After blowing up a stock motor on a four mile final with no turbo on November, 28 2009 at KDVT, it was time to rebuild. It was too big of a temptation to add a turbo and intercooler to this RV6. Running 33" at 11,500 it sure works fine.
The company that built my motor back in 1998 was sold, changed their name, and moved so getting an explanation why the number 2 cylinder's rod nuts were in the oil pan without anything in them and why my crank was in two pieces (snapped in half) after 260 hours on a newly-built motor was impossible.
I built up a new motor O-360 Lycoming with Bendix fuel injection, 9.5:1 compression, with total seal gapless piston rings. I also added a Lightspeed dual ignition, a Rayjay turbo, and a very big intercooler. Like i said, it works really well. Temps are good; and the first part of testing is over. I cruise at 11,500 ft at 2,400 rpm, 28" manifold pressure burning 11.2 gph doing 180 ktas. Alternately: 13,500 ft 2,400 rpm, 26" manifold pressure burning 10.6 gph doing 180 ktas.
Being located in Phoenix, temps are a big issue in the summer...even on a stock motor. But I seem to have found a good combination and have temps in check running 33" manifold pressure at 11,500 ft, I get 100 F temperature drop over the inter-cooler. compressor Out temps are 230-240 F and after the inter-cooler, I see 120-130 F. Playing with the oil temps they are finally down to 195-200 F.
The gain over how it was (before the turbo) is a lot of climb speed 1000 fpm @ 130 kias all the way to 11,500 ft. I gained 35 kias cruise speed.
It was a long process, but compared to building a kit plane, it wasn't a big deal.
I made a billet oil pan, new intake, new exhaust, my own scavenge pump for the turbo, my own inter-cooler, and my own upper deck pressure injectors. I still have an inverted Christen oil system.
It sure is nice to have a forum like this to get some info. If anyone would like to try what it's like to fly a turbo RV-6, feel free to let me know...I'm always up for flying.
The next step is to get some oxygen and go high to do some testing. Hope you all have had a Merry Christmas and a Happy New Year.
