There are a lot of factors beyond technology. In professional racing costs are so high that business factors determine a lot.

These series have rules about specs for every marque about weight and total airflow to the engine that are designed to "equalize" competition among marques. The sanctioning bodies adjust the rules all the time to keep the races competitive and bring in the fans.

The manufacturers play because more fans show up where it counts- where the sponsors place ads. When they don't think they can compete, or that they can do more effective things to sell the brand, they stop spending the money.

This year the rules ended up favoring other marques in these classes, but in recent years the sanctioning bodies have done pretty well at generating great competition.

Politics (or outright favoritism/bribery).

BOP favours cars with the most flexibility e.g. ability to alter aero, ability to alter engine performance ranges and thresholds etc

If you want a recreational sports car that can entertain enthusiast drivers on both street and track, has practical packaging, rewards the acquisition of skill and excels at braking and accelerating (where payoffs are highest), then sling the engine down low just behind the rear axle.

Each of these is, in fact, the very best location for its intended purpose. The question is: what do you want?

The issue is that the 911 exists in the real world. While the naysayers live in the theory world...

In theory the 911 shouldn't be successful due to it's supposed " flawed " engine placement ...

In the real world , however, it has dominated racing since nearly it's inception and currently holds the Ring fastest production car time OVER it's " technologically superior " mid engine and AWD hyper car brother the 918.

EXACTLY. And that goes back to the larger point....

We can all hypothesize how it “shouldn’t/wouldn’t/couldn’t,” but in real life it IS. Thus comes to a “proof is in the pudding” scenario.

It’s hard for me to believe anything otherwise than Porsche’s secret sauce having it right all along.

Would be interesting to put equivalent tires from the GT2RS on the 918 and see what lap times it would get...

True. Though one can say it would also be interesting to see what times a rear engined Porsche can put up with 887 HP. I’d imagine, considering the GT2’s performance, far beyond the 918 with even equal tires.

Like the old joke about scientists or engineers, theory proves that bumblebees cannot fly, but...

F1 cars have the engine behind the driver! Case closed!

In the recent Ring record, the GT2RS has special tires? I'm not aware of that. Please tell us more. I thought possibly, the only thing they did was use motorsport tire warmers?

Joke, right? they are mid engined, the proper way to build a sports car.

True but still behind the driver as I stated!

They did use warmers (rightly so) and the tires were MPSC2 N2 spec (e.g. latest iteration).

K-A you probably should take a 996GT3 round a track and then deliver your thoughts on engine placement and perhaps consider why Porsche extended the wheel base of the 991 and gifted RAS to the 991.2
