Am getting ready to do a setup and had a few questions. I am wanting to run between a 100-150 shot. My car is 100% stock, down to the paper filters.

At this level, will stock timing be ok, or is that pushing it? If it seems too much, i was considering a seperate fuel system that ran xyelene or something similar. I have autotap, but haven't spent much time with it, does this have a readout to tell me if the knock sensors are picking anything up?

Also, where do you guys have your nozzle? Where did you tap in for fuel. DerekFSU, you say you run a "modified 60 shot" i think, how is it modified?


Thanks for the help,

Only input I have is that Kleemann told me the stock ECU runs super rich so I think you are actually in better shape with stock ECU than modded which leans it out....

DWTBOSS scared the crap outta me this weekend as he is now having trouble with his baby on the bottle.....could be a million other things though..ESP etc.

Best of luck....keep us updated.

lol I have one crazy friend he has a e210 e55 and I swear he uses nos likes its a push me when ever you want button. He has 105,000 miles now and not a single hint of any problems. every 1000 miles he changes his oil tho.

I realize that i'm not talking about a small shot, since it'll actually be much more on the supercharged motor, and that there aren't alot of other people doing it, and mistakes are VERY expensive. With that said, i'm still ready to try it.

On my old camaro i realized i was a little nitrous happy when i was spraying on the way to work. For this car its going to be for the track, occasional highway race, and for wow factor.

I thought that it might be a little much for stock timing, that's why i was considering the 117 octane. We'll see what everyone else has to say.

MikaelSS, I assume you're asking about W211 E55?
I am wondering where folks are installing the nozzles.

MikaelSS

Yes, an '05. That was one of my questions, i also wondered where people were tapping in the ignition for the window switch.

VP Fuels C16 works very well in stand-alone nitrous applications. Just don't run it through the gas tank . . . it'll foul up your O2s in a hurry.

medici78

Either way, its gonna run through the O2 sensors as it is still combusted and the O2 sensors are located downstream in the exhaust system.

MikaelSS

If i were going to put it in the tank i'd use xylene (home depot paint thinner). Its 117 octane and lead free. I may use the same if i go with a stand alone fuel system.

You'd think so, but it's been my experience that this isn't the case. The limited volume of leaded fuel adding additional enrichment for the nitrous hasn't ever caused a problem on the numerous vehicles I've installed nitrous with stand-alone fuel systems on.

medici78

Actually, you're right it does make sense. It's a smaller volume for a much shorter period of time. I know I had to replace the O2 sensor on my singled Supra since I tried to always run at least a little C16 in it at all times.

I saw an article somewhere where the writers tested a pair of O2 sensors that were "allegedly" lead-safe. I forget their exact process, but i think it included driving the car on leaded fuels with before and after dynos, comparing power and readings of the car's O2s to a wideband on the dyno . . .

Point being, the sensors stood up very well to leaded fuel . . . now if I can just dig up the article I can find out what sensors they tested.

I think most are using a dry system which limits the amount of nitro you can use. Stock fuel curve is not an issue with anything under 80.

Sorry Mikael but I really don't know squat about my system. My installer is a master MB tech and did it all. I'll get you his contact info if you'd like.
