Sorry, I ment to say I am using the NOS Pro Shot Fogger Setup. Our class limits us to 1 bottle and it must be a 10lb bottle. Currently we are using anywhere from 3-4lb per pass I was wrong in the first comment. We are changing the bottle on everyrun. We are using 1 run per 1 bottle. Trying to get to a 4.40 in the 1/8th in a 2500lb door car. Mainly if I use a larger jet will if fall off on the top end or is 1 bottle enogh for an 1/8th mile. Probably going to try it this weekend if all goes well.
