Any idea when this motor will be made available or when it will be sent to the APBA for approval??

It already is available and approved.

Thanks for the information. How does the 331 performance compare to previous models? Has anyone done testing with it?

Yamato UK site says it has less hp (32 vice 33), intention to reduce accidents occurring during turns in Japan arena https://www.yamatoeurope.co.uk/history

Also list some differences: https://www.yamatoeurope.co.uk/model-331

Curious to see if same cooling issues as 321 had...

Change out the tuner pipe to the 321/302 style and it will be identical
