Dan more power is always available no matter what the engine but at what cost? They currently have a highly modified VW that puts out a shade over 1000 (that's right a thousand) horse but you sure wouldn't find me flying behind that grenade. One of the main reasons I chose to go Corvair is the fact that 180 HP is not unreasonable since GM didn't change a thing on the block or crank itself for their turbo models. Of course this was on a road vehicle and does not apply to aircraft applications. I'm following WW's turbo experimentation very closely as this along with modern fuel injection would seem in my opinion at least to be the way to go for excellent torque and fuel efficiency. Modern electronics has allowed these systems to be self adjusting to 10,000 feet doing away with complicated mixture control. Of course all these improvements are highly dependent on a reliable electrical system but as so many KR builders have proven over the years, anything is possible given enough determination, money and staying power. As I was scrapping out an old Dodge Caravan the other day the throttle body fuel injection manifold caught my eye. The letters 3.0 liter as well as the fact that it is compact and completely made from aluminum started the wheels turning. Needless to say the complete unit, sensors and wiring harness were carefully removed before the carcass left for the scrap yard. Maybe one day but for now it's getting a stock Corvair built and mounted for flight. Doug Rupert
Yes, is have seen this done. There is VW repair and machine shop, or was, in Donalds, South Carolina. The owner, Pat, made a 1/2 VW into a 2 liter engine I am sure that Jerry has more of the specifics on this, but I have seen it done. However, I don't think that I would fly behind it. Daniel R.
