I posted yestersay on rev limiters for Thunderbolt 4 ignitions and got some good advice. now I need to know brand names and model numbers of limiters that are compatible with the tb4 and where is the best place to buy them. Also how much should I expect to pay for a pair?

I've got a MSD 8728 soft touch limiter I don't need anymore. Jegs has it for $94. I have it for $40.

BTW, the 8728 is the model that works with TB ignitions (inductive) but will not work with CD ignitions (MSD).

Brad is this a "marine part" or just a standard MSD product?

MSD does not make a marine only rev limiter. I have also used the 8728 with success on the Merc ingintions. Never had an issue with it. Brad's is a good price.

YES MSD does make a "Marine" rev limiter.....Call MSD. Don't run a non "Marine" rev-limiter. I just hooked mine up. This works as a stand-alone unit in addition to the stock ignition module. It is made to work with the thunderbolt ignition mods.....Look at MSD's web site or CP performance......Belive me the coast guard will check!!!! Seems like mine was about $125-$150......
