ls1/lt1 with nos

84gt347 · 04-01-2003, 02:34 PM

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?

My car gets 12.40 to 12.10 on motor and 11.6 to 11.4 on spray. 100 shot at 900 to 1000psi. approx. 1 sec for a 100 shot

I have a good friend who has a LT-1 with spray. He has gears, exhuast, tuned, 100 Shot went 11.7 @ 118. And with the 150 shot went 11.3 @ 123. Maybe that helps. This was in South Florida.

I run with a lot of LS1s here who run spray. That get sick when on the spray.

On the LS-1's I have seen several run 12.9's with only a whisper lid and exhaust with a good driver. The only 14 sec ones I have seen are crappy drivers or V-6's posings . They only get roughly 1 sec per 100 shot just like everything else in my experience.

and yes at 1400 psi it will flow more N2O then expected so if the jetting is correct for 100hp at 1000 then it will be more then 100hp at 1400.
