Wow, just watched the videos on the 4.5l in the GT4, amazing power, everything I saw was about the 981 and the original 3.8l from that car, are they using a 3.8l and swapping out the 9A2 EVO for the 718 cars? Did Matt say why he chose a Spyder over the GT4?
No they have been using 9A2EVO motors to build 4.5s as well.
Given the Porsche ADM craziness, this Deman or BGB engines/setups together with a Manthey suspension/aero kit might be the ticket. Anyone know whether they are California smog-CARB legal given the new smog ECU/tuning rules?

Its an LA thing! Probably wants to tan his dome while he drives! Im sure he has other cars... plus the Spyder looks better, if only by a small margin. The only thing he was adamant about was the manual (he is even getting the 18ways and not the LWBS and probably the PCCBs) - he was even a bit 'touchy' on the subject of manual vs pdk wanting to only to buy Pcars without PDK... Thats fine... potatoes, patatoes whatever floats your boat.

No debate on the transmission, we all make our choices, not sure about the Frozen Berry , but as I have a MT, it was more a question if Deman was able to make that configuration strong enough to survive the new power output. No reason Porsche can't as well then.

Yes, always a cost but seriously if these are the pieces required it can't be that much especially at the manufacturing level... all the R&D is right there on the table, and the manual transmission is in!

I´m wondering if the current GT4 engine was already developed to handle 9000 RPM or they had to revise and add similar GT3 engine features such us (taken from christophorus):
The hydraulic valve clearance compensation, commonly used in series vehicles, is replaced with shims. They sit between the cams and the rocker arms and guarantee the requisite valve clearance, which no longer requires readjustment. Reduced surface pressures ensure a robust valve drive and enable maximum engine speeds of up to 9,000 rpm—ideal for meeting the challenge of driving on a racetrack.
Wider connecting rod bearings and larger-dimensioned main crankshaft bearings combined with weight-optimized titanium connecting rods can easily handle high peak loads and ensure extraordinary robustness
The central oil feed for the highly stressed connecting-rod bearing was taken straight from race cars—a technological detail already applied in the twelve-cylinder engine of the legendary Porsche 917. This elaborate solution allows maximum centrifugal forces and guarantees a reliable lubricating film, even at high engine speeds.
It would be nice if the 8000 RPM of spyder and GT4 were developed from the start to handle 9000rpm as-is , that would emply that we have a very strong engine...
PS: I don´t believe that the RS would have the GT3 engine as that would´ve been an impresive waste of R&D and the RS is all about maximizing ROI
