Me! And all day Friday too. The weather forecast says High of 90 so I'm looking forward to it being a couple degrees cooler than where I'm at now.

Spotter Guide is online complete with the return of the Poster style guide, albeit over two sheets. Same plan for PLM.

NISMO have also stepped onboard for the WEC Spotter Guide, so thats also released.

Is it just me or does the engine sound better in the Ligier over the open-top HPD? Maybe it has a different exhaust, or just has a lack of wind-noise, but it sounds pretty good to me.

Yep. Tested back on the 4th with Gabby and Katherine. Tried a bunch on new areo bits. Car should look a bit different at Petit.

Fall Line withdrew their car. One of the drivers was injured in a road accident, and I guess it's his money paying for everything, so they're out.

Yup, Charlie Putman.

From Fall Line Motorsports' fb page:

Our good friend Charlie Putman was involved in a four-wheeler accident on Monday and suffered serious injuries. He is recovering in the hospital in Wyoming but will not be driving at COTA. The team had decided to pull the @Audi GTD entry for this event. We are all keeping the Putmans in our thoughts and prayers and wish Charlie a speedy recovery!

TUDOR Guide has been updated to reflect #87 inclusion and the renumbering of the Turner Motorspots Z4.

Sad news about Charlie, That car is still included on the guide

Richard Lietz will not be racing this weekend.

chernaudi · 18 Sep 2014, 21:11 (Ref:3454815)

In WEC practice, ESM ran a 1:58.1 with an ACO spec car (less power, less weight, Dunlop tires). I wonder what'll happen with the IMSA spec car later today (more power, more weight, Conti/Hoosier tires).

chernaudi · 18 Sep 2014, 21:12 (Ref:3454816)

Edit--wrong topic.

Rcz · 18 Sep 2014, 21:22 (Ref:3454822)

Out of all the tracks that IMSA goes to.

This track is the best place for the P2s.

Purist · 18 Sep 2014, 21:29 (Ref:3454825)

How do you come to that conclusion?

The three main flat-out runs are all preceded by slow-speed corners, which will favor the torque of the DPs. This track doesn't have many long-duration, high-speed corners, like Mosport has, and the main one, that mirrored copy of Turn 8 from Istanbul, has that series of kink-apexes to it, which makes side-by-side running through it much more difficult.

Yes, the P2s will enjoy the esses, but the DPs will be in front by that point on the opening lap, and the P2s won't be able to get back by them through there, probably.

I thought Laguna Seca was.

I think the extra 40kg will make the P2's a bit slower through the bends. I could see a few "moments" happening during the race for the P2 boys. Especially the ESM crew because they will be running machinery they are used to. The Oak guys will be running a new package so they are feeling it out for the first time anyways.

Purist · 18 Sep 2014, 23:00 (Ref:3454838)

Well, "feeling it out" has Alex Brundle ahead of Johannes van Overbeek, but even Alex is 1.1-sec off of the mark set by Richard Westbrook.

EDIT: Now Johannes has gone just a tad quicker than Alex, but is still a little more than a second off of the leading time.

Purist · 18 Sep 2014, 23:37 (Ref:3454841)

So, the first session ends with SoD up front in DP, ESM leading P2, the Porsche factory squad leading GTLM, and the TRG Aston ahead in GTD.

chernaudi · 18 Sep 2014, 23:42 (Ref:3454842)

How did the times compare? ESM ran a 1:58.1 in the first WEC session.

Even Westbrook's time was over 2 seconds slower than the leading WEC LMP2 time. So that shows how much off the Continental tires are vs the Dunlops in the WEC.

TRspitfirefan · 18 Sep 2014, 23:59 (Ref:3454846)

First Practice times.

IMSA "Prototype"
Spirit of Daytuna #90, 2:00.306
ESM #2, 2:01.338 sixth in class.
Oak #42 , 2:01.406. seventh in class

IMSA GTLM
Porsche #910, 2:04.844 First in class.

For comparison, here's the WEC times.
P1 #1 Audi, 1:51. 136

P2 #30 ESM , 1:58.111

GTE #97 Aston , 2:06.399

It is interesting that the ALMS GT class times are significantly quicker than their WEC counterparts.
Were the track conditions more favorable during the IMSA FP1 session?

**joeb** · 19 Sep 2014, 00:43 (Ref:3454856)

There is slightly different bop between the wec and IMSA gt classes. I'm not sure what the difference is between the Porsches though

Lagunaseca_4life · 19 Sep 2014, 06:18 (Ref:3454910)

B . O . P!

TF110 · 19 Sep 2014, 07:47 (Ref:3454929)

Those Porsche's are going to be tough to beat. Viper up next it seems.

justracing · 19 Sep 2014, 08:12 (Ref:3454938)

Just woken up to the fact that this event is on this weekend, is there live streaming somewhere?
