HPD adjustments make no sense, more weight but bigger air restrictor (to bring it up to Oak level??) and more fuel.
Pretty sure that bopped +1,6mm = 29,5mm restrictor size is the biggest Corvette has ever had in GT2/GTE. Less weight on top of that - plus Ferrari begged pack - so surely they'll be winning 'miraculously' again |

The increase weight will make the P2 tires heat up more faster.
Those poor Mazda still haven't got a BoP break. That's so unfair. |

That 90 lb addition doesn't make much sense, but it's The New IMSA after all.

51 cars isn't too bad a turnout! I'll be there from Wednesday night to Sunday morning, so it's the full medley of races for me. I'm looking forward to meeting a few Tenthers down there!

I don't think Mazda is making full use of the breaks they already have so it doesn't really matter what the rules say on paper. They could give them a 500KG min. with as much boost as they could make but I think they would still run what they've been running. |

I think that IMSA is at the phase where they're like, "Screw it! Let's experiment with the P2s!

However, Audi spend and invest more money into their race program than Mazda, Audi race in LMP1 vs LMP2, and rules are more lienent in LMP1 than LMP2, and Audi have a full-bore bespoke racing engine in all their diesel LMP1 cars, while Mazda has a stock block engine which almost 75% of the parts are shared with the road car diesel engine. |

Yes a tiny inline 4 banger stock block engine grafted onto a Lola chassis.
I just want them to be sped up a little bit just to be out of the other classes hair. |

That's not gonna happen as long as the stock parts can't handle the power boost. Granted, they haven't had very many engine issues aside from fluid leaks (mostly they've had electronic issues with the gearshift mechanism), but that engine is for sure gravely down on power.
There were already worries about the HPD stock block turbo 6s maybe not being able to handle much in the way of air-restrictor increases. What really screws Mazda/Speedsource there is that the Mazda engine is an inline 4 instead of a V engine, and it's a diesel where the cylinder stresses are as high as anything that Audi or Peugeot have ever seen with their diesel engines. Shades of the old AER P07 inline 4 from the old Lola MG LMP675 cars--you have to run a lot of boost to get that power, and that'll cause an engine to destroy itself if you're not careful. |

BOP changes for COTA!
HPD/Ligier HPD P2 40kg more weight 900kg to 940kg. More horsepower with a larger air restrictor. Larger fuel tank. DP smaller fuel tank. |

From what I have heard, the Mazdas have a huge issue with cooling--the engine is working so hard in so tight a space, and trying to make more power than it did in the Mazda6 ... and until they get the motor to work, they can't even begin working on the chassis.

Another deal is that Audi and Peugeot designed their cars around and with the use of a diesel engine in mind.
The Mazda chassis, in spite of it's branding, is just basically an off the shelf Lola customer car design, designed around using 4 cylinder gasoline engines or V8 NA stock block engines. |

Jeez why even bother watching now,they even managed to hack up GTLM.
They did really good at letting corvette get a points lead,rolling them back so other cars win and the points battle becomes tight.all just to let the corvettes at it again to win the championship,it's awesome we all called it when Imsa changed it to four bops a year.what a joke,I wish I could say Gtd was better but even that's a bop'd mess. I wish I could say the P2 change is good but I doubt it,it's a little to late to remove fuel capacity from dp's .thats something that should have been changed races ago, I think at this point esm already has their mind made up and oak isn't to far behind. |

If I were Porsche, that third 991 would be Montoya-ing the Corvettes at every chance.

Have Oak or ESM (or their drivers) sounded off on these changes yet? I'd be interested to hear their take on things. |

Increased weight will not help the P2 cars. If adding weight could make the car faster, then I'm sure the teams would have added weight a Loooong time ago, unless there is a "maximum weight" limit.
The restrictor increase is relatively small, so I think that this adjustment is really going to hurt P2 teams. |

The fuel tank tweaking should have more direct effect than the weight and restrictor changes.
I'd like to know the baseline values of ACO-spec Oak coupes to see how much bopped those IMSA values are on that car. But as we've discussed recently ACO hasn't updated those sheets to us for ages |
