Confused. I believe mine is V-8 and not the V-6? Did not the HP 500 come with V-8 module on Thunderbolt IV.

Thanks.

Thought the V8 HP ? was with the Merc factory rev limit like my Bulldog540. I can look when I get home. That's why I posted the link .

It was my understanding that all of the IV modules were advance only. Rev limiting needed to come from another box.

is this a twin application,

Lunatic Fringe 03-12-2019 05:45 PM

Yes, supercharged. I may try the v6-14s sometime this summer, but right now I just want to replace the bad existing one for the start of the year.

I just took this my power is a Bulldog 540

the link I posted is the number your looking for

Thr rev limiter is underneath the module

Thanks for the Pict. Crowley is listing it as unavailable, but there are a couple dealers they provided from a search that I will call.

Thanks
Jim

open87 03-12-2019 06:40 PM

Yes

That is Merc net which Crowley does as a courtesy which is great for regular people who don’t have access which is a nationwide locator.

Your welcome on the picture .

Thanks to all for the info.

Lunatic Fringe 04-18-2019 07:38 PM
