I thought it was smoke and fire or was the fire from the pistons exiting?

I like the two tone black / maroon. Is that maroon??

You know, I can't help but note the time left on the clock when that happened. Things like that tell me that despite AER's issues, despite all the joking, there really should be enough potential in those engines to do the job with a team like Joest helping out.

[Akrapovic]

The AER units weren't particularly reliable when run by Rebellion, ByKolles or Dyson either. There's a common factor in all of these.

Very true, indeed!

Don't forget that at 2016 PLM, they actually made the 1,000 miles before cablamo, so they at least lasted MUCH longer than any Dyson AER / MG.

I posted those pics in the Daytona thread mainly to take jabs at joeb, cause that's fun!

I had to look twice to make sure you were actually the one posting after that comment.

But then I was good to see you back in top form with this one :ROFL:

[Damian Baldi]

In this picture is noticeable the change on the dampers/ spring arrangement (from the Riley way to the standard way). At the front the car seems to maintain the original arrangement.

They crap out a the same percentage of total race completion.

[RWill2073]

As far as livery, why not just paint it black and grey? Gonna end up that color after the fire anyway.

I'm okay with Mazdas. It's you I have issues with

Indeed, have fun with the bizarro tigers this weekend

[TF110]

Looks good up front but the rest of the car is pretty basic except the 'trimmed down' fenders. Still not a fan of the wide cockpit, but I do like the color. Hopefully they keep it that color this year and not the orangey red one. If they make the AER work, it'll be a miracle.

Marshall Pruett did some interviews with the drivers. The big thing that I took from it was after Nunez got his first podium, Speedsource had him clean the toilets the next week to try and keep the drivers grounded.

I think that kinda sums up the Speedsource effort. Motivate your staff by punishing good results.

Lol, indeed that is nuts!

Did they not think the two years of constant dnf's hadn't kept him grounded enough?

[chernaudi]

And they wonder why they got turned away when Joest showed up aside from being an amateur show since they ditched the RX-8s.

BOP test at Daytona this week should tell us alot, are they likely to release times?

[chernaudi]

If they're using the final 2017 BOP tables as a baseline, I'd be interested to see if the Caddies actually go a bit faster than they did during 24 qualifying (provided that they or no one else sandbags and gets away with it). After all, they're running significantly less downforce than the start of the season last season, and Daytona is probably the least downforce dependent track by far on the IMSA schedule.

For some reference times, Cadillac DPI: 136.9. Audi R8 HSR this year: 137.9 on Goodyear tires vs Continentals on the Caddy.

Also, anyone know of trap speeds for the 2017 24 weekend? I know that one of the R8s during the HSR event was clocked at almost 201mph into the speed trap this year.

I know that's an apples to oranges comparison (LMP900 vs DPI, 2000mm wide car vs a 1900mm one, open vs closed cockpit, Continental DPI tires vs Goodyear (I know that the Audis originally ran on Michelins), etc), but it's as close to comparing something as I know outside of old LMP2 cars and such.

I'm waiting next week's tests with anxiety. There are lot of things to compare and some changes to take in mind.

Ligier and Dallara chassis has received aerodynamic updates. In the case of the Dallara, the change is on the splitter, and as this part is a common part of the P2 car, the Cadillac will change too. I'm not sure about the changes on the Ligier. However, Nissan have changes on their car, mostly on cooling. This is why Onroak is testing the Ligier beside the Nissan DPi with pipo Derani at the wheel.

The Mazda and Riley/Multimatic is another story, because the base P2 car received several changes on suspension and cooling (I'm not sure if it will present aerodynimic changes too), and maybe some weight reduction.

The Oreca chassis remains unchanged, so they only need to compare the Oreca with the Acura.

You can find all the results here


After the december 2016 test, the Cadillacs were forced to change the aerodynamic settings because they reached more than 200 mph

[Bcarr6]

So all in all, at this point, what is everyone's prediction for fastest Proto in the Daytona 24 qualifying?

I think caddies will still be upfront with a heavy challenge from Penske, if Joest get the car in line then Mazda could be up front in quali (can't see them having legs for full race though).

I don't see the P2s quite challenging, and I reckon the Nissan will be more a race pace car than a qualifier

This brings up something I've always wondered. How does the team end up owning so many of the cars when they're 'factory' owned, built and run cars?

I think it works as a franchise, in this case Mazda is the sponsor and owner of the brand rights, and puts on Speedsource the role of executor. The chassis were always Lola (later Multimatic), so Mazda don't owns intelectual rights over the chasis. In other words, the chassis were just a tool.
