Glad to see you guys back at it. There are a lot of us who really appreciate what you do.

[@Koolicyde]

They said they had videos queued up for release - it was just going to be slower than usual.

[@bryce16710]

Agreed. I rather watch the non flashy ACTUAL car enthusiasts build, teach and just do things on cars. I don't dig the whole LZ, Hunt and others dudes like them. Call it hate or anything, Speed Academy is what I like to watch.

[@StoicBarber]

Personally I love build series it motivates me on my builds. Thanks guys!

[@RadDadisRad]

Definitely, I like the content that is a little more technical and less mindless entertainment.

Best channel on youtube for us track junkies and shade-tree mechanics.

[@kristophershaw9800]

its called under tree mechanic here

[@CDOES]

Solid intro! Short, sweet, and to the point. very well done. Edit: Really sucks about the engine. Hopefully itll go together good! Also loved the comedy sketch in the middle.

[@97skinnyboyswag]

Ha! Fancy seeing you here lol. Love the optics reviews!

[@CDOES]

@@97skinnyboyswag Hey Hey! Thanks mate! I see your a man of good taste in channels!

[@aAverageGuy]

The whole reason I got into watching this channel, because of the porsche engine and rotary engine build. always interesting to see something not the norm being built

[@TastyGnocchi]

Thank you for keeping on doing your thing, you guys create some of the best quality engine building content on KZbin, don't be diminished by the the few who complain for the silent majority of us will keep watching and appreciating your quality work 😁

[@harman7xhsh]

Glad to see you're back! And 10,000rpm fd will sound amazing.

[@Killerconceptz]

Rob Dahm is smiling in his garage watching this :). Ps keep the channel going your the best relatable channel on youtube, love you guys!

[@ThrottleJerk]

The man D.P. doesn't often work on cars but when he does, he wears a white tshirt and doesnt even get a spot on it. What a legend

[@Camhin1]

Guys, they said they had videos queued for their month off. They're not "back". FFS.

[@ryanmcandrews9343]

Glad to see another video. Especially a video with a rotary!

[@pierresauve8612]

I saw the last vid. I will admit I don't watch EVERY series you guys do but then again I flow in and out of almost every channel I sub to. But I've been looking forward to this series! Glad you're back!

[@jameskovacic4895]

Idk if this was edited after the failing video but everything felt much more concise and tightly edited, much easier to keep attention spans lol great video

[@d.mat.zero6525]

the commercial was awesome! i laughed a fair amount!

[@Pengajim]

My 9 year old freaking loved that Valvoline ad break.

[@PK-R]

Abosultly loved the valvoline cut scene! What a fun/smart way to advertise your sponsor

[@bobbyross2023]

Joe really does know his rotary, very good observation about the engine problems.

[@SilverSuperFox]

Thank you. My son just purchased his first 13b, in pieces, for his 1986 RX7. Now I can learn from you!

[@rtsoccerplayer]

They are not back yet. They said in the last video that they will still be releasing videos on a rotary build while they take a step back to re-evaluate.

[@cezelipatrick]

Can’t believe I’m going to say this but I loved the advert in the middle - usually I’m deathly against them but it was fun. Great video as always!

[@868drive]

Thanks for coming back guys. Speed academy for life!

[@trizio4248]

Taking time off after engine blew up ... Next up rotary engine rebuild. Love the ambition guys!! Way to double down. I really love you content. Wish you guys the best success.

[@antbymcnair4297]

First "real" commercial in KZbin history! lol and it was awesome.

[@sti-uk9033]

Brilliant to see you stick at it, love the spin on the advert on Valvoline, hate ads but this made it fun!

[@Cheo.M]

Yes!!! Rotary content

[@mmavcanuck]

Excited for episode 2! Even watching your rx8 videos, these engines are witchcraft to me.

[@raynaidu2500]

Good music, interesting topic, beautiful production. Well done!

[@chrisbradley8162]

What is the music? Its mint

[@michaeln.7083]

Vacuum nest!!! I was a rotary mechanic at Mazda for 4 yrs.. I loved them then hated them.. I used to replace the vacuum lines with aircraft line to reduce cracking 100% and help with longevity...

[@I_know_what_im_talking_about]

How are aircraft lines different? What are they made of? Cost? 🧐🤔

[@elvincastro9479]

The most informative channel out here I love this content and really appreciate how much detail is put into the videos

[@shyguy4no1]

0:21 I see you have not skipped leg day. Awesome. Ok back to the build I am giddy about this.

[@iwantoffroad]

in my high school auto shop we had a rotary engine on a table like that. some idiot bumped the table on accident and one of the irons hit the floor and damaged it. love the new build excited to see this

[@literallyanythingelseother]

This brings me back, it was your old 13b rebuild video that got to subscribe in the first place. I thought I would have to rebuild my motor but she still going strong lmao

[@Aphexic]

Guys this editing and cutting is soooooo good, it's so much better and to the point !

[@bartp7280]

Nice!! I LOVE the new intro! I was so happy to see a video from you guys in my subscription feed

[@minilurk11]

Guys this is one of my favorite channels. Actually informative and not your typical "influencer" type channels. Absolutely love it

[@of_lion22]

Alright guys, I'm 1:30 in and so far, excellent work creating the engine stand montage. Much more visually appealing than a static shot. I enjoy watching Pete when he's on camera but, the combo of Dave doing work and Pete getting more creative with his filming looks like a good combo. Nice work guys. So glad to see the rotary build going! .....nice Mustache Peter. Suits you well.

[@Ek9javier88]

Missed you guys, love the rotary content.

[@90civicsir]

lol, that commercial was awesome, the mustache and wig need to be used more!

[@Four_Eyes]

Dig the background chune, that a PremiumBeat track? Cool teardown, finally understand the basic anatomy of a rotary engine with more than one rotor.

[@JTheMoneyable]

Awesome commercial. LOL. You guys in costumes is something I didn’t think I’d see. Pretty nice pace to the break down. 🤙🏾

[@metalicsupra]

best auto yt channel period .

[@franciscovasquez4555]

Most weird motor, but informative stuff on the web. Keep up the great content

[@callmenyell9288]

Thank you for coming back.. We all appreciate you guys.. Don't worry what era you live there will always a car guy it never die.. Your video if not now will be appreciated if the future.. The knowledge you guys give us is gold.. Thats is why people will appreciated it.. Thank you speed academy..

[@pFbSpecV]

Well I'm back to watching guys! This is wild how the rotor motor are! I'm mind blown with the turbo system and intake manifold.

[@Kamukix]

This video makes my heart happy. I found out about Speed Academy because of a rotary video...and years later you're making my day better with another one. I'm so glad I stumbled upon you fine gents back then, it's been excellent ever since.

[@slidin86]

friendly reminder that RHD import rx7 the exhaust side is right behind the drivers seat. Prepare for massive heat soak into the drivers side cabin!

They've gone through all this with Ken's track rx-7 before lol including the swap to lhd

Great stuff guys. Didn’t get a chance to write some comments in last vid regarding feedback but either way I back your channel so much and the content you put out.

[@joe5962]

I know you guys probably won't read this, but I really appreciate what you do, as I'm sure many others do aswell. I only discovered the channel when you started the evo build, but you'll have my support on whatever route you take. Keep up the good effort guys!!

[@tomb3915]

So psyched for this build. Had 2 fc rx7s and always wanted to rebuild one but never had the guts to take it apart. And the fd is one of my dream cars i will be watching all of this build for sure.

[@DavidHuntOKSO]

Great to see a rotary rebuild. Don't rush the details with too many fast forwards.

[@72Birel]

Looking forward to the next Valvoline ad spot. Good stuff.

[@nottabuild]

love the content please never give up this channel is my favorite place to come for jdm content :)

[@y2ksierra]

I briefly owned a rotary car. While I don’t miss it, it’s very cool to see this engine taken apart.

He's still building it lol. You can follow him on instagram @_ken_spec_

[@uniquelypositive]

Great video. Love the rotary... The simplicity, the sound, the size... Looking forward to your next videos. To everyone who is reading this, click on the ads that come on during the program... Support great content and sponsors.

[@arrivendrive6831]

Love that rotary content. The rotary content is what originally lead me to subscribe to this channel. It is obvious that the last build on that motor was done very poorly. These poor builds is what makes rotary engines not reliable. Many engines are done like this and then the motor gets a bad reputation. The builder of the rotary engine is one of the keys to a reliable rotary engine. Well hell I guess this can be said about all engines. I am sure that speed academy will do it right and it will be reliable. Brap on

[@Catbus-Driver]

The valvoline ad was a welcomed surprise lol

[@RetrowaveUniverse]

Yes there we go. Awesome video, this is the kind of stuff we all wanna watch tbh.

[@gar24407]

Just a crazy idea, making joint videos with other channels is a great way to increase exposure to new people to the channel.

Cool to see a rotary come apart. Looking forward to the next episode.

i love those milwaukee stubby impacts especially used with electric rachet they make short work of things

It’s insane to see the difference in complexity between my FC’s 13b and this 13bREW Crazy

[@ghostgaming7431]

Please SA make the other parts as detailed as possible and add things that we can't find online(tips and tricks). So far great start of the series and keep up the good work. I am hopping that this will be the one guide that I will use when I buy my rx-7.....someday. We rotary fans need to keep this engine alive. #ForeverFD3S

Yeeeesss you guys are back 😊, don't forget to resurface what needs to be 😛

[@tomjones5860]

Nice video! Rotary are awesome. Best channel on the youtubess interweb My theory, rotary engines complete “4 stroke/cycle” in one rotar rotation so 1.3L is really 2.6L. Also the engine has 1:3 multiplier gear inside so 10,000rpm output is 3,333rpm at rotar. 450hp/300tq 1.3L 10,000rpm is really a 150hp/900tq 2.6l 3,333rpm with 1:3 transmission gear. That’s why airflow, fuel consumption and heat are so different. :)

[@JoeySkidz]

Stoked on this series. I just bought an FD and an extra engine to build on the side ill be following this closely.

[@TheChindoboi]

Video content is top notch! Hope you're having a great break.

[@FreneticFreestyle]

been waiting for this one! also, i find it funny you glossed right over the fact that the flywheel nut is usually a massive pain, being torqued on to 300ft/lb. excited for the next episode

[@pw5415]

DIY incorporated vs. Pro's the the diff. would be cool and track days are boring to watch but i know its really fun. Commentating track days with a British style competition accent would be funny. Music is big. something more catchy and meeting pro drivers or pro builders is cool. Thanks i like the show I hope this will help to evolve the show.
