When I built my 2.0 liter, I was all set to go hydraulic. Adjusting the valves were a pita, and don't get the valve cover gasket right just once.......grrrrr. No one could talk me out of hydraulics because the only consistant, adamant argument against them was the loss in power. I'm an Aerospace engineer, and I wanted numbers, or to talk to someone that had actually tried them. If the loss was 5hp, or a 500rpm lower redline, so what? Then I talked to Dave at GRP. He had actually tried hydraulics in his car before it was a six. He hated it. His biggest problem was the awfull noise at startup. He made it sound like it was no small thing. Adjusting valves is still a pita, but i figure when I convert to a six, I'll use a 911 engine with hydrualics. Adjusting 12 valves must be a major pita. By the way, what was the first hydraulic 911 engine. The 3.2?
