IMSA: USCR 2018

[canaglia]

Likely it could be an old engine, but to take part to a test with a close to end lifespan engine is a reg. violation?

"Different cylinder's size, and different compression"
well... not the best idea for an endurance engine.... it would be critically unstable. Remind me a year in GT1 when corvette racing was able to turn off 4 cylinders during FYP at le mans and the engine basically blew because of this.

[Purist]

Yeah, I don't think they'd take an engine before the test was over, unless there was an express rules violation, or a strong, credible suspicion of such conduct.

You do wonder at least a little about WTR's performance in 2017, even compared to the other Cadillacs.

I thought about this many times. But I think that with the BoP changes after Daytona , the Taylor brothers found a great setup (mostly for Ricky) using less rear wing to avoid understeer. In the next races the faster Ricky was, the slower Jordan was, and that's the reason that makes me wonder about all this. The other two Cadillacs couldn't compete for the pole while Ricky was driving.

I think next year will be another story because of the new splitter from the Dallara base car, at least this is my theory.

Full season GTD entry for Wright Motorsports with a Porsche. Drivers are Patrick Long and Christina Nielsen.

at the end, Christina's got a gun (quite not difficult with her wallet)

That is good news, I was wondering where she would end up. Good to see Wright commit to a full season too.

It wasn't a blown engine if it's the same incident I'm thinking of (Le Mans 2007), cutting cylinders caused vibrations that shook a new carbon fiber propshaft to pieces even at SC speeds.

Yep, Corvette was running displacement on demand that year. It's common on road cars now, but it's not seen much application in racing, probably because of issues that Corvette were having. They had problems also with one car at St. Petersburg during the ALMS race there that year with a broken driveshaft.

That was exactly it and they were caught driving the car back to the pits on the starter motor because the engine had cut out and the driveshaft couldn't spin the engine to restart. Apparently they mounted the starter to the rear end housing not the engine, probably makes for faster changes than punching holes in Oreca bodywork for the starter hammer.

[chernaudi]

Corvettes also had a transaxle gearbox back then (and had since '01) which is probably why the starter was mounted there. Of course, the ACO officials didn't like what they were trying to do and made them stop the car.

BTW, anyone know or think anyone's running DOD on current prototype or GT engines? I haven't heard of its use since a decade ago when Corvette tried it and gave up on it after LM.

unlikely, and not for just reliability issues, but I guess it doesn't worth because of bop. In GTE each car has different fuel tank size to guarantee the same 60-65 minutes stint lenght for everyone.
If a car is able to save somehow some fuel, there will be a likely fuel tank cut next races

[chernaudi]

Only problem with BOP is that you can't judge how many yellows there will be in a race or how long they might last.

I'd bet that teams would rather shut off their cars and coast than use displacement on demand (which comes with its own risks). If you have a V8, turning it into a big inline 4 or V4 won't help with NVH (noise/vibration/harshness).

[canaglia]

well; ford, bmw, ferrari and aston could turn off turbos in the meanwhile. Just in theory of couse.

[Purist]

Just an fyi.

Check the "IMSA Official" YouTube channel. Yesterday, they posted up six races: GTP Watkins Glen 1989 and '91-93, GTP Mid Ohio 1993, and GTP Sears Point 1989. Up to now, today, they've added GTP Road America 1993.

Also, last week, Marshall Pruett of RACER posted GTP Charlotte 1985, and yesterday, he added GTO Mid Ohio 1990 to his YouTube channel.

Have fun.

Thanks for sharing ! I took this week off !

I saw the 1993 Watkins Glen and Road America races in the past couple days.. It was cool to see the GTS cars in particular. I loved the Nissan 300ZX. Olds was cool too. Unfortunate that Nismo does not build the new GT3 car with those styling and paint looks. A GTE Nismo could go by that theoretically.

Hopefully IMSA official will post races from the mid to late 90's as well. Not because I love the WSC class. No I hated them. But I loved GTS/GT1 back then. Nissan 300ZX was the first GT car I feel in love with, then came the Lister Storm, then Panoz GTR1, then Porsche GT1.

[MaskedRacer]

Will be cheering for the Porsches or Risi Ferrari to win the Daytona 24. The later because if they are in championship contention after the 36 hours of Florida, then perhaps they can get funding to run the full season. Otherwise I can see them taking off races in the mid season again and only come back for the fall stretch.

[Purist]

Yeah, I'd really like to see Risi keep up a full-time effort. It would also be kind of nice if AF Corsa, Scuderia Corsa, or whoever, would bolster the Ferrari contingent over here.

As for IMSA in the '90s, from the early GTS class, my pick is probably the Mustang driven by Tommy Kendall.

As for WSC, the drop in performance from GTP didn't help, but perhaps worse was the fact that a number of the cars just weren't that inspiring to look at. There were too many Riley & Scotts and Kudzus to be balanced out by the Ferrari 333SPs, Spice AK93/HC94/SC95/BDG-02 Oldsmobiles, and the lone Gunnar Porsche 966.

Speaking of that convertible 962, is it just me, or was the Ascari A410 LMP900 a Lola T92/10 with the roof chopped off?

As for the coming season, I'm waiting to see how the RLL BMW M8s look in their actual racing livery.

That's essentially exactly what it was.

While I'm happy to see Gainsco on the old 85, I will lament the loss of the OG Banana Boat.
