Re: can havasu heat kill speed ?
air density= less hp
hot air is less dense altitude less dense less air to compress affect torque |

How Many Before The Heat. What Is The Rpm Range For Peak Hp On A 496. Loosing 350 Rpm Is Normal In Extreme Heat. |
Re: can havasu heat kill speed ?
Turn around and go down river :eek: :D
Seriously though, there is also less density in the fresh water so your boat will lose speed in the fresh water too so that is another factor along with the heat. Jimbo :cool: |

Re: can havasu heat kill speed ?
10 MPH sounds like a lot. Early and late in the season I run in temps in the 50's, low humidity. Then July/Aug. temps are 90+, high humidity. Top speed difference is less than 5 MPH.

Re: can havasu heat kill speed ?
I have never seen more than about 2 or 3 mph difference in speed in 60 to 100 degree weather. I boat on Lake Norman, NC at 760FASL and run Ilmors. I actually can not tell the difference in heat. And we really have some high humidity.
I know that when I ran a blower motor I could really tell a difference. |
