I have a wet system, nos 16020,16080 solenoids am putting on my 2000 ws6 and need some help with the jets for 50 hp, and 125 hp. the motor mods are in my sig this motor should hold 200 hp but i am only doing 125 hp. and i plan on pulling about 8 deg. of timing. any help would be appreciated. i have looked at jets in this section but dont want to gamble with being wrong on jet sizes.

you dont need to pull 8* of timing for such a "small" shot. Here is the jetting straight from the NOS instruction manual

Shot Nitrous Fuel
75 HP 41 26
100 HP 51 31
125 HP 55 35
150 HP 63 38

What TMS shortblock are you running? I'm running their 370 LQ9 with a 100 shot right now, with 3 degrees timing pulled

just a stock replacement ls1. what cam are you running and how much total timing are you running? i am running 28-30 total timing.

Gotcha! I'm running a custom cam from TMS (specs are very similar to a M3 cam) and IIRC my timing is 28 total. What made you go with a stock LS1 replacement over something else? The LS1 was more expensive than the LQ9 from what I remember

I wanted to stay with a alum block. Right now my car runs 11.88 with a DA at about 2800. Full body weight at 3500 lbs.

That's not bad for your mods, full weight, and DA. I need to get mine to the track before the season ends as well. I know I won't have enough gear on the juice though, so i'n not sure what i'm gonna do there

I have seen alot of your post, and looked at your mods and was wondering how your car ran at the track. Let me know what you run.

For sure man! So you gonna hit it with a 200 shot then, or something a little smaller?

Ok i just pulled the trigger. I just installed the 1st jets for a 75 shot to start with(41 nos,24 fuel) and pulled 4* of timing just to be safe. I have a wideband o2 sensor in my car. I got on it for a few seconds and watched the o2 sensor and the a/f was 14.0. I ran it again for a few seconds and again 14.0. I had bought jets for 125 shot and put in just the 33 fuel jet,and ran it with the 41nos, a/f went to 13.0. I dont seem to be getting enough fuel with the fuel jets recommended. I have a fpss for 50 psi and am running 58 psi while idling, not sure if it drops because i have no way of checking. So, my fuel jet is way off from what is recommended. Is my stock fuel pump too small and how much hp will it support? I am running 28 lb fuel injectors and they are maxed out with my motor combo my rwhp should be 400-420 for that. Plus i want to spray 125 shot.
