IIRC you are not going to have time to dyno these engines are you? That's a bummer! I'd love to see what you and Mark could squeeze out of them on the engine dyno while monitoring cylinder pressures.

Regardless, thanks for sharing even when I may not say so with every date! It's fun to see this project come together.

Times got pushed a couple weeks due to cranks. But we still plan on having them together in 2 weeks. All the long block pieces for one are ready, only missing a medium duty oil pan an rear cover for the second engine if anyone has those taking up space.

My Mr Goodwrech partner / engine builder is on vacation this week. I'll be out of town most of next week. But all the aluminum pieces are in powder coating, injectors on order, flywheels being cut, and headers should be ready any day. Only missing the CP3, some turbos, and a good 20hrs worth of custom wiring harnesses.

They will both still run on a dyno prior to installation.

Before sending it out to powder coating, I did a quick mock up with one of the Banks intake to get some measurements. While certainly not for everyone due to it's 80gpm water requirement, I do really like the design and time someone spent laying out these molds. Rather than color coat the whole thing, I'm gonna see how it looks leaving the intake runners raw for now.

My goodness there's a lot of cubic dollars right there. Someone has an entire money forest, not just a tree.

...amazing that we all think WE are bad at spending money on our trucks. Not a drop in the bucket compared to this.

Hahahaha...:hug:

Y'all have no idea what the elite spend on their boats! Lol...

I can't post pics of 99% of what I of what I work on but it's nuts what people spend on boats, I have 1 customer who's son (he is 21, and one of the coolest kids I've ever met) has over 3 million in boats and his own tackle shop. Another's has 55 million in jets, 2 in helicopters and 1.8 million in boats and that's just 2 customers of over 500. Granted, I live in a very special place...:angel:

Not polished yet either... :D

Actually a better deal than I was originally told by the guy who had that set on the Wagler engine displayed at PRI. Those cost me exactly same as the custom set I built in house a few months back, minus up pipes. I have to build the up pipes in house with T4 mounts now. So, Break Out Another Thousand..

316L mandrel bends run about $50 each, looking at 8 per pipe. Each manifold has about a grand in raw stainless. But for salt water, there is no substitutes if you expect them to last 10yrs or more.

What do you use for gauges? Anyway to convert to NEMA 2000 protocol and display the data on NEMA compatible displays? Or better yet use the J1939 can bus connection on the new Garmin units? That would help with integration and monitoring, I have used it on a few installs with cats and have no issues to date...

Those are sexy right there...

Stainless marine?

CMI.. Same corp umbrella as Livorsi now. Who's also doing the Dmax electronic throttles and all the N2k gauges for this build.

And your right about the jack spent on performance boats.. Example, a twin turbo 1100hp QC4v Mercury Racing engine is over 120k without the out drive. Looking at 170k per side in those bad ass cats you see on tilt trailers that cost 100k alone.

I'm well under that base price for "2" 1000hp Dmax marine engines, and the drives I have are way cooler than anything Merc ever built. ;)

Picture of the drives, and what I pulled them off of... 50' Nor-Tech with two 1800hp turbines. This is just an old Baja, in a market where a new hull cost more than this boat will be finished.

Your having them build a shifter and throttle binical and not use the hot foot? :D

Livorsi has been building a throttle / shifter combo with GM TPS setup for Sweden Marine Diesel a year or two now. Plug and Play to the ECM.

On the NMEA gauge outputs, that one's all my work.. :thumb:

Ben is doing a cool dual DSP5 switch setup, and some twin MAF adapters for this build. So each turbo will have a MAF on it, but the ECM believes it's a single turbo engine..
