Dyno test 2 used the Camshaft...
Dyno test 2 used the Camshaft Innovations mechanical flat-tappet cam with a steeper 1.7:1 rocker ratio and the suggested 0.016-inch lash. This stout rocker ratio accelerates the valve very quickly, which means it might float the valves sooner than a 1.6:1 ratio, but that extra lift definitely pumped the torque and horsepower all the way to 6,500 rpm.
Westech's Steve Brul commented that with a few more tweaks, such as experimenting with lash and some lightweight synthetic race oil, we might be able to squeak 485 hp out of this combination. Of course, that's like dangling a carrot in front of a donkey, and now we're thinking about what it would take to push this budget Mouse up to 500 hp. But even at 475 hp for less than $4,750, it's hard to find fault with either the power or the price.
