N2o Users?

I ran it on my iron headed 340 it would run 7.75 off the bottle in the 1/8 mile and about 7.00 on the bottle at about 100mph in 1/8 mile. I think it was 150 shot I tried a bigger nitrous shot but it was not worth any more HP with my engine. Its been about 5 years since then so I don't remember all the specifics.
