NOS--should I??

a 150 shot will be fine. you will need to pull about 2 degrees of timing, set it up on a wide open throttle switch as well as on a hand held button. (so both have to be pressed to spray) what pistons are in your motor? as forged would be nice but not required. if you buy a kit, you will also needto buy a bottle heater, bottle pressure guage, and a fuel pressure safety switch, and you should be set. a purge is not a requirement, its more of a need for drag raceing to get a hard hit off the start.

the biggest issue i see, is running out of nitrous halfway through the race. i was able to get about 5-6 passes out of a 10 pound bottle running a 150 shot at the drag strip. after that the bottle pressure would be so low that it was worthless. i ran all nitrousoutlet.com stuff and they have a message board where a ton of nitrous junkys hang out its worth a look to get some great info.
