hmmm, it's kinda hard to say. My boy, ( SpeedyMon ) dynoed at somewhere around 170 or so, and he had a best E.T of 14.00 untuned at around the same boost on a GS-R with stock internals. He is running the Drag3 kit, and was running 17's at the time. Soo, I don't know. I'm not much into these F/I numbers so this is all I know. ( I'm up shyt Kreek when get this GReedy Turbo kit.)
