driving fast (what's the fastest you've gone in a car)

Re: 9500 rpm in a NASCAR engine- it's all about reciprocating mass-
if you have light enough pistons, rods, valves and strong enough
valvetrain
and fasteners, it can be done. Aren't those engines using Ti valves and
valve
springs? No black magic there- now when you talk about 1500hp out of a
1.5L turbo V-6 with 60psig of boost, that to me is black magic.
