Plum there's hardly anything there compared to years ago. Thats bassboat country now but we have plenty of other places to run over here.

Kajun, knowing what Mike has in his boat and what I have in my Caddy boat, I think I would have done the same. Our boats perform the same overall (maybe his a little better) and he burns half the gas I do (at 87 octane compared to my 93).

Striker, I am hoping I can get my O 235 to run on 93. I just don't like the ethanol. If not, it will be a/v gas for sure. Hopefully, with the hull I am building, it will go where I need to go. I'm hoping it will run some dry. If not, I will be looking for a bigger power plant a little later on.

the push and performance of this boat feels as good as any good sbc.. if you didnt know what was behind you you would not know the difference !
the thrust to weight ratio is killer and well the gas milage speaks for itself .. i had ignored this engine for a while. but it has my attention now! i would never have thought a baby 4cyl would be capable of this. good engineering and a little turbo magic! 8)

For the GM stage 3 kit/ecm for the supercharged lsj ecotech it has a 50 dry shot programmed into it. Trifecta, the one who made the ecotec ecm standalone can also program the gm stage 3 parameters into the lsj as the gm performance ecu is locked and untuneable. With a turbo I would just tune for the max boost and then turn down the boost controller until you need it.

Please post the info for the available reductions for the ecotec, the power limits, and the max engine rpm. To anyone reading I did not forget the blade speed limits.

Main post updated with Thurst and Weight information. Max thrust @ 9.5 degrees pitch was 1145. Boat weight is 1700+ lbs without passengers or gear.

See original post for video.

Re: Ecotec progress (updated info: 3-1-2013 Thrust/Weight Da

Post by dantheairboatman » Fri Mar 01, 2013 9:51 pm

I guessed it Within 5 pounds. I said it felt like a small block now I see it's blowing like one that is incredible! If we can get this combination to blow 1252 1300 pounds of thrust that will be a killer combination. Not taking anything away from it now but I believe this Can be a reality. What impresses me even more is how heavy your boat is! I thought it was little on the heavy side but I didn't think it was that much. Makes me really want to try this combination on a lighter set up would be a blast! Still unbelievable to me that this is being achieved with 145 ci. Turbos certainly are wonderful..

I know deck height will not permit The larger diameter propeller but there will be a gain in thrust going from the current 76 inch diameter to 80 or 82. Just a thought.

Dan your butt dyno is very well calibrated :D

I'm pretty confident we'll see north of 1400 before this show is over!

We are making 3.85lb thrust/hp now. 1400 is "only" 363 hp. If we put some e85 in the tank and ran the turbo to 24psi, we'd be pretty close to that.

The factory 135 degree exhaust exist immediately after the turbine isn't exactly conducive to effecient flow either....might be 10-15 lurking there alone. Maybe we can figure out a way to modify the deck for longer blades too

The first person to strap a good aftermarket turbo on this engine and put it on a light setup is going to have a killer ride.

Let's see how close we can get to 1400 on the stock engine/turbo on 93 pump gas :toothy7:

my butt dyno likes the 235 gear better but it was interesting to see the over all gain in mid range thrust where you airboat the most by over pithing the max blades im with dan 6 more inches of prop disk will make what are already empressive thrust numbers go up and its a 120 ci wow.... i got to say that David Simpson has the eco grin now it is contagous .... had a great time and learned alot thanks Russ.....
