Nice! At a DA of 9500ft that corrects out to a 12.38 at 113 - that is smoking! Any trouble launching/getting traction?

And team AR Design and team HPF....and soon to be team Wavetrac

Yeah I was happy with my times all things considering. People were complaining about the hot & humid night. I know I can be faster though. Traction was decent, I would say that wasn't my issue last night. My best 60' was 2.04s, which is up there with my best on the setup I have right now. My IAT's were around 130°F all night, not great, though they would come down pretty quick after the run. I ran stage2+FMIC Aggressive last night, with 3 gal. of 104oct and 6 or so gal of 91 oct. Ran great, no codes, no hiccups, and my logs were decent looking, peaking out about 17.3psi.

My best time I posted above was the 3rd to last run, I aired down the rear tires to 25psi after that, but it made getting traction much worse for me and I only got a 2.3 60' on the last two. So I won't be doing that again on these tires.

BTW, nice meeting you Tyler, good times, too bad no one else came out.

16M4 · 06-14-2012, 10:27 AM

Wow great time, Craig. I need to address the issues my car has been having so I can be that quick.

What was your best ET and MPH with full mods (I know you never ran with the Wavetrac)?

Now Cobb just needs a race gas map.

Here are my logs for anyone who cares. No RPM, but you don't really need it. They look pretty good IMO, but can really tell the turbos have a hard time keeping up...look at that gap between Actual vs. Requested load. These are my logs from the last two runs of the night, when I was having traction issues. Boost is tapering a bit more than needed though, and King mode and I saw that on my slips because I was dropping off between the 1/8 mile and the 1/4 mile

richpike · 06-14-2012, 01:11 PM

Is the delta between actual and requested due to our thin air? The turbos just can't spin fast enough?

-Rich

raceyBMW · 06-14-2012, 02:13 PM

Pretty sure that's what's going on there yeah...but I am not sure why I am getting so much boost taper.

Bimmer This · 06-14-2012, 05:39 PM

Mine was a 12.92 @ 111mph on all season tires.

raceyBMW · 06-14-2012, 05:43 PM

That's awesome! Did you ever datalog?

That would mean our turbos are pretty much maxed out around 20psi at sea level? I think 5,800ft is around 11.8psi - sea level is 14.7psi. Add that 3psi back in and they are at the top end of their ability?

King mode · 06-14-2012, 06:48 PM

The weird thing was that at the 1/8, i would be at 81-82mph and your would be at 85-86mph but at the 1/4, we would always be 2mph apart. you being RWD, you would think the difference would be greater, not much less?

Is it true that xi's become 100% RWD after 75mph (rumor ive heard)? if so, that could be a reason.

I WANT A RACE GAS MAP!!! once that happens, we will see much better times.

King mode · 06-14-2012, 06:50 PM

Also, I had 2 or 3 1.97 60's and the rest were 2.0XX all night. Homefully it was just the heavy air slowing my launch's?

Will a race map help much if our thin air is limiting us to 17psi? Maybe on the boost tapering so fast?

Going from sport map (91 octane) to aggressive (93octane) I picked up 5mph. So a tune for race gas will deff help. Keep in mind, the boost was the same for sport and aggressive. It's all about timing.

forza1976 · 06-15-2012, 12:54 PM

wow, 5mph...

Ahh - makes sense. Very cool!

Carl Morris · 06-15-2012, 05:57 PM

Just as another data point I tried Stage 1 aggressive and only saw about a 4mph total increase over stock. Not sure why I didn't get nearly as much from it as King mode.
