I was wondering the same thing. Just got back on FacePlant in the last month and follow a few Offshore sites but even their participation is almost nil

LB4, That`s some great power and I`ve always loved a dual blower set up!

How much boost in the boat?

The engines were supposed to be 1300hp+ before I picked up the build, 380cnc heads flow a lot of air.I told Eddie slow that down as much as possible, Top speed will be plenty, I`d rather have less power and more reliability but Eddie can only slow things down so much before fuel distribution goes to $hit so he`s thinking 1100HP is about the lowest he can go.
Good luck on your project! It`s going to be a rocket!

Currently just messing around with stuff,
I would rather not put in the interior until the engines are in.

Air Horn of course,
More lighting, trailer and boat.
Quick disconnect and new steering wheel.
Seperate pickups and strainer for intercoolers.
Just keeping busy lol

I really like the bluetooth operated swiches. My drives are on the throttles but I want tabs to be easy to control without having to let go of the wheel.

CP did not have a bracket for this style steering so Mike at CP made a bracket.. that should be pretty cool .

I went down to eddie and picked up a bunch of stuff to be powdercoater/annodized and polished.. those finally went down last friday..apperantly whatever Whipple uses for powdercoat is hard as hell and not fun to strip.

Drilling big holes in a freshly painted boat, pucker factor is high.........

I told the dyno shop the boost will be 14 lbs, they said Wow we don't think so and on 91 octane, Really. It turned out to be 14@6500 rpm. It will top out at 15 Max @7200. Funny but there is a double intercooler stack on these 570's total 3 intercooler cores. Intake manifold temp during pulls was 105-107. With the ambient temp at 92 that is a 13 degree rise and Great to keep octane numbers down. So think I can get away with 95-96 Octane. 1/2 oz of Boostane per gallon will do it.



Well a 3.3 Whipple is only good for about 900hp a 4.0 for 1100hp, 4.5 for 1300. It is a factor of total CFM flow as well as PSI and they can only spin so fast. 1100 would be good for a single 4.0 Whipple without stressing the package too much.

380 heads are nice size Mine are 375. As long as the RPMs are over 3200-3500 with some boost there is enough air/fuel flow. The bottom of the limit for these bigger heads. Torque numbers will prove that.

Transon is the original paint.

I also don't respond much to avoid clogging up nice build threads. Keep the updates coming, your builds are amazing and your pics and posts are enjoyable to see.

Seen it happen on a new Merc 600. Quite the mess.

Where are you mounting those air horns to get the sound outside? Just curious. Like the idea of some big horn sounds for getting the dumbass' attention!
