ls1/lt1 with nos

[84gt347]

I noticed several posts about ls1's. I've got some buddies here that dont always lay down the accurate facts about their ls1/lt1 mods. at our altitude, a good ls1 driver goes 14.10 bone stock. A good lt1 runs14.5 or 14.6. The ls1 driver has recently installed a dry nos set up for a 100 shot. The lt1 driver set up for a 75 shot. The ls1 ran a 12.20 at 112 and the lt1 driver got a 12.25 at 113. That is a lot of time off for such a small shot. I rode with the ls1 driver a couple of times. I looked at the bottle pressure and it read like 1400 psi . I read my instructions on my system and it said not to activate over 1000, and recommended 900. Is a 100 really a 100 at 1400? and does a 75 really give an lt1 that much et?
