Rolex fastest lap:

#66 - 1:44.086
#4 - 1:44.437
#3 - 1:44.517

Other than #3 which went from winning the pole by 2/100 to being 1/2 second slower per lap in race trim --
all the other cars/times seem consistent.

The only reason the vettes were fast in qualifying is because we were drafting each other, and we reached out fastest times on our optimal laps when the tires were up to temp and pressures and were not greasy yet around laps 3-6 or their abouts. After that the tires get greasy and lap times fall off.
The 2nd place ford was able to run basically the same time in qualifying as pole but did so on lap 12 or 13 when tires were past their max grip, and the ford was all by himself not drafting anyone.... that right there told us that it was going to be a long race.

About your fastest lap time comparisons.... its kind of misleading... yes although the Ferrari was faster than the fords by less than a 10th of a second, the Ferrari was pushing at 100% and I do not think the fords were, I think they could have done a 1:43.xxx any time they wanted to but did not need to cuz they had control of the race.
I think this because one of the fords (cant remember number) ran its 1:44.0 on lap 6 of the race! That shouldn't happen because as the track rubbers up the times always come down... Fastest times will usually come sometime on sunday as it did for every other GTLM car.....
Another reason is that the fords were basically running within 2-4 secs (sometimes less) of each other at the front the entire race.... well when they would get split up due to slower gtd traffic and be 6-8 seconds apart..... the trailing Ford after a lap or 2 would be right back up to the 2-4 second gap they were told to maintain.... and the trailing ford could do this at will by running a little harder (97%) for a lap or 2 to catch back up to the sister car and then settle back into cruise mode......

There was just no need for ford to show their true pace and risk BOP penalties..... I think if one of the ford had minor problems and had to fight back up threw the field, we would have seen faster than 1:44 times from Ford.

Thanks for the insight --

On the subject of qualifying -- none of the cars ran more than 9 laps.
While #3 set his fast time on lap 4,
everyone else set their fast times on lap 5 (66 & 911), lap 6 (24, 25, 912), lap 7 (4 & 67), and lap 8 (62).

Apparently, it was fine when it was tested before the race when IMSA tested it.

Marshall Pruett's analysis of the #29's 5 minute penalty. Goes into a lot of detail, but short version: #29's rig was completely legal, they just got hit because they did a better job than the other GTD competitors.

Prior to all of this IMSA on-board telemetry business, you just did some cheatin' to get that extra speed. Time-honored, especially in NASCAR. All Corvette Racing needed was a tenth or two per lap--IMSA would have hardly noticed.

Just out of curiosity, which car has the bigger fuel tank?

You are correct about the lap numbers..... I have no idea how I came up with 12..... I was listening to quali live in the car while still traveling to daytona from Wisconsin.... I must have misunderstood the laps while i was focused on traffic haha. :thumbs:

Le Mans Entry List Posted.

As has been the case, the boys in yellow will be #63 and #64.

Some notes:

A large 17 car GTE Pro class:

-Risi is not bringing their Ferrari and will not be in GTE Pro. They will be running Ben Keatings GTE Am Ferrari.
-Ford again is entering their 4 cars
-Porsche is following suit and running 4 cars
-AF Corse is running 3 Ferraris
-Finally get the BMWs in their new car runing Le Mans with 2 cars
-Aston has 2 of their new Turbo V8 Vantages


No other Corvettes as Labre has moved to LMP2 with a Ligier. IMSA's
IMSA's JDC-Miller team declined their automatic invite.

Should be a good one, and with 17 cars, winning will be well deserved (as long as there is some reasonably decent BoP)

sunsalem 02-09-2018 08:30 PM

We don't need no stinkin' 4 cars to win Le Mans.

​​​I just looked at the list and only have 15 cars and no vettes. I see you say they are listed I have been going nuts trying to find out if they were going to have a team there. JDC Miller won’t be there? I was on motor sports. Com and they say 17 cars but don’t have a corvette listed and as I’ve already said they only show 15 cars. I didn’t understand why risi wasn’t listed but see you say they are in gte am. Please if you can, post what team will be there with a vette I am so confused

Regarding Risi, they only race in the States.
AF Corse handles the European stuff.


As far as Mr. Keating and his MB GT3 goes, Mercedes does not allow their cars to race Le Mans.
It has to do with historic tragedies involving the brand.

Uhhhh....

Risi has run Le Mans a whole bunch of times, and won the class as Le Mans 3 times. They ran last year. They are not running this year as they are cutting way back on their GTLM/GTE Pro program.

Keating's GT3 Mercedes isn't running at Le Mans, because they don't run GT3 cars at Le Mans. Mercedes simply does not manufacture a car eligible for Le Mans. It is true they left Le Mans due to incidents and returned and left again in the 90s after an incident, but at the moment, they don't have a car eligible. They've stated their big factory efforts in racing are for F1 and now Formula E. They are even pulling out of DTM. And then obviously happy to sell customer GT3 and GT4 cars. In fact, GT3 Mercedeses run in the Le Mans Cup, and have/will run at Le Mans as a supporting race to the 24 hours of Le Mans. They will be on the same track the same week.

I was speaking about THIS year.

They don't have a car in ANY class for this year's race, or last year's race or the year before or the year before...all the way back to 1999 with their flying carpet: the CLR.

Sebring test is next week (optional unlike the Rolex Roar). Interestingly enough according to the entry list, Corvette is only bringing the #4 car and drivers and not bringing the #3. Not a big deal as other teams have taken similar approaches in the past, it's just unusual as Corvette generally runs as much as they can wherever they can....

35 total test entries, 8 in GTLM (including the #4).

z28lt1 02-15-2018 10:38 AM

Sebring Test BoP is out.

In GTLM, Boost changes to BMW, and fuel changes for BMW (more), Porsche (more) and Ford (less). No other GTLM power/weight changes. Again, going to high downforce configurations and slower tracks will likely even things up from Daytona.

In GTD, seems like IMSA is really struggling to get to the MB-AMG correct. This round they get a smaller restrictor, and increased minimum ride height, but get (a whopping) 5kg weight reduction. Interesting changes.

It IS interesting.:yesnod:
I would love to know exactly how they come up with these adjustments...must be computer analysis of some kind.
