Nitrous guys with standalone fuel system What fuel mix are you guys running in the main tank and the standalone fuel system. I am debating if I should run:
Option 1:
93 main and straight 110 or 116 in nitrous fuel cell
Option 2:
93/110 mix in both tanks
Option 3:
110 or 116 in both tanks

Watch the lead in the gas. I will run 100 in the stand alone and 93 in the tank from now on. After running a 93/100 leaded mix in the tank my o2 sensors were, apparently, unhappy. I'm not certain buut after a couple of tanks of 93 again, my 02 codes P0135 and P1133 if memory serves, have stopped. I only have 11.0:1 and my knock sensors are desensitized. So far detonation has not been a problem for me with the 93 tank...100 stand alone. BTW...i take it you can eat at your kitchen table again. LOL.
I'm running the purple Renegade? 100 octane fuel i think...frankly and honestly, i could be wrong about the distributor my source uses.

On the street I use VP Motorsport 109 in the stand alone and crappy California 91 octane premium gas in the main tank at 22* total timing with only a 100HP shot. For the track I am going to use motorsport 109 in the stand alone and run a 50/50% mix in the main tank, 22* timing and 150 shot on a stock short block running 11 to 11.5 AFR.
running 11 to 11.5 AFR. Last edited by Oatmeal; May 13, 2006 at 01:48 PM.

with the new ethonol fuel, go with 100-104 in the tank, and 117 nos in the stand alone.
i do either 110 in the tank, 117 in the stand alone, or 117/117 depending what i have in the garage.

id be more prone to getting a 55 gal drumb of your own 104 unleaded, save a few bucks, and leave it capped up in a shed/garage.
i know the ethonol is eating up boat gas tanks made of fiberglass, so im sure its not great for rubber

but two or three tanks after the VP110 is gone so are my codes...curiouser and curiouser
I dont know for sure...but it seems to me 110 has a higher content of lead and kills o2s quicker that C16. I dont know if the 110 relies mostly on lead for its octane boost and maybe c16 has less lead and more aromatic fluids like Toluene or what. But I hate using 110. It also seems to have the biggest impact on the tune. Using 110 I have to pull out a ton of fuel to get the right AF mix over 93. C16 does not appear to be that bad.
From my experience, using C16 mix in the main tank, with little pump, run it out at the track and nev er had an issue. However, got lazy a couple times (and put out during eliminations) with 110 in the main tank, the lower rpm driving sets the O2s into siesta time. So might be issues with either, any leaded, fuel if your not using it all at the track. In a dedicated system shouldn't be any issues.
