I know it sounds like a alot with a stock bottom end but other people are doing it and thought I would try it for myself. I'm really trying to get my stock bottom end SS into the 9's. So for now I'm not worried about a bottom end, because I allready know that I'll be needing one soon. Right now I'm just trying to gather as much info as possible on my situation and LS1 tech is the place to do it! So anybody else out there with info. on what I'm asking for have any more opinions please fill me in!

i have never had a 2 bottle set up. I dont see the need in it, ive ran a 300 shot and it never got below 950-1000 PSI after a few 1/4 mile passes with a bottle heater. AND IT WAS COLD OUTSIDE!
That 2 bottle thing is crap, I've seen nitrous cars that consume 3.5 to 4 lbs of nitrous in a single 1/4 run get away with a single bottle and have no problems at all, 10 lb bottle.
A little pressure loss at the top might mean it goes a touch rich, which if you talk to experienced racers will tell you that little bit sometimes can save parts from burning up.
I wouldn't look at putting 2 bottles in the car unless you're spraying over 600 hp of nitrous, I know for a fact you can run 500 hp with a single bottle, but that's about the limit of what the bottle valve can flow, which is the only reason I would go to a 2 bottle setup.

As long as you have a high flowing valve on your bottle you will be fine with just one.

So basicaly what I am getting is the fact that I need a N2o controller, maybe some bigger flowing selenoids, maybe a second bottle, pull some timming, short block on the side, go from 4an to 6an lines, high flowing valve, and set of brass ***** to go with that order. Did I miss anything? Anything else I need to know?

A 150 shot got me a solid 15 mph, I'd think doubling the nitrous would add more then 10 more mph... probably never hook it off the line though
My old rule of thumb was that I hoped to pick up 80% of the shot in the form of mph, so 150 shot = like 12-13mph. So if i wacked a car with 225 I'd hope to pick up 20mph.
So you getting ready for the next track day i take it. I am too, just i will be running my new setup for the first time probably. I am still in the process of getting everything i need. Its a Nitro Daves plate system and i will be running the 150 shot at sdr. Hoping to see some 10's. Lookin foward too seeing my clone run again!
