      The Enderle Big and Ugly  and Upright   offers enough versatility to fit a diverse range of applications, from a low horsepower small block Chevy to 600+ cubic inches on E-85  . With that said, the BAU and Upright has become our go-to injector for the larger cubic inch applications especially on gas and E-85   In an EFI application, we can correctly lean out the fuel producing a tremendous amount of vacuum signal on the back side of the butterfly that can negatively affect throttle tip-in drivability. The BAU offers two distinct ways to reduce or eliminate the following tip-in issues.

      First, using the optional progressive linkage, we can completely shut the two secondary butterflies which entails opening the primary progressive butterfly farther thus creating a vacuum break. When one looks at a Bug or Bird Catcher for instance, all the butterflies are on a common shaft and as we close the butterflies to achieve an acceptable idle speed, these butterflies must remain slightly open. It is not uncommon for the engine pressure to bend the butterflies sucking them shut causing the engine to lose RPM. As the engine speed continues to slow, the pressure drops enough to allow the butterflies to pop back open where the engine regains RPM. This cycle continues creating a mechanically induced surge that cannot be eliminated. And in other instances, the butterflies can be completely sucked shut at the acceptable idle speed requiring extra foot pressure that pops the butterflies open resulting in an uncontrollable RPM surge. Regardless of which condition is experienced, throttle tip-in quality suffers dramatically. The vacuum break afforded by the open butterfly using the progressive linkage eliminates the sticking butterfly and the tip-in issues associated with it.

      Supercharged EFI applications from Alkydigger  Fuel Injection are used successfully in all kinds of applications from street to drag race applications. We have even proven our designs in the real life torture test known as Hot Rod Drag Week. Our hands on experience tuning and racing these same systems allow us to design a system for your application whether running gas, E85/E98 or methanol and with  sixteen injector nozzles. Feld Entertainment Uses this concept  on their Grave Digger Trucks and others,  testing  and field testing proved the concept allowing Feld to implement EFI on their fleet.

      Let us work with you to custom design an EFI system for your supercharged application.
