Interesting blurb on how modern sensors 'prove' just how powerful these engines are. I'd expect similar versions for gas powered street and hot rod engines. Heck, this kinda' stuff would be helpful to all classes of racing and even Jay's FE powered cars. Woo-hoo for modern stuff!

I wonder how they come up with a calibration?

Don't know but I'd suspect it's done by some type of calculation, maybe an algorithm using known acceleration rates from nitro cars.
That or actual dyno time on say a blown alky engine (some have done this, like Double AA Dale Armstrong long ago btw) and then extrapolating the hp curve for a nitro engine. All speculation on my part however!

These have been around for years. http://www.vericomcomputers.com/vc4000accelerometers.html

A couple decades ago in a Fueler power article in Hot Rod they detailed how the cams are ground 5, 10, 15 degrees off at each journal accordingly to make up for the crankshafts twisting under power ...............
Also amusing how long AA/__ was able to run 9" axle housings.
