As F1 shows, development is what wins races. And we are now on a different timeline for the 928.

(Edit: And money) I understand this is anecdotal - but a modern chassis is just so much undeniably more developed. What if someone shows up in a properly cooled Z06 and wishes to run T1? How much can they modify it from stock and still be in T1? That car would smash. Is a GT3 RS like car going to be in T1? With an 8 speed or whatever PDK?

Exactly To this point a new stock Porsche GT2rs did a 1:21 at Willow Springs. My best ever is a 1:23 in my 928 that weighed 1k lbs less and had more rubber. We are driving vintage cars.

Most of the guys running a GT2RS are bringing multiple sets of brand new technology tires, to the track.

If you had run multiple sets of brand new high tech tires, where each set of tires did the exact same thing (which allowed you to set-up your suspension to take full advantage of these tires) how much faster could you go?

Now, if you only added modern racing ABS to those new technology tires , how much faster could you have been?

.........I'm betting that if we had the money that a GT2RS cost, invested in a 928, the 928 would be faster.

I can see that. You get what, 350k to spend, and you end up making a race car that has the silhouette of a 928. As you know, you can drive the GT2RS to dinner with your wife, and it has A/C and bluetooth. :)

For those of you playing at home:
this is the man at Willow Springs...
I’ll take vintage any day :)

For 350K, I'd put bluetooth and A/C in your new 928 racecar.....

I was very excited to see what the results would be when that 944GTR got "fitted" with a 928 engine. 600 horsepower, current suspension, brakes, a 962 transmission, and ABS would make a 944 GTR extremely fast. Unfortunately, the engine expired quickly, the car got sat on a shelf, and was finally sold. I have not heard if there has been any progress made. (The car came with all the pieces to turn it back into a 944GTR....that probably would be the "smart" thing to do, financially.)

For that $350k I'd buy the GT3RS Touring, jack up the 928, then drive away in the GT3RS Touring. The state of the art has changed over three times in the last 30+ years since Mark's 928 was born. Better springs and tire valves, for instance.

Absolutely no doubt.

But look at those cars....they have over100K invested in them, too. Probably way more.


My point is simple.

The SCCA isn't stupid. They know that a well developed 928 with modern stuff on it can compete (and win) in the class it is already in.

Just because one person doesn't want/can not bring their 928 up to those standards means all 928's need to be re-classed?

And then, someone who sees this, brings a well prepared 928 to that class and dominates?

That's exactly what the SCCA is trying to avoid....

Understood. But I still wouldn't kick a GT2RS out of bed for eating crackers.

And I love 928s.

Mark, when will you be racing next? We’ll come along to watch!

This seems appropriate...
