***UPDATE: Edge informed me the shaft was tighter than it should be through the OEM housing. (it should go in by hand). Quick touch with a 10.00mm ream fixed it (it had actually fixed itself basically). Just wanted to point that out. Also, I had over 20hrs when I tore the pump off and took it apart to check this - and everything inside looks perfect. No wear, rubbing etc.! Good peace of mind checkup, and all is well!

start up would be faster with the regulated oil getting to your hydraulic lifters faster...opening the valves to full throw sooner even with low rpm, With good bearings & engine Warmed up! If your oil pressure moves up and down from idle to full, the high volume pump is a great idea as you stated! Great upgrade! An engine always makes metal throughout its life.... the amount of metal is highest at the beginning and end of its TBO!

Another great video Todd. I love the mix of flying and tinkering you've got going in your videos. True spirit of EAA. Question: with my stock 912IS do you think I need to worry about the oil pump? It looks like it's really an issue for turbo models with oil squirters like yours. Concur?
@GravityKnightFlying4 жыл бұрын
Thanks brother! I definitely agree with your assessment. You can always shim the relief a little if you decide you want more pressure, but most likely it will be good as is. (also, the relief shims are rotax parts from CPS etc., not some hokey aftermarket thing). In other news, I'm hearing some rumors about some various upgrades from Edge that work with the 912iS.... :) ... so just something to keep in the back of your mind if you need a little more power down the road!

New subscriber here! Have really enjoyed your videos for quite some time now and actually thought I WAS a subscriber but decided to check just now and found out I wasn’t! But that has been corrected. I’m always looking for ways to upgrade the Rotax 912ULS on my KitFox 7 and thanks to your videos, when I do, it will be with products from Edge Performance. Also, quick question if you happen to see this: What size Bear Trap oil filter are you using and how is your experience so far? I’ve heard a lot about them and have been considering making the switch. Thanks in advance and thanks for the great tutorial videos!
@GravityKnightFlying4 жыл бұрын
Thanks Jeffrey, welcome! Good question about the bear trap, I just started running that about 30-40 hours ago. So far, I've never seen any metal inside the filter that it has trapped. Possibly (hopefully) that is because there is no metal there to trap! But I figured it couldn't hurt to have another spot to grab metal and then get rid of it with the filter (I have cut every filter since adding it).
@JeffreyRubicon4 жыл бұрын
@@GravityKnightFlying - Thanks for the info and the quick response! And I agree, it definitely can’t hurt to have multiple places to remove metal. I think I will give one a try. Between that, oil changes every 25 hours (in my case anyway) and an oil analysis a few times per year, I feel like I should have my bases pretty well covered! (What size are you using? The one for “Sport Bikes”?) Thanks again.

@@JeffreyRubicon oh it's the BT500. Smaller-ish one I think. Good call on the oil analysis and 25 hr changes. I do 25hrs as well regardless of fuel used. 50 just feels like too much although many people do it just fine. 30-35 on non avgas wouldn't bother me, but I just do 25 too. Waiting on an oil analysis to come back right now as well.

more volume does'nt mean higher pressure necessarily higher pressure can effect oil seals and blow them out if it is to high
@GravityKnightFlying4 жыл бұрын
More volume will allow for more pressure when you are short on volume due to feeding oil squirters. The main problem is that at high altitudes, rotax engines oil pressure falls off to a level that is questionably high enough. Doesn't matter how high you set the bypass, the pressure won't go up because there is a lack of volume. So in this case, more volume does allow for higher pressure. Also allows for higher pressure at lower rpms. What seals are you referring to in the rotax engine?
@williamstrome52714 жыл бұрын
@@GravityKnightFlying yes I agree if you have to low volume it will affect your pressure. internal engine oil pressure is dictated by internal bearing clearances and by pump velocity if pressures are to high any engine seals can fail I have done this on high performance engines before
@GravityKnightFlying4 жыл бұрын
@@williamstrome5271 When you add oil squirters, you need to also add volume to keep up.. that's mainly what this pump is here for. (And to also combat the reduction in oil pressure at high altitudes). The reason I asked you to point out the seals you are talking about is that there really aren't any 'seals' on the rotax. There are some o-rings, but they are good for much higher pressures than we are talking about here (say going from 60psi to 75psi). The oil filter is the highest potential problem area from what I have seen. Rotax also has a rating of 100psi maximum oil pressure during cold start, and even with this pump, we are well below that... so I'm curious where your claims of blowing out seals come from?

@GravityKnightFlying4 жыл бұрын
Makes sense William. I agree in general, this is a concern with an engine... interestingly enough, the rotax seems more "tolerant" to higher pressure. But ultimately, I do feel it's important to stay under the limits set by rotax. They give pretty wide ranges, and unfortunately are very vague on why the 100psi limit and what would happen if exceeded. I saw 88psi for a short period of time when starting cold with this setup (2 shims under the relief valve). I will be keeping an eye on that when it gets colder... even though I pre-heat in the winter... I need to know if I had to start it in real cold temps I'm not going to exceed the limits. -T
