Does anyone use nitrous instead of co2 for their SLE? Thanks in advance.

that way you don't have to run the extra weight of a CO2 or air setup if you are already have nitrous... duh

i fill my "co2" bottles with nitrous, and have been doing it for years. It seems to me that nitrous lasts longer than c02. A lot of nitrous cars are starting to plumb air shifters to the nitrous supply line and putting an inline regulator on so they don't have to carry multiple bottles.

If you're running nitrous, consistent pressure is one of the things that is most sought after. Why increase the chance of a leak or inconsistent pressure just because of a short cut? CO2 is cheap, easy and doesn't weigh much. DUH! Roll Eyes

Use a Nano system and pressure problems are solved.

Car I just bought had the nitrous line T'd off to a regulator then it fed the shifter and chute release solenoids. Only problem I saw with this is you have to have the nitrous bottle on every pass.

Now we are thinking! Nitrous is like American Express or car insurance ...don't leave home without it!

Cool

I was looking at the IHRA rule book for TD and noticed a Throttle Stop is not legal. I have been using a SLE and the needed Throttle Stop for over a decade?
Is this being enforced?

I have used SLE and Nitrous many times NO ISSUE at all.

Years ago my dad had a fire in the shutdown Right after the 1/4 mile, back when we ran 1/4. He had just put some sort of k&n velocity adapter on the carb. When he lifted it sucked fuel through the vents, flooded and backfired. The fire melted the air line and extinguished the inferno.

Just something to consider.

As long as you have enough nitrous pressure before the run you purge it down to the desired pressure right before the run... Roll Eyes

I can't speak for others, but I run right at the min weight and wouldn't want to add any weight, even though it "doesn't weigh that much" that's still more than nothing. if you add CO2 you have another bottle to remember to turn on. it would be easier for me to just run it off the nitrous, that way if I hit the purge button and nothing comes out I know to open the bottle. I'm already filling nitrous bottles and even if I used the nitrous for air launcher chutes, an air shifter, and a SLE it still wouldn't use more than an ounce or two of nitrous and the cost of it would be marginal. Roll Eyes

to me the only reason not to would be potential of fire. if you burn through a line, especially in the driver compartment, that fire just got a great big oxygen source.

We have run it both ways, when we are running the nitrous on the car we can tee off of it with a regulator and a standard soloniod to sut off the nitrous flow, it will get turned on when the power gets turned on, that way it always works. On the dragster right now I have CO2 but woulnd't hesitate to put N2O in it if I didn't have any CO2.

Utilized in both ways, its amazing at how much the PSI doesnt move with shifter and chutes.

Our car doesn't do a burnout without a bottle.. lol...

Save weight and steps.

Hey Don, do you run one regulator for the Chutes and shifter? What PSI do you regulate it down to? do you just use the regular pushlock stuff or special lines since it's nitrous?

One regulator that splits one line off to shifter and chute

Believe it or not basically using a Throttle Stop Regulator and just plastic line.

I only use a air release, I run 6lb Simpson Spring chutes...

Another question - does your SLE loose pressure sitting in the trailer during the week?
