and with a tune will likely be quicker than the gt3!

the new BMW M3/m4 already are getting over 500 hp with tune, and their twin turbo is 3 L as well.

so this begs the question, what next for the GT3 ... will it use the 991 GT3 RS engine and exceed the 500bhp limit ... or will they go the weight reduction route?

Very recent rumors indicate GT range is going turbo also with 992. So facelift coming in a year or two will be last NA GT3. Don't shoot messenger - just repeating rumor from German forum...

Those with NA GT cars hold onto them!

That rumor seems to be opposite to everything AP suggested. I'm certain they'll keep the N/A engine for the GT's. At least for the 991.2. Things may be different once hybrid technology trickles down. Everything is just a rumor now.

Are we talking drag racing or lap times? I can't see how a bump in torque would make that big of a difference. But truth be told, even the 991.1 S isn't that much slower on track than the 991 GT3.

I wrote that 991.2 GT3 keeps NA...

GrantG

I think it depends on the track. My local track is over 5,000ft elevation and I bet the new turbo C2S will be considerably faster than a GT3 on a laptime basis.

At sea level, the extra torque is a bigger benefit on cars with less than optimal gearing. The PDK-S is very good in that respect, so the extra torque won't be that big an advantage on most tracks.

But with 430hp in S trim and ~460hp in Powerkit X51 trim, I would think the new C2S would put up quite a good fight against the 991.1 GT3. Should have manual gearbox option too. Probably going to be an momentary overboost feature too...

Sorry Grant. Misread 992 as 991.2

GrantG

No problem

do the FIA homologation rules allow turbocharged powerplants in GT3 class, I thought not, hence a turbo GT3 cant be a GT3, at least not a homologation platform IMO.

What I've heard from a dealer here is that the maximum HP from the current GT3RS engine is 540. The 991.2 version will get 520 up from the current 500.
BUT the same guy says that ALL Porsches will be boosted by 2019.

ipse dixit

I thought the FIA regs for the GT3 class was more about horsepower (i.e. between 500-600 bhp), as well as other things like dry weight, and not necessarily the type or layout of the engine.

I could be wrong (and probably am) but wasn't Nissan running the GT-R Nismo GT3 that was spec'd with the VR38DETT, a twin-turbocharged V6 engine, putting out 600 hp?
