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.
