He was out accelerating you because he had more torque at a lower RMP... You had to spin up 3000 more RPM and you still didn't have as much torque... On a tight track, his motor is a much better choce... You'd have to gear higher to match him, havng equal rollout definitely gave him the advantage... You'd have been better off with a ratio over 9.2 to take advantage of the added RPM.... In my eyes your motor's numbers weren't better than his, I'd have used his in a heartbeat...
Did you stay with the same rollout? Your second motor was definitely better, there was only a 1000 RPM gap and from what you posted you had a slightly higher rollout to take advantage of it...
The dyno read fine, it was more like you didn't see the whole picture...
my sorry 20,000.
he had more torque then my 1st motor but my point was that both motors had good numbers.
just different.bcause one had hi torque and the other higher rpm.
so it all depends on the track conditions etc.
