nitrous setup on 318

i was wondering, what would you recomend on a stock bottom ended 318 as far as nitrous goes. i would like my dart to see low thirteens/high twelves on nitrous. how much could it handle? what does putting nitrous on a car entail? reccomendations?

thanks,

iD LIKE TO KNOW MYSELF! :thumleft:

Cast pistons wont like much nirtous at all. 125 horse kit is what N.O.S. says is the most you should you with them. I would stay around 75-100 tops. You'll need a good fuel system and less timing and if your crossing the end of the quarter mile at or close to red line you'll need less gearing.

i was hoping for a 100 shot actually, so that works out nicely. any ideas on specific kits. i was checking out the N.O.S. sniper kit. what about ignition/bottleheater, and what fuel system upgrades do i need to install prior to nitrous.

thanks,

The sniper kit would be ok. Id look for something adjustable incase you want to run more nitrous later. You'll need a good fuel pump and id run 3/8" line atleast.

Would it be good to run its own line and pump up to the carb?

that would be the best way, yes.

Whats the othere way?

you can just tap it in to the fuel system for the motor as long as you have a good enough fuel system.

You also need a GOOD ignition system. If you don't already have an ignition box, I suggest the Mallory Hyfire VI. It has 2-stage rev limiter, window switch, and timing retard all built in. And they are programmable with a keypad vs the 'pills' you have to buy for MSD boxes.

The window switch is important. It allows you to set a minimum and maximum rpm limit that nitrous will spray. If nitrous comes on at too low of an rpm, you can get a nitrous backfire. Turning the nitrous off just below your shift point saves wear and tear on your transmission clutch packs.

I also recommend a bottle warmer and a blanket. The setup I have is Nitrous Express. It has a pressure switch that controls the bottle warmer. Some 'optional' accessories are a remote bottle opener, dash mounted pressure gauge, and a purge solenoid. If you race at a NHRA track, you may need a blow off tube to vent to the outside of the car.

With a 100 shot, you will only get a few 1/4 mile passes on a 10lbs bottle. Depending on what kit you buy, you may be able 'upgrade' to a 15lbs bottle.

thanks for all of the advice.

after i get the performer intake on the car, ill be buying the fuel system and ignition for the nitrous...........then the fun will start happening

thanks again,
