Default N55 Nitrous - 04-02-2017, 11:06 AM

Has anyone looked into adding a wet kit to the N55 for fixing the top end power issues? I may upgrade the stock tubro but I also would to keep my mid range power for daily driving. I happen to have a bunch of Nitrous parts laying around from when I had a wet kit on my bike back in the day. It would be great to hear how anyone else as set something up and what jet's they ran etc. I found an interesting setup that could solve fueling issues as well as help out on the Nitrous front. If anyone can share there setup that would be great.

A wet kit would just add more stress to the fuel pump. You'd need an upgrade or at bare minimum an auxiliary pump.

If your going to run it. Do it right. Stand alone fuel cell and a progressive nitrous controller.
Don't spray it where there's peak torque. Also, start small with the jetting and don't go past 35 shot. Run the fuel jet slightly richer. Start small and richer, you can always go bigger and leaner but not if it's too late. Nitrous is no different than raising boost. Remember cut nitrous between shifts and set an too lean/ too rich afr in the controller. 35 shot should net 80-90 whp. Keep meth concentration around 75/25 no more since it's a wet shot. Have meth also come on before the nitrous.

The only thing I disagree with ou on is a separate fuel cell there is no need for that

I think the DME will keep AFR in check. If you dump fuel from a separate fuel solenoid you could piss off the DME. I would just go dry. You could still run out of fuel from the stock HPFP though. To keep the HP high your going to be moving gas volumes with WG totally open that are higher than you want though. This could end in disaster quickly. Running stock turbine at high HP using chemical enhancement......

I would say only go NOS if you already have a turbo upgrade. Just my 2 cents. If you go for it keep it small and might as well go dry. If you want more then you need bigger turbo, port injection, then funny gas. At that point your turbo is maxing out your internals regardless.

Running fuel from a nitrous solenoid is no different than running additional fuel from a WMI solenoid. The only thing that concerns me about the wet shot is he could run into pooling in the intake manifold since he's running WMI... wet shot could be catastrophic in this setup. There's people tuning 100 shots in these cars... money talks bull**** walks.

did you look at that link? there is a director port setup for a pretty reasonable price that also helps with any future fueling issues.

it is my daily I would like more power for 1/4 as well as just trolling people in a grocery getter doing roll races. Again look for people that have done this in the N55. I found some interesting readying on the N54 that is helpful.


jturboawd -
I will need to part the stock turbo I may even do wheel upgrade but the point is instead of slapping on a big turbo and dealing with the lag etc associated go with a nitrous setup to make up for the fall off in top end power. I would need to figure out the potential back pressure issues and see how much that ups the EGT. Many of the n54's that are the fastest in the 1/4 use stock frame turbos and some use nitrous to push the envelope.

I did but I think youd pick either 1 or the other. Double check with company. And ask for recommendations

ive always wanted to try nos with the n54/n55. If you have fueling figured out it should not be that hard. Think ps2 + PI + 100 dry shot. At this point though I would be worried about the block as well as turbine blade failure. Shoot I would try it though. Start with a small jet and work your way up. Distribution could be a PITA. Remember we dont know per bank AFR since we only read one spot post turbofold.

What about going with a SUPER SUPER small shot per cylinder in the PI block, tied back to one solenoid. Spray 4th and 5th down the strip....

Then you could run map 7 daily, map 6 as kill map, and map 6 plus spray as the "nuclear option"

On a side note: The DME could take care of fueling adjustment through AFR. I would use a progressive controller though to make it easier for the DME.

serious though, if you do it let us know. would be nice to see the log, i would try it. If she blows you can build.

I would be doing innplace of pure 2 - I will be doing something With the stock turbo but not pure 2.

why dont you sun it anymore? Why PS2 > NOS. Why not PS2 + Meth + TBI + NOS?

I think the issue is, if you get to much above 600whp you need to be ready to build the block. If you are ready to build the block you will still have to overcome knock adjustment due to altered harmonics. Bunch of small barriers. If this was all figured out I would run 100 shot dry using individual baby gets in my PI block. Then run a CM5 50/50 at inlet pipe. Run the NOS in 3, 4, 5 gears. Was planning it out in my head last night.

Regardless, to the OP, looks like there are several data points running some decent size shots on stock turbofold, etc. I still dont recommend a wet kit, the heavy fuel mist would certainly not distribute right using a solenoid. Just upgrade the stock LPFP. You might need some octane though. Using moderate e85 + nos might be asking for trouble. Meth is pretty low viscosity, you could probably get away with running a dual meth nozzle + 1 dry NOS nozzle in the inlet pipe. Your going to get one cold a@@ inlet temp

I ran Vargas stage 2 with Meth Nos and TBI.
Then i removed Nos as my oil pump packed up. Then i installed PS2. Ive sold my Ps2 and im going GTX3582R with 0.72 exhaust AR. Bottom mount

Thank you for chiming in can you share details of your setup? Jet size controllers etc? Any dyno sheets? Glad to have someone that has done it not just a bunch of people sharing opinions that have not.

If you go over the the N54 board (or google N54 NOS) you will get some healthy discussion with actual set ups.

Hi. I ran the NX progressive controller but i did not like it. I then used a switch to arm the solinoids and then used a button to start the flow. I ran with a 100 shot dry NX express kit with cm cm7 meth nozzle and Fuel it TBI with the stage 2 lpfp. Before the TBI and Stage 2 lpfp i just ran cm14 meth jet with 100 shot dry. Best if you cant get TBI is to use dual meth. Cm7 and cm7. Will be safer than 1. I also ran e60

I have 2 dyno sheets. Ine with stage 1 vargas 19psi and Nos. 75hp shot and 1 with stage 2 vargas 19 psi and 100 shot.

@JacquesN55: Whose bottom mount are you going with? Are you changing your fueling to PI? Also, whats the main reason you prefer more boost over chemical HP?
