Well all seems good. She is running fine and no temp issues. My sughestion to all Hisen engine owners is to check the head bolt torque and make sure it is with specs. My mechanic found mine were not and caused the head gasket to blow. Now to figure out how to quiet here down which is my only complaint since day 1.
Well it's been supercharged for about 2 years now. If I remember right I hit 100hp on e85 around 4 psi at the dyno, went to a smaller pulley / cleaned up the tune and made over 150 at 6 psi that day. I've went even smaller since then and I'm hitting a little over 9 psi now.. Haven't been back to the dyno so current HP is unknown. I've broken axles and lots of u- joints but not the trans yet.. Most likely because my trans goes to diffs and not straight to the wheels.That and I don't launch it, knowing what I'm demanding from a "kei car" drive train. But now my regard for it's well being is gone with the k20 and 6 speed trans is waitin... LOL.
