Mazda leads 1-2 in night practice

If they last 4 hours, there's totally a chance in the sprint races. Too bad they're not coming to Austin.

As if 7th and 9th in qualifying didn't hurt enough, the team was penalized for taping seams. Last in their class for start in 15th and 16th. We have Joest, but where's the luck?

I think Joest has bitten off more than they bargained for with these snake-bitten Mazdas. Anyone missing Speedsource now ?

After 10 hours, 55 is 3rd overall and less than a lap behind the leader. 77 is in 9th.
Considering they started at the back of the class, there's a really good chance for a win in the rest of the season. It's all down hill from here.

I know I do. After the rotaries were discontinued they were saddled with that slow diesel engine for 3 years, then an old Lola for a year, and then they weren't even allowed a season with the RT24.

Well, both Mazda's finished the race, which is an improvement.
#55 was 1 lap down in 6th place, and #77 was 10 laps down in 8th place.

#55 was on the lead lap when they came back from a yellow flag, and then chose to go into the pits.
#77 decided that 3 minutes left in the race was also a good time to pit, which makes me wonder what is going on with these teams and their pit crews.

BC.

#55 was 2nd place when it pitted around 38 minutes, and then couldn't restart. had to push start, failed once, and then second push start it worked.. then it was down 2 laps. By the end of the race, it only caught up 1 lap...

Terrible fate... they risked their pit strategy (probably had to get fuel one last time), and their gamble lost.

like not having clutches that don't let them exit the pit lane. that would be progress.

Like i said before, Joest has bitten off more than they can chew with these cars. If they can't go long enough on fuel, or they can't restart in the pits, then their only hope is in shorter races going forward. No chance for much in season standings that way. A lot of Mazda money is being wasted with these cars. And what benefit is this giving them in the showroom with this unreliable performance ? You can say what you will about rotaries but the racing RX7s and RX8s were reliable for the majority of their class winning race history. Too bad they can't run them anymore, too many years past last production.

There is a solution to that.
Mazda just has to do what needs to be done.

But its too late for this season.
Let's not repeat last years mid season pull out again, if possible.

Unfortunately, Joest is in a "here you go, make it work" situation. They inherited underdeveloped cars that had issue's and they are getting them sorted. I would say that the 12hours was a much better overall result than we have seen in the past. Sure, their not there yet, but at least they no longer appear to be lost.

They were running at a strong pace, both cars finished the race and nothing caught fire. It appears as if they are headed in the right direction finally. Perhaps not as quickly as we would like to see or with the engines we would prefer but not stagnant in their efforts.

Go Joest/Mazda!

We all want them to succeed, but I think this engine is not the winner that Mazda hopes it will be , against the best from the other teams. IMO
I forgot, how many years is the Joest/Mazda contract ?

sorry guys been on vacation for 2 week and hadn't had time to post.
I think some of you are giving up on this Team far too quickly, Mazda was LEADING the race at one piont and had not been for what, a battery issue they would likely have been on the podium and probably contending for an overall win.

I think this team is definitely moving in the right direction, they seem to have figured out the heating issues, the cars were more reliable than ever before, and they finally have the pace to run with the front of the pack.
I absolutely expect them to be contending this season for podium finishes

It all remains to be seen if Joest can save this season from its teething pains. Cheers

we're only 2 races in and those two races both happen to be endurance races where we knew Mazda would have issues.
The car is in MUCH better shape than it's ever been so I'm still confident.

This month's Racecar Engineering magazine has an article on Joest's work on the RT24-P.

Here are some excerpts:
One of the first DPi Mazdas was delivered to Joest’s workshops in Germany, and work immediately began in turning it into a competitive car. That process included a general tidying of the cockpit and particularly focussed at the rear of the car in terms of cooling and suspension layout. ‘I saw the very old car that came to the workshop in Germany and is still there,’ says team manager Ralf Juttner. ‘It was a shock to see that. This is still not what a racecar should look like; that was a nightmare. Looking at our situation now, hats off to SpeedSource that they ran with two racecars at all, but why didn’t they use the second half of the year to clean up what was obviously a ‘get it ready somehow’ car? There was no cleaning up process. For example, they had a drinks system in it, welded aluminium. [Drivers] Jonathan [Bomarito] and Tristan [Nunez] were in Germany with us, and I asked how much are you drinking in the stint? They said not much, because it doesn’t work anyway. It looked like a small nuclear power plant!’
If Speedsource received the car in the summer of 2016 and it was still in that state by Daytona 2017, I could see why Doonan was quick to hire Joest before the flag dropped.
However, they were running a race program at the same time unlike Joest which had 6 months of just R&D time.

But now Multimatic has taken on sole development of the chassis, and put former Lola designer Julian Sole on the case.
...
The overheating issue on the original racecar Sole mentions above had led to some rather unusual solutions. The radiators were stood up in the sidepods, with a reduced size compared to when the engine ran in a Lola. So the first job was to improve the internal design and airflow. ‘I heard even with temperatures like this [speaking at a freezing cold Daytona at the ROAR before the 24 test in January], they would have struggled with the old cars,’ says Juttner. ‘They ran that engine in the Lolas, and they were on the limit, and then Riley made the radiators 70 per cent the size of the Lola. We have gone for bigger radiators. The radiators were standing on the left, and behind that was the big inlet for the turbo, so 60 to 70 per cent was blocked. The car that we received in Germany, they had a constantly blowing ventilator for the radiator to survive somehow. Now they are angled, bigger, and the inlet configuration is different.’
Yep, Riley screwed the pooch on the chassis.

Hey I have been part (as crew and photographer) of championship winning racing teams in SCCA and IMSA including VW & Mazda (Valvoline/Inner City Youth Racing); Mazda (Z&W), and Porsche (Al Holbert) teams ,so I do know that this process takes time. Yes the shorter races may yield better results. I guess I am spoiled for how well the rotary and Porsche teams did in endurance races.

I did not know the full extent of how poorly the previous Mazda prototype cars were designed, under the skin.

Long Beach is this weekend, you guys ready?

IMSA handed out some BoP adjustments for the race and it should be interesting to see how that affects the cars. (Mazda changes in bold)

All four DPi manufacturers have been hit with Balance of Performance changes ahead of next weekend’s IMSA WeatherTech SportsCar Championship round at Long Beach.

There have been boost reductions across the board for the three teams running turbocharged prototypes.
The Acura ARX-05, Mazda RT24-P and Mobil 1 Twelve Hours of Sebring-winning Nissan Onroak DPi have all had their boost levels affected for the first sprint race of the year.

Cadillac’s DPi-V.R, meanwhile, will run with a 0.6 mm smaller air restrictor than it had at Sebring, while the Joest-run Mazda DPis have also been been hit with a 10 kg weight increase.

No aero changes have been made to the Prototype category, which has 14 cars listed for the third round of the season.

All four DPi manufacturers, however, will have reduced fuel capacities, with Acura and Nissan losing 3 liters, Cadillac 2 liters less and the Mazda getting handed a considerable 7-liter decrease.
The changes come amid a dominant run from DPis at Sebring, which saw the global-spec LMP2 cars, which are not subject to BoP adjustments by IMSA, struggle to match the pace in the 12-hour race.
less boost and fuel restriction?
ouch.
Lets hope it doesn't hurt their pace too much and they can maintain a similar fuel strategy to the rest of the pack.

1st practice of the day is in the books and Mazda is showing good speed.
  • Action express was fastest with a lap of 1m13.582s
  • The #77 of Mazda was 5th with a lap of 1m13.743s

although there's 3 cars between them and the leader, that's a pretty good pace so far.
There's a 2nd practice later today and then we'll see what the cars really have in them when they qualify later today.

4th (77) and 9th (55) which is not quite better than last year.

Jarvis in 77 had a good tussle with an Acura towards the end, but an LMP2 and Cadillac got by Bomarito (55) during the last several minutes. I think the BoP adjustments hurt Mazda and Acura more than the Cadillacs.

I'm starting to think that that is the point.

I can't understand how a race car, that already makes less power than every other engine in the series, needs to have its power levels reduced, more weight added, and have their fuel load decreased.

In what alternate universe is that Balanced and Fair?
