Gipson's RV-10 with Geared Drives LS1 Engine Runup

Bill Gipson of Conroe, TX runs his RV-10 with the Geared Drives PSRU and LS1 Firewall Forward Package built by Bud Warren. Notice that the engine runs great at any RPM. We are expecting fuel burn rates from this combination in the range of 7-15 GPH. With torque multplication throught the Geared Drives PSRU the performance will be astounding! Be sure and notice that there is no gear noise at all heard with this redrive, just the smooth throaty sound of a Corvette engine.

being that a RV-10 running a 260 has a stated rate of climb at 1950, I'm guessing your probably into around the 2500FPM range? Have you completed the build yet? what is the cost for an option like this? obviously taking into consideration a certified 540 can be had for around 18-24 depending on who ya know?

@gilly87S -This aircraft is completed and flying. Just made a trip from Houston to Oshkosh to the airshow and back in fine style. Climb rates are at 2500 and higher, depending on how hard you want to push. Engine packages complete are in the $32,500 range, add your prop and governor. Brand new modern technology and 40% better fuel burn than a Lycosauras.

How does the weight of an LS1 compare to an IO-360? Too bad you can only put an auto engine on a homebuilt.

[geareddrives]

@dragracingz28 A little too much weight to replace a 360. This would be great for a replacement engine for a 6 cylinder certified

What kind of heads are you running on this application? I was told that the engine needed 2 plugs per cylinder to use in a plane, was that incorrect?

[geareddrives]

@probuiltlakecity Two spark plugs are neede in aircraft engines since they lead foul so badly. Bottom plugs face upward and collect the lead. Auto engine plugs face downward and do not collect lead, and RARELY do they foul. Even so, if one did, there are seven other cylinders and plugs and the computer will smooth out the engine and you can still fly it to the ground for service.

Just think come overhaul time all you have to do is run down to your local chevy dealer and order your parts!!!

Now if he really wants to go crazy get a procharger, cams, borla bullets exhaust, and a custom computer remap maybe a diablo tune you know. =]

So does it fly?

[superskullmaster]

@SpidMovie How reliable was the liquid cooled P-51 Merlin engine? Or Rotax liquid cooled engines? Look how old that engine (Merlin) is/was and how reliable it is/was. Why should this be different just because Lycombing and Contenental will say anything to keep selling thier overpriced engines?

[Dominoes282]

I LOVE how it sounds like a turboprop. Not the engine but the prop.

[SpidMovie]

Don't get me wrong, I do love this engine (I drive a vette with an old LT1 engine). However, since it's not certified, what's your concerns about reliability? Any problem with?

[MartySchrader]

1 7/8" headers with open dumps? Man, that thing must be loud! Pulls pretty hard, too, I bet.

Hey Budd!!! I´ve been following your accoplishments and developments here from Brazil and I apreciate your readyness in answering questions to the guys on the net. All your answers and ideas simply make all the sense to me. By the way, couldn´t you post a video of this particular airplane flying? What is the status of the Bearhawk set up?
