We pegged the 47 lb/hr port injectors when we went to E85. — Willie Diaz, MAK Performance
Making a leap from the 600-horsepower range well past 800 ponies obviously required some upgrades, but they weren’t as significant as you might imagine. The secret to release more power from MAK intercooled centrifugal supercharger was simply feed it a steady supply of E85!

“The only changes were the DeatschWerks 1,000cc injectors and DW400 fuel pump (PN 9-401-1001) with factory fuel pump hat modified by us and E85,” Willie explained. “We are still running the JMS FuelMax also. We pegged the 47 lb/hr port injectors when we went to E85.”
Obviously the ample fuel supply required some changes to the calibration as well, but what’s impressive is the new rear-wheel numbers were attained at the same 10-psi level as the previous gasoline-burning numbers, so there is likely still more on the table as the MAK crew keeps leaning on the latest Mustang.
