Callaway twin turbo research Corvette

waaay, back in 1988 the Callaway Sledgehammer was driven from Connecticut to Ohio, hit the track and after a bit of tuning was clocked at 255rmph driven by John Lingenfelter.. who got out of the Callaway and got into his Corvette to go home, and said "You know, that goes 100 mph faster than mine?"

Watching the video will show you how they got all that into the engine bay, I was most impressed with their method of cutting out frame, patching it into the air system, and them reinstalling the piece of frame, with outputs to the turbos
