I think there is going to be a 6-7 second difference. The exit speed difference between the two and braking are going to be huge factors. The GT2 is not going to be able to overcome that. Sellers will be near that 2:11 easily as he is about as high level of a pro as it gets. I will be shocked if the GT2 breaks under the 2:18 range. There are some GT1 race cars pushing the same type of power on slicks having a hard time being anywhere near 2:15s at Road America. That is seriously cooking around there even with big hp.

"It is crazy that we can even contemplate a challenge and yet nobody here dare put their house on the line for certain."
I will go on record and "put my house on the line." It's a nice place...11,000 square feet, 12 acres, pond, full outdoor kitchen, patio, pool, sunken lounge area for scotch and cigars...etc.
Not to sound like a d*ck, but I really can't believe people on this forum actually believe a high powered street car has any chance against a true race car?! Blows my mind.
If you guys are having the same race car driver (and I mean someone that can actually drive a cup 10/10) drive both these cars, the delta will be embarrassing for the GT2 RS.
I would love to own the RS...but it "ain't no race car."
A cool test for entertainment purposes but there is def no mystery on the result.

E diff
RWS
etc
A stock, mediocre driven 500HP 300TQ GT3RS on regular Micheling Pilot Sport CUPs that I drove from Palm Beach FL to Road America does 2:24, by the time I ran those, cords were showing..
So big Power, pro, fresh sticky tires will be much faster then 2:18 IMHO..

I've read the entire thread...there are multiple people truly questioning the outcome of this test as far as "which car is actually going to be faster."
Just stating that I was shocked that people that are car enthusiasts would actually wonder or think that the GT2 RS has a shot of actually beating the Cup Car. Seems ignorant at best.
I was merely stating that I was willing to "bet my house" since it was brought-up that no one had demonstrated that level of certainty regarding the outcome.
This is a no-brainer. Kinda like seeing how close a running race would between an in-shape junior high school boy on the track team vs Usain Bolt.
WE ALREADY KNOW THE OUTCOME!

And telling us that your house is "....11,000 square feet, 12 acres, pond, full outdoor kitchen, patio, pool, sunken lounge area for scotch and cigars...etc...." was totally necessary to make that bet.......
I think if the cars ran equal tires, this would be very close. The grip of the cup car will be its big advantage. The cup car will have upper hand in grip and weight....the gt2rs will have power advantage. Give the gt2rs slicks like the cup car, and we could truly see which car laps faster.
But I wouldnt bet my house on either side of this.....nor will I unnecessarily and gratuitously describe my house.....

SDGT3, David Murry et all - awesome that you are organizing this!!
And as far as predictions...Whoopsy is exactly right...
GT2 RS will be slower than the Cup car everywhere except the second half of any straight.
The Cup car will be faster in braking, turn-in, mid-corner speed, and exit speed.
Net, I am guessing the Cup car will be 2 to 3 seconds faster despite the long straights.
It would be another level of awesome if the GT2 RS had a second set of wheels with Hoosier R7s.
With Hoosiers on the GT2 RS, it could be very much neck and neck with the Cup car.
Looking forward to the outcome!

BRAVO for putting this together. It feels so old school that it’s got us all hyped up for the challenge and can’t wait.
Any chance that a set of R7s can be mounted to the RS for a second attempt on the same day just to see what that delta is because the R7 will most likely be the tire of choice for many reasons to owners.

It should be easy to predict the outcome by looking at lap times of the two cars from other tracks. In general though, grip is king. If you increase grip by say 20%, you're generally going to need way more than 20% increase in power to get the same drop in lap time. Grip wins in braking and especially corners (including "slow" corners, where we wind up spending a significant amount of TIME, which is what matters), and gives a higher corner exit speed. You need a lot of extra power to compensate for lower corner exit speed in order to make up time on straights, since even powerful cars have limited acceleration at high speeds (remember that, as a car is approaching its top speed, it's acceleration potential is approaching zero).
Have you guys ever noticed how people with low-power cars like to brag about how little power they have, but fail to mention that they've taken pains to increase their grip? They also usually forget to mention how light their cars are.

This has so much sponsorship potential for track day and race suppliers.
Michelin is asleep at the wheel, Pirelli is on point, PCA is behind it, VBOX, Track Insurance guys, video crews and editors, if you ever wanted a crap load of viral free Social Media advertising, this is it!!
