Really impressed to see the track record broken. The LMP2 cars have pretty good pace as well. 1:35.9 is not bad given how they have been restricted. If any of the P2 teams have a clean run they could easily contend for a podium.

Qualifying?! I guess I've missed something from living under a big rock or just plain forgot...

FormulaFox is heading for a stewards' enquiry!
If I were IMSA, I would be VERY hesitant to make any BoP changes after this weekend. If I had to do something, I would give the Nissans an ever-so-slight increase in power, but even that I doubt is needed as I think their relative lack of performance is more due to unfamiliarity with the car than any lacking capabilities with the car itself - they did get a 34.9 as their best time, after all.

I had to look that up too. It is "qualifying" for pit stall position.

and yes gtlm is closer than siamese twins

From the S365 daytona notebook, the times put in during the Roar don't count. It is not considered an official session, even thought it is mandatory? WTF?

***While Oliver Jarvis recorded a 1:33.398 lap time in his Multimatic-built prototype to lead a Team Joest 1-2 sweep in Roar 24 qualifying for garage and pit lane spaces, it did not go down as an official lap record despite being quicker than PJ Jones’ 1:33.875 lap set in the 1993 Rolex 24 that still stands as the official record.

***Since its introduction last year, IMSA has not considered Roar 24 qualifying to be an official session.

It's only officially mandatory, not officially a session sir. Please keep up with the rules, they aren't hard but you'll have to read IMSA's mind to know what the rule is today

Wow, notice that Mazda is not mentioned?
It is Multimatic and Tean Joest. In an environment that wants the engine manufacturer before the chassis builder that seems weird to me. Is there not mention anywhere of one Japanese four cylinder beating another Japanese four banger's record?

Not so much a battle with rival Toyota but more a tribute to Gurney and AAR (but notice that Doolan never mentions Mazda's rival by name):

http://www.dailysportscar.com/2019/0...wcetJP1jGf_M4Y

With the significance of their 50th anniversary I firmly believe IMSA will allow their DPi entrants to go after the official lap record during the Rolex. I'm sure Acura is highly motivated as well. Let's hope the weather gods will play their part!

I read Mazda/Doonan think that the pole for the race will be faster and they aren't worried about bop. They might be pegged back but probably not by much if they are at all. I hope they'll wait for the actual qualifying times and see what everyone really has. I had a good feeling Mazda made strides, looks like I was right. Hopefully they did the same thing for their reliability.

Speeds so far are impressive. Thinking it will be faster a few weeks.

DPIs are now the fastest cars at Daytona ever
GTLM is close to where Grand Am era Daytona Prototypes were at
GTD is about where GTLM was in 2014

2018 Roar Qualifying - Fastest LMP2 - 1:37.274 (JCDC)
2019 Roar Qualifying - Fastest LMP2 - 1:35.930 (PR1)

2 seconds faster for the LMP2s. PR1 were half a second off the 2018 LMP2 fastest time, so maybe about 2.5 seconds.

Consider also that lmp2 lost 50hp at least compared to 2018 season; no doubt lmp2 could mark 1.34 with the 2017-2018 same power.

Don't know if DPi got aero updates during the winter, they got some extra power for sure, but michelin contribution is more than 3 seconds if pole will be in 1.32

I don't know what the weather was last year, but the weather this Roar was about perfect for fast laps.

2 seconds improvement is really good for the P2's given they have less power this year.

One thing that Bourdais said when talking to Marshall Pruett on camera during the night sessions was - last year, GTLM running on Michelin and everyone else running on Contis meant the track wasn't really getting rubbered in and the only influence on speeds were actual weather conditions, the track itself wasn't evolving; now that everyone is on the same tires, they are noticing proper track evolution and the racing line getting faster.

Finally! The continental tires were decent for what they were but they are not in the same league as Michelin. It's about time imsa got all the classes on actual good rubber so they can get on with finding time in the track like most other series.

well.... useless to say that when you're the slowest one, you just can get better, but need to remind that in 2014, mazda used 2 modified lola b12/80 (by far the worst available lmp2 chassi) powered by a silly diesel engine that barely had 400hp...


Mazda improved a lot from last 2 seasons where they had a crap aero/chassis with less downforce than anyone else and much more drag because of that lmp3style designed windscreen. Not to mention AER reliability issues.


This year, it seems mazda, multimatic and joest guys found a way to finally improve aero efficiency of the car; it developes more downforce for sure and despite that windscreen marked 195mph. Surely -30kg, extra boost and revlimit set to 9300rpm helped a lot. Now just need to see if AER did finally their homework

I don't think we can compare that Mazda to this Mazda DPi...plus at the 2014 Roar that Mazda ran a 1:39.828
