Rotaries are not cheap toys. But nothing angers me more than when a viewer messages me that a shop wants to charge a foolish amount of money for unnecessary mods.
Huge thanks to Valvoline for partnering to build the ultimate rotary. Their involvement allows me to push components past their failure point and share the results with you. #13b #rotary #teamvalvoline

I’m a diesel piston guy and in a way things kind of cross over as far as sealing combustion within the area it needs to stay In . Shouldn’t you clearance the side seals as well so you account for the expansion from heat and boost pressure ? My logic tells me the seal will expand in length and then bow out a little bit and press into the iron and wear it out

If the apex seals aren’t “crowned” (taller in the middle) they aren’t as good as oem.

i've never built a rotary engine before but i see that he tells us he misinstalled a turbo setup to not drain the oil from the turbo correctly and is calling that a limitation on the stock rotary engine. ghey af. pinging will kill basically anything stock or not.

The way he used the micrometer killed me a little..... Oh Jesus Christ. Other than that great video.

If I ever get a massive amount of disposable income and I'm still single, I think it's my destiny to have a rotary-powered vehicle of some kind. Preferably an RX7. There's something very special about those cars and rotary engines in general.

Every time I see a Rotary engine assembly video I wonder how the hell do the seals and springs stay in place? They look so fiddly and fragile!!!

Hey, Rob. Subscribing because Casey said good things about you in his most recent vid. I'm a brand new rotorhead. I've had this unicorn on my radar for about 2 years and finally pulled the trigger (check out that ODO! irpost.info/face/fy-lm-h-y/lJm2tKqxs5nei2o.html). I've been watching various rotary vids over that time and yours is the first I've seen showing how to do corner, side and oil seals. I'm not into doing crazy big power builds. I tend to be more or a preservationist but I might maybe someday Lord willing get another project rotary to build and restore.

Rob, there is no difference between a 20W50 and a 75w95, it's very much the exact same thing grade wise.

All those studies i remember well were done by Rafael,from Rafaelito racing from Caguas Puerto Rico back in the early nineties,when his 13bs keep on twisting and breaking the rear plate right on the upper dowel pin,were he found out he needed get extra dowels pins to stop the problem,may be back then you weren't even born!

Rob has watched engine builders enough and know thinks he can build a reliable engine himself... lmao... yeah ok...!!!
thumpin1 پیش ماه
And you haven't lapped the plates... LMFAO, Rob's building a handgrenade...! Did you check/clean all of those grooves in the rotors before installing the seals..? NOPE..! This is going to be comedy gold...! Can't wait, watching with anticipation... 🤣🤣🤣

Yeah my 85 rx7 has been parked more than 10 years because mazdatrix gave me an estimate of 6500 to rebuild the engine to stock specs, so 6500 for 100hp didn't set well with me personally, eventually plan on running something powerful don't really care what so long as it's fast.

Watching him not clean the side seals after sanding them and putting that dust in the rotor... probably not a big deal and I'm just ocd

Couldn't help but notice you are using the micrometer incorrectly as you tighten it by the tip only as it has some give when the correct pressure is reached. irpost.info/face/fy-lm-h-y/lmLJzsDQyKSepGo.html You might have damaged it to where it needs to be re-calibrated already. Now we don't expect you to know everything as you are not a mechanic, not a machinist, and a whole lot of other nots, but we do expect you to respect our different trades and learn them. Your very smart and capable thus most of us can see this shouldn't be a challenged for you. Your like a real life "Pretender" that is capable of learning many different jobs all in one person. I'd like to get that damaged rotor and take some detailed measurements as I think it is trying to tell us something about how it actually wants to be turned.

Rob, I've followed you for a long time and today I am subscribing to your channel. This is the type of video I love seeing from rotary enthusiasts. Thanks for everthing you do and share!

Hey rob how come you didn’t go with the rx8 rotors for a higher compression?

Mazda actually calls for superglue on the old 3 piece apex seals to help assembly.

The first thing you learn in Engineering or machining is how to measure and use accurate instruments. I'm surprised that anything you work on actually runs at all. But keep teaching professor......😂
