Is ok to use race gas 110 octane on 93 octane tune when using nitrous to eliminate chances of detonation or knocking when using nitrous .. Some people have told me to do it i just want to make sure

 

I wouldn't. Not unless you have a specific tuning MAP for it and have a separate tank for race gas.

 

I will need a new tune even to use C16 gas???? Some people have told me to use C16 gas on 93 tune when using nitrous only just to prevent detonation

 

You will be good most of use race gas for added safety when spraying myself included.

 

Oh thanks man is any race gas or you use only one in specific which one you use

 

Using an auxiliary cell as a dedicated fuel supply for your nitrous system is an extreme, yet proven technique. Mixing fuel in the stock fuel tank is less precise but more widely done and also a proven technique.

 

Someone correct me if I am wrong, but most 110oct race has lead in it (at least at the station I can get it at). So if you run HFC you will reduce their lifespan, as well as the life span of the O2 sensors. It will however take a few tanks fulls to do that. I was a moron and went for 100oct unleaded once at a station that regularly carried it, then the buggers swapped out to leaded 110 - I did not read carefully enough.

 

it depends whose gas you are using. i know for sure i can buy vp motorsport 109 unleaded here at the same place i fill my bottles. if you are mixing it in the tank you absolutely have to use unleaded. if you use an auxillary system thats only in use when on spray, you can use c16 or any other leaded fuel. a few seconds of a leaded fuel isnt going to ruin your o2's whereas constant running on it will.

 

So what should i do mix some 93 octane gas with 110 octane gas in my gas tank and thats it ..

 

When I used to drag race, I used to buy a few gallons of VP 109 at the strip and mixed it into the tank with 93 in it. It will be fine and I'd prefer to do that over just 93 in the tank, regardless of tune.

 

VP109 is unleaded and the R+M/2 or averaged octane rating is 105 so that can be splashed in with 93. True 110 is generally purple in color and leaded which I would not recommend mixing with unleaded (but some guys do during .25 mile runs). I will say when I accidentally ran 110 leaded on my 100oct advance timing tune the car really loved it I was spinning 1st/2nd off the spray pure NA (with an automatic). Wish I could run that all the time..lol....except for the silver dusty residue on my back end and rear tips.
