That would sure be tough to do with a typical Cobra though. How are you going to tow it, or get it back to the pitts after a 1/4 mile run?  |
Easy on a dyno though. AFR could be measured and known, but the heat range and detonation indication could be handy. The big problem with this is aluminum heads. I wouldn't pull the plugs hot. Hmmm.
