Evolution 26GX
Greetings All,
I have acquired one of these , it is New and never run, I was wondering about break-in on it.
I know that they have there own Evolution synthetic oil available, but was wondering if something like Saber or Dominator (both synthetic) would work as well? also what mix would be good to start out with for break in on this eng and then what mix for after break-in.
With the gas I run 97 octane 50:1 in my 3W55 TOC that is what they recommend I am wondering if the higher octane would be fine in this or should I be using good ol reg gas at 87 oct.
I did call Horrizon and the product support I received was basicly NONE. I asked the person I spoke with if he had any experience with this eng and he said SHURE I DO. Well I am going to say that He does not! he said to break it in on 20:1 first I said isnt that a little light on the oil for this, reply was well yes it is, I told him of the Sabor and the Dominator and that they are 100:1 syn oils and asked about that and he said that is fine break it in at 100:1, I am thinking why did he say 20:1 I asked about the octane of the gas and he said use what ever you want.
SO I am here asking if Any One has any experience with this eng and what the recommendations are of Current or Past users of this eng.
Thanks in advance for any replies.

RE: Evolution 26GX
I have one of these engines and it runs like a champ. I've currently got it in a QQ 23% yak and it does a great job. I ran mine in at 32:1 lawnboy for a couple of gallons and then switched over to Mobil 1 2T synthetic at 50:1 and have no problems. I also use premium 91 octane in my engine and get 8700 rpm on the ground with an evolution 18x6 and 8450 with a Xoar 18x6. The Xoar is less static rpm put pulls like a horse. 
I know guys have posted on here that they can't get high rpm numbers w/o a tuned pipe but I'm running the evolution inverted pitts and getting really good numbers.
For the most part I don't think it matters if you run it in on petroleum based or synthetic base, synthetic will just take a little longer to seat the rings. There are plenty of guys here that run the 50:1 amsoil and don't have any problems. I also know some guys running 32:1 synthetic without issue, I just personally think that's a little too much oil for it.

Thanks for the Reply, that is exactly what I did with my 3W55, 2.5 gal of premium with lawnboy and now 50:1 with Dominator synth. That eng pulls my 21lb Python Pitts around like a .40 size ship that is over powerd.
I will be putting this eng in a Sig Rascal 110 and will be running the Xoar 18X6 on it.
I want to give this eng a work out as it may be going in a H9 P47 150 next but want to run it in the Rascal first for a while.

RE: Evolution 26GX
I wouldn't see any problem with that, that rascal is such a mild plane that a little bit of extra power can make the plane cable of doing things never envisioned. I guy that used to fly with us had one and he would do knife edge passes and could actually hover it for short periods of time.
I wouldn't trade my little evo26 for any other motor in this size, it's been reliable, performs well, and suprisingly economical. I've got a 12 oz tank in my plane, can fly for 10-12 minutes and still have 1/3 of a tank left doing mild aerobatics with it. I think you'll really enjoy this engine.

That is what I hear about the Rascal, you can have some real fun with it, will be a great test bed for this eng. Thanks for the tip on the 12 oz tank I never fly for over 12min or so anyway and it is always nice to have a little extra for a go around or so, also you dont need to carry any more fuel than what you will be burning with in reason.
I got my 26 at my LHS for 440.00 I dont know if that is a good price or not, I like to support my LHS as much as possible they do treat me as good as they can, and still make some $$$$ to keep the doors open.
I know for a fact the there cost on the Rascal was 330.00 (sneek a peek at the invoice)
and they charged me 350.00 for it, so they get my business as much as possible.

RE: Evolution 26GX
You might watch your fuel close till you get leaned out. I actually had a dead stick cause I was on my second tank and lost track of time and ran empty after 10 minutes. I'm getting a lot longer than that now that I'm tuned correctly, but I also spend a lot of time at low throttle in high alpha.

Use only premium gas, 91PON or better, leadfree. 87PON will ruin your engine.
For running in, use the same fully synthetic racing oil as for later running, but at 3-4% mix (1:30). Don't believe all the mumbo jumbo about mineral oil for running in. Only lesser engines require the extra wear that the mineral oil provides to seat the less than perfect ring lands.
when run in, use a 2.5% oil mix (1:40)
There are several oils marketed that fill the bill. MVVS recommends Mobil 1 2T racing (I have a stock), but other fully synthetic racing oils that exceed a viscosity of 10 ctokes at 100C also will do.
Considering the basic requirements of the engine, Amsoil Dominator is not the way to go. It is way too thin with only 7.6 cSt@100C

RE: Evolution 26GX
you cannot find Mobil 2T racing in any ESSO store any more. Mobil has stopped this niche market production.
However, MVVS has sufficient stock, and they supply to me. (and other mvvs dealers as well I suppose)

RE: Evolution 26GX
Jones, several of these oils, including the Mobil mentioned, can often be found in local motorcycle shops.
Pe, I'd not agree that DA engines (or many other fine brands) are "lesser" engines than MVVS just because they recommend starting initial break-in with mineral oil.

RE: Evolution 26GX
I know they don't make it anymore, but I can still get the mobil 1 2T from my local auto parts store. I've got 3 quarts right now, but called them to check and they have 2 24qt cases in their hub warehouse. I might buy a few more just to have em stashed back.

RE: Evolution 26GX
The plastic mount will work ok, but I'm using the radial mount that's available for the engine. The plastic mount flexed a little too much for me, had ugly vibration, hard mounted using the radial mount and the vibration level dropped quite a bit. (and for those wondering, the prop and spinner were balanced [)

RE: Evolution 26GX
DOn't stress if you can't get the mobil 2T....
Any Fine Motocross racing syn. oil should work out well..... Bell Ray or Honda for ex......
pe reivers Knows these engines quite well.....
I would take his information on breaking these engines in and what kinds of oil to use as the Handbook Bible.
The whole petro/ vs\ syn for break in is really a manufacture choice...
Almost as heated as the 3W vrs. DA!.....
Pepsi VS Coke..... ect...
I personally think it's fantastic that it can use the syn. right away, as I will obviously be much slicker (keeps the engine looking knew inside)
and very minimal fouling... Unlike the petro based oils, which can leave varnish on the piston top even after 1-tank of gas..... during break in....
