Fact: WEC, F1, and Indy Car are all turbo hybrid.....and that little regional series is still pushrod 8s....even when you could attach a spec hybrid unit onto the existing piece....still can't get it done, but you can be assured that they want to. Can't wait for the next manufacturer.......but it will be some time....the traditionalists will **** themselves, jump in their hybrid trucks, and go home. FYI....WE have turbo hybrid 4s, 6s, and soon 8s. If NASCAR could get their heads out of their asses, WE could flip the script on that little lack of pushrod 8 upon our entry which is so frequently mentioned. Fingers crossed, but cramping.
