lol yeah, someone (not me) add an overboots gage to their car and invalidate their warranty please....

I am 100% sure the 992 does not have an overboost and 100% sure that the only different with SR is gearbox and Turbo spool up, maybe transition and engine mounts. All the links above are to sites that are just guessing.

I'm not a racing driver nor an experience drag strip racer, however, I am fairly sure that how fast your gearbox keeps the engine in the power zone will affect your timings.... It's not just all about power is it. Is it?

There is a boost gauge in the car, in the individual display of the dial 2nd from right.

I guess you know for sure, even though you don't have any facts. Let the facts speak for themselves. Transmissions don't magically change gearing, only shift points. Speculation is what makes the internet a dangerous place.

Yes, definitely over-confident without facts. I do think the discussion is worthwhile though because we are trying to determine if Porsche has ever said or suggested SR triggers overboost. Sounds like the answer is no.

If the car has a boost gauge, should be easy for someone to test. I would do it but my car doesn't get here for a couple weeks.

The problem I have with this is that a 911 doesn't have 15% drivetrain loss. On a RWD, rear engine car, I think it is closer to 8% loss which would put the power right on target from the dyno.

ipse dixit

This is why a 911 always punches above its weight when it comes to stated power/torque numbers on the spec sheets.

mr gregash

Agreed, but the car is not underrated.

I had an M5C and that car WAS underrated. They quoted 617 HP and C&D got 617 WHP which means with an 18% loss (front engine, AWD) it's making over 700 hp.

Assuming you're in a 992S. Do you think your 992 would take the M5C?

I have a 718 GT4.

I think from a roll the M5 would do well and would likely pull since it realistically has about 175 hp more but from a dig the 992S would beat it because the M5C launch control is awful and you usually end up bogging down.

The M5C was quite a boring car to drive. Needed to add a Racechip Black GTS almost right away. And even then it just got old fast and got rid of it. Also didn’t sound all that good either.

As I said. First get your facts. Here is the quote. Check before posting.....

I could consistently get 10.89 with my vBox on my F90 M5C. Looks like the 992S is around 11.3 at best. It's a good difference.

I'm in the market for a 992 C4S and am most looking forward to the lighter weight and sportiness of the 911 compared to the M5. But the M5 was a beast bone stock.

mr gregash

992S is capable of 10s and most 1/4s I’ve seen were 11.1.

Overall, the M5C is a beast and makes around 617 WHP whereas the 992S around 400 so the fast they’re so close in acceleration speaks quite well for the 992S. The 992S is certainly the faster track car if you’re going to track.
The BMWs make tons of power for sure but beyond being a straight line rocket it fails to deliver much else and the weight and size are major detractors for it - they don’t dance the way a Panamera does.

I think you’ll be happier in the 9924S. It’s probably the best all around sports car.
