Polishing your nitro engine can be the best performance boost you can get, Nitro is my passion, racing is my addiction, wrenching is my life.

I guarantee that polishing the outside of the sleeve will do absolutely zilch to performance but it looked good.
It's actually a bad idea I polish stainless steel and brass using polishing compound is like using fine sandpaper it wears down the material especially brass. Brass is a soft metal easy to polish and remove scratches problem is you have to wear the material down to get the scratch out.
@@TherealMandingo it doesn't take off enough material to make one of these engines angry though, they're a lot less sensitive than we think they are. I agree with Baldrick though, not a lot of performance gain anyway
@@wyattfair1957 it does matter each time does that he's pulling material away then the thermal growth from the engine heating up you have now lost compression now the sleeve won't shrink back to its original size. Dam straight those measurements are critical take acouple mm off the top of one of the ports
@@TherealMandingo Oh I agree completely millimeters would matter, but that would mean a grinder or Dremel. When I checked my polish job it removed microns, literally 1/10 of a thou using a Starrett micrometer from the brass sleeve and nothing discernable from the crank pin. And I'd be surprised if most of that wasn't from dirty nitro oil residue that's been cooked on and sitting for the last 10 years. My OS .21 is a buttery smooth monster now, I'll give most of that credit to the Boca Ceramics but a clean engine is a happy engine :)
Edit: the inside of the sleeve went untouched, I still had crosshatching and good pinch on the piston so I left it alone and agree that polishing the inside is a bad idea 👍
I think you will diminish compeession on every time you pull out piston, you cannot align it that way it was and polish outside will do not realy something beside destroying the seal
That did absolutely nothing for performance. If you want to polish something, do the inside of the port on the cylinder body where fuel runs up on the outside of the sleeve.
Great video! This is a great breakdown of maintenance on the engine. How often do you break it down to this level of detail? Between every race, or do you run it a few times?
Interesting cool video bro i run a bunch of different nitros always looking to pick up something new
Please share the link from where u for those tools to hold the sleeve and button. Thanks
I did not know that polishing would give more power and reliable always thought cross hatching like in a gas motor was best to use so oil didnt pass passed the piston and lower your compression pressure but I guess 2 strokes like oil going into the compression stroke
I would say polish the piston the out side nice and smooth. Before break the piston and sleve In together while the pinch is tight.. just a thought
NO
That is stup*d dude,the whole point of breaking in the engine is to lap the piston to the sleeve, if you want to polish the top of the piston to remove carbon OK,and dome in the button to reflect heat better,but the guy in the video is anal and you can tell he wants his engines to look brand new,even shows off the new boxes of engines like a douche.
I highly doubt that makes any significant difference in power or how it runs to be honest.
best performance boost i ever!! did in 10 years! was send 12 top shelf engines to rcrenew! oh what a differance! better than any polish! job ever!! lol!
Great video, your RC knowledge is vast my friend. Hey kind of silly question, but I struggle to find good microfiber towels. Or they are so expensive you don’t want to use them lol. Do you know what brand and where you got the ones you used in this video?
I usually get the color pack from Wal-Mart, i think theres orange, blue and yellow the packs i buy ill check the brand and let you know 👍
The only thing you should polish is the exhaust port on an engine the intake an intake port shouldn't be perfectly smoth the texture helps Adammise an evenly burn the fuel
😂😂😂 aside from the obvious bs here; I would NEVER recommend taking engine advice from someone whom can’t even SPELL “atomize”…
Will, do you polish before initial break-in or for general maintenance after break-in? Thx
Sometimes before
The only polishing that makes sense is the top of the piston and the head button because that’s where the most intense heat is and the polished surface reflects the heat better. Everything else is just for looks
Hmm. Almost everything done is “cosmetic feel good”. I didn’t see anything that would help performance. If someone has some theories as to why this works I’d love to hear them.
Why would you polish the outside of the sleeve? I'm not mocking i genuinely would like to know?
A smoother surface will make the fuel flow into the chamber at higher velocity without sticking to the side of the sleeve, kind of like ceramic coating on a car's paint 👍
It doesn't do shit. I guarantee you'd NEVER notice a difference.
Exactly. No point just a waste of fucking time. Who is this guy lmfao
it is none sense to polish the sleeve from outside.
Completely...
Very cool I will be trying this out! where do you order those drill bits?
They should be in the link below
Does polishing the ports and Crankshaft brings a lot power ? How much does this do in terms of power ?
Very minimal gains, it's much more about smoothness of the engine which will help it RPM faster and cleanliness which increases longevity. Also if you don't clean everything properly before reassembly after you polish you'll do more harm than good!
Using polishing compound is a bad idea those sleeves are machined to tight tolerances using polishing compound wears the sleeve inturn the heat will expand it making it larger so now you lose compression
It should come polished out of the box lol
👍
👎
What do you charge for this maintenance service?

No benifits what so ever if anything you have taken mild tooling marks out of the metal giving the part less surface to air contact witch will just make it heat soak faster
Oh' thats! Modifikation Not too' much Help, meby more Work time & Name: Material Verschleiß open- Close.
Mute it ASAP
I think next time you should just polish your "rod" instead, at least you would actually achieve something. Maybe...
No point in polishing the outside of the sleeve. Waste of time and probably lost performance
Well thats a great way to waste your time.
First 5 seconds of the video , and you know trhis is BS
Absolutely a complete waste of time. No gains what so ever.. the ONLY potential here would be a negative outcome. Wtf..
