<p>SuperFlow data files for the 2005 Fusion</p><p>05fus3.sfd 05fus4.sfd 05fus5.sfd 04fus8.sfd</p><p>Test 4 is all stock, air intake as delivered, our airflow meter duct taped to the quiet box inlet.</p><p>Test 3 is with the massive air intake box removed, airflow meter duct taped to the opening in the throttle body airbox next to the tuned pipe/ y pipe. Note that airflow CFM is much higher, fuel flow lb/hr is stock but that = excessively lean mixture! We have some glitch in our dyno programming—for this test we have plumbed the fuel pump feed line through the A fuel turbine, then plumbed the bypass fuel flow through the B fuel turbine before it’s returned to tank, the dyno has a “Fuel A minus Fuel B” switch for this situation. So though our fuel flow lb/hr is correct, for some reason the BSFC and A/F ratio is still based upon Fuel A flow ( about 240 lb/hr) so it’s useless. I need to get Sean Ray or Carl McQuillen to help me with this glitch (Carl stopped by today and fixed my erroneous date/ time for storing and printing tests) So I have included a column for “air density lb/cu ft”. A/F ratio is based upon lb of fuel vs lb/air. So to illustrate, looking at the test with airbox top removed, and mentally smoothing the fuel flow numbers, we have about 102 lb/hr fuel flow at peak HP. 320 CFM x .075 lb/cu ft = 24 lb of air per minute x 60 = 1440 lb of air/hour / 102 lb of fuel/ hour = 14.11-1 A/F ratio much leaner than the 12.5-13-1 that will usually create maximum HP on our dyno!</p><p>Doing the same math with the stock air inlet fitted, we’re looking at about 11-1 bone stock—not bad compared to the early F7’s 10-1 there may be HP adding airflow left on the table! What Bill and I will try to do tomorrow is tweak that stock airbox a bit to add 10% to airflow—with fixed fuel flow that might put us close to 150 HP. As long as the deto protection is there, why not? We’ll know more tomorrow. </p><p>And now tomorrow’s (Sunday’s) important SFD files are here too. </p>
