That's surprising, I'd assume Michelin had an exclusive agreement with IMSA restricting teams to only their tires at official events.

Sounds like quite a few former ESM folks have been contracted by Core:

Let's hope Core's campaign goes beyond expectations (again!) so they'll consider running the second car as well!

I would say no because we have an abundance of white already between BMW, Porsche, and now Ford.

The Contis are probably just travel tires.

is available any live timing?

thanks sir, BTW why red flag?




faster than last year pole already

I can already see IMSA returning the P2's back to full WEC/ACO spec as the current P2 leader is already 6 seconds slower than the DPi pace setter and only 3 seconds ahead of the GTLM leader. Still early but think they went too far with the P2 restrictions.

[canaglia]

Expect GTE pole high 1.41 - low 1.42


LMP2 should be at least 1.38 to be comfortably ahead gte

[Damian Baldi]

Straight line speed seems still low. Last year I think it was 196mph and over 200mph in 2016 before the restrictions and with 6.2 engine on the Cadillac.

It's too early, Juncos was doing 1.36.0 on the Michelin test.

[canaglia]

Thought 1.34 dpi pole was too optimistic, maybe could be even faster

[Damian Baldi]

The #55 is 3mph faster than the #77, I have read that the #55 have the last updates and the 77 not.

EDIT: now the #77 is the fastest with 193.4

where are you checking top speeds?

You have to click on "PITS" on the top right and it change to "TS". It works with "Team/Cars", "Lap/Time", "Gap/Int" too.

[canaglia]

thanks sir again.
As usual mazda's have always had great top speed during test; anyway even if dpi got some extra hp, very likely TS will remain the same of last year. Guess lmp2 style bodywork generates too much drag however, even if in semi-LD setting.



Recall old days when Riley and Corvette dp in 2012-2013 had a <190-195mph comparable top speed despite being heavier and powered by only 510-520hp; guess dp old bodywork generated close to 0 downforce but close to 0 drag as well.

The timing screen feels more interactive, but is there an option to display all these things at once rather than have to cycle through? I feel like that was the case previously.

[Maelochs]

IMSA T&S working for me too.

Tomorrow there is supposed to be live video.

Would be neat if that was the case. I figured one of these days the GTLM class would get fast enough to match the Grand Am era Daytona Prototype lap times.

how to make a good impression to your employer son

Most people would just go out and win a world championship.



Who is this clown?

[kvenom]

Mazda have also added personnel from the Ford WEC team for support on dates that don't clash. They must be paying Multimatic and Joest a large amount of money.

Actually I did the same, and was a bit concerned by gte potential/latent performances.

2013 was grand-am and 2012-2013 DP3 final season.
Riley ford/bmw and corvette DP used 5L V8 with a power about 510-520hp, were 1030-1050kg heavy and had a really poor aero, a crap aero also for that time. Had crap continental as well.
Despite a not so big power, dp3 were able to reach >190mph, at the end recall 2013 pole was 1.40.5

2016-2018 gte have basically the same power, all but porsche have more torque too + a much more advanced aero and confidential state of art michelin tires. Unfortunately are also 200kg heavier.
Surely this year gte pole will be in 1.42 range

Quite disappointed considering that nowadays gte are faster than 2006-2008 GT1 that were 100kg lighter and had about 80hp more. At the end guess that huge extra weight and huge drag simply kills acceleration and top speed making gte slower than old dp3 at daytona because of that.

(dP3, even if named prototypes were just a carbon bodywork mounted on a caveman steel frametube chassis...)

[canaglia]

BTW WTR just hit 192mph
getting closer to 310km/h

[canaglia]

something really wierd is happening in gtd... amg gt3 used to be the guineapig among gt3, several km/h top speed slower than any other gt3, in IMSA and BES as well. So far marked top speed in his class.
Mazda's are quite competitive in all sectors, hard to find out if they're pushing too hard compared to others

[TF110]

Don't IMSA mandate set wing angles in DPi and add gurney flaps? If so, they probably slap it up pretty high so as to limit the top speeds. Mazda's pace looks encouraging imo.
