I don't see the pipes for your inlet air from your turbos. it looks very nice but I don't think it will make boost like that.

BigSilverCat 04-10-2010 02:52 AM

the intercooler mounts to the boat, so we will not be able to show the pipes till its in the boat. (or maybe we are pressureizing the whole engine compartment.)

the air comes out of the turbo and goes through the pipe that is behind the ignition coils that hugs the back and side of the block and goes under the oil pan towards the front.

Tyson is that your last name... Smith.. looks great.

mcoutlaw 04-10-2010 08:12 AM

Some more nice work from Brad and Tyson. What kind of HP are you looking for and of course what boat they going in?

cougarman 04-10-2010 09:43 AM

The pictures don't do them justice, I had the pics on my computer for a little while but did not put them on here because they definately don't look as good in a pic as they do in person.

That things gonna be a rocket!

What drives?

Comanche3Six 04-10-2010 11:30 AM

Easily the most beautiful marine powerplant! Looking forward to see how it runs.........a great thread!

thanks, there is about six months of work in these, there is alot of stuff that takes along time to design and build that you cannot even see in the pictures. The last several months brad worked on these till 1 am every night. And I have several allnighters machining parts for them.
We will update this thread as we dyno them and put videos on here.

Tyson,

Did you ever add the pictures on the other thread you had started with the Injectors on the inside? First couple pictures you had posted you were about 75% complete.

Be great to see them if you have them, are you spraying the top side of the runner?

Thanks again,.........Pictures still look great even if they are better in person.

You and Brad look like you have something going good here. You should name it Smith and Garvin Motorsports or some such.

Tyson post pics of that red 47 cat you're going to build(hopefully). I think the guys would like to see that.

I just showed someone that video this morning, it's amazing the volume of air stored in an intercooler at 30 psi

Jassman 04-10-2010 05:37 PM

Great job, looks awesome, alot of detail..add some kick azz trannies..and now all you have to do is design a drive..:drink:

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!!!!

BigSilverCat 04-10-2010 10:19 PM

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.

Well what's the #'s NA?? :angry-smiley-038:

BigSilverCat 04-11-2010 05:16 PM

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.

masher44 04-11-2010 10:21 PM

Awesome!!!!!!!!!!!

bigo181979 04-11-2010 10:40 PM

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.

Great work as always Brad and Tyson.
O yea my SMITH POWER ran Great this weekend!!!

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
