    Slowing down in the heat

    Is anybody's ski slowing down in the heat and humidity? After installing the wedge and exhaust mod, I have not run anywhere near my best speed of 67.6 (ran that several times) The most I have gotten out of it since the mods is 66. I ran the higher speeds when the air temp was in the upper 60's with low humidity. Saturday, it was 92 and humid. The ski felt like it didn't want to pull past about 7650 or so. When i ran 67.6 the rpm's were 7820-7870

    Cool fresh air from the outside needs to get in the hull!

    Outside air is much cooler than the air inside the hull

    I've noticed that has it get hotter and the air is less dense the boost readings I am getting on my digital boost gauge with memory are continuing to get lower and lower. Yesterday the highest it recorded was 11.1.,but it was in the 10.7-10.9 most of the day. I was getting 11.5-11.7 on average in the cool.

    How's it going on your intake? Got any info or pics you can share with us. That's my next mod but I'm undecided as to which way I'll go.

    I will be forcing it in with inline bilge blowers. Your local muffler shop that has a flanger should be able to produce a stainless coupler from 3" to the estimated 2.5" thru hull connectors.

    No kidding........ I was refering to the fact that heat and humidity will slow these skis down if you have a fresh air intake or not.

    You're always gonna run slower in the heat on any ski. It's something you'll have to learn to live with. Thats why most of the top speeds posted here are from the winter / spring weather.
