O.S. SPEED B21 ONGARO WORLD CHAMPION EDITION / A LOOK AT THE INTERNALS

[@alikhawaja6362]

Great Video brother. The head Button is a little different also compared to the B2104. I have 3 of the ongaros X1 V1 and X2 V2 limited editions. One of my best friends one said once you find your favourite engine buy a few of them as you never know what the manufacturer might do next. They might go in a direction you don’t like. So I Stocked up lol !!!!!!

[@kings-racing]

Thank you. Very good looking engines. They already announced the V3. Very beautiful, specially the pipe with the signature. I hear ya. Stock up if you like them. I regret not buying another K301ec. Love the feel and she been very good to me. It's well over 15 gallons and still running strong.

I have had Reds engines, 1 GX Racing, And 1 Hobao Hyper, 8 port race engine. I recently bought a Rbx v3 OS MaX and it looked very good, even being a lower end OS engine. Cool video! 👍

[@kings-racing]

Thank you. I've got the os max b21 and xrb. They run very good. Best budget engines out there. Thanks for watching 👊

[@TastyBRC]

Congrats on the new engine, that one is going to be a collector. Best looking OS. Very curious on the dyno. As Ongaro won again, I think we will see a new version very soon. The intro was really cool, Kings the nitro Spielberg

[@kings-racing]

Thanks buddy. Agree, she is very beautiful. Looking forward to run her. We will see if a new one comes out. I've been binch playing the intro rocking through the house screaming OS & B21 for days😆 totally crazy.... i really can't be helped.

awsome vid brother that ongaro is a nice looking engine keep the kick azz engine vids coming bro

[@kings-racing]

Thanks brother. It's very beautiful. Since i finished the intro I've been rocking through the house screaming OS & B21 for days. But for the rest i'm fine😆

[@kawicepticon8866]

I have the same one still sitting in the box...she has to jam hard w those numbers . The B2104 ripppsssss ,I have 2 modded B2104, a Muran one and the Mars Evo and they are both rip snorting nasty..esp the Mars on a V gt mani /9886..kinda shocking from such a simple looking port layout lol...all on a 9mm venturi. I cant wait for your thoughts on this one. As far as a great track pipe for the b2104 and probably the ONG is the Ielasi 2186 mated with the Reds XS or S manifold....the stock manifold sux on that pipe on a b2104 but shorten the manifold and it becomes ultra crisp and has all the revs needed on these engines while producing a wonderful sound... Again 9mm venturi . When running 7mm or what any traditional "race" size venturi ,they will always choke up the top end of an engine so I test only w 9mm to determine the potential of a engine /pipe combo, Anyways lol ,thanks for posting the ONG WC , my house hold watches all your vids when you post them..we are a house of NITRO ! Later broksi

[@kings-racing]

If you have the B2104 maybe keep this beauty in the box. Definitely gonna hurt scratching her up. I will try some different things after i've ran her. Appreciate the comment and thanks to the whole house hold for watching. That's awesome 💯 here it's only me rocking and screaming OS & B21 through the house. My wife thinks i'm totally crazy..... hoping for you to tell me you all do that too and i'm perfectly normal 😆

[@kawicepticon8866]

@@kings-racing i think she is staying in the box, shes wayyyy too pretty to get dirty.... maybe I will snag a crank and test it in one of my 2104s. Yep your are 100% normal in my book..its the electric guys I worry about. Pshhh getting excited over voltage and what not smh. Yeah bro I totally get it , she use to be that way but I turned her into a gear hear .lol She use to seeing me do everything from making fuel, build meth injected jeskis, nitrous fed superbikes, etc... I think she has learned nitro to try and keep me off the big boys toys..now that we have a 3.5year old but hes as bad as me! lol So we all watch the good nitro content on KZbin and then we typically head to the nitro room and mess with something or put a mod or setup on the white board to test on the golf course the next day. LOVE OUR HOBBY! See ya next video brother

[@mcnitro874]

awesome bro do you make these background tracks yourself 😮

[@kings-racing]

Thanks brother. Yes, i've been making the intro music myself. Appreciate you watching 👊

[@mcnitro874]

@kings-racing that is unreal man

[@henriksrensen3220]

Hi. Great video. I can only get 16% nitro fuel (by weight) here in Denmark. Do you think that engine heat will be a problem? And what about tuning? Is it difficult to tune engines on low content nitro? Thanks in advance.

[@kings-racing]

Thank you. 16% by weight is actually 12%. In the winter time heat will not be a problem. On a hot summer day the tune will be a bit rich to keep the temps good. Tuning window is a bit smaller so the needles need to be more precise. Definitely less power with 12%, but the engine will run fine.

[@henriksrensen3220]

@kings-racing Thank you for your answer 👍😊

[@MrBoomtheroom]

how does it compare to a ad2 and ad3 engines?

[@kings-racing]

This engine is totally different so i expect it to run different. I really like the ad engines. Looking forward to run this engine and experience how she runs.

[@henriksrensen3220]

Hi. Which FX engine would you recommend for bashing? I have returned the O.S max B21, Thanks in advance

[@kings-racing]

The os max b21 would be good. Specially for the price. FX engines are pretty expensive. The gt engine (G501 or G501T) is 500 and 600 for the combo. Those have a lot of power. A offroad engine (K303) is 460 , K502 480. And + 90 for combo Considering you run 12% i would pick the K303. It idles better than the gt engine.

[@a2rc]

Thanks for the great walk through Kings 🩵 So, are you making your own songs/music now? I meant to ask a couple videos ago What does OS consider this engine? - All out race or something a little less than that? It has some nice features (slug in crank, DLC, great head, etc) but, then it has other features that could be a bit more dramatic (ex the sleeve porting). Just wondering your thoughts Thanks for another fun vid 🩷

[@kings-racing]

Absolutely my pleasure ! Yes, making my own music. Don't listen to it to much or you will be screaming OS & B21 all day too. This is definitely a race engine. With the parts used in the winning world championship. There is really no need for fancy or dramatic features to give the characteristics you want to a offroad engine. A basic three port design with timing numbers complementary to the other factors is al you need. Appreciate the comment and thanks for watching buddy

[@delawarepro3539]

Please review DP’s Ultimate engine 🏎️💨 DP is getting 11+ minutes on a tank 😳 Thank you King 👑 👌

[@kings-racing]

Sure 600 bucks. Just bought two engines and another one on it's way. I do really like those square engines and that one is looking very good. Curious what they changed from the regular mxs. Thanks for watching brother 👊

[@delawarepro3539]

Do you break-in your own engines? What are your thoughts on not using ebis service and going old school route?

[@kings-racing]

​@@delawarepro3539 i always break the engines in myself. I can inspect them and i think it's better to do the break in with everything at operating-/fluctuating temperature and load instead of a oil bath.
