dont get me wrong a 150 shot is plenty! I'm still happy with how my car performs with the 150 and i'm sure you'll love it as well. But i'm just to used to it now and i need more! haha this 200shot isnt a 100% decision for me, thats why i started this thread so i could get some input from other guys that are doing it on a stock LS1 and how they like it. I'm installing a cam here pretty soon so i'll see how i like the 150 combined with the cam before i make my decision to go bigger.

 

Just curious what gas do you put in the standalone and what jets sizes are you runnin for that 200?

 

Probably at least 100 octane. I would run C16 in the cell if I had a standalone.

The nitrous jet for a 200 shot would be around a 0.072. The fuel jet should be figured out accordingly on a dyno or by reading the plugs.

 

I ran 150HP for 3 years. Stock bottom end with rod bolts. 346 with heads, cam and intake, with 36lb inj. 3-5 bottles a week, (I'm a sick F---!). The last 3 races I went to I threw 200 at it. It only picked up a couple of tenths as we found not the fuel, but the factory SS ehaust held me back, finally spinning #6 rod bearing. I had 1 3/4" Dynatech hedders with their 3" y-pipe and high flow cats. I have the Walbro 255 with the Casper Elec. wire. I think if it was ramped up or staged and the exhaust issue was addressed, it's possible the motor would last longer. 200HP is alot off the line all the time.

 

I run 110 octane in the stand alone and i run 2 nozzles,100 shot on each.The universle E.F.I. NOS kit nozzles are only good to a 150 shot(140 realisticly lol).Because of the stand alone system i run(its a lil different than most) i run a square jet pattern on my set up, been that way for 4 yrs. now and seems to work pretty good.On the 200 shot(100 on each nozzle)i run a square jet of 47 NO2 and 47 on the fuel.

 

I am running 100 octane with my 100 shot now as it is... cheap insurance really.

 

is that a 108 leaded fuel? how does it affect the O2's if so it is leaded fuel..?

 

Leaded. I've been through a few O2 sensors, but it's cool....I only payed for two. You get 2 new ones from Autozone the first time one goes out on ya.....they have a 12 month warantee. As long as you use enough nitrous, one of them is gonna die again before that 12 months is up. That vicious cycle will continue, and you will continue to get them replaced for free from Autozone. I also completely gutted my high flow cats with the use of nitrous and leaded fuel.

 

Just curious as to what you mean by a square jet pattern?? I also run a dual nozzle wet setup with N.O.S nozzles and would like to step it up to a 200.

I've been spraying a 150 shot for years on a heads/cam car with stock bottom end. Been debating a lot whether to try out the 200 pills. This year just might be the year, lol

 

i got my car stock at 74k added at cam at 98k then spray at 100k. i use the hsw dry plate used the dual .44 jets for 5 or so bottles. now i use dual .48 jets havent sprayed them yet

 

Square jet pattern= 47 fuel and 47 on N20.
