i recently had the opportunity to meet a japanese tuning legend, hidenori yamakawa. mr.yamakawa has worked for central 20 tuning, was a lead designer for mazdaspeed and was also a consultant on the mazda 787b le mans car. this man knows rotaries like the back of his hand.

i was just wondering if anybody on this board has ever heard of him on?

 

Did you manage to ask him whether we shld use synthetic or mineral oil for rotaries??? :p

 

hes currently working on rotora's drift car for upcoming d1gp.

believe me....as soon as he has some free time i am going to extract all the knowledge he has on the 8.
