Gearbox Home at Last!

Good Morning, I drove to Port Huron MI on Friday and picked up my Auto PSRUs BW350 gearbox and I am very excited to get it out to the hangar. The only thing holding me back from getting the gearbox reinstalled on the engine in my RV-10 is the weather. We have been under siege here in Southwestern Ontario as of late. The snow just keeps coming and coming. The temperatures have been consistently below -10degC during the day and as low as -30degC at night. Not very conclusive for working in an unheated hangar. Here is a photo of the gearbox in the shipping crate. Stuart did a great job of packing it and as such it arrived from Continue reading Gearbox Home at Last!

YouTube Video of Engine Running On Test Stand

Fellow LS1 Aviation Engine Enthusiasts, I have received a link to a YouTube video of my gearbox running on the test stand. Stuart Davis sent me this video so that I could see it running for the first time since my old gearbox failed. It was wonderful to see it swinging a prop again.   You can see the video here: Auto PSRU Gearbox on LS1 Stuart told me that the testing of synthetic lubricants in the gearbox is complete and that he is going to be shipping it back to me next week. I can’t wait to get it hung on my engine again. My MT propeller has been sitting on the floor for over a year and I Continue reading YouTube Video of Engine Running On Test Stand

Great Gearbox News – 100th Post

Hi Everyone, Great News today on what is my 100th post! I received word from Stuart Davis at Auto PSRUs that my gearbox has been thoroughly tested and now has 10.5 hours on the test stand. The gearbox has functioned very well and the oiling system has done the job of lubricating the bearings and supplying oil to the prop governor admirably. Stuart is doing the final oil analysis and checking the filter media before packing it up to ship back to me. I will have it in my hot little hands in a week. You know what this means! I am going to have to get moving on getting the hangar’s heated work room finished and start working in Continue reading Great Gearbox News – 100th Post

Changes in Cooling System Philosophy

Good Morning! I have been devoting a lot of thought to the design of the cooling system in my RV-10 in preparation of installing the belly scoop and radiator. I have the basic template drawn for the belly scoop using the numbers given me by Ross Farnham in Calgary. I have ordered a new radiator from Bill Kydd in Mount Brydges Ontario. The new rad will be approximately 28 inches wide and 12 inches tall. It is a dual pass radiator which means that both the inlet and outlet necks are on the same side. Coolant enters the upper inlet neck and travels through the upper half of the radiator. When it hits the other side it descends within the Continue reading Changes in Cooling System Philosophy

Gearbox Oil Filter Types

Hi Everyone, I want to take a minute to talk about the filtering of PSRU Gearbox oil. The gearbox that I purchased for my RV-10 from Geared Drives came to me with a Fram oil filter installed on it. It turns out that the selection of an automotive engine oil filter designed for 10W-30 oil isn’t a good choice at all when trying to filter gear oil. Testing has shown that the gear oil doesn’t want to go through the paper filter medium very easily and as a result, pressure builds up ahead of the filter which forces open the bypass valve. This results in unfiltered oil being circulated through the bearings and the addition of air to the oil Continue reading Gearbox Oil Filter Types

I am going to make some changes to the C-GVMH

Hi Everyone, Thanks to all of you out there who have been stopping in to see what I have been doing and sorry AGAIN for not keeping up a regular posting schedule. Life just conspires to get in the way. The last time I posted, we had just flown my RV-10 for the first time and that was very cool indeed! The aircraft now has about 18 hours on the airframe and flies like a dream. We did the initial testing at St.Thomas Municipal Airport (CYQS) and then moved the plane to Collingwood to do my transition training. I was about 5 hours into my transition training when we experienced a gearbox failure and had to make an emergency landing Continue reading I am going to make some changes to the C-GVMH

LS1 Intake System for the RV-10

Welcome Everyone to another Kit Aircraft Mods Post! Today I am going to talk about the intake box that I designed for my Geared Drives LS1 installation. The Geared Drives (now called Auto PSRUs LLC) firewall forward package that I have seen installed in the company demonstrator and a couple of finished aircraft at Oshkosh utilized a conical intake air filter mounted to a tube leading to the intake throttle body. This is a simple solution to getting filtered air into the engine. It draws intake air from within the cowl near the firewall. In my installation I wanted to modify the existing Van’s cowl intake scoop so that I could harness ram air effect to gain some added horsepower Continue reading LS1 Intake System for the RV-10
