Re: ECOTEC 2.0 LTG SWAP

I guess I'll change them all out with some good grade 8 fastners. It's a 10 mm fastner....I thought 3 of them would have been plenty. I didn't think I could have over tightening it without striping threads in the aluminum block. That my friend is a classic fatigue failure, RAAJ is an Indian (not Ch...

Re: Pacemaker Install

The instructions say not to exceed 25 degrees, Sensenich instructions are the same. The concern is timing at full throttle. They are looking to limit maximum torque and vibration to the prop, as well as rule out racing applications. With mags, timing is fixed, so set to 25. This is fine for a plane,...

Re: Pacemaker Install

With the above complete it is time to add power. The wiring harness has a single red wire sticking out, beyond the interface panel connector. Route this wire to a switched 12 volt supply that will be used to turn the ignition on and off. If replacing mags, this would involve re-wiring one of the mag...

Re: Pacemaker Install

Getting towards the end. Re-install the flywheel. Assuming the engine has not been rotated since removal, the TDC mark should install at the top. Install the prop hub and prop, torqueing all to specification (per the prop and hub supplier). https://southernairboat.com/wp/wp-content/uploads/rtMedia/u...

Re: Pacemaker Install

All of the above can be completed without changing anything on actual operation of the engine. I actually installed all of the above one day and went out frogging that night, still running on mags. But, since my Port mag was missing on a cylinder (one of the reasons I decided to pull the trigger on ...

Re: Pacemaker Install

Next I installed the MAP sensor connection. This install is on an injected 540 so the MAP signal comes from the intake manifold. There are 1/8" plugs on the PORT side, bottom of the intake manifold. Per Daren I used the plug shown, the kit comes with the proper fitting. Daren advises that the s...

Re: Pacemaker Install

The next step is mounting the timing pickup. Since the pickup is mounted close to the alternator belt, on my original installation I was concerned about a belt failure trashing the pickup. Since then I have failed a belt and never even knew it (until noting the voltmeter stuck on 12 volts). Regardle...

The coil packs mount to the top of the engine case, using the stern 3 case split bolts. Note that the paint is removed from the mounting surfaces of the plates as the coils are grounded to the case at this point.

Re: Towing

In my opinion a half ton pickup is a good all around tow vehicle for any single axle trailer. You can tow bigger, but 3/4 to 1 ton is what you want with 2 axles. Jeeps are squirrelly enough by themselves, they make towing a chore. If you want comfort, the new crew cab trucks can be rigged out with p...

Pacemaker Install

With the water dropping, froggin's been good, but the engine's been acting up and a mag drop test confirmed I needed some ignition work. My first thought was to start troubleshooting the mags, but I quickly decided to move on to the correct plan. A few years back, I realized that VHF dog tracking ge...

Re: ECOTEC 2.0 LTG SWAP

So, I tried a few simple ways of taking up the space between the two nuts and not allowing them to move closer together. The space on the bottome bolt was perfect width to just fit a pipe clamp that I had around the bolt. I beleive that one is good. The top two were too wide. On the back bolt I cut...

Re: Lycoming Bayonet CHT Deep Dive - Cheap Sensors

While that would provide some indication of temperature, I would expect it would read low. The Thermocouple well on the Lycoming cylinders is a couple of inches deep, putting the thermocouple right next to the wall of the cylinder. I consistently read 50-75 deg. F low using an IR on the spark plugs ...

Re: boat hooks at high speed

Trim tabs push your nose down, which can resolve porpoising, but in your case it would aggravate the problem described. when it hooks the tab is in up position, but it does not go way up either. - I noticed the trim tab does not have the edges bent up on the sides or corners. It is a good possibilit...

Re: Lycoming Bayonet CHT Deep Dive - Cheap Sensors

I have had a chance to test the setup. I bought an oven thermometer to confirm the kitchen oven settings and compared vs. the gauge readings. Since the house AC is set right around 75 F, the gauge should read correctly. At 350 F and above, the gauge reading was within 10 degrees of the oven reading....

Not sure why the 2 leading prop manufacturers both gave a conservative 2:1 ratio, hence the real reason for my last post. Because you gave them the boundary conditions of 78" max prop diameter and 4,850 max engine RPM. Talk to them again, but with bigger prop diameter and more RPM and you will...

This engine while built strong was not built in mind of bolting a box to it. Forged rods and pistons but a cast steel crank, which may or may not hold the 500 hp they claim.

Re: O-470-11B Continental

This thread has good coverage on a 520, should provide some pointers, particularly regarding valve adjustment. 520 lifters have a pretty big adjustment range, close to 1/8". I would guess the 470 is similar.

I had a chrome cylinder handy, here are a couple of pics. The cracks in the chrome are a feature, they hold oil, otherwise the rings will wear out quick. Getting the cracks right is a bit of an art form. Note that plain steel bores use Chromed rings. Chrome bores use iron rings. There is also a nitr...
