have for improvement(1410 on the 12.3 at 114 you have shows you could have ran faster et) i get 1350 to 1360 range with my allroad. you get in that range and it should be in the 11's(et) and then maybe you'll believe it. if you happened to see the nhra event from chicago this weekend and looked at the pro stock times, those guys all ran right around 6.6 @ 206 mph(every one of them) and the person who won the race had the best reaction time.

that had a 1.765 60'. I'll assume you'll agree that's pretty good. Since I can somehow manage that, I'm pretty capable of making the rest of the shifts as well. Where do you propose I could have made the run quicker?

Is this theory one you made up, or did someone else?

That's A LOT of runs to not fall within your "just a good normal run" range, wouldn't you say?
In fact, it looks like only 1 of my >110mph runs meet that criteria.

would be capable of. i run 1.84's with a stage 2+ allroad(stock clutch) and the power to weight ratio of a stock s4(aprox). 1.65 could drop you et 2 tenths. i don't recall what the temp was on your 12.3 run but if you look at the slip of the 11.5 listed on biturbo board it was 32 degrees and that will make a big difference too. and finallying you said you are making more hp then when you ran 12.3.link following is an engineer from honeywell discussing drag racing. about half way down page is part about ratio<ul><li><a href="http://www.turbobricks.org/resources.php?content=quartermiledyno">http://www.turbobricks.org/resources.php?content=quartermiledyno</a</li></ul>

Let me guess, the tracks are uphill in both directions also?

After making those 3 passes last week (<a href="https://forums.audiworld.com/s4/msgs/1783153.phtml">post here</a>), I logged as I left the strip on my way home. Here are 2 pulls that I did, one in 3rd gear and one in 4th gear. This is just running stock N75. Anyway, just wanted to show that it was indeed running *only* 20psi:

Also, here's one of those vs requested:
