Guest |297| Posted April 30, 2009 Report Share Posted April 30, 2009 We have purchased a land and sea dyno that couples directly to the jetpump. The dyno itself is just a waterbrake controlled by a computer controlled auto load valve. On the water brake is a strain gauge which meausre the flex on the mounting plate, from that Hp and torque are calculated. Using the load valve we can tune any load point at any given RPM it holds it perfectly. Best tool we have ever purchased as the engine remains inside the hull and we can thouroughly test air intake systems, exhaust systems to get a true performance indication.
