is the thread that has the info, there are also some ppl that have seen this car and seen it running on the dyno and track, and he says MTI Heads, not C5R, but then again who knows right?

But even if they are stock castings, I still have to wonder about the longevity. I'm sure RR could get a few dyno pulls for 1K or better (assuming the right turbo) before the radiator pressurized, right?

Well theres a big difference in the amount of boost between these two engines, which I didnt think of until right now.
Vette has 60 more cubic inches, with a set of what we can only assume to be hogged out high flowing heads and intake. Also the twin turbos are at lower boost. Which brings me to this question..
Using two T60 turbos at 13 would be moving the same air as a T120 at 26psi or no? I dont know enough about turbos to discern between their peak and potential, and all that. Hell I cant even understand a compressor map yet. so there must be something with that as well.

I need sleep, not just lay down close eyes and rest. I didnt even think that a gasket is a gasket no matter if its on a large or small bore! Damn. Now I know I need to read more when awake.

Two turbos will only have to flow half the volume of air as a big single to produce a given amount of pressure.
two T60 turbos at 13psi(manifold pressure) ≠T120 at 26psi
two T60 turbos at 13psi = T120 at 13psi (General statement again)

It made 792rwhp/904rwtq at 11.5:1 AF on 21lbs of boost. Maybe if I would have taken the 28x10.5W slicks off and put on some radials, I'd have gotten 8xxRWHP???
Oh well....going to bed.
