Sweet looking package. How are you getting the wring to the injectors that are inside of the intake. Do you think there will be any issues with the wiring and injectors being inside of the intake. You have to be anxious to see it all finished and in the boat. Keep the post going until you get it in the water!!!!

The wire Was potted in a fitting that is screwed into the bottom of the intake so it is airtight, the wire and injectors will be fine being in the intake unless it backfires, it's computer contolled so it should not be able to backfire. but the wire is cl3 rated for fire so it should be fine.

We already have several hours of run time on them on the dyno naturally aspirated because we wanted to see what we could get naturally aspirated first.

840 hp
but we did not turn them high rpm because it doesn't matter what it made we just wanted to have a base line to start with.

I have always loved turbo motors, the way the build power, and the ability to make more power then supercharged motors due to no parasitic losses... I have always wondered why no one has really used them in high perf marine applications... Great to see someone going out and putting in the work!!! Can't wait to see how this all comes out.

There are three 1200hp twin turbo Chief motors in a 47' Apache and I'm sure Tommy has sold more than those. He says his electronics have solved the turbo lag issues common to V8 turbo motors. Six cylinder motors such as Cummins and Yanmar don't have lag because the turbos can be stacked.

Tyson,

How much boost do you plan to run?
And do you have concerns of the boost blowing the potted fitting out?


Thanks
Jon

we are running 8 lbs boost on the pump gas setting and 15 lbs boost on the race gas setting. Then for the shootout we will try to break the needle off the boost gauge.

We machined a step inside the fitting so the potting material cannot be pushed out, it should handle more then 100 psi and I don't want to be in the boat if it ever goes that high
