I hope the driver is able to recover completely. I was looking at a youtube video the other night of the Shadow cars, sans bodywork. I'm not a mechanical engineer, but the tub on those things just looked minimal in size and a bit fragile for my tastes.
I've had an interest in the Shadow cars for a while, particularly with the turbo Chevy big block. But for whatever reason, I can't seem to find much detail info on the engine setup. I would have liked to have seen a head to head matchup in the Can-Am series between the 917-30 and the turbo Shadow, but the Chevy engine guys just seemed to be a bit late for the turbo party. As much as I hate to say it, I don't think the turbo Chevy guys would have been able to match the durability of the Porsche engine at the time anyway.
