I don't think that solves anything for the international teams. Ride buyers can always buy locally, the guest appearances on the other hand are well funded teams that only run Ams out of obligation in Europe and are hunting for overall wins.

If DPi were equal to lmp1-private, teams like this and Rebellion and Kolles and those Manor squads could jump in and compete. Lmp2 doesn't have to be the top class's speed. Next year with Michelin on board I expect the lap times to drop even more and being honest, DPi is being held back to no avail because they're still faster than lmp2 by some margin.

That's a extremely large "if" that just isn't happening with the current generation of cars (even if it was plausible on a performance level there's no way anyone on the IMSA side would agree to having their cars compete against such technically different cars). Michelin makes no difference, those tires will still be slower than what's on a WEC car in either prototype class and won't change the performance relative to P2.

The stuff Cheng is talking about isn't any kind of fundamental chassis advantage either, it's just being able to optimize the car for local conditions. There's no design magic to the Acuras riding better at Sebring, it's Penske's shock program finding a better set up than ORECA made available with the homologated parts. The Cadillac is basically running the Dallara high downforce kit because they don't have to worry about Le Mans and can BoP away any speed deficit at Daytona and Road America.

I don't wanna go off topic anymore, so this is my last comment on it. In lmp1 there's freedom to change things like the suspension. That is a precise issue his team has when facing DPi. DPi could be at or near lmp1 speed with a little tinkering. Lower weight, higher power. Maybe cars like the ESM Ligier is a little heavier. There's a solution in buying a new chassis, maybe using a ByKolles Nismo? Maybe Mazda has engine power issues. There's a new AER engine running in the lmp1 SMP Dallara's (who make Cadillac's chassis). I think going forward in the future they need to target lmp1 or whatever the class's name is in DPi. Then lower funded teams can win their own class with AM drivers (lmp2). It was already suggested, maybe they should take a look at it again. Imo, they won't be equal even with excessive bop. They might take a lucky win or two, but 9 times out of 10 it'll be a DPi lockout.

As long as the #86 Acura NSX runs well and stays in title contention, there will be funding for the team. First bad run, then it might end.

BAR1. That may be the end of the Riley Multimatic LMP2 story. Only chassis now in use are the Mazda ones.

Is that true? I ask because the minimum weight is 930kg but the Mazda was just at 915kg a race ago and the Oreca chassis (Acura) is very much ballasted to meet the minimum weight. That's why it worked out to use it for Rebellion's lmp1. Maybe the ESM Ligier is a bit heavy because of Nissan's engine but I have a hard time believing they're struggling to meet 930kg. It's more likely ballast is added by bop (especially to the Caddy) to slow them. Isn't their new engine is lighter this year?

Sad for the Riley, but they're outclassed. The car is slow, even after the rework. I think it's all down to the Mazda's bop and the Joest team running them that they're on pace with that chassis.

I'm with you there, I'd want to see something that shows they are all that much heavier. Seems like the tables didn't really show that with their weight BOP.

The ORECA is, the Acura is by all indications not or else there should be no reason to be running overweight and stressing the car harder. Turns out that a beefed up Accord engine with twin turbochargers and a subframe is just a bit heavier than a proper racing V8.

Mazda doesn't have a weight issue because it isn't a stock block, but they also can't turn the power up any higher anyways.

Putting the car up for sale doesn't exclude future outings (although rather unlikely). It'll depend on customers ponying up the rental fees. No change from before for this team.

No, he's saying exactly what Coach EP said as well, BAR1 has always raced what others, the paying clients, wanted. This client no longer wanted to run the Riley and frankly a dumb choice before the season. I think he also thought they'd get an Am award going. But the Riley is a dog and the Am trophy isn't happening so the owner of the chassis, not BAR1, are selling it. If another driver(s) approached with funds and a chassis they'd be right back in the series.

I know you're saying they're running overweight, but where is that stated officially? Purposely handicapping yourself by running a super heavy engine doesn't seem like something Penske or Honda/Acura would do. This engine isn't 'new' either so I'd think they have some idea of where they are going to be in terms of (added) weight with it vs the Gibson.

Anyone starting to think it's a good idea for IMSA to eventually split DPI and LMP2 given that DPIs are being slowed for the fourth time in as many races with BOP?

IMO, big problem is that DPIs are allowed development, LMP2s aren't due to ACO homologation. So BOP automatically becomes a moving target every race.

I'd be ok with it if it meant the dpi were allowed to go as fast as they could. But you'd jeed more than 3-4 full season entrants in p2. Maybe keep it like this at least one more year after this one so p2 teams get a few years of use, then fold p2 into p3 as a second prototype class, with pro-am requirements?

Or just allow development or improvements to the p2s in imsa, to keep up with the dpi rather than slowing down some pretty cool cars.

Can't really allow development of LMP2s due to agreement with the ACO and the ACO's own homologation of LMP2s.

They can't, they have an agreement with the ACO for the use of the P2 cars.
