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.

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.

Robi, What kind of fuel injection?

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.

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.
