Default GMG WC-GT2



There is a vision that one has when making a decision to take a factory built
sports car and making it a one of a kind. The proper resources and tooling
to take a car from A-Z need meticulous research and testing.

The GMG WC-GT2 package, also known as The Green Monster is
the embodiment of an owner's vision becoming reality through the
resources, knowledge, tooling and experience that comes with 10+
years in racing and aftermarket support with Porsches.

Look an interesting build- are you going to share more detail specifically the engine?

Great vid and lovely car. What looks like a 997GT2 intake manifold (at 00:53) unfortunately dictates that that engine will not be able to flow enough air for more than about 680 real FWHP. But that is a lot and the car will be fast.

Great build. That car looks impressive at every angle.

If you look carefully it looks to have a cable throttle. That gives me the impression that something else is going on there.

If the attention to detail in all of the other areas is anything to tell, I'm sure the engine was given equal attention.

I'ts rare to hear the number of 800 HP used, when typically its all about 1000+ HP or other insane numbers. This car shows details that it can stop and go around corner's too.

Yeah, I can see a funky bespoke looking plenum going on there, maybe that is not a 997GT2 intake manifold but it looks like 7GT2 runners and they cannot flow enough air for more than 680 FWHP and they are talking about 800WHP so 900FWHP .

Champion did some flow testing, GT2 flows worse than 997 turbo

I think you may be surprised at the performance the stock manifolds will produce. Who knows what was done to them. I think that if the rest of the car is any indication of design and input, I'm sure the engine received the same or more attention.

I don't think 900 BHP is impossible. I heard of a same size engine making 837 WHP at 0.9B boost using the same manifold.

I think the owner or friend of the owner is on this forum. He may chime in.

Wow! Absolutely beautiful. Can't imagine how much this build cost.

I don't think a company like this will share any info. Why should they. This was a special 1 off build by all accounts. The customer wanted something special and most probably wants to keep it to himself.

With the detail that has gone into this build, I cannot imagine the engine lacking HP. That would seem backwards, to spend huge amounts of $$ on the chassis and leave the engine wanting.

The attention to details is amazing.
