly into the gauge.

hm... so an autometer at $35.00 probably wasnt an electric gauge? lol.

95PGTTech · May 15, 2009

no. I would not be comfortable having 40 psi of fuel pressure staring me in the face, no matter how much confidence I have in my installation abilities. failures still happen.

MustangChris · May 17, 2009

how much fuel pressure should be run when doing a wet kit?

contrary to popular "Fast and Furious" beliefs Nitrous will not explode. There wont be some huge explosion. I have seen nitrous incidents but, they have all been either user error or nothing that could've hurt the driver.

i've seen nitrous explode UNDER the hood and cause a hood to fly off but once again no one was even remotely close to being hurt, and the only serious nitrous accident i've seen was a guy left his bottle heater on (bottle was in the trunk) and it shot out the back of his trunk (folded the trunk in half) out the garage door (blew it apart) and went on.. lol but i can assure you no blow down tube or proper safety stuff was on the last one.

I'd recommend keeping the tank in the trunk, you can run the hose through the cabin (as a lot of ppl do) but best way is under the car.

95PGTTech · May 17, 2009

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?

Paul · May 18, 2009

I have an Autometer Ultra-Lite electric fuel pressure gauge with high/low memory that I'm selling if you're interested... but it's more than $35. :grin:

MustangChris · May 18, 2009

high low memory? ... am i gunna cry after you tell me how much? lol.

have you done a write-up on how to install it yet Paul?

just curious.

95_BOSS · May 18, 2009

I was skimming over posts and so I may have missed it, but I didn't see anybody talking about spark plugs.

I spray my 95' alot with the 100 shot and so I'm also running a 1 step colder plug gapped at .035". IMO, I would
definitly do this. With your 4.6L, I would throw some NGK TR-6's in there. And like many said, a N2O pressure gauge is a must because you should only spray between 900-1050psi. And a window switch is also good to have so that you only spray between 3000-6000rpm. I personally like to play a little safe and I spray between 3500-5800
