Q for Ripp
Ripp Guys
Curious how you did the Timing part in your "Chip". The Fuel recipes in the world are so different brand-to-brand even Ch*^ron has a fudge factor of like 10% for X, 18% for Y, and 5% for Z ingredient.(not exact %'s but I could lookk at the MSDS again if needed) SO how can one predict fuel propagation with such a vast ingredient spread in Fuel. Not asking for any trade secrets just asking for a general idea as maybe I want one but am hung up on the timing thing.

Not to answer for Ripp or anything but most hydrocarbons (short of acetylene) burn at relatively similar speeds in spite of the composition of the gasoline. For a hydrocarbon generally a premixed laminar flame front propagates at 40 - 45 cm/s. The turbulence in the cylinder then wrinkles this laminar premixed flame front and increases the velocity high enough to allow the engine to fully burn the air/fuel charge before the next cycle.
