Hey guys I have a street truck.  1962 F100 4X4 with a stroked 292 and fuel injection.  I have it tuned now really well and am about ready to give the NOS a try.  Wondering if anyone is currently using NOS or has used it and has any suggestions (does or don'ts).  I am looking at giving it a 150 shot.  Any and all opinions would be appreciated.

Robi, I have a 292 with a 312 crank 2-500 CFM carburetors using a plate 175 HP NOS system on a 1955 Tbird with a 4 speed transmission since 1985. I drive the car often and race it as well. Is your truck a stick or automatic? I would suggest that you start out with a smaller shot of maybe 75 if you can. A good electric fuel pump, filter (fuel and nitrous) is necessary also 3/8 fuel lines are a good thing. I tuned mine on a chassis dyno and found that my likes 32 degrees timing for the NOS and 36 degrees without it. When I started to spray at the 150 HP level I started to melt the spark plug ground electrode and break the insulators. Autolite 124 are a colder plug and fixed it. Bottle pressure is very important. My set up is happy when my tank pressure is 950 PSI which I control with a tank heater and regulate the pressure. If your pressure goes high on NOS the fuel ratio goes lean, not a good thing! If you have a choice be rich. Having said all that hammer the hell out of it and your back tires won't catch up till third gear.

Robi, What kind of fuel injection?

I am using a Holley Commander 950 700cfm throttle body injection.  I am running 20 psi.  Although we just made the decision today to turbo charge the engine. I have another throttle body injection kit that is a 900cfm throttle body with bigger injectors.  So we will install that first and tune it for E85 due to our high compression.  est 10:1.  We will leave the NOS on there for when we are done with the turbo set up.  I am excited for the turbo to get that low end that I need in that 4X4.  You can find some pics on my build under the street forum.  62 F100 4X4 Makeover.  Any more tips would be great, thankyou.

I think you need at least 4 97 lbs/hr injectors for about 400 hp with e85 if I read injector calculator right.



4 Injectors

400 hp needs 59 lbs/hr + 30 % for e85 and +10% for turbocharger



And of course big enough fuel supply.
