Apparently IMSA disagreed with some people here who said the balance between P2 cars and DPi cars was fine.

Long Beach is not even a good type of track for their car. The Caddy's will be better because of the slow corners and lots of stop/start where acceleration will be key. Their big engine is at home in Long Beach. Maybe we'll be surprised but it looks like a win for one of the Caddy's is a pretty safe bet imo.

I agree about the Mazda, even with 7 liters less fuel it is still a 1 stop race. So far now, that doesn't hurt them.

But this also brings up my biggest pet peeve about imsa Bop. I can handle the power and aerodynamic bop but they should at least give everyone the same amount of fuel and let the individual teams and manufacturers decide what engine is going to be best.

That's what like, one lap of fuel taken away from the Mazdas compared to other DPi? I'm not going to go look through the lap charts but seems believable. The Mazda is also still the lightest car in the field, I wonder if they were even actually able to use a 15 kilo weight break properly.

They'll average around the 3L lap mark so it's closer to 2 if not 3 laps. can be quite substantial.

Anyway the average lap time facts from sebring were pretty day and night on the bop needing work and they would have crunched the same numbers to get the same conclusion.

Also I've heard the Gibson struggles when air temps begin to rise above 25C regarding torque loss so worth keeping an eye on the temps for the next round.

...But that would favor the Cadillacs. Last year when the Cadillac was the best a bunch of people just complained about it and threw up the usual "O YA OBVIOSLEY MERICAN MANOFACTORUR IZ FAVORD BY NASCAR" type comments and suggested GM bribes the series and so on. Oh, and the guy that was suggesting the old pushrod V8 should be banned.

I don't think GM needs to bribe the series when they're effectively being paid to participate.

Anybody pay attention to the WEC prologue lap times. I think the DPI cars pace would at the very least match the non hybrid LMP1 cars.

The current DPi? No way! They couldn't match Rebellion R-One at COTA and the current crop of private LMP1 are going around Paul Ricard faster than the R18 in 2016:

Not even close, they may be slightly faster than the P2 cars but there is still a large gap to the P1s.

I agree 100%. They build a more efficient machine but don't get to use that efficiency even though endurance racing is about being efficient. The Caddy gets to use its torque and power but Mazda is not getting to use its efficiency. IMO

I just checked the Mariantic site and was reminded of the BAR 1 Riley that was at Daytona but missed Sebring. What are the odds we see that for the rest of the season? I was going to ask about the Transformers car as well, but....

Do we expect any additional P cars for any of the races this season?

Someone in the Racer comments section is claiming that employees have not been paid for their work at Daytona.

His source is himself having not been paid, but he refuses to respond to any inquiries on the matter, so take it as you will.

Unless I'm misreading the changes...

The Cadillac has the smallest fuel tank by 7 liters, so it's the one that isn't getting to use its efficiency.

Meanwhile, the Mazda just got cut back from the tied largest fuel tank, so really it was believed by the series to be one of the least efficient. Post-change is the same size as the Acura's tank, which is the second smallest.

SoD: >50%
BAR1: <25%
Transformers: <0%

I think United is supposed to do the NAEC with a single car, otherwise I don't see any additional prototype entries, especially not with the Euro season about to be underway.

OK, thanks. I stand corrected.

Reminds me a situation I once ran into. I bought a pickup truck and purposely got an inline 6 to get better fuel mileage. Worked great on flat land but once we hit the mountains, that efficiency went out the window. Replaced the inline 6 with a 350ci V8 and got better mileage overall.

“To be frank about it, part of the reason we aren’t continuing, is because there’s a performance gap too, between DPi and P2s. From the BoP point of view, IMSA is making progress, going back from when it was P2s and DPs, progress has come on quicker this time.

“But from the nature of the two cars, even with the same chassis, it’s more than just the same cars with new aero and a new engine. “The reality with it is that it’s not just the engine, it’s the suspension package you can develop, so when you look at, for us, our ORECA 07 compared to the Acura Penske cars, speaking to the drivers they were saying that at Sebring the bumpiness was far less than for the P2s.

“At Daytona, the DPis can come out of corners better, they’re more complient. Even though we could make the same lap times, with good drivers, for them to make the time it they had to be on the edge. But the DPis can consistently get that lap time running at 95%. It puts us at more risk.

“It’s always hard to see unless you see really in depth. The only way to make it truly better I think, is allowing us open development on the global P2 package.”
I reckon Jackie should buy a Ginetta if he wants that, DPi is clearly not the formula for him.

That would mean that the ACO would have to approve the changes. But that's been kinda a beef with IMSA allowing more open development of DPI versions of the cars vs ACO spec LMP2s, while stating that LMP2 was the performance bar that would be adjusted to.

Again, LMP1 and DPI, if IMSA and the ACO can agree on basic regs, should be combined in concept and LMP2 left as is.

I had the opinion at the time that the people who enjoy IMSA's current way of doing things better enjoy Daytona this year because it was never going to be that big again, and it's certainly being borne out. I'm kind of numb to it now but it's pretty lame to have an event with that much potential international importance still being crippled by provincialism despite having a common "platform".

HART Acura won't make it to Mid Ohio. I hope that they will focus on getting funding for Lime Rock and VIR at this point. Not even Watkins Glen if their resources are limited. I think the all GT races would be a great target for those with non full season aspirations.

The smaller GTD grids won't be a big deal at the full combined class races. But it will be noticeable if we can't get GTD to 12-15 cars at the all GT races.

This was exactly why some teams wanted the P2 cars to be a separate class with an Am requirement. Perhaps if DPi continues to be strong this will happen.
