I belive the KA is geared to 155mph 5th gear at 7000 or was it 7200
I know how displacement affects revs. But Money fixes that problem. Just like the KA24DE's that hit 10k rpms
Here are a few pics of one. Single gear. Spinning tires at 100mph at the track. (Enginge only shots at his garage)
But he ran a high comp stock bearing/rod/pistons(3 valve) And rev it to 8k all day long no problem.
I'm just following this guy and what he's done.
