let me know...


Thanks.

 

Nobody here with JUN cams on their EVO X ?????????????

 

Wondering the same thing, sorry to bring back a dead thread but maybe now some one has these on their car

 

Yep right here. Jun 272 and springs. Awesome cams but they are man sized. Don't even think about idling them at less than 1000 RPM. They are much larger than your typical 272 cams. I suspect different manufacturers measure the duration at different lift numbers. Anyway, they do require quite extensive massaging of the MIVEC maps. If you have any major changes under vacuum you'll see some drastic changes in AFR's and some stumbling so maps will look COMPLETELY different than stock.

 

^^^^Very True^^^^

 

Hi guys, does anyone by any chance have the full cams specification for Jun 272 evo x?
