An update on the LHU project. We have decided to use a straight stick bell housing to mount a belt drive reduction to. That means that we could use a clutch to disingage the prop. ??????. Using the bell housing will cut the cost of having a thick spacer made. We needed at least 4 inches to clear the water/oil cooler. We are trying to keep the cost down to make an affordable airboat that performs good so we selected the new 2.4L Ecotec for these boats. The new Belt Drive reduction will bolt to either engine. We purchased 2 new 2.4's and sent one to the CNC shop that is designing our reduction. The other one is here at the shop and we got the ECM for it. The engine wiring harness should be in tomorrow. We don't have the ECM for the LHU engine but the wiring harness for the LHU looks like it matches the connections on the LAF ECM. Are these 2010 and 2011 ECM's the Same? We have the new manuals fo the LAF but want have them for the LHU until after Aug. 20th.
We hope to get about 330 HP with the LHU on E-85 and maybe 220 HP with the 2.4L LAF on 93 octane E-10. What do yall think?
Thanks, Chuck
Hey Baron, if i gave my source, i would not be able to sell these engines. We can sell the LHU with Turbo for $ 3900.00. The engine wiring harness is not included.
I haven't been on the site for awhile. Been studying the wiring on the LHU and LAF. For the 2011 models they both have to have a Fuel pump Control Module and a fuel pressure sensor. The LHU also has to have a Fuel Composision Sensor that fits into the fuel feed hose. The ECM's look the same for the LHU and the LAF. I hope they will work for either engine. We now have the Service Manuals for the 2011 Buick Regal and the 2011 Equinox/Terrain. We bought a 26 gal fuel tank from a 1500 chevy truck and the Equinox fuel pump fit it perfect. By using the truck fuel tank, it will make it easy to hook the EVAP so we can try to get this boat EPA certified. I will be posting pictures soon.
Thanks, Chuck
^^^ all of those things are epic, I only ask because I have a 68 mustang That I want to have 300+whp and 30+ mpg. The new 5.0 coyote could do that in the car that only weighs 2900lbs, or a gm turbo four bangor could also do it, (coyote motor is 8k with wiring harness, than I gotta redo the front suspension to make it fit so probably like 12k) or an LNF LHU would be 4k~ new (or much less junkyard/used) and fab up something to make it fit a t5 or tko.....
We are still waiting on a few parts to be made to mount the reduction. We will use a 1 inch adapter to bolt the reduction unit on. We are re-making the thermastat housing so it will clear the gearbox.
We have also purchased a 5 cylinder LLR engine that we want to put on a boat. I have to get an adapter made for it but can't find a cad drawing of the rear of the engine. Does anyone know a site i can go to for the drawing?
Thanks, Chuck
We are starting to make some progress and decided to set up an engine stand to run the engines before we put them on the Metalworks. This one will get the cat and EVAP system so we can try to get it EPA certified. Here is where we are now.
We are working on building a belt drive and using a stock bell Housing. I was thinking of using a clutch and pressure plate and we could disengage the prop if we wanted to. I didn't want to buy new parts and maybe not use them. Does anyone have a wornout clutch and pressure plate i could get for mockup. I already have a flywheel. If so, i could get UPS to pick it up.
Thanks, Chuck
Hey Maven, can you come up with the bell housing drawings for the 3.7L Atlas 5 cylinder engine. I have to get an adaptor made for it too.
Thanks, Chuck
We are making some progress on the engines. We had to get a 2.4L ready for a customer so we slowed down on the 2.0L Turbo. Here is a video of the 2.4 running on a test stand.
We only have one thing to work out. The rev limit stops the engine at 3930 RPM. We think it is the Park/Neu rev limit. We don't have a transmission module to tune and Vince is trying to work around it while i go back thru the wiring to find a way to control it. What do the members think?
Thanks, Chuck
