I would consider getting the heater kit with the pressure transducer rather than one that just goes by heat.

I would add a fancy ignition box with rev limit, nitrous retard, window switches, the Mallory 685 is popular with the LT1 crowd, not sure it it will work for you or not.

Window switches are an important but overlooked safety item. Trigger the system too early and the cylinder pressure can be too much for the pistons, and you can have it shut off before the shift so you save wear on the tranny. After the shift it will reactive because you are back in the window.

I am researching the bottle myself, just afraid to bite that bullet till I can afford a rollbar and have begun a shortblock.

You also (in addition to the ignition box retard) want to turn the NOS off about 200 RPM before your motor hits the ignition box's Rev Limiter, because you donít want to have a manifold full of oxidized fuel ready to explode on a back fire.

125 isn't enough to need all the fancy, and expensive stuff. Just back the timing off a few degrees and floor it!LOL If you dont hear pinging than it wont hurt itself.

No one ever stays at 125 Laughing

Mine started out as a 75 horse with a mini bottle hidden in the air cleaner. I'm up to 250 horse shot now. This stuff is worse than drugs. Embarassed

I too like the transducer heater setup - just remember to cut the bottle on first. I had the NOS heater setup with the thermostat and it works good on a full bottle, but the temperature needs to be a little higher as the bottle empties so I took the thermostat out and operated it manually - only forgot about it once and ran the pressure up to about 1800 or so Shocked . Before that at the track we would put the bottle under the hood of the tow vehicle to warm it up - never liked the blow torch thing I see so many people doing - scary. Fuel and NOS gauges are nice, but most important to me is a hobbs switch to shut everything off if fuel pressure drops - it is one accessory I won't run a nitrous system without. I agree with Knarley, until the addiction really gets to you, do exactly what he said and you should be fine - I'd pull out about 5 degrees and run 93 and let 'er eat - assuming it's a street motor.

Yes all you have to do is take 4 degrees per 100 hp of nos.that will be a good starting point.you can then add timing by the heat in the strap.

As far as the AN fittings, they are brutally expensive. I go to a hydraulic supply house locally and get all my stuff. They are made by Parker and they have most of the same fittings - steel instead of aluminum though - for a fraction of the cost. I use a teflon lined braided hose they have for all of my stuff and it too is much cheaper per foot. You can either have them crimp the fittings on or they have some fittings that can be put on at home. Clay

Yup, I can remember when people first started using AN fittings because they were a cheap solution. AN stands for Army-Navy or Mil Spec for aviation use, and they used to be for sale used, for scrap prices at the aviation salvage yards once upon a time.

There used to be a guy in Sefner (Don Garlits old home town) that recycled aluminum out of Vietnam war helicopters that he had shipped back. Had three acres of old shot up Hueys and Bell helicopters in his back yard on SR579 half mile south of the old Tampa drag strip (I-4 & SR 579). Could go there and unbolt anything and pay scrap price for it.

Clay is right about the steel fittings being the way to go, and the teflon lined hose never rots from the fuel like regular steel braded hose does. I wont use anything else!
