ECU for 14k rpm V8

The limit for F1 engines is 3 liters in capacity and 10 cylinders per engine.
They're naturally-aspirated, whereas I believe CART cars are 
twin-turbocharged V8s.

Most of the F1 engines redline around 18,000rpm, though I believe Mercedes
are working on a new engine which may surpass 20,000rpm. For the current
Mercedes engine, it's 2998cc with a bore of 91.00mm and a stroke of 46.09mm.
It's a 72-degree layout, incidentally. The most common layouts are 72 and
90 degrees, though Renault are working on a 111-degree layout, but are having
problems with vibration and rigidity

Interestingly, F1 engines used to be very small-capacity (this is going back
a decade or two), with less cylinders but with turbocharging. There was a
particular BMW engine that was, I thinkm 1.5 liters in displacment, was in
a V-6 configuration and pumped out some 1,200bhp in qualifying trim. I think
it was running about 4 bar of boost pressure, though.. I'm told it could
wheelspin the entire way down the track in top gear if one were so inclined.
I believe that the FIA later limited turbo boost levels to 3 bars or so, and
later outlawed it altogether. They were truly amazing things, though..
