2,500 HP, 427ci Street-Strip LS Engine - Complete, Twin 83mm Bullseye NLX Turbochargers

This is a Drag & Drive type, full custom engine that can be built in a variety of configurations. It is still street capable, meaning it can operate on pump gas and it retains traditional head gaskets.  Its 3,000 hp rated, flex-fuel sister engine uses copper head gaskets with O-rings which can handle higher levels of boost.  Copper head gaskets however require frequent adjustments making them probematic for cars that see a lot of driving.  The major mechanical components of the two engines however are otherwise the same.  We modified the engine in the video below from street/strip to track-only in its second season (copper head gaskets, O-rings). It is this 3,000 hp rated version that is shown on the hub dyno. Our engine dyno is rated to 2,500 hp so we weren't able to run this engine up to the boost level it was designed to handle. The customer was able to get his Camaro onto ProSpeed's hub dyno and aired it out. Running 44 psi boost, he hit 2,737hp at the wheels as reported
