Shafiroff Racing dynos HILBORN injected 509

As one of the most recognizable names in high performance crate and custom engines, Shafiroff Racing (800.295.7142) needs no introduction.  After many years of design and testing engines of all types, they turned their skills to the hot rod market designing an all-aluminum 509 cid W-engine. This engine not only looks the part but has plenty of power which has only been enhanced by the HILBORN injection.

“We picked up an extra 50 lb-ft of torque and maybe 15 horsepower,” says Scott Shafiroff. “Same cam, same head.” exclaimed owner Scott Shafiroff in an Engine Labs article about his successful dyno experience with the HILBORN. Click here to see the Engine Labs article.

The below dyno test was using a complete HILBORN EFI-R kit with Holley HP ECU and a Weldon Racing fuel system.  Shafiroff Racing has other engine models available with HILBORN Injection. Give them a call to discus your needs (800.295.7142).
