Re: GSO 480 set up

What diameter prop are you running and at what pitch. Really need to get an accurate tach on it. The higher the RPM of course the more boost there is no blow off valve like there would be on a turbo set up. If you can put a boost gauge on it to see how much boost you are getting that would also tell...

Re: Tuning a Lean Running O-540 & 6AA / M5-4 Carbs

Did you modify the shroud yourself to go around the ignition coils or did you get it that way? Who's built the shroud?

Banded cage wire

Getting ready to powdercoat my cage wire and band it to the tubing. Does anyone who has done it before have any info on how close that you are putting your bands. I have the tool and the bands just not sure of the best spacing.

Re: Finally almost there !

Well I'm one step closer to cranking this thing. Big Thanks to Darrin Davis and Jerry Cypret, got my Pace Maker ignition installed and they did a jam up job. Now if this weather will straighten out I'll get the cage and prop installed and see how it runs

Re: Finally almost there !

Finally filled up the tank and spun it over. 50 lbs of pressure just cranking with the plugs pulled I think it will be ok. Going to load it up this week and take it to have the ignition put on it and finish the build. Can't wait to get this thing in the water

Re: Need help figurung out what egine I have

From the limited experience that I have with Continentals it appears to be an 0-470 Not sure of the HP but would guess in the 230 to 250 range.

Break in oil

Getting ready to crank up a GSO540 that has had the cylinders re-done Didn't do anything to the bottom end except look it over and everything there(bearings and cam) looked good. I believe I should use the mineral oil for break in. Does anyone know if Phillips makes a mineral oil or are all of their...

Finally almost there !

This might sound like a silly question but after a long journey I'm going to finally put some power to my new build and spin it over to at least get some oil circulating through it before I take it to get the ignition put on it. It's a GSO540, I got the oil tank from Hamant and it appears to probabl...

I don't think so Rick . I saw his post on facebook that he was advertising for work building riggings. Hope anyone thinking about using him will do their due diligence before entering into an agreement with him.

Oil temp sender on GSO-540

I'm having a problem I'm sure others have run into but haven't been able to find a tread here that talks about this problem. I removed the old aircraft temp sender on my GSO540 and it is a 5/8-18(fine) thread that seals with a copper gasket. Went with an Autometer electric temp gauge on the new buil...

Re: 0470 PERFORMANCE HELP??

If you are going to consider a turbo just know that you will probably have to replace the pistons at least and make sure the bottom end is in good shape to withstand the added cylinder pressures.
