Re: Thrust bearings? Aircraft vs. Automotive

First off I started this thread off in Airboat Talk since it includes both types of power. That being said I wanna know why everyone thinks automotive thrust bearings can't handle the pressure of a prop like aircraft thrust bearings? Other than the fact that aircraft have a floating thrust bearings...

Re: IO 520 Build on 12 foot Hamant

Sounds like it has a hook in the bottom. Mine did the same thing until I put a jack in it. The jack helped a lot, but my bottom is still not straight. I still get hop, a little trim tab takes care of it, but it doesn't run on the nose anymore. I would definitely put a straight edge on the bottom and...

Lol! I'm contemplating running a velocity stack, saw some good dyno results with them. Or possibly a restrictor plate, just curious if it would help any. I really don't want to throw $800 around just yet.

Re: Manifold air speed

That's awesome! You're using a performer air-gap right? I ran my tach wire through the center of the intake manifold, under the runners, keeping it away from the spark plug wires. I think you should send me your 2bbl for testing, see if the results are repeatable on a chevy :D

Re: PROP or ENGINE SHAKE???? above 4,000rpm

The spark plugs will tell you. Mine were wet on one cylinder which was the one where the coolant was getting by. It slowly got worse until it was smoking. At first, it would not smoke only sputter every now and then. I first stopped to see if the prop was ok because I thought it was wobbling or sha...

Re: LS DD maiden voyage

Sorry to dig up an old thread, but curiosity got me and I got bored after two pages. Was waterthunder able to develop a thrust bearing to run a DD LS? I had been wondering the same thing. I thought I saw a post back on FB a while ago where WT said they had a meeting with a big name manufacturing co...

Re: Air fuel ratio for direct drive

My old notes say go back to 36 and try 38. But Hdsadey is right, give it time to settle first before changing anything. Just don't give it too much time, you don't want her to settle on old lady going to church mode. My experience with automotive EFI systems is about 30 miles of driving is pretty s...

Re: Air fuel ratio for direct drive

Oh, and I dropped the timing to 32, it was at 36. Might try to bring it back up and see if it picks up rpm.

Re: Air fuel ratio for direct drive

Drilled the hole, it was still creeping up to 230 at idle, decided to give it some rpm and see if I could force the bubbles out. Worked like a charm, idling at 190 degrees and cruising at 186-188. It ran awesome at idle, cruise, and WOT. Picked up 100rpm on the trailer. I know it takes time to learn...

Re: Air fuel ratio for direct drive

On my Windsor I drilled a small hole on the side of the stat. It sure helped with the air purge. There is a funnel from Lisle tools that uses an adapter to the radiator cap that will let the system run and bleed off air. https://www.summitracing.com/parts/lil-24680/overview/ I also run a product ca...

Re: Air fuel ratio for direct drive

Hmmmm. I can’t speak for the EFI deal. I want the setup you have but don’t feel like messing with it. My carb setup runs a 165* thermostat with no holes or anything drilled. I added a bottle of a Lucas coolant product with my dex cool coolant. It runs at 170 to 180. Will rise to 200 if you shit dow...

Re: Air fuel ratio for direct drive

What temp is it getting to. Took a little bit to get the air out of my system. Let it sit for a few with the burp tank cap off. It would burp and need some more fluid. Ran it on the trailer for a bit and topped it off. Topped it off a week later before ride and it was good to go It crept up to 206,...

Re: Air fuel ratio for direct drive

I would think any system that can get enhanced data would tend to be more likely to forecast and respond more accurately to changing conditions. Hence the factory systems having upstream and downstream sensors. Do the FI Tech sensors have a self heat cycle at start up ? That seems to be a fail poin...

Re: Air fuel ratio for direct drive

You will see when you run the dual plane KeyPine your gonna puddle fuel. Not a issue with the carburetor nothing to effect it, those fuel droplets just burn undetected but the EFI it's O2sensors and tune map will be effected. Maybe some of the systems have more forgiving software that is slower to ...

Re: Air fuel ratio for direct drive

A lot of user data in sites like this one. Guys who experienced lean conditions on certain cylinders using a dual plane, map issues and fuel degradation to seals etc. Something to think about maybe. http://cpgnation.com/forum/threads/ez-efi-2-0-injection-with-dual-plane-intake-vs-single-plane.25871...
