Well that is an easy fix, just ask ACO for bigger tank. cough cough Aston cough cough...

Late reply, but when I see that utterly gorgeous red and white livery.....

[PascaLM]

DéjÃ* vu, but I prefer this classical red livery.

The PRINTED version of the guide went to press ages ago and has the old livery. The DIGITAL version of the guide will be available Monday ish on SpotterGuides.com and has the new livery

Viper running a special one-off livery on the #91 car at Indy...



IT automotive is a new sponsor thatll be on the vipers for the rest of the season.

[Articus]

I might confuse this car with the GTD one.

This press release makes a bit more sense. Basically, it's the equivalent of a corporate IOU.

"That's as good as money, sir. Those are IOU's."

Add this to the wild rumor mill--Volkswagen Group is rumored to be at least thinking of buying some stake in Fiat/Chrysler:

Potential for Porsche and Ferrari to be owned by the same parent. Not sure what to think about that.

A new rumor says that the interest of the VW group is only for Alfa Romeo

Heres the full livery for the #91



Looks good!

[joeb]

That does look good. I didn't realize how much the old livery was hiding until they put the red on and now this.

[pederb]

Amazing what a little paint will do

As soon as they went back to red, they win everywhere

Congrats

Didn't realize that the restrictor table was straightout shown on the GTE "regs"

So as we knew, the pre-bopped base restrictor value of the 8 liter Viper is 28,1mm (= 5 liter class) while 5,5 liter Corvette's pre-bopped base restrictor is 27,9mm (= 5,5 liter class). Which makes no sense apart from the obvious politics shenanigans but whatever...

I'm bad at maths, what should the restrictor value for 8 liter really be? 27.X something. The mm differences in the table are not directly comparable, for example the difference between 4000-4500 is 0,3mm, but difference of 4500-5000 is 0,2mm?

That restrictor table is for vehicles at 1245kg, so as the weight is adjusted the restrictor size can also be adjusted. Also the relationship between restrictor size and engine displacement is not linear, so as the engine gets bigger the difference in restrictor size is less and less.

Incorrect, all LMGTE cars have the 'minimum' pre-BoP weight of 1245kg, as does the Viper too (the extra weight is BoP weight), you can check this from the earlier ACO BoP charts as well. Them having pre-BoP restrictor size at 5 liter displacement slot is purely political.

Anyway, righto on the non linear displacement chart.

[kyoung]

I have not ranted about BoP or now AoP in a long time…

They set up rules for manufacturers to level the field for a large variety of cars, OK that makes sense.

Then they allow manufacturers to run outside the rules if they are not competitive, this does not make sense.

On the math problem, there is a point where the restricted air goes supersonic and creates a vacuum and cuts power to the engine essentially creating a rev limiter. My best guess is you would have to know displacement and max revs of every engine to calculate restrictor size. They probably get their baseline data from the homologated cars in that class.

The problem I have with the endless adjustments is the injustice of taking a slower car and making it faster than another car that is following their rules? But we all know the reason, you ever hear that song “Every 1's a Winner"?

I also see that they have done away with the break for two valve per cylinder engines. Anybody know when that happened, was it the same time they went to the 5.5 liter max displacement rule that also doesn't seem to be a real rule?

Even that's not really true as the cars receive waivers and BoP (new Porsche and BMW for example) before they have ever even run.

[kyoung]

I understand what you are saying, so without becoming too pedantic…

I don’t distinguish between waivers and BoP, waivers are just another end run around rules clearly (maybe not, but should be) defined in the regulations.

IMHO if the regulations were clear and properly written there would be no reason for waivers.

Again, it’s been a while since I complained about BoP and for good reason, it’s a pointless exercise.

It is what it is, I enjoy the GT circus or watch something else when it gets tedious and predictable.

Viper's gtlm program is done

[Rodger Davies]

Well, there goes GTLM. Such a shame, having only taken the car to Le Mans once, but not unexpected unfortunately.

Many talented people in there, I hope they have success finding work elsewhere.

Not good! They were strong competitors and will be missed. That just really really sucks.
