The engine will be similar in concept and architecture but will by no means be "the same."

The RSR crate engine - if one were able to purchase one from the factory, which will not be possible of course - would very likely cost more than the RS street car's MSRP.

The RSR produces 510 bhp WITH a sonic restrictor fitted. Everyone seems to be overlooking this.

The outgoing 4.0 RSR engine, based on the ancestral Mezger engine, redlined at 11,500 RPM in race trim.

Is quite simple just read FIA WEC regulations

they don t allow so many differences between
race and the street engine versions especially when it comes to Ti etc.

you might also wonder why .1 RSR asked for rebuild every 50 hours whilst .2 RSR is 100 hours..

Manual transmission cars will not be able to have a wing? That can't be right...

I think the only people that have seen the RSR outside of PMS are maybe the guys over at CORE? So nobody really knows anything yet... We can guess based on the motorsports catalogs from the last 20-30 years! HERE's the parts catalog for the last model year that the RSR "shared" an engine with a street car of the same year (997). This same engine was massaged over the last 2-3 years and was shoe-horned into something resembling a 991-C4 chassis.

Let's just hope whatever the next GT3 engine is, it will be more reliable than the current .1

The 996 GT3 R/RS/RS and Cups and the 997 GT3 R/RSR and Cups shared the engine block with the street cars. How much of the rest of those engines were shared with the street cars?

It would be great if someone can answer that question. I think it would then set up a nice contrast to what we believe the current GT3 Cup and GT3 Rs have been running and what we think the RSR will be running.

I am with you. Just sharing what was shared in my car group. We need to take all rumors / predictions with a grain of salt

"We learn a lot from racing, said Dr. Walliser. "It gives you a good feeling if you say, 'this engine raced in the 24 Hours of Daytona, and nothing happened'"

Novel concept. Wish they'd done it with the current motor....

Just in time

True. The GT Daytonas all ran the 24 Rolex with no engine failures. Now that's only 24 hours!

RSR

Any part with an "R" designation is a motorsports part.

Where is the documentation for 11.5k rpm? That's a screamer

The engine in the GT3 will not be copy of the RSR. A derivative maybe...but not a copy.

If not for the least reason that the engine in the RSR has a rigid valve drive whereas the GT3 has a variable valve control system for better torque management, emissions, etc.

I have been reluctant to talk about this as I am not sure that my info is true and I only like to make statements about future stuff when I know it to be really, really solid. I think I was the first to mention the 4.0l, manual option, etc back in March because I knew it was on the money.

More recently, I heard that the wing delete will only be allowed with the manual because it requires a diffuser which will not fit properly with the PDK. Something to do with not enough space because the 6spd box is different to the 7spd PDK.

But don't take this as read, I am trying to verify thru other sources. I am a bit doubtful.

STG

This would make perfect sense. Will be the same as the R diffuser and just a .2 version of it pretty much.

I think you could be correct.

Thank you Chris. Does your source say that equipping of MT will automatically delete wing as posted by ksas contact , or just that the delete is optional only on Mt cars?
