Heavy. Low power output if it's direct drive. Do a search on this site for small block Chevy conversions, or "SBC." Lots of stuff here. It's not a simple thing to do.What do you all think the weight of a Small block chevy (350) with a Iron block, but aluminum heads and an IVO prop, also, What kind of instalation issues might we forsee using this setup?
AD,RJW, how much does your bell housing weigh? I would like to get an idea of how much a direct drive would weigh if it uses the bell you have, a lightweight flywheel, an auto bearing housing, and a custom made shaft.
I have yet to start on my build. I live near the Legends. I plan to use a 383 stroker that's in a friends garage. I don't plan to go for all out proformance but something that I understand. I am interested in seeing what you have done so far.Weight is very close to 425 pounds runnable but not including flywheel, prop drive, motor mount, or cooling. Add weight of Ivo prop. Expect around 200 to 225HP for direct drive. Add 80 pounds for a gearbox for an additional 75HP. Politely ignore those who say 6 liter V8s of any (affordable) kind will make a reliable 400 or more horsepower. And as Dan said, do a search here. There is a lot of stuff on the subject.
What are you working on? I am designing/building for SBC power. I live in KCMO.
...IF (big "if") it will survive for hours on end at maximum output with simple splash lubrication, it still does not have provisions for a constant speed prop. And, it's another 65 pounds on an already porky powerplant.You really can't beat that Rotator gearbox price...
And herein lies a problem, when there has been what seems like a reliable prop reduction, it has always been very expensive; Geschwender, EPI, Bud Warren's Geared Drives, etc. Also, they seem to be mainly just the reduction and no accessories, really. What is needed is a relatively simple and inexpensive and PROVEN kit to convert a small block Chevy to a reliable, if somewhat heavy, aircraft engine. In my mind, and many other folk's as well, the whole point of using an auto engine is to save money....IF (big "if") it will survive for hours on end at maximum output with simple splash lubrication, it still does not have provisions for a constant speed prop. And, it's another 65 pounds on an already porky powerplant.
Get a few thousand hours of aircraft use and I'll be more enthusiastic.
AD, I’ve had the same thoughts. A simple direct drive conversion package should be a winner. It really doesn’t seem difficult to put together a cheap, reliable, 500-hour-durable, 225HP package weighing less than 500 pounds. But would anybody want it?I think there is an opportunity for someone to sell a complete package to convert an SBC...
Hi Eric, I’ve seen your model. It’s very cool. Keep working on it. It would be great to see your concept fly.oh I forgot..This airplane would be all wood and some composites
