this just in, Just ran the pipe without tune . 389hp
I will get a video of it .
This thing is a V6 Grand National With a Turbo the size of a jet engine. It just made 1600 hp on the Dyno. Stupid power! Power per Liter @ 4.3L ( could be 3.8 ) = 372 HP .
What I'm shooting for in my Kaw is power per liter = 377. That goal seems almost doable now. Kaw = DOHC That monster above still has push rods and is making 1600.
