Looking good!
As for oil lines check speedway motors or summit racing. They both have AN FITTINGS AND LINES SN 3-4 are Prakrit line sizes . You probably don’t need the super high pressure stuff. There are push on braided lines tag would look ver nice on you enging.
That would be absolutely cool to have two of these with black 3 blade props running on a test stand. You will be getting close to drag race operations you might need a crew maybe even a goose neck trailer and a one ton dual Ky truck trailers are called “ toy haulers” they have a garage in the rear. Usually 3 or more slide outs. You could have a complete shop in the garage area.
rlo,
I hit up SummitRacing last month for some AN3 stuff.
great minds think alike!
Tubes would look good on this. Thank you for the heads up on the frothing issue. -RonO
as far as the oiling system goes I’d have to dig out my drawing set I don’t remember the thread or opening sizes . The scavenge pump needs to be quite a bit larger as the oil is aerated rather than liquid. You also need an unrestricted air intske. I woul surely look at AN fittings as the braided hose looks nice and you can get red blue clear or black aluminum fittings unless abused these don’t leak you could even get ones that have o ring seals these are what we use on the racers. The hose is quite flexible even in the smaller sizes you cn get push lock fittings so hose assembly is quick and easy I’d think a #6 would be ok for return line and 3 or 4 for feed lines bush rod tubes would save a big mess LOL
If you want to see how modern cars that used dry dump you may want to look up the system used on corvette and some Camarillo cars . It’s kinda intimidating . . Generally a round tank wig internal-baffles and drain holes will strip the oil and air. Our race tanks are pretty simple as there isn’t a need for constant circulating oil the tank is just a large reservoir then a place to pump the aerated oil so it can be drained in a few seconds. This is 70 weight oil full of nitro so a pretty big mess. Certainly not very green however used oil is placed in drums and allowed to settle then sent to recycling center. The nitro will settle out but usually not reused . As it still has oil in it. Somewhere I recall that castor oil is stil used in model engines it will definitely be a good mess it doesn’t wash off easily and leaves a brown sticky mess around exhaust. Many years ago mode glow fuel had lots of castor oil it smelled ice but was really hard to clean up I have a single quart of it I YHINK use in the freezer for some forgotten test I was going to do .
I think all three have been used. Somewhere I think the original cushman car by is now available. Float style plain Venturi carbs works bu you need constant fuel pressure . Small engine car by have pulsating vacuum pumping built in . By the engine they are a float car by but you will still need a small fuel pump.
Interesting. The drawing with that tool was the first page in the set I got . I looked it ove pretty closely even with double vision you would think I could see the round shaft . I had the cad program up and running I looked s number of times
