Default Should I go from 150 to 200 shot?

Well I must admitt I am hooked on the damn juice. I currently running the nx wet set up from 50-150 shot with a window switch from 3000-6000 what would it take to go from 150-200, can I just change the jet only or do I need to do more. If I could get away with just changing the jets what size jets should I put on it for the gas and n20. And do you think it would be a good idea to put a 200 shot with my current set up. Read the sig. I have the nitch to go to 200, but don't want to **** up my **** by doing so.

You can go to 200 just by changing jets, and if you can pull a few degrees of timing to be safe that would be even better. There was a guy on LS1.com that had a 200 shot on a stock fuel system and stock tune. I want to go to a 200 as well from my 150, im not gonna though till I can get power to hook to the ground a bit better.

I dont remember the jetting that the guy on LS1.com had but I am sure you can search here and find out or call NX and they can tell you. Timing can be pulled with tuning software like LS1 edit or HP tuners.

A 200 shot is a .082 N / .044 F jetting (nitrous/fuel). It may vary slightly from manufacturer to manufacturer but that will get you there safely with a single nozzle. I would also pull about 6 degrees of timing.

I just want to make a pass or two on a 200 to see what the extra 50hp would do. The car is tunes already for the 150, do you think it would be to risky to bump it up to a 200 for a pass or two with out lowering my timming

No the LS1 can handle the extra 50 horses, do you already have any timing pulled in your tune?

If you already have timimg pulled then you should be ok with the 200, like I said there was a guy on the other site running a 200 wet shot on a stock tune/fuel system ands he said it worked great.

I would run 50/50 mix of pump gas and unleaded race gas to give you a nice cushion since your not sure where your timing is at.

Try to get 100 or 103 unleaded gas and listen for pinging (detonation). I believe my friend was using a 52 nitrous 31 fuel on a 200 shot nx dual nozzle kit.

The 200 jetting from NX is 78 nitrous 44 fuel.
I suggest checking your tune for knock retard and running race gas.Running a 200 shot is walking the fine line.Its doable but make sure you can afford to pay if you are going to play.

yeah, that's me. last dyno i ran showed 11.0ish across the board and going rich towards the end. this run was before i put the bassani tru-duals on. had a 3" cutout at the time.
