    Default 2015 Equipment Changes - 149 Tsunami BGJ

    November 29, 2014

    Hello People

    We are making some changes in the safety equipment on the 149 Tsunami.

    The old “mechanical Pop Off system” worked, but it would go off at the wrong time every now and then, when the pressure in the intake became greater than the supplied valve in the system, 150 psi is the static value.

    Well, the new system is being tested as we speak and it’s “electronically controlled”.
    The sample data shot is where RPM’s went down sharply and the intake pressure spiked very high, the q data recording shows intake spike went as high as 350 plus psi on this sudden de-acceleration.

    There are just some minor changes in how the driver activates and deactivates the system. The default circuit is set with the popoff open.

    The open set psi can be as high as the sensor being used to activate the system; I have mine set to auto open at 160 psi or greater

    Default ET improvements - Savings are being Planned

    November 30, 2014

    Hello People

    The 2014 race season was full of interesting data collecting and results from data history used to course tune the 149 Tsunami.
    After analyzing the data and timing slips we have concluded a weight saving program will help the program a lot, however is not necessary.

    The planned gains, loss is approximately 280lbs, which should show up very quickly in the time slips.

    What’s your take on the changes?

    Glad to see you making progress with your program Willis. The weight loss should certainly make it quicker as long as you can still keep it loading on the big end.

    No need to loss weight.just turn up the boost.

    Default Mechanical-Electrical Miersch PopOff Valve

    November 30, 2014

    Hello People

    The old Miersch system works and it looks like this.

    In 2013 I took the valve/system to Roy and he lighten up the valve and piston plus updated the manual override with an electrical switch.

    The electrical push button is on the steering wheel where the manual use to be.

    Default New Pop Off Valve Controls

    December 1, 2014

    Hello People

    The new Electronically Control PopOff System is installed. The system will sew up the loose ends in the emergency activation. The part of the old mechanical/pneumatic system I didn’t like was it would only load the psi value while holding the push in. The new system has a constant load while the 12v is present.

    When 12v is supplied the default is piston open, the operator has to load/arm piston down.

    If the valve is automatically tripped, the popoff piston will remain open until reset by the operator

    Hello People

    I’m making sure the slowdown process for 2015 is softer decent than 2014. The power level to run the 1000’ and win is very high for my program and It’s uncomfortable to me the way the boat is slowed down with the current process and power used / current equipment.

    Having,/ using less power and a lighter cart will be easier to slow and stay in the hunt for the win, 6.0 something.

    I would rather do it at a slower speed and quicker boat like K Adams said. . .

    Getting rid of that much weight is a lot Willis. Hope you can do it. I feel it's definitely safer to run quicker with less mph.

    Hello People

    The weight loss is a piece of cake for the first, 140, 18, and 23lbs

    The last is somewhat more creative without compromising strength for the hp / torque to pull the weight.

    I'm guessing 140 for an aluminum block and other components for 18 and 23. The remaining 100 in your equation will be a lot tougher to find as you've no doubt found already.

    Default Cool!

    Glad my dad could help you in your lightening process. Sounds like a fun project. What gains are you hoping for in lightening process?

    Willis the slower safer race strategy will require a boost controller of some type. In order to have more than one power level during the run. A - B run under the same power is 130's in any jet.
