side transfer duration
speed1 created the topic: side transfer duration
Hi Scott,
I have been following most of your threads and they are very helpfull.Thanks to you and other guys who helps a lot.
I'm modding a Zenoah at the moment and the side transfer duration is going to be 121.These are the other timings i will have in the mod:
squish :0.7
Exhaust duration:178
Exhaust to transfer blowdown:57
intake duration :155
I have to lower the intake port to 7.5 to get 155 intake duration.
What do you think about these readings?
Thanks in advance for any help.

For an oval duty engine with a broad HP & RPM range, see nothing wrong with those numbers.
