Does anyone have any experience running nos on antique tractors? How would you hook it up? Does it go into the carb or the manifold? What kit would you recommend? What kind of performance increase are we talking about? How many boosts can you get out of a bottle of nos?

The best way to set up your tractor would be to use a single fogger. A fogger is a y that has a nitrous inlet and a fuel inlet. The two mix and and exit a tip that sprays a fan pattern spray. Each inlet has a jet pill that allows you to adjust how much nitrous and fuel goes into the fogger. The amont of fuel in the fogger is your compensation....no need to drill out your carb jet. However, the fuel needs to be pressurized.I would consider ditching your sediment bowl for a shut off valve to a tee. Take one side to your carb, the other to an inline electric fuel pump. From the fuel pump, go to the fuel solenoid from the nitrous kit, then to the fogger. The other side takes the nitrous line from the bottle to the nitrous solenoid , and then to the fogger. The solenoids are wired together. You should have 12v power go to an arming switch, then power from that switch can go to a momentary push button switch to open the solenoids or a micro switch can be fit to contact your throttle shaft lever at full throttle. I like the momentary button switch because you have the choice to stop nitrous with out backing off the throttle. If you only get one pull.. a 2lb bottle should be plenty for a 50 - 100hp shot of nitrous. If you have the room, 10lb bottles are nice. Oh yeah, the fogger is best if tapped into the manifold. You could drill a hole and weld a nut on your air cleaner tube and spray the mixture before the carb, but there is a delay before the nitrous' effect is felt. Good Luck!

Rich, NOS is for short bursts. In my mind, Antique pulling doesn't really lend itself to this unless you are running 12MPH+ and just looking for a little at the end.

In our area our open dead weight classes can run about anything just as long as it looks safe. I know someone that runs NOS on their 560. It really is safe just as long as the proper control valves are used.

There are two different types of NOS systems. one is a plate system which is a plate between your carb and manifold with one big injector. The other is is a individual system which you have to drill your manifold and screw the injectors in just before the head. Very simple to hook up, just use an electric selinoid with a push button to activate. Just rember that nos will lean your engine out so you have to compensate with more fuel when you use it.

How do you increase the fuel mixture while making the tractor still run right when NOS isn't being used? If I drilled out the the jets on the carb how would I have any power if it runs too rich when the Nos isn't being used. Thanks

I have never seen and heard that NOS on antique tractor. i don't think it's safe. If you use it for pulling, a lot of place will not let you pull with NOS.
