I operate off an airfield with a ground elevation of 5327 feet ASL.
Obviously my engine (VW 1835cc with Zenith Carb) feels the altitude somewhat. I am thinking.... Would Turbo charging help? What about an electric blower to increase manifold pressure maybe? Or how about a NOS system? |

How about building a 2180.
Personally, I'd not fly a turbocharged VW. Ever. Richard htp://www.flash.net/~lamb01 Andre wrote: I operate off an airfield with a ground elevation of 5327 feet ASL.

"people with less brain power than you are doing more difficult things everyday"© Yep. We have a lot of VW powered airplanes around here. Heck, I've had two myself, and a new one about to hatch. A home brew VW engine making 50 HP or so is one thing. A home brew turbo is another breed of cat completely. I'll happily let those with less brain power have at it. Either they'll design a good waste gate control system, or they will blow the engine (real bad pun). There is what you know you know, What you know you don't know, What don't know you know, and what you don't know you don't know. That last one seems to cause a lot of problems. |

![]() Okay, I know I'll get clobbered by BOb on this idea but here's at it. There was a guy in California who spent a lot of time tinkering with propeller mechanics. Now this was done to figure out how to wring out more energy from the wind for those electrical wind generators who's designers seem to always copy the airplane propeller to catch the energy from the wind. Now I read this in Popular Science and was fascinated with his findings. So much so that I wondered why the reverse couldn't happen. Namely, take his redesigned wind machine propeller and use it on an aircraft. The reason? He managed to prove his design could get 45% efficiency from the wind rather than the 12% from the airplane propeller. Anyway, his working model impressed Popular Science Mag enough to publish his results for wind generators. So . . this propeller could make a 50 HP VW motor very . . . ? *p.s. those % are from memory. Richard Lamb wrote: Yep. We have a lot of VW powered airplanes around here.

You are so far into Looney Tunes and Popular Science, I'll just sit this one out, thank you. g Catch ya later, Woody. Barnyard BOb |

So . . this propeller could make a 50 HP VW motor very . . . ? *p.s. those % are from memory. There you go again. 1. the airfoil on a wind generating prop has the camber on the opposite side from an airplane prop. He was lucky to get 45% 2. The usual range of efficiency on an airplane prop is not 12%. It is closer to saying 12% in-efficient! There are LOTS of very smart people doing the propeller thing. You, or any other backyard carver, will not improve on it. Suggestion. Stick around and just read for a year or so, without posting. You will be amazed at how much you learn you didn't know. -- Jim in NC |

writes: I'd suggest you get one or two of the 4 foot shop fans that sit on the floor. When I worked in my shop, they did a pretty good job of keeping me comfortable. Big John Point of the sword I put an airconditioner into the wall of the garage a couple of years ago and it has helped a lot. The problem with it is the garage is not insulated and it must be run overnight to bring the temp down and hold it most of the day. In the current situation that would not have helped since I was working in the greenhouse doing some staining and finishing on some doors. It is empty this time of year and is the only place I had enough room to work. I have a couple of big fans but could not use them without causing problems with the finish. Just have to wear long sleves, grin, and bear it. Bob Reed www.kisbuild.r-a-reed-assoc.com (KIS Builders Site) KIS Cruiser in progress...Slow but steady progress....
