how many runs will you get out of a 10 # bottle on a 300 shot

Without knowing your combo I would think that if you could get a 2nd pass out of it it would start to go rich because of inconsistent pressure.

2 1/8 or 1 1/4 pass if you want the tune to say consistant.

Agree with above. If I don't purge much, I can BARELY get 3 quarter mile passes out of a 10 lb with a 230 shot (28n/24f jets). Often the 3rd pass is a bit slower, so realistically, I only get 2 solid passes with that shot.

I'd be you'd be borderline on a 2nd pass with the bigger shot. BTW, that's on a 352" engine running high 10s on motor, mid 9s on bottle.

I just installed a data logger and you can really see the pressure delta between start and finish drop much faster on each successive pass. Mine drops anout 40psi on packed cylinder first pass, about 100psi on second pass, and 150psi on third pass. That's with a 900 psi starting point on each pass. If you want to runs balls out on every pass, stay with only a pass or two before top-off. If just running for fun, get a third pass.

well im trying to figure out how much a buddy of mine is spraying he says 300 but he never made a pull pass on the 2 run and the first pass was not all there-

i think he is lying - besides he is running a nos controller - so its only coming on 10% and up car goes 8:60,s :peeing
