    the unsuspecting e93 is about to try "The Eliminator"....120 octane UNLEADED!!!!

    Click here to enlarge is what i looked like when i saw it....120 octane u ask?!...yup...unleaded too?!...yup...17.6 oxygen content?!...seems so...XXX racing fuel is gonna be in my car by this evening and we will see how well my car actually likes it...it seems the twin turbo z06 took to it VERY well in this article

    The 100-octane gas was discarded from the tank by draining it completely and filling the tank full of XXX F-118 Force unleaded gasoline. Not only did this fuel feature an octane rating of 108, but it is also oxygenated. Basically, oxygenated fuel has extra oxygen baked into its chemical structure. It is important to note that the Rockett 100-octane also contains some oxygen, but at 2.7 percent (weight) versus the XXX F-118's 17.6 percent. Like the previous test, the PCM calibration was set to the baseline/pump gas tune to see the effect of the different blend of fuel without adjusting the stoich point (14.2:1), Lambda (0.78), or timing (14-16 at WOT). Once again, the steady-state load testing showed the fuel correction was being adjusted by 14 percent. Tanner went into the computer and adjusted the target stoich point to 12.3:1 (for the new fuel), but kept the baseline timing of 14-16 degrees.
    The result with F-118 in the tank was 863 rwhp and 836 rwtq, a gain over the baseline and certainly a different outcome than the 100-octane, which had lost power when the timing remained the same. Our test car picked up power at the same timing because the F-118 added more oxygen to the combustion due to it being an oxygenated fuel. The next and final step was to increase the ignition timing for the 108-octane. Tanner dialed in 18-22 degrees at WOT and Lambda remained consistent at 0.78. The next pull netted the highest output of the day-895 rwhp and 865 rwtq.

    It should come as no surprise that such gains are capable with race fuel, even if it is of the street-friendly, unleaded variety. However, getting the most from the fuel is more than just jacking up the timing via a higher-octane rating. The fuel's stoich point is a valuable bit of information in tuning for max power. With good fuel and a proper calibration, there is no limit to building the ultimate street or race car.

    its $110 for a 5 gallon drum but its worth at least trying...if the car takes well to it, the guy said if anyone else wants it he will get rid of the drum at a discount...so i will be back with results tonight as long as it doesnt rain Click here to enlarge

    Like I said over at the other forum...be careful. I'd have a 5 gallon jug of non-oxygenated fuel in the trunk and logs out the ass just in case.

    Dude, be careful!

    Oxygenated fuels have much higher air/fuel ratio requirements than normal gasoline. While normal fuel has a stoichiometric ratio of about 14.7:1, oxygenated race fuel can have a stoichiometric ratio of less than 13.5:1. Turn those ratios over and you need 0.068 lbs fuel per lb air for pump gas and 0.074 lb fuel per lb air on race gas. Note that's a 9% increase.

    That means that on oxygenated race gas needs 9% more fuel flow than pump gas.

    Notice this part of your quote: "Like the previous test, the PCM calibration was set to the baseline/pump gas tune to see the effect of the different blend of fuel without adjusting the stoich point (14.2:1), Lambda (0.78), or timing (14-16 at WOT). Once again, the steady-state load testing showed the fuel correction was being adjusted by 14 percent. Tanner went into the computer and adjusted the target stoich point to 12.3:1 (for the new fuel), but kept the baseline timing of 14-16 degrees."

    The tuner changed the stoichiometric air fuel ratio down to 14.2 so the tune would add enough fuel. The PROcede won't know to do this unless shiv works something special up for you.

    12.3:1 is kinda crazy. That's nearly a 20% difference from pump gas.

    Your tune may think you're fine injecting fuel at a 11.0:1 ratio when your actually at more like 13.1:1 on heavily oxygenated fuel!

    i was goijg to say the same thing, to be careful. though as not as technical as you, i was just about say if its more oxygen, so would mean we need more fuel, and our fueling at those boost levels is already "iffy" i would think something verybad could happen. id hate to see you damage something

    Fuel system probably won't be able to keep up. Just stick with proven MS109 (105 RM2) or if on a budget I use Sunaco GT260 Plus (104 RM2) all the time. Click here to enlarge

    I have figured out the problem. You dont have a SB2 or the new JB3 in the car yet.


    All things aside, you have probably hit the limit on 93. It was raining and humid when we dynoed...more water in the air even acts as a bit of a cooling feature. its cold and dry out, lots of dense air....more air with same amount of given fuel will run lean, cause knock and pull timing.

    If I were you I would set the aggression down and play it safe for now. You DO have a few factors hanging in the balance and I would not like to add the repair of an engine on top of that. You keep pushing and pushing and acting like something is going to change. The only thing that is going to change is damage to the engine....stop being like my former customers that kept pushing for more power even though their engine couldnt handle it and met their untimely demise.

    Im not trying to put you down but as a customer of mine your car represents the work of my shop. I would like to keep that connection clean because as we all know if $#@! hits the fan someone will start some rumor saying I had something to do with it. I have been working on cars for the last 11 years and when I give you advice I would like you to heed it.

    Good things come to people who are patient. When you did your insanity work out you didnt lose 110 lbs overnight right? Did you expect it either?

    That will be coming in due time. We have a few other things to take care of first and I am working out a setup thats different than the rest.

    They also sell 100 oct at the pump at the Sunoco on Rt 18 North by Sams Club. I've used them a few times when I'm down that way and they charge $7.50/gal which isn't bad at all when you need some quick octane.

    VP109 is the $#@!, keep using that and then add a QUALITY meth kit to your arsenal along w the proper failsafes w the Procede. Dont skimp.

    Personally I prefer Aquamist meth kits.
