So now to track testing on an oval. I started with the peak power timing setting and everything was OK. as I backed down the timing and upped the roll out I got faster and the difference was noticeable on the straight. I settled on a spot 2 lines from the top for my motor. Our track was about a 145-155 runline and in the main I started with mid 3.9's but I finished still being able to run 4.0's. This setup shined from mid corner out as the bottom end grunt showed its stuff. One of those times where what you see on the dyno actually worked. Now I have to get this thing on the Motolyser to see what the real timing is.
