GIAC Stg 1 60-130 in 6.653 -0.5 slope
Congrats that's an excellent run! Amazing what a little E85 can do lol
To be fair though, not exactly a level playing field until a Cobb car runs E85. Correct? I don't know enough about the different fuel types and power production but I would imagine your results with race fuel and race map would be similar to others (both Cobb and Giac) and therefore this is not a typical result, would that be accurate?
With that being said, I can't wait for the platform to be able to run E85 safely and consistently, I think that's a game changer!

Thanks. I think the e25 made a difference, but it wasn't a huge difference. I believe it would have been faster (from more timing advance) on race gas.
Now that GIAC solved the fuel system limitation on the 3.8 DI platform, I can see the future to include a GIAC Flex Fuel product where you can run full e85. Although it might not need more than e40-e50 since we don't have a large cam profile compared to other cars like GTRs that can take advantage of very high ethanol contents.
This is actually the exact opposite slope needed for an optimal run.
The highest negative slope should be at the end of the run. Why? Take a moment to look at your G-forces at the beginning of the run compared to the end of the run.
Yup you got it. The car is accelerating slower at 130 than it is at 60. Therefore to optimize your run the highest negative slope needs to come at the end of the run to "help the car out". You don't need negative slope at the beginning...you need it at the end.

Looks like the GIAC OTS map is already as good as it gets. Keep in mind that I have only done one 60-130 run. This isn't the best run...this is my only run. I haven't tried on race gas yet. This time will be improved upon.
Hard to believe? Things may be even harder to believe when I posterize ur little girly friends with a lot more mods. I got stock turbos with both cars...nuthin' to lose man.

all this sound sooooo desperate for attention is patetic lol, the real thing that your saying is that all your giac buddy's doesn't know how to drive and the pay for a Tune and hardware that is not what you have, so giac sold dreams to all of them lolOh and I believe is very childish of you when you said "posterize ur little girly friends"
I'm not responsable if they awnser a little strong lol

If you have a problem with longboarder that's totally fine, but the negative comments about GIAC or Champion are totally uncalled for, especially since neither of us have made any negative comments towards you.

Understand your point, but his the one saying giac this giac that, I just saying that his looking like someone that doesn't know what its talking about... If someone buy the giac OTS and made a "dedicated 60-130 run" and doesn't get near his 6.6 what do you think that customer will think? But hey, sorry if in any way I offend any of giac and champion guys, was not my intetion. 
P.S. Don't forget that Jeff "918 Spyder" holds the record of stock turbos now

Well once again a thread gets completely off track and nothing is gained. I think Adam has a non-repeatable event here but we need him to try it again under the same conditions. I have a car with proven high dyno numbers and I have shown repeated runs of times that are all .8-.9s slower than this. Of course the conditions weren't as ideal but I was running both from a standing start and from a roll and in both cases the best times were similar and a good .9s slower than what Adam has obtained with the e85.
I actually do have a 7.5s 60-130 run that was done on a different road with a small positive slope on 93 pump gas. It was on the way to the county road. Still, my best time is just slightly lower than 7.5 on a mix of race and pump at the drag strip. I don't understand how a rolling start can make this kind of difference and the rolling times I have from the race track are all not any better. However, if the negative slope makes that large a difference, then it's going to be really tough to make any kind of claims about times without everyone running under the same conditions at the same place.
I for one am just interested to understand how it is that a car with nothing but a tune can run this fast using e85. What exactly was the factor in this extremely fast time? I would like to see Adam run this again under similar conditions on the same road with pump gas and see what the time is that way.
Here is his throwdown
I want to know what the reason for the run is and it's a lot less likely the E85 plus tune than it is the conditions and the slope but we won't know until Adam runs again under a variety of different conditions on the same road. I would like to be able to find a road like the one he used for this great number where it's safe to make a run, lucky Adam for having one in is vicinity.

Is this directed towards me and Nigel? By process of elimination, I can't think of anyone else you may be referencing so maybe you could clarify for us.
Only a basketball player can posterize someone else and you have to be able to dunk in order to do it. I don't think anyone here qualifies. I posterized some people when I was young and my son can still do it but not many people in the world are physically capable of posterizing another person so it's just trash talk. In my day we just said we dunked over the other guy.

Not to beat a dead horse but again this is not accurate. Stock turbo record is a 9.71 @ 143 by 918Spyder. He also ran a 10.12 @ 137 without nitrous. This was done just last week on a COBB Accessport.

But you get my point...longboarder isn't sitting here bashing Cobb directly, or bashing Sam directly. He may have his disagreements with members, but never directly mentions you guys. Webcar takes every opportunity possible to mention GIAC and Champion...even if the thread has nothing to do with us. If the tables were turned you'd be saying the same thing. It's just a matter or respect. That's all I'm asking for.
Surely we can filter the noise out. I asked a couple of questions right away and found that long has some experience mixing E85 in his fuel so he was willing to take that risk. Apparently this isn't something you guys would recommend? I am of course curious as to what exactly the factors are that contributed to this outstanding run with no mods other than a tune and the fuel change.
Of course not you Chris. You have always been a class act and conduct yourself professionally on these forums. I am stoked for you that you car is running well. You would never speak to me like this either directly or indirectly and I would never speak to you like that.
However you are right about Nigel. Won't touch my threads yet likes to make underhanded snide childish remarks elsewhere. So you know what...if I'm provoked, s*it is going down. Take a look at this little gem from yesterday. It's an indirect response to this very thread but posted in another thread. Hey Nigel...if I'm interpreting this wrong and your reference to "femininity" wasn't me, then I apologize.

Correct. This is not something I would recommend to a customer with our OTS tune, and longboarder even stated in his first post that GIAC was not thrilled by this and advised against it. But he has a lot of experience with that fuel mixture in past cars...and, well...it's his car so he's free to do whatever he wants with it.

What contributed to the run is hard to say. But as longboarder admitted, I think it's a combination of a few things. When he did the run, the temp when he made the run, the slope of the road he used, and the new fuel mixture. Sometimes the planets all line up. Also, many people don't realize there's a certain skill to 60-130 times. Two people in the same car could get drastically different times. Longboarder happens to be pretty good at it.
