About 2 years to build as did everything ourselves. Does about 75-80mph at the moment. Still have to play around with the trim and jetunit intake to get it flying properly.m989 wrote:Awesome! How long did it take to build? Any idea what its top speed might be?
Yep that's correct as the jetunit doesn't really load up until 4000 rpm.Tofu wrote:Holy bejesus this thing is awesome!
Being in the water means the giant turbo isnt much of an issue with less resistance to the motor? (In regards to lag)
How do you cool it?jetboatkarl wrote:Motors get a hard time in a race boat as often you can run 20psi boost 5,800rpm for 30minutes without lifting off. Generates a lot of heat!
Raw water from the jet unit goes through a sandtrap (hydrocyclone) and then directly into the water pump, water leaves the head and goes overboard.Tofu wrote:How do you cool it?jetboatkarl wrote:Motors get a hard time in a race boat as often you can run 20psi boost 5,800rpm for 30minutes without lifting off.
