Fast forward to 2013, and conversations with American Mechanical Engineer and racer – Patrick Hale, convinced Greg there was a more accurate way to tune these engines. Patrick has devised a method of tuning that compensates the weather correction calculations to take into account the tremendous cooling effect of methanol injected into the air entering the injector hat. This cooling effect changes the air density.

The ambient conditions measured in the pits are NOT the same as the air that enters the supercharger, and failing to account for this results in a less-than-perfect result. With the aid of Software Engineer Greg Leach (who also compiled the original software some 25 years ago), we have written a program incorporating the “Methanol Correction” method, along with some further refinements, which we believe will tune a Blown Alcohol engine more accurately and consistently than anything previously available.

Alky Pro accuracy and future development is backed by a sophisticated Fuel Injection Flow Bench – using multiple Macnaught oval gear flow-meters, an adjustable pressure chamber to simulate manifold boost, and RacePak data logging. We have spent hundreds of hours testing individual components – nozzles, jets, fittings and hoses, barrel valves, fuel pumps, etc as well as complete fuel systems for a variety of engine and blower combinations (Roots and Screw) in order to confirm the accuracy of Alky Pro software. We use pure methanol as the flow medium to ensure accuracy*.
