OK cool thanks Adam. I scratched my head for a moment when I saw that and couldn't figure out what I was missing. Appreciate the clarification and glad it was just a case of me reading it out of context. Haven't had my coffee yet lol

 

haha I need a coffee and like 3 xanax to deal with 6Speed on a Monday morning.

 

Random question, does anyone know what a stock 991 tts does 60-130?

 

Haha no joke, you forgot the sausage McMuffins though

 

Here's ours from 2 years ago, bone stock. I don't have the file, but if I remember correctly, it was like 8.55 or something like that...

Keep in mind, our 60-130 times down in Florida generally suck. It's almost impossible to get from our shop to a good stretch of road without the car being totally hot already. That, and I am not very good at it to be honest.

 

Yeah, I think there is a skill level that goes with it much like winning at the dragstrip in heads up races irrespective of trap speed or ET and like running the car around a track faster than the next guy. So I definitely would concede that skill to him but still, we are talking .8-.9s difference from what I have done. Interestingly, that 7.5s time I posted was the first time I took the car out after the FVD stuff had been put on back in Nov 2014. That run was done without LC and I was actually running the car from a standing start with the car in sport plus and TC on. The quarter time and trap were decent too. The temp was around 78 I think and it was around 11am.

But based on his throwdown, you guys wouldn't recommend that anyone else put e85 in their car with just your OTS tune is what I am hearing. So to be fair, what long needs to do is run this again with just pump gas and maybe in the middle of the day but in the same place so we can see what difference those factors make. He still will have his good skill level for making 60-130 runs as part of the equation but that should be factored in. I just don't see how a basic stock car with a slight tune can do this much better. Even when I had the FVD on there, I know the car was making 495 or so at the wheels because I had Cobb dyno it before we removed the FVD and installed the Cobb tune. I wouldn't expect a stock car with stage I to do a lot better.

 

Thank you for getting this back on track wrs.


I'm confident that I can achieve this result again and again and again. In fact, all things equal I believe I can go quicker since my gas tank was nearly full for this run. I can shed 50 pounds just by running at 1/4 tank. And I'm happy to have a crew join me to see this in action. Same road...similar conditions.


By the way, this isn't even the fastest road. It just happens to be nearby in where I live. It's over 200 feet in elevation. I've got another road with a -1.2 slope at sea level so even better DA. But it's 20 miles away so I don't use it much and it even has more traffic risk.


By the way the e85 mix is just one variable. As has been discussed in this thread, there is a lot of little things going on that help me maximize my run. The same thing happens when I race. Which is the reason I beat other cars with more mods and more power. And I'm always on my game.


No matter what tune or mods you have, I will gladly continue to help and I can almost guarantee 6's the next time you try. Just follow the stuff I have mentioned here and then PM me some info on when you can do a run and the forecasted weather data.

 

I agree. And honestly, I think your car has a lot more in it. Based on comparably equipped cars, your times should be a lot faster. It just may be a matter of finding the right road at the right time, and getting that glory run.

I'm not playing the victim. I'm just asking you to make the distinction between longboarder (a customer) and our companies (GIAC and Champion), and to show a little respect. Obviously I'm asking too much, so there's no need to say any more about it.

 

I'll keep this very brief as it's a very busy week for me.. but banging out a few keys on the internet is not the equivalent of "S*it going down". Anyone can attempt to be a hero on the net and a forum is not the place to dedicate one's time if you have a propensity for being sensitive to blanket statements or whether a member participates in your threads or not.

Lets keep it respectable and allow any accomplishment or failure to play out on the race track. I can agree to disagree and have no intention to win at name calling. My intention is to roll up at race day with one of the fastest 991 twin turbos we can effectively engineer.

Lets all do the same and have some fun!

 

Here was mine done back about a week after I got the car back in Sep 2014 and with just the FVD exhaust and high flow cats. I took it out to the great spot I have not gone back to since. I ran a quarter and half mile all in the same sequence so I post them all. The temp was about 80 and the humidity was near 95%, it was about 9am and still a bit of fog in the air.

 

Thanks, and yes if I can find a good place to do what you suggested I will. Unfortunately, I live in the hill country and that means long flat stretches are difficult to find. There is always some undulation and FM roads are usually bad surfaces and narrow so there is risk unless it's way out in the country and you have really good visibility. In addition, there is nothing near sea level so all my DAs will be higher. The flat road I can go to is a service road below I - 45 about 12 miles north of Huntsville, Texas where I own several large tracts of land so I go out there from time to time but normally need the RR for off road activities in the woods. It's fairly safe if there are no logging trucks operating since it's an unused stretch of road for the most part. It's closer to sea level but humidity will generally be high as it's about 75 miles north of Houston.

You really are lucky because you live over on the Pacific coast in southern California which produces mainly dry conditions slightly inland and you have cool air in the morning and evening as well as access to near sea level roads too. I would just be interested if you could make the run again in the middle of the day when it's warmer and with pump gas. That would make a better comparison to some of the stuff I have as well as others probably would experience. Obviously you don't have to and traffic may be an issue later in the day so maybe what I am suggesting isn't feasible.

Hey, just to note, we are using data from our Vbox's and I am not complaining. Since we are using the same tool, we are subject to the same discrepancies. I find it very useful for us to be able to post these graphs and I give pencilgeek props for the great tools which allow us to make apples to apples comparisons at least on the data. As you can see, I have been logging data on my car for as long as I have owned it.

 

OK so on topic, I would think a better magic run would be with pump gas for sure and maybe in the daytime when most people would be able to do it. Not saying it's not possible for us to get up and get to the magic spot early but I bet most of us wouldn't be doing it.

Nonetheless, this is just an amazing and outstanding time compared to all the data I have taken from my car and that is a hell of a lot.

 

I still don't understand one thing: Adam you think your results would be better with race gas? I'd like to see a run with race gas to compare to this run, bc if that is the case then your car on race gas and tune will be equal, or better, than stage 2+ / stage 3 cars in the 60-130.

I completely understand that one run doesn't answer everything, and we had a similar scenario a few months back when my COBB stage 2 ran pretty even with SDG who had GIAC, intercoolers, diverter valves, plenum, air filter, etc. But if you are able to run a 6.5 or less in the 60-130 on race gas, that would be phenomenal. Almost begins to question the need for anything else but a tune, imho.....for most purposes.

Again, phenomenal run. Not taking anything away from that, just trying to understand this data a little more!

 

DA and track surface temps means a lot.

I am only speculating here but had I tried the run with 91 pump gas only during the day I probably would have been more than a second slower.

I'm also curious what the effect is on e25 vs race gas so my new intention is to show up to shift sector on e25 and do a couple runs until I run the tank low and then then drop in MS109 to see if my 60-130's and trap speeds improve.

Because runs don't start until the sun is up and the tarmac is hot, and the middle of nowhere Coalinga is much higher in elevation than where I live, I'm guessing that my best 60-130 is 7.5 on race and 7.7 on e25. Also think my best true vbox 1/2 mile MPH will be 160. I don't believe I would be able to break into the 160's on e25.

I have seen a variation of up to 2 seconds on the same day with my M3 doing 60-130 pulls, although that car is much more sensitive to changes in density altitude because it is supercharged with a fixed pulley. I did high 8's at the airstrip and then did a couple pulls on the way home from the event at high 6's flat slope a few hours later after the sun had set.

Thanks. I didn't log this run so I don't know if I had timing corrections. But if I did have timing corrections then yes, it could have been faster on race gas which could have prevented these corrections and helped provide more power.

I was at the wheel of those Stage 2/3 cars then I would be expecting low 6's in good DA conditions....not 6.6.

Regarding the need for more mods, hopefully there will be the chance to illustrate this at Shift Sector on Saturday. If there is a tune, exhaust, intercooler (Stage 2/3) 991 at Shift Sector I will be happy to run it. I predict the following would happen. Assuming a good even launch, I would probably hang around until maybe 100 mph, where thereafter I'm going to start suffering IAT heat soak (from the crappy stock intercoolers) and elevated EGTs (from the 600 cel cats right next to the turbos) which will cause timing corrections. The Stage 2/3 car would start to walk at have a nice 2-3 car advantage or more by the finish line.

 

Fair enough look forward to seeing you Nigel and I'll come by and shake your hand and wish you the best of luck. Obviously your car and Vincent's car are going to absolutely fly no doubt about it. We have a huge uphill battle if we are ever going to out trap the tuned McLarens which I understand are talking now about hitting close to 180. Crazy.
