2. Show 9000 RPM Results Many Blown Alcohol engines are using higher engine RPM than ever before and the existing standard of flow at 8000 RPM has become obsolete for some racers as their revs don t drop to 8000 RPM on the shift into high gear Selecting this option will display a second box and display flow and fuel pressure at both 8000 and 9000 RPM for the following items e Boost e Fuel Pressure e Pump Flow e Target Flow e Current Flow e Loop Flow This secondary set of results can be set from 9000 to 10000 RPM in 200 RPM increments by going to Settings gt Preferences in the top menu Weather Temperature Input of the current ambient Temperature Units can be selected in F or C and the program will automatically convert the current input when changing from one unit to another Barometric Pressure Input of the current ambient Barometric Pressure Units can be selected in inHg mmHg or hPa and the program will automatically convert the current input when changing from one unit to another Note It is important that actual or absolute Barometric Pressure is used not corrected Barometric Pressure Altimeter If you are using an Altimeter rather than a Barometer you can change the Barometric Pressure units to feet and the program will change to Altimeter input mode Please note that the barometric pressure dial of your Altimeter should always be set to 29 92 inHg to ensure accurate pressure
3. Flow Bench It is best that the Pump be tested at a pressure that is indicative of the pressure your system has at 8000 engine RPM in High Gear Fuel Pumps should be checked periodically to ensure they remain within spec Target Flow This number is the basis for all Alky Pro calculations and corrections It is the volume of fuel that you want your system to flow to the engine at 1500 feet Corrected Altitude in High Gear This is as close to an Industry Standard for Blown Alcohol fueling as we have The beauty of basing our jetting on this number is that we can richen or lean the system by a known amount with the click of a button in response to performance track conditions data or physical evidence spark plugs bearings etc The increment buttons will move the Target Flow up or down in steps of 0 1 one tenth of a Gallon Per Minute with each click or you can input a number via keyboard This means if you wish to richen or lean your system at any time for any reason you can increment the Target Fuel number and the necessary jet change will be instantly reflected in the Main Jet field Where do you get an initial Target Flow If you are currently running your car successfully you can use a Target Flow number that will return a Main Jet size that matches your previous setup from a best run Just be sure that you also input the correct Weather Data at the time of that run so that the Main Jet recommended is under the same conditio

12. n Grains sometimes called Absolute Humidity tells us how much water is actually in the air so in many ways it s a more useful measure Suppose someone tells you they have a container that s half full of water You know that the container is 50 water but without knowing the size of the container you still have no idea how much water is in the container Knowing you have 50 of an unknown amount is a bit like Relative Humidity while Grains is like actually knowing how much water is in the container So how does knowing Water Grains help us Well there s really no definitive answer What we do know from racer experience is that when Water Grains are high somewhere between 60 and 80 plus it will have a negative effect on engine output A high Water Grains reading can t be dealt with by making a jetting change as the humidity is already fully accounted for in the air density corrected altitude calculations High water content in the air affects engine efficiency in several ways but the major effect appears to be the slowing of combustion speed so it s possible that an increase in ignition timing may help when we see a high Water Grains reading Other changes to the cars setup consistent with less power may also help Specific Gravity Correction The density of the fuel we use varies with temperature When the fuel is colder it s denser and we need to inject slightly less of it to make the same power and vice versa when it s

15. r software or possibly a spreadsheet if it s sophisticated enough to calculate pressure differentials properly If you set your fuel system up and test it alongside your previous method it should repeat very closely when set to Conventional Correction mode Methanol This mode uses a new method of calculating air density based on the pioneering work of Patrick Hale dragracingpro com which incorporates the large cooling effect of methanol evaporation that occurs BEFORE the inlet air enters the supercharger rotors If you ve ever wondered why your car doesn t always perform the same on different days or different tracks or why it occasionally hurts parts even though you ve jetted it correctly according to your current method we believe this new method is the answer The air that enters your supercharger rotors is NOT the same as the air you re measuring in the pits or staging lane Page 4 If the change in air density that results from injecting methanol into the air before the rotors were consistent we wouldn t have to worry about it Unfortunately it is highly variable depending on ambient temperature and humidity So if we want really accurate jetting we need to account for this effect Using the Conventional method means that on some days your engine may be a little richer than you intended down on power but safe Other days you may be a little leaner than you expected and we all know the result of that if your tune up
