Does anyone know if the IMSA race feed will be viewable in the UK, i couldn`t connect with the qualifying, had to make do with the commentary and timing.

Yes, all IMSA races are streamed live outside the US on IMSA.tv. If it doesn't work, try a different browser. It works for me on Chrome.

[GriffM3]

Anyone know if their will be onboard feed for this years race?

[joeb]

Not much in the way of BOP adjustments post Roar

GT3 BMW has a different fuel tank size. that is all i can tell.

Odds on at least one Porsche magically gaining 1.5 seconds? Wonder if the telemetry showed they weren't using every rev or what IMSA saw? They generally aren't terrible with it outside of the occasional slight but almost 3 seconds as a group seems like something is off

[joeb]

These aren't the type of notes we usually get from the paddock, but Graham has some good gossip:

https://www.dailysportscar.com/2023/...ock-notes.html

There are several LMP2 Oreca 07s here that are with at least their second owners. At least one is understood to have been received by its new team with several aspects of the car understood to have been significantly out of compliance with the regulations, the presumption being that its previous owners raced the car in that state!

[Adam43]

You’d think they’d return it to a compliant state before selling. Not so much to cover anything up, but more so people get what they paid for!

[broadrun96]

Makes you wonder about both the team and the series. And what was out of compliance, cause we know holes in the bodywork to slam the starter with a hammer are NOT ok

Is this in reference to the Proton car? I vaguely remember reading something about it but cannot recall where & when.

I don't know which team it could be.


Endurance Info has some good facts and figures about the race:

And I added the Andy Blackmore Guide to the opening post.

Thanks Joeb!

Some really neat videos have come out recently. Marshall Pruett and Racer Magazine posted a paddock walk interview with IMSA president John Doonan, https://www.youtube.com/watch?v=Mr66BZp3Xec&t=3s

There's a whole raft of great tech videos from Racer talking about the MGU systems in the new GTPs, sound comparisons, an explanation on the ESS and alot more. Definitely check them out on the Racer youtube channel.

He also posted his interview with Kat Legge and Sheena Monk, https://www.youtube.com/watch?v=hNhkLoceUDE

And Acura/HPD have released a 50 minute documentary about their road to GTP, awesome, https://www.youtube.com/watch?v=uCcb7is2CJI

Also, figured I'd share this guy's video previewing the race since he's a cool canadian and has been putting alot of effort into his IMSA videos, https://www.youtube.com/watch?v=a2uSXDoK4MI

Enjoy guys and gals!

I have only watched the first few mintues so far and will watch it all later - however I like how they just do not mention and skip over the ARX-04

[MGDavid]

Would there be a simple schedule / timetable without all the non-racing carp but with adjustment for UK or European time please?
In true US style I cannot make head nor tail of the official sites.

Not sure what's challenging about the timetable on IMSA

Bottom of the page is a simple chart of series and time they're on track each day

[Adam43]

5 hours difference. 1:35PM local EST, so IMSA TV at 6:35PM GMT and you’ll be grand.

No ads, Radio Le Mans. Boom!

Edit: works out well, finishes a little before the football.

[PhilipR]

BOP ALERT!

What is the incentive to debut a new gt3 car at Daytona if you are going to be bopped out of the race? Last year BMW and Corvette were slow and this year the Ferrari, Lmabo and Porsche(very) are slow. I understand IMSA trying to be conservative and work the BOP up from a lower point
This is biggest race of the season in the US and most be demotivating to stand no chance due to BOP
These companies could debut the new gt3s later on in the season or if they want race data they can debut one or two new cars and leave their established teams(i.e Risi, Pfaff, Iron Lynx) to run with the old model so they stand a better chance.

[Simmi]

Do we have enough info to truly say at this point? The true BoP game is played right up until the green flag.

You've literally described what they all know going in, the GT3s have provisional homologation and IMSA can adjust up to the start of the race at their discretion. The teams already know this and could skip the round if they desired or felt it was unfair. But remember you still have to make it 24 hours and cars to get taken out but others incompetence and Merriman is in the race right?

I feel a drinking game update coming on

thanks, that helps (a bit).
So the race is 1.40 to 1.40? odd time!
No preamble and 20 minutes wrap-up after?
I don't get the two listings on the Sunday which are identically named...

For him or us?

Also, update your class colors. MDK has moved to GTD Pro, sounds like for all enduros as well.

No dropdown menus! I confess I don't have the patience to scroll right down every page - like looking for a needle in a haystack.

RACER Magazine has released a digital magazine exclusive to the Rolex24. Pretty cool, figured I'd share here. https://www.racermagazine-digital.co...preview/Cover/


Listening in on FP1 on IMSA radio, following along on alkamel timing etc, a good number of red flags so far for minor offs and technicals. So far, with 30 minutes to go as of posting this, the new porker 911s seem to still be struggling () along with the new 296s. THe new Lambos look to have picked up some pace on average across GT Pro and Am. Anyone willing to place bets on Ferrari and Porsche doing just fine during the actual race?

I forgot we had on track action today!!!

And i turn it on to find a Red Flag! Seems to have been a GT thing this time.

Edit; and the Porsche and Ferrari will do fine with constant yellows they won't have time to drop down the order on pace before the car "comes alive" in the dark.
