This time on Speed Academy! Dave and Ken observe the porting and sealing rituals of the Mazda Rotary Hammerheads, whose once great civilization was lost to less innovative and bold designs. Note the traditional song of the Hammerhead people, as recited by Dave himself. Remarkable. 😕😄

Rotorhead sayin' hello! Can't wait to hear this rip some braps

YES! i was really looking forward for more content of Kens RX7 build. Thank you guys! Cant wait to hear her brap!

I love these 13b rotary assembly/disassembly videos, they're loads of help. Can't wait to get my FD this year! Keep it up!

Sitting in Pearson Airport watching this!

Every time you put out a video on Ken's Rx7 I walk right out to the garage and work on mine. At this pace it will never be finished lol

lol we'll have to have FD battles if we ever get our cars running at the same time. V8 vs Bridgeport would be a fun comparo.

For Sure! U can drive the crap out of mine and review it too. I won't care! The problem is, v8 or 13b, it takes time to build anything properly :D

I just love rotary 😀💪

The Surgeon is back 😆

Ken is back! Yay!

I can not wait to hear it run

yesssss, can't wait to see this thing run. also in the middle of a bridgeport build myself so this is helpful 👍👍

It's really okay to show a rotary build again. As a RX-7 owner, I'm really disappointed that you didn't do a more in depth video.

Great job

Nice!!

Not my kind of engine, but they are very popular down here and they are a very interesting design. And, when it comes down to it, all knowledge is valuable - great video!

very nice

As awesome as rx7s and rotarys are, watching any rotary builds scare the crap outta me

it's witchcraft, for sure. Pretty sure Joe worships some strange rotary gods that require him to sacrifice a sheep or a piston engine of some kind.

Bunch of studs by the looks of it

Thx for the vid. Why not lubricate the rotors and housings when building the motor?

I saw a video where they said that for the final cutting of the side seal, they did it with the stone, and not just doing it to take off the burr

KENWAGON.!!!!!!!!

didnt know you have a youtube channel Dr. Ken. Love your build man, i wish you all the best and look forward to more videos on it!

Ken's hair lookin like it came straight out of an anime.

GR8 Video! Has anyone of you tested in bench, in a Mazda, a Sachs, an NSU Wankel RCE, the concepts by Kawasaki, patent US3848574, a wedge extension of plug hole, pointing towards trailing side of Rotor; or that by Toyota, SAE Paper 790535, a continued glow plug in leading plug hole site (example, a Webasto ignitor for heater)? Danke. Blessings +

Housings have chatter marks. , they need honing..lol

What about the three pieces Apex Seal, Citroën patent GB1438850, in a Mazda? Patent US1024504 is nearly same as 'Liquid Piston'; patent GB1260437 is for Nikasil coating, a German invention. Mazda once got improvements by using a 'wavy' Apex Seal spring vs the usual concave springs, but I failed in retrieving reference. Blessings +

Drinking game: Take a shot everytime Joe says "Uhh" Sent from the E.R.

So, this video is not on Ken's RX7 playlist but seems to be the latest of the series.. Any news on his project? Did it make 500 hp? )))

How long has it been since the first video in this series?

i only see two studs in this video if you catch my drift

Hiiiiyoooo!

Make up some dummy assembly pins with an internal thread - you can screw a bolt or, better yet, a fabricated "T" handle into it to easily pull it out if required. I've noticed elsewhere that some builders are using billet (side plate?) housing parts - I assume these would only be required for high boost applications? Oh, looks like a dry build - or the lubrication not showing up? On that, anyone using dry lube coatings?

a lot of vaseline is used, so its not dry

CNC porting is the way forward

what is the difference between bridgeporting and streetporting a Rotary engine?

Any updates on ken’s build 🤔

What have i missed, Rotary rebuild. What car is this going in?

DP is the only big stud in this video.

Needs more rotors

How can I contact you?

Why put the Vaseline on the irons?

J ported wow your engine must be for racing only and will not last that long . I know, have many mate’s here in oz with rx 3 even r100 with rotary engine

man... I pretty much know the in and outs and every part of the regular piston engine... but I know nothing about the rotory, other than how it functions.

Brew mance

What's the Frequency Kenneth? (1 in 25 people MIGHT get this...)

Mhmm rotary

Now make it a 3rotor....

what in the world is a bridgeport rotary

Kibbalittry

Mhhmmm

Motors are electric... Engines are internal combustion... And rotary engines are for Wankers !
