    109 octane, however, highly recommend you get a custom tune

    I got zero benefit at the drag strip with race gas. Must have a tune to benefit.

    unless u have a tune putting racing fuel in will do nothing..now if u r n a area known for junk fuel than yes a 50/50 mix will help for just the fact of detonation..I laugh at my buddy who runs 93 Sonoco in his lawn mower says it goes faster...Waste of money

    Lol I but 94 in my lawn mower too and snow blower I figure what the heck :)

    So the car will not recognize the race gas? Does anyone know at what octane are car stops reading ? If I get a tune for race gas I have to run it all the time right ? We already sell 94 petro by my house I herd the ethanol hurts horsepower though and even though shell is only 91 it is better gas because it is pure and you actually get more Preformance ... Can anyone confirm this?

    I can't speak to racing lawn mowers, but I recently changed all the gas in my outdoor equipment during the yearly prep for spring.... When I read in the mower and pressure washer manuals, they stated specifically to run high test gas vice low test, with a recommended octane of 91+. My craftsman mower barely runs on 85 octane. All I know is that they seem to start easier, and run smoother/stronger with the higher octane gasoline.

    91 Octane has no Ethanol in it that's why it goes in the car

    Perfect example my Turbo race sled has 3 settings 280hp,320hp and 400plus hp it runs perfect with 93 on 280 but I turn the knob to 320 I need Meth to shoot with gas so it dosnt pre detonate when the boost kicks in than if I turn the knob to 400hp I need race fuel cause 93 will pre detonate even with Meth when it has 43 pounds of boost..I guess I should add all 3 of these programs are 3 different tunes on my ECU.These tunes take 1 minute to down load and work on all Arctic Cat 1100 Turbo sleds from 2010 to present..They are generic canned tunes..They have some smart guys in the Snowmobile racing world..We even have a light that flashs if the fuel is bad for what ever reason when you put some power to the engine so u know u r pre detonating and don't blow the engine..

    I disagree that a tune is needed to take advantage of a higher octane fuel. If the computer detects knock, it will pull timing. If you can keep the knock from occurring, the car will run faster. Just as an example, the difference between 91 & 93 octane was 2 MPH and 3 tents (while the density altitude was rising). You would need a tune to take "full advantage" of the higher octane fuel. But at that point, is it the tune that made the difference, or the fuel?

    Yes..... The base tune and wide band O2 sensors along with knock sensors can adjust a fair amount on their own. But if you run 106 with a stock tune....you aren't realizing an advantage. And that high of octane will have retarded timing significantly on its own. You really need a tune to take advantage of running race gas or especially E85 for that matter.

    Obviously E 85 requires a tune since it's down @ 20% in BTU's compared to gasoline. But our base tunes can't compensate, even though octane rating for E 85 is higher than most pump gas.

    I'm going to disagree to agree..Been running tunes since 2010..you can only go so far with 93 oct in a stock ECU dosent matter if you buy race fuel..But hey its your money you can buy C16 or Q16 all day but you wont be no faster than me running 93 in a stock ECU.Your point on the fuel or the tune makes it faster..I think u can call HHP or Borza and ask them..But I'm sure they will say if you want to go fast get a tune and run race fuel so it goes hand and hand ..just my 2 cents

    I agree as well. I tried race fuel a couple of times in the stock kitty at the drag strip. Made zero difference. Now, if you crap 93 octane, maybe it would make a little difference. Tune is necessary to achieve additional HP from Race Fuel.
