Awesome Brother.Its Great that you and King's Racing are carrying on Rex Way of Measuring blow down and getting your Numbers 💯 percent perfection!! Great review!! 👊
Thank you! We learned so much from Rex. Still learning, trying to understand about nitro engines. I wont spoil but Kings is coming up with something awsome, he will take is to another level
30 degrees blowdown is a good number . the way I get the number is exhaust from open to close say 184 and open say 124 then you half both and subtract one from the other that is the blowdown. its interesting from big 2 strokes all the way to the small ones the timing stays the same . I used to build drag racing scooter engines for a living and have been porting my own nitro engines for 30 years or so. there is always room for improvement but the blowdown is most important for a good running engine.
It would Be total duration open. so as piston is coming down as soon as you see light at top of port window you set degree wheel to zero and run it around back up to close and that is duration open. same on transfers. the crank same way at open set gauge to zero run back around to close and that's the number .Really like your videos. @@TastyBRC
Nice one! I forgot they still made the XRB love those 21j carbs one of the best carbs on the market in my opinion. Should do your own mods on the XRB than compare it to the Ielasi
You can use soda pop can aluminum to make shims also under the sleeve. just trace around the sleeve with a exacto knife on a sheet of can side then slide sleeve through and put it in the case then trace the top and it will pop you out a perfect shim. each shim is 3 thousandths. I made a dynamite 19 really run well with just adding 2 shims and having squish at 6 thousandths in a outrigger boat. its unbelievable fast.
I use regular head shims under the sleeve, I use my dremel and a bit of patience to enlarge the shim. Did that with my Ultimate m5 you can check the vid
Great vid 🩷 - I wonder if the blow down numbers are doubled because there are 2 transfer ports ⁉️🤷🏻♂️ Maybe that’s why he doubled the numbers? Not sure. - The engine is still nice and should do well (especially if you take some time to do some mods). If you are going to mod it, run it stock first to get a feeling for the engine. Then later mod it to have some comparison.
Thank you, I rather think that it's some kind of 360-180° thing, maybe his software was measuring by 180° wjile we use a 360° wheel but in that case we should also get different numbers on the crankshaft but we get the same open and closing numbers... It will remain a mistery, sadely. The plan is first a comparison vid with the dusty, then try it stock, next modded
hey man i know you had some doubts about the nova engines, but i recently just got a B3R and every issue that you had with yours (along with some of the other issues other people have had) have been fixed. The weirdly tight tolerances on the crank are fixed, the piston and sleeve are much smoother and didn’t have any scratches or anything, the dlc on the crank is much much better, and they updated the cooling heads and they’re way better than the original design. The only thing that hasn’t changed is that there aren’t weights in the crank. If you still don’t have a desire to get one, i don’t blame you, but they are far better now than when they first came out
I hear you! I will definitely consider this and maybe give them another chance, maybe.. I have to admit that Im very curious about the T6 .24 truggy engine
I brought this motor brand new an yes it was the cheapest os here in Australia 🇦🇺 bro they are great starting point especially for breaking in great review bro 🤜
Same here Tony, this Engine is available in Germany for 175e !! is true that back in time you could buy a nice novarossi p5 or Paloma for that price but nowadays, I think this is the best deal for the price. Thanks for stopping by !
I was planning to try different venturis and make a fuel consumption test also try this engine in my GT as O.S. also sells this engine with a onroad pipe as a GT combo
Merci pour la vidéo c'est cool. C'est un bon moteur que je roule en GT8 loisir et honnêtement il fonctionne déjà pas mal.. J'attend de voir la suite sur ce moteur et je me lancerai peut être dans la préparation du vilebrequin et la chemise (j'ai jamais fait ça) 💪.
Ce moteur est vendu en combo avec échappement GT, je pense que c'est une bonne entrée de gamme pour la GT du fait de la fiabilité et facilité de réglages. Je pense le tester aussi sur le GT 👍
@@TastyBRC It should respond pretty good to mods, but a quick warning to be careful with the crank though. Even though it’s a like a blank canvas and is super tempting to start hacking away at it and putting all the cuts a high end race engine has, taking off too much weight for the crank will make it seem super snappy on the box, but once the wheels are on the ground and there’s load on the engine, the engine can tend to bog down or make less torque because the crank doesn’t have the same amount of rotating mass that it used to to help push through the load on the engine. An engine with smoother throttle response, but still makes torque is going to perform much better than a super snappy engine that bogs down under any sort of load. Speaking from experience here. I’ve done that to a couple cheap motors that ran great stock, but still had room for improvement, but I took the “improving” a little too far 😅
D'aprés ce que je vois c'est un moteur pas trés puissant mais avec une bonne finition donc robuste pour du loisir sans soucis, dits moi si je me trompe

For it to be the cheapest o.s. engine it's pretty nice to a basher like me ..real nice break down of the engine and info..great video bro 👊🏿
Thank you! A basic engine but good quality, perfect for a basher but also a good entry level engine for racing!
Looks like a very nice engine. O.S. quality!
Very nice for the price ✌️
os has got crazy with their prices!!!
This one is affordable but very basic, the high end OS are very expensive but you cant go wrong with one of those
Great vid again buddy.👊 Looking forward to the comparison 👍
Thanks 👍
I used to ramp and fang the port, take a little off the crank and it became a beast......
I am planning to that soon 💥💥
We run this at our club for 1/8th club engine class, bullet proof engine...
great review champ🤩🤩
Appreciate it
Nice going through 👍
Thanks 👍

Very interesting ! Our method to measure the blowdown doesnt take into account how large the exhaust port is, yours seems to if I understand well.

Hello Yes 30 is good number
Also can widen exhaust port for over rev.
awesome bro looks like a fue cuts in that crankshaft will most definitely help.
Yes it will! But going to try it stock first!
Jolie ce petit OS 👌
Plus qu'a attendre de voir comment il envoi 💥
Très bien pour le prix, un peu de dremel et il roulera beaucoup plus fort, ça promet des vidéos intéressantes
Oui il est pas mal ! Pour le prix et la puissance annoncé, je trouve qu'il fonctionne vraiment bien, je l'utilise en GT8 avec la bise de 7mm
I stared rc 2 years ago running o.s since I got a nitro, I have no idea why no one brings this motor in except greed
I have seen some people run races in my country with this engine, and they are competitive!
Nice one! I forgot they still made the XRB love those 21j carbs one of the best carbs on the market in my opinion. Should do your own mods on the XRB than compare it to the Ielasi
Thank you. That is the plan, I will try it stock and modd it later 💥

@@TastyBRC one of my buddies at my local rc track has the T6 .24. he hasn’t run it yet, but i’ll let you know how it runs when he does
Music is unnecessary… Great content 👌🏻🏎️💨
Thank you

@@TastyBRC I hear you bro the are $275 Australia 🇦🇺 which is very cheap about the same price as a lrp .28 👍
When you run it, try both venturis in your buggy, Maybe with the GT venturi runs better.
I was planning to try different venturis and make a fuel consumption test also try this engine in my GT as O.S. also sells this engine with a onroad pipe as a GT combo
That’s a cheap one? Very respectable.
Under 200, probably the best choice for this price (nowadays..)
Merci pour la vidéo c'est cool.

@@TastyBRC oui je suis d'accord avec toi la dessus, tu as le coude en 75mm ? J'ai monté un 70mm et j'ai plus de couple maintenant.
though the internals are quite simple, the engine has plenty of power and runs great
The Dusty gave an idea of how this one will run, sure I wont be disappointed! And I will have fun modding it.
