I don't really care what the end number is, or what anyone thinks their end number is, or what anyone thinks is thoeretically (technically, practically, religiously) possible. I haven't mentioned what horsepower I think it'll be, because I don't need to quantify it. To quote @550 Phil, "it sings to 7500 rpms at a flick of the throttle in any gear. It’s very fast." I'm getting pretty much the same motor and I expect it'll do all that without needing valve adjustments every 3,000 miles.
I've raced bikes with a power to weight ratio no car I can afford will ever approach, so I have a pretty good idea how deep the water can get. I have full control of my right foot and my faculties, AKA I can swim well enough. To quote one of our favorite citizens, I'm doing me. These cars a great fun, that's a large part of the point. It's no skin off my nose if someone wants to claim 200 ponies. That's them doing them.
