we don't really know how much heat that is going to be generated/felt by windows down, I think AP's comment may have been tongue in cheek.
I mean the hot air is being deflected laterally but am sure is getting mixed also with ambient air in current setup. Whereas before deflectors and strakes they hot air would have been flowing straight into the air intakes at speed. Will have to see when reviews come out.

Why mention it then and also say the car would lose 20 HP without the roof strakes??
LOL

I’m surprised they bothered with the boomerang stuff / doing away with the frunk + the roof strakes etc-- a lot of stuffing about for relatively small gains, makes me wonder.
How much extra air density / heat would be needed for +20hp over 500?
I’m guessing you will not even notice the heat at speed, will be interesting to see

marketing?

Check the math, air density is huge for a NA engine. For easy reference look at performance graphs for NA planes. Your will see how big it is.
Frankly, feeding the engine with 135+ air temps is likely more than 20hp.

Lap times don’t lie. It’s in the data. You can’t ask any “average” track rat the difference in power between the summer and winter. Just ask AP why they don’t have a lap time…

Come on we all can tell the difference in engine performance on a cool vs warm day etc.
Question is from a design point of view the concept of
making a choice then having to come up with work arounds to deal with its shortcomings is not very elegant.
I think the strakes are badass sexy and the boomerang concept etc. cool but they are workarounds.

It really smells like the car isn’t fully baked, as hinted in the AP videos disruption likely inhibited a few plans.

I mean the hot air is being deflected laterally but am sure is getting mixed also with ambient air in current setup. Whereas before front deflectors and strakes the hot air would have been flowing straight into the air intakes at speed where a few degrees warmer air at max power could have robbed '20 hp' on a cool day. Will have to see when reviews come out.

This is a miss.
Wait for the .2 with the 4.2.

I recall a thumbrule that every 10 degrees is about 1% hp in an NA engine. So for ~500 hp that is about 20hp for a 40 degree drop in ambient temperature. Not a lot but enough to make a difference on a 12.9 mile course.
I'll say it again but I think the ring time was done and it was not really good so Porsche is waiting for temps to come down. Only 15hp more than the GT3, but higher drag and lower top speed. They didn't want to come out with a disappointing number at press launch.....so that's the story. The car is down on power for the added aero.
I personally don't care. I'm not going to be driving on the Ring (actually I will but only once). I think on most tracks that people drive on, the GT3 will be neck and neck with the RS. Essentially no difference.

992.2 GT3 is sounding really appealing. Or even 992.1 GT3. Or for those of us who already have 991 GT3/RS, maybe just keep that. My 991.1 GT3 is now 7 years old, and is still a beast.
