It sucks that generic videos get more views than videos that are this informative. I love these videos.
I never realized how precise you guys are at building these Rotor engines. Can't wait for the rx8 build video
We do have one on our channel.
Awesome video, you Guys make some of the best rotary content on CZcams and some amazing engines!
Glad you like it
i assumed how this was done and this video is bloody terrific if anyone complains about cost of balancing show them this.
Well , I have been threatening to drive down to Calgary to get my 2004 RX8 motor rebuilt by you guys . I Bing watched a bunch of videos and it’s confirmed , I’ll be visiting you 👍
Really love your honesty and the fact of giving away knowledge for free. Just makes me want to buy a 13bt, was quite scared of them but watching the hours of vids you do I'd own one confidently.
Happy to share it and glad it encourages you
If I ever save the money for a 2nd RX8, you guys will be the ones I call!! Great video. Thanks👍
Your welcome
Very cool. Great explanation. I don’t own a rotors engine but watching you guys work on them is fascinating.
Dude! You are amazing!!! What a great setup you have access to at the shop. While it has it's imperfections you were able to achieve a perfect end result. Hats off to you man. And I'm hoping for a standing ovation in the comments.
Thank you for the kind words
Amazing. Cool to see the correct process. Keep up the quality videos 👍
15:48 I love how with enough experience, on measurements the human eye stops seeing millimeters and starts seeing "right", "not enough", and "dun dun dun, too much" instead.
Such a good explanation what is really needed on high rpm Rotary engines.... .Porting & Balancing
Nice job man! Quality craftsmanship
4:08 no, the answer is ALWAYS miata!!😂 jk love these in depth videos brother!
Excellent video! 👍🏻
That’s very impressive !
excellent as usual sir.
We love you Josh
Awesome video
Nice!
wow I always wanted to know how to do the balance neat
Great video thank star for sharing.
thanks no problem!
It is amazing
So far is to make a rotary engine finely
If you open a shop in Japan you can become a god
Shout out to Japan. Maybe one day...
Possibly the best Wankle video I've ever seen.
Glad you liked it
Some neat stuff there! Any benefit to include the front pulley, flywheel/clutch/pressure plate and thrust bearings?
Absolutely not. The best is to keep the rotating assembly using either the rear CW of the stock flywheel as a unit. If you balance an engine including the clutch and the clutch needs to be changed down the road, now your engine is out of balance. We recommend to only balance the with the flywheel if the FW is a stock FW as the counterweight is built into the flywheel. Most aftermarket flywheels and pressure plates are balanced on their own so keep those separate
Wouldnt having the the front pulley and the flywheel make this more accurate? Or are those parts factory balanced with the key in mind? Great video btw.
How is balancing different on the rx8 rotating assembly? I've read they are different because you need to consider the weight of the oil inside the eccentric shaft, is that true?
Not sure if will get an answer for my question but can a rotor be to modified or there is a limit of modifications done to a rotor
I wonder if there is some reasoning the RX8 rotors are not evenly balanced. Something to do with heat expansion at the part of the rotor where heat is most focused. Probably not and they just didnt bother to balance the rotors since its not an high HP aplication.
What is the purpose and type of application you need the rotor tip clearance? And also for the scallops and the combustion chamber? Thanks
Extra clearance on the tips is chosen because the tips of the rotor are the furthest away from the center line of the eshaft. If the engine undergoes deflection the tip will be the first to contact the side housing. Same with the comb chamber ...it is the furthest out portion of the rotors and this area can contact the rotor housing right between the spark plug holes. Scallops are for earlier port opening
RX7 Specialties I see. Thank you!
If you're lightening rotors, does it matter what their starting weights are? Is it any benefit to take an "D" or "E" over an "A" or "B"?
Yes and No. If the rotors have no lightening or mods and correction values worked out to be the same then yes you want to start with 1 letter apart. If the rotors have been heavily worked on then it doesnt matter as we can build the corrections back in and make them close in weight by the time we are finished
I'm interested in how you make corrections for the oil inside the rotors. Is it something you calculate or is it Mazda that give you the weight of the oil in there different rotors?
Good question. It is built into the equation when building the bob weight. We have done lots of testing and came up with weights for different types of rotors And yes it MUST be factored in.
RX7 Specialties so in the video, when you mentioned the high amount of imbalance you have seen in Renesis rotors, is this taking into consideration the correction for the oil? I've heard this before about the Renesis, which makes me wonder: how much of this imbalance (overbalance) was designed into the rotors from Mazda and how much of it is actually mfg error?
DEEREMEYER1 yes I was sort of hinting at that ;) If you had access to a large enough sample size of Renesis rotors you could do a statistical analysis to test the hypothesis (as well as get hard data on the mean amount) of factory imbalance
Great video
I guess the rotor weights matched before you started as you didn't mention any weight correction rotor to rotor
the main bolt tread is not balance, the tiny shaft seems to be unbalance,
Hello Rx7 specialties,
I have a short question... I live in Germany and there are not so many rotary experts and to find one is not easy, so I hope you can help a young enthusiast...
I want to buy a FD3S as a daily but with my luck I will buy the cheapest and wreckest RX7 on the market... So what improvements (like premix, or mechanical improvements) can I do to not destroy my engine after 2 weeks.
Thanks for your help in advance☺
Replace gas filter, ignition parts incl Lead coil and pre mix. if you dont have emission testing...get the catalytic converter out of the car and if affordable get a power FC or Adaptronics ecu
Very good video you made. Were in South Africa. Could you please assist me with the bob weight calc. I cant find any weights for the the oil inside the rotors. We also use the same Sunnen balancer. Or if you have a email adress i can contact you on. Regards Franswha
tru god of rotational combustion, none of thse other peoples hav thr balances such as one whom thus rec
Can you put a link to your website in the description
done, the website is also listed at the beginning and end of the video as well

👀👍✌👌👊🙏

Ty si z gramove váhy děláš pracovní stůl? :-)
Redo your latest video, it isn’t working
You do not tell what reliable Epex seals you put in so the whole engine assembly goes for a scam
