Bonjour. Just found your channel a few days ago and watched a lot of your videos and I really love it. Good job on sharing all your know-how and details on all the technial stuff. I just got into nitro cars with an MP9 tki4. I found the nitro motor HP claims unrealistic high, so I build a inertia chassis dyno to check it out. So far the stock MP9 motor makes 0,364 rear wheel HP. I ordered the O.S. B21 motor today and will dyno is as well and compare. If you are interested, I can make the fang mod to the cylinder sleeve and crank and dyno after, to see what power the mods make. Greetings from Denmark

Hej 👋 Thank you! I really appreciate. That is crazy! There are so many comparison possibilities with a dyno, My friend @kings-racing bought a dyno but sadly it's not working as expected, I wont get into details, I dont want to spoil. So your dyno works on 2 wheels, I think that you need to block at least the center diff to make it accurate otherwise the diffs settings will influence the results. Your thoughts?
@kristianmadsen1397 3 ай бұрын
@@TastyBRC Yes you are correct. I have locked up the center diff. and removed front drive shaft when doing dyno. I have spend a lot of time dyno with different roller size inertia, software and manual math calculations. I am confident that the hp results are true. But still the are wheel power. So mabye add 30-40% drivetrain loss like on cars to get the motor crank hp. But still a long ways from the 2hp ish claim :-)
@TastyBRC 3 ай бұрын
@@kristianmadsen1397 awsome, I would like to see that! Add me on mssger 🙏 Yes we are far from the claimed 2+ hp .. And even if you cant measure the drivetrain loss, it will be interesting to compare different engines and before/after modds Im not a kyosho expert, is yours the rtr version with a ke21 engine? If so the b21 will easily outperform that engine.
@kristianmadsen1397 3 ай бұрын
@@TastyBRC Yes its the KE21 engine. Looking forward to receive the B21. I should get it by post next week
@kristianmadsen1397 3 ай бұрын
@@TastyBRC This is really a great and powerfull engine. Is makes 1,06hp on motor where my ke21sp makes 0,79hp and it revs much higher so you get higher top speed as a bonus

@redsmagic4907 2 ай бұрын
I'm more interested in customizing a basic, low cost engine like this than in many complete engines. They are very expensive, so I feel it's meaningful to have a cheaper engine close to the same specs.
@TastyBRC 2 ай бұрын
You can get 2 of these for the price of a OS Speed and with some minor modds the max will be a very good race engine

That engine is looking really good. Basic, but definitely a good upgrade from the xrb. Good timing numbers. Could be 10 degrees more on the open, but pretty sure this is gonna perform really good. Think these are good race engines. Actually thinking why we spend a lot of money on the high end engines. Maybe you are better of (price wise) with a couple of these engines. Altough they probably won't last 60L like my fx 301. Anyway, great vid again my friend 👊
@TastyBRC 3 ай бұрын
Thank you Kings Unless you are a very serious racer, Im sure this engine will make you happy, you will get at least 90% performance of a high end OS for sure but yes I agree It wont last as long as a nice dlc engine. Rex said that the steel used by OS is soft and will wear quicker but the price of the complete engine is probably lower than a ad3 or b2104 Rebuild price
@takisdemi898 3 ай бұрын
Nice video! The xrb v3 version is in some stores €25 cheaper than the new b21. Tell us your opinion, which of the two is worth more?
@rcrelatedstuff6092 3 ай бұрын
That is a good question. Here in Sweden I have even seen pricedifferences up to 50USD
@TastyBRC 3 ай бұрын
Thank you 👍 I havent tried it yet but from what I see.. yes it's worth those extra 25€ Better sleeve design, higher numbers, improved cooling head and can be upgraded with the Speed series parts

@pierre-gillescoudert2569 3 ай бұрын
Salut Tasty, nice video as usual. Could this OS engine (or any other engine) be mounted on the MP10 readyset without having to mod the engine support block that comes with the kyosho chassis?
@TastyBRC 3 ай бұрын
Hello, if you want to install it in a rtr kit you will probably need to replace the engine mount. Rtr engine mounts are higher, this will allow clearance for the pullstart. You need the kyosho Race kit engine mount or the flywheel wont make contact with the bumpbox

Do you like the 22e carb better or the 21j?
@TastyBRC 3 ай бұрын
Hard to say! I tried both carbs but on different engines, to make a fair comparison i would have to try them both on the same engine. So cant really say about performance but they both tune great

Thanks another question has the crank in the xrb held up ok? Did you replace rod after break in?
@TastyBRC 2 ай бұрын
Everything is doing good. I dont replace the rod right after the break-in, i replace the stock conrod after 8 to 10L, always.
