well i started breaking in the new grenade today and after some minor issues me and my good buddy zixxer got it running. it purred like a kitten for most of 2 tanks at idle (which seems like a month btw). temps were very predictable he was breaking in his new grp and i was doing the grenade we were predicting the temps before we hit the head with the temp gun and we were spot on most of the day. that grp is looking like it will be one heck of a motor but the grenade honestly looked just as good
. i hope it continues to.
