500 Bulldog rev limiter
Does anyone know if the over speed assembly or rev limiter, can be removed without causing issues with the ignition system on a 500 Bulldog engine. It has a Thunderbolt IV ignition on the engine and the engines are in a 99 Fountain 42 Lightning. Thanks in advance if anyone has any information on this.

I'm looking at the same thing- The newest style of the HP 500, the rev limiter is built into the ignition module, it's not a separate box. Is this also able to be bypassed? I'm referring to the set-up with the knock sensor. If not- is it possible to have this re programed for a higher limit.

I have wrote some timing maps on quite a few of these boxes. Even though I drive a truck, have no hands on experience with engines whatsover, specialize in google searches and reading magazines, the results have been good with those ignitions. For the price, considering they come with a good coil, they are are a good deal in my opinion, and very versatile.
The 500 Bulldog is a great candidate for a camshaft upgrade, with some additional rpm.

Thanks Joe, that is the system that I am looking to use. I also have considered using a DUI disributor as an option. Anyone have any thoughts on them? My only issue with the Daytona box is just figuring it out since I am an older person who does not get along good with modern technology. : ) I know some younger people that can figure it out for me if I get stumped. I quit drag racing last year because the class we ran in just got to complicated with all the computers.

They are pretty basic , especially if you want to run a simple pre programmed timing map . Data logging, 3d maps, can get a little more high tech though.
You can basically install it, select from the preprogrammed maps by turning a dial, set the rev limiter by turning a dial, and go. The nice feature is being able to use idle stabilization, which at idle, will bump timing to help maintain a minimum idle rpm, which is nice around the docks.

That is the way I am going to go. I see Barowski has them so that will be my next step. I have already upgraded the cam and everything else on the top ends so this will finish off the build for this year. (Hopefully)

The Daytona is basically the Crane HI-6M that is no longer available. I used that on my last boat and it is a very simple system to set up, and very reliable. When you consider everything that is packed into that box it's a pretty good deal. Most likely that is what I'm going to be using, with my new motors. It's a lot easier to just buy the Daytona box, than trying to hunt down a pair of V8-HP modules and then buy a set of rev limiters. If you do go with that set up, don't forget to buy the matching rotor for your mercury distributor.
