I am trying to see how many passes can be made on a full 10 lb bottle with spraying a 200 shot. This will tell me how many extra bottles to have on hand when I need to race.

Just guessing... 2-3?

2, 3rd run will definately fall off.

If you want to be consistant, change it every run.

yes 2 and thats it, the 3rd run will fall off and not be safe for any engine..

i'm sure 2 runs , third run the air will smoke your engine . i'm spraying 250HP.

Exactly. You're spraying enough so there's a good amount of fuel being added.. and you run out of nitrous or the pressure falls off and it goes pig rich that's a good way to lift the ringlands off the pistons.

Thanks guys. Now I know why I only gained .7 in the quarter on a 200 shot. Just bought an extra bottle last night. I think I will try to secure one more from a buddy of mine

.7 from a 200 shot? Wow I hope that thing was empty... hell I pick up a full second from a 150, I'd exepct at a minimum that much from 200 unless you're already going in the 9's on motor.

Yeah well it had a couple of dyno pulls on it. I'm going back to the track with 2 full bottles this time to get it dialed in better. It was 11.8 to 12.0 afr on the dyno pull on a full bottle, is that a lil too rich or just about right?

On the dyno I think that is o.k. or a little rich as the car should lean out a little on the track. I'd aim to get it to 12.0 to 12.2 on the dyno honestly, and just make sure your timing is back enough and you have a cold enough plug in it.

The plug in it is a br7ef gapped at .035 and the timing on the motor is at 25 degrees. When I brought it to the dyno it was at 28 degrees and Geoff at EPS put it at 25 and leaned it out on motor and it lost no power. We hit it with a 100 shot just like that and there was no knock. We then hit the 200 shot and pulled 4 degrees from that with a Lingenfelter timing controller and there was still no knock. I will weigh the bottle in a lil bit and post up the weight. Also, something I was looking at on my nitrous kit is that I have T's in my nitrous and fuel lines going to my solenoids (2 stage kit) and I think that there should be Y's there instead. I am also running 2 nozzles in the intake boot, but that is about to change soon to a plate. I don't know why I bought nozzles

I use almost exactly 2 pounds a pass on a 200 shot. Theoretically you could get approximately 5 runs, but like stated above, it's gonna get rich after 3 passes at the most, and you risk lifting the ringlands unless you have a nano setup. I run the br7ef also, gapped at .030, but only after starting with an 8 heat range and checking them. Make sure your engine likes the 7's. I also only run about 20 degrees timing. Again, after double checking everything and reading the plugs at the track, not the dyno.

Just remember nitrous is like a hot girl with an STD.You want to hit it but you are afraid of the consequences.Make sure your engine is built for a constant dosage of 200hp.You should drop between 1.5-1.8 seconds in the 1/4 from a 200 shot.Not always accurate,but a good rule of thumb is 10hp increase= .1 off your 1/4
