    Custom Turbocharging a Continental GTSIO-520

    Ross is the MAN on this topic for sure...... 30 years ago I was involved in some radical tractor pulling rigs and we would stage 3 turbo's..... Get 110 PSI boost pressure.... Ran CO2 cooled intercoolers.. No one had tried the Methanol /Alcohol in Diesel motors like they do now...... Kool stuff...

    Eco-Fly Smart deisel

    I doubt you could re- machine the clearances to allow for dry kerosene like JetA... Much easier to just add a small amount of 2 stroke oil at each refueling.. Probably only need a quart for each 100 gallons to restore lubricity... IMHO.

    Van and Flowscan in the Crosshairs of a Lawsuit

    When the builder / pilot fills up the fuel line full of RTV silicone and plugs up the fuel flow..... The motor WILL quit running..... Pics are from the NTSB autopsy of the wreckage fuel system... http://dms.ntsb.gov/public/57000-57499/57129/570028.pdf Accident ID WPR14FA218 Mode Aviation...

    Return fuel flow rate?

    Great advice.. Altho my experience with a throttled back V-8 at those HP output numbers will give me BSFC numbers of .38 /.39.. BTDT..

    Return fuel flow rate?

    Great advice..... I am in that HP range and my 3/8" lines don't hurt my output at all..... The biggest ( smallest) restriction in the entire system is the orifice size in the Flow scan Flowrator for the JPI 450...

    Older IVO prop removal

    Ok.. That makes sense.. The shims actually push on the rods when the entire sandwich is tightened up... Correct?

    Older IVO prop removal

    I am a bit confused..... The older IVO's didn't have torsion rods embedded in the blades to twist them ? Where did these shims get stacked at ?

    Electric pop rivet gun versus Air driven pop rivet gun, any suggestions ?

    1/4" Stainless... HOLY CRAP..... As a builder who pulled 14,210 rivets while building my Zenith 801. I can say the air riveter is the only way to go...

    Older IVO prop removal

    Ross is seeing the same thing I am..... This installation will just give the pitch of the prop as built. I do not see the Ivo adjuster in any pic...

    Delta Hawk Diesel

    Ross is right on with his thoughts.. From the beginning Delta Hawk has been using a similar business model alot of Dot Com tried. They touted pie in the sky ideas based on paper /vaporware... Their business model is /was to cash in and sell out to the Chinese like many other aviation companies...

    Those are called In /Out boxes and they come in various configurations.... Mostly used on dirt sprint cars and midgets.. Their function is to couple and uncouple the power output.. A DD will still need to address thrust forces, rotational forces and gyroscopic forces from the prop..
