Not that UTQG ratings are completely indicative of performance but Trofeo R is typically quicker than MPSC2. Versus MPSC2R? Don’t have any experience there but have heard they are comparable.

MPSC2 - 180 UTQG
MPSC2R - 140
Trofeo R - 60
Trofeo RS - ??
Hoosier A7/R7 - 40

Anyways, if MPSC2R was worth 7-8 seconds vs. MPSC2, I could see Trofeo RS being worth another 5 seconds or more vs. (a smaller) MPSC2R.

Then add the assumed additional engine power, downforce, track width, and air brake effect….

We’ve seen that the rev limiter has been revised (which is a significant technological change IMO)…. So, I wouldn’t be surprised if other engine management and/or chassis management has also been update/upgraded.

I think 10 seconds vs. 992 GT3 is a bit conservative but 6:45 is certainly very very respectable. I don’t know how it’ll translate to my home tracks but can run some simulations. I’d assume if 10 seconds over 6:55 lap, it’ll be <3.4 seconds over a 2:20 lap……. So, not ground breaking by any means.

However, 15-17 seconds over 6:55 lap would equate to about 5-6 seconds which starts getting very significant. Especially after applying aftermarket exhaust, 19” wheels, and legitimate tires.

 

CUP2R is 1 to 1.5s per minute quicker than MPSC2 on a GT3 RS. Trofeo R is better than MPSC2 but not as quick as a CUP2R, however, it is more stable than CUP2R and less peaky.

 

Note Pirelli are updating/grading the Trofeo R - so those fitted on the new RS may be substantially better.

 

I’m willing to go out on a limb to bet that they’re called “Trofeo RS”……

 

Almost certainly It would be interesting to know why Porsche went to Pirelli? My thoughts are, (1) Michelin manufactured the CUP2R on a campaign basis and thus supply was patchy for large section tires and (2) the CUP2R may be a skim hence its relatively high UTQG rating e.g. a layer of sticky stuff that doesn't last very long followed by a hard compound that gives them some semblance of life. (3) The Pirelli will be sticky all the way through and provide multi-lap performance and stability. (4) The Pirelli will have better wet weather performance (so long as wheels are within OEM camber).

PS the CUP2R is an excellent fast tire for a cpl of hot laps but doesn't have good longevity and in my view the sidewall is very soft - its wet weather performance is abysmal even from new. Outside of a true slick, this is the only tire I have driven on that immediately lifts on the front to hydroplane with the smallest amount of standing water. In contrast, the conventional MPSC2, is not a good track tire, merely OK and it also not a good road tire c.f. MPS4S and MPS5S.

For reference the CUP2RS longitudinal tread depth measurements are ~4mm, 4mm and 2mm; for the CUP2 the measurements are ~6mm, 6mm and 4mm.

 

"We’ve seen that the rev limiter has been revised (which is a significant technological change IMO)…. "
Huh? What does this mean? Nothing above 9000 RPM has been confirmed?? Do you mean the way the car bangs off the limiter in PDK-s?

 

it will rev to 9500

 

yeah if redline goes to 9500 rpm there is no way power would still remain unchanged at around 520-30.

most likely actual power is closer to 550-570 given the 500 rpm increase but will be quoted at around 520-530 officially.

it would make NO sense to incur the increase in mechanical fragility coming from 500 more rpm without a significant power bump.

 

Or more virtue signaling.

 

Sorry if this has been mentioned, I am catching up in this thread. Just got a mail from my dealer about the online reveal on Aug 17th. Strangely it says "about 500hp". Very vague.
Again, sorry for repeat post if so.

 

Almost certainly. For my GT3, the announcement was in Feb 21 and I had a late June 21 build initially. I think the Euro guys will start taking delivery by the end of this year.

I think that was the most interesting part of the entire press release. "About 500 hp" implies a number very close to 500hp.

 

yes, “the way the car bangs off the limiter”.

Look at a dyno graph of the most recent GT3s and GT3RSs. All of them start losing power at a significant rate as they approach 9000rpm. A higher rev limit will not increase rated power.

 

A higher redline on its own won’t help, but a change to camshafts (or software change for the Variocam tuning) and/or better intake breathing could make a power and performance increase at a peak power point above 8,400 rpm very possible. The 4.0L RSR race engines were continuing to build power above 9k.

 

i agree, internal changes and bolt ons /ecu changes they can shape the power curve however they want. They are limited by regulations but porsche is a pretty good mod company. They did pretty well modding beetles for the last 70 years lol

 

Johnny Depp is going to pour himself a mega pint of wine after seeing this car! I know I'm about to.

Pretty excited... the RS is looking a little nasty.
