Qualifying Results:
http://results.imsa.com/Results/19_2...20-%20GTLM.PDF 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. |

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.

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?

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

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 |

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 |

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.

Thanks, I think Victor just let the cat out of the bag as to why the times were so much faster.

Another piece of data is the Mazda. Recall in 2014, their pace was 1 min 49.7. They have improved by 16 seconds a lap from when they debuted to today. |

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 |
