Was talking with Shoe on the sandbar last weekend about running the 10.00 class at Ming in Sept. He's telling me that to be even slightly competitive I will need a launch controller. O.K. What exactly is a launch controller and how does it work on a jetboat? At Elsinore I was launching on the spray and was not consistant at all on the tree.

It like a rev limiter, ramps up the rpms, in a given time period

It will really difficult to dial in a launch profile without a data system installed on the boat. I would work on getting that first and then step up to the launch controller otherwise your launch profile will just be a guess since you have no facts to as to how your entire boat is responding. Until then set your rev limiter to 200 rpm over your max rpm and go out and run it.

Get ahold of Fleetimus on the boards. He's got one in his boat...or did at one time.

Is this like a delay box(electronics) in NHRA?

MSD makes the launch controller ... MSD part number 75611

They go for around $250-$275 new

You install it and use a PC to set the launch's rpm curve within the controller to control your rpm's upon take off.

You'll need a full throttle microswitch and an "arming" switch on the dash.

Once you arm the launch control, it waits for the input from the full throttle switch to start the timed launch curve. You hammer it and the controller sets the rpm's during your take off.

As Ross said, it's harder to do without a data accusition system, but not impossible. It will just take more take off's to dial it against the tree. But it can be done.

Once they're dialed in, it's hard to beat off the line.

almost like a very basic dedenbear or biondo box, but with only one function

Pretty soon the boats won't even need a driver!

 

[bajadad]

Seems like it would keep the impeller from slipping under hard launch(big hp), correct me if im wrong....

is it against the rules to install remote control?

You are 100% right

 

[BUSBY]

you guys better stop ... one of these "new" and "untested" things couldn't work in a jet boat

no way ... no way at all ... sphss

 

[bajadad]

Totally makes sense, I like outside the box....

i knew harris was really controlling the boat at elsinore! lol

The boats do great. It's the driver that is always screwing things up!

This is what some of us use in the drag car scene, dont see why it would not work the same on a turbo boat set up.....I gues I have a shit load of testing to do!! sphss

Looks like a nice unit, I think with some testing it would work

spoken like a true ex-driver

If that's the case he would have one hell of a hole shot on the contents in the cooler.
