modded waterbox cooler temps results
went out today with Speedy. we were the only two boats on the water where we were i think. air was 80-83 lake was 83 820 elevation
i modded my stock waterbox like in the Tip Of The Day thread. (got anxious while waiting for the GREENHULK shorty box). i did not shorten any may do that later.
I also changed from the 82 to the 81 ring because of the lower air temp and the hope of some rpm gain with the modded box.
i redid the siicone on the intake grate holes and sanded the silicone smooth with a sanding block.
i also checked my sc slip while i had my waterbox out since i was and still only seeing 9.6 #'s of boost. it was 89 inch #'s so i left it be.
So anyway with three bars of fuel and me riding i went 79.2 the first thing right off the trailer. i then went several 78.8's several 79.0's and 79.1's and when i got down to two bars i saw 79.2 again even though i was not letting the thing cool down between runs. (my thermo mod and some more of the stuff i have done seems to help with the heat fade.
I am very pleased with these numbers and dont think that 80 will be very far away with a little bit cooler temps and my test pilot Speedy at the controls.
