nos how many runs on a bottle
 

I'm looking into a nos kit and I was wondering how long a 10lb. bottle would last at the track. I usually make between 6 to 10 runs when I go to the track I was thinking about 75 horse kit

Thanks for the help

i usually switch bottles after 5 runs with a 150shot, thats with me on the nitrous the whole time, never letting off the gas (powershifting on the spray)

not sure but if I had the 75 shot would I use half as much give or take. I;m just looking into it so any info would be great. I was thinking nitrous because of the cost and I would have the extra power and could put the extra money towards the rest ou the car.

Thanks for the response

Using a 75 shot I would get 7 good runs till the pressure was to low for a safe mixture. I was using a wet system and I did not want to wash out the cylinders with raw fuel and no nitrous to help burn it up. When I was using the gas I figured it at 2 minutes a bottle. In my area $4 lb it was easy to spend $40 on a bottle fill just on Wednesday night racing.
