[@VisioRacer]

Thanks for watching guys! I hope you have learned something new and interesting. Cheers!

[@M.asa.]

VisioRacer love the vid and yes I learned someting

[@XIMXDAXBOMBX]

VisioRacer You need a better mic and also need to remove the static noise when you talk.

[@stephenwever]

you forget about semi peripharel port where they combine peripharel port and the side ports these are the ports the drag guys use to make over 1250 rwhp and runs 6 sec in the 1/4 mile

[@hfvjjauregui8548]

Saludos desde México muy buenos tus vídeos

[@RealKaiserBelial]

VisioRacer you improved much. its much easier to understand than before

[@BoostLust]

" more powerful and less daily drivable " that's the definition of #RaceCar 😂 Nice video bro. Keep it up.

[@brysonmerrell575]

BoostLust Hey! I follow you on instagram!

[@BoostLust]

Wassup my dude ! :DD

[@Rebar77_real]

Engine porting is always super fun! :D

BSHAWofIT underrated comment

[@samiamm5764]

Missing my 8. More smiles per mile than any car I've ever driven. Did so much canyon digging in that car I'm still smiling 5 years later. Did three cross country trips in it, twice to Florida and once up to Niagara Falls by way of Michigan and always drove non stop gas-n-go. After 35-40 hours of being on the road without sleep, I'd be hallucinating some of the most random stuff but I'd still wish there was more road to go

[@timpos546]

You really don't need the subtitles, i understand you perfectly fine :)

[@VisioRacer]

I personally like them there, I like to read while listening sometimes even in my native language. Dunno why

[@user-mn5sd3sn8z]

VisioRacer i need subtitles

[@xXCraZyCarLoS13Xx]

timpos546 they are very useful for people like me, which english isn't our native language 😌😌

[@ethanlopez109]

Thx for the subtitles VisioRacer

[@Gohsted]

Sometimes I'm at work watching these videos audio isn't an option in the workplace so keep them

[@mingscustoms]

Comment on the reliability part, mad mikes 4 rotor fd has had the same engine for the past 3 seasons and has not needed a rebuild

[@gamingmadesimple5510]

and he is putting down 1000hp in all 3 of his cars... I believe the miata with 26b is up to 1250 or 1300, FD is right around 1200 and the rx8 is 1100... all have 26b engines all tuned for different race limitations.

[@Bonkatronicks]

no way fd only making 500 - 700tops

[@jeztime147]

The FD is only making about 600 as its naturally aspirated, i believe the rx8 is making somewhere around 800, and the mx5 is making 1200

[@gamingmadesimple5510]

really? last I thought I had seen everything was in or very close to breaking the 1k hp mark... i'll have to go check out what they are at now

[@gamingmadesimple5510]

ok just checked the current figures for the cars... RX8 is 812bhp and the RX7 is 537bhp. all 4 rotar the rx7 is a NA build but they are building it up for a turbo setup.. building it all up first then the turbo(s) will be the last thing put on and yes the mx5 is 1200bhp but it seems he is no longer using it at competition drift level

[@rADIOLINJA]

This video was really interesting. I haven't really looked into rotary's N/A tuning so this was new stuff for me. The tuning methods seemed somewhat similar to 2-stroke engine tuning.

[@NFSGamerful]

excessive noise... that's not a con for me ;)

[@VisioRacer]

Not for me either

[@NFSGamerful]

Imo the 2 rotor is one of the best sounding engines

[@franciscodieguez5187]

It is only for the neighbours... unless they are car people too.

[@initialdfan8352]

Me neither

[@Emp210488]

[@_monti142]

your voice is getting better every video. im getting used to it lol

[@fishscalesexican2962]

i slapped my laptop cuz of your picture

[@JM8686]

proud owner of a fc rx7 brap life forever 👌 great video tho

[@stiffygoats5337]

So glad someone finally made a entertaining video about how rotaries work!! 👍

[@scottyd2262]

I learned alot from this vid. I've always been a V8 guy but I also love RX2's because one of my mates had one monster port / fuel injected Having a ride in in made me feel like I was on my CR250.. Great little cars !

[@porkchopgaming8480]

I love his voice and accent it reminds me of a younger Alberto BIGBOOST💪💪💪

[@mr.sandman5311]

I really like the sound of the extended port. Great video.

[@xMobius1x]

Great video, learned a lot. Keep up the good work, your English is really improving. Been following your videos for a year or so :)

[@zale126]

is it just me or is he getting considerably better at speaking in these vids? it seems like good practice! keep up the good work bro!

[@alejandromedina-ix5yx]

cool to see that this is not just an other video explaining how a rotatory works, thank you for trying something new. i have a lot of faith and respect for you, keep the good work. (sorry for bad english)

[@perrycollinss]

This was very well done! I'm gonna come to your channel more often cause of this

[@SilverLightningXV]

This channel has come so far since I found out about it back in 2014! Keep up the good work :D

[@VisioRacer]

Thank you!

[@wolfmannn2008]

I'm so glad seeing you gain subs, your vids have been entertaining me for a long time now :)

[@seanparker96]

at last, more BRAAAPPPPP BRAAAPPPPP BRAAAAPPPP

[@garrettchappell3786]

Thanks. Answered all my questions!

[@joediertay2434]

thanks for the rotary video finally!!

[@edgarsantiago_3908]

Great video with lots of good information. Something about those rotaries has me hooked 🔺💯

[@Runkization]

That sound is amazing

[@McFreeStyler93]

There is two answer for this matter 1.Someone asks for rotary engine work 2.Visio has Rotary fetish My personal guess- both.

[@blkdna748]

Sharing a ton of rotary knowledge thankyou.Rotary lover

[@MyrKnof]

That last white FD really sounded like the 787b. Very, very nice. Is too bad wankel haven't been researched as much as the conventional engine, so we might have had more of them.

[@0268race]

Bro your english got a lot better already! I love the new vids even more

[@lilasiankid214]

I learned something. Great video!

[@wonkylommiter6364]

The best sound man has created so far.

[@Shreddiespaghetti]

great video! well done man!

[@VisioRacer]

Thanks

[@isaacl.4452]

This videos narrative was very good

[@thestigsgermancousin4479]

doesn't matter what type of port as long as it has brappage

[@VisioRacer]

...which is you should go at least with the extended ports 😀

[@jonah.h]

bridgeports have a more aggressive brap than extended ports

[@samhaines8228]

well done Visio!

[@aronoosterman2038]

another good voice over

[@scwarzewaffe85]

What a fantastic video.. easily on a par with anything from engineering explained channel. Trust me vis.. that's high praise. Good on you.

[@VisioRacer]

Scott, thank you very much!

[@kylarobichaux7432]

IT SOUNDS SO NICE :]

[@staircast]

Great video!

[@zacharyfunair1974]

Good video, keep up the content.

[@cristianr3712]

Nice vid, love that 26B

[@REVMedia]

Great information, thanks!

[@ramrod126]

Your english is improving at a rapid rate. Keep up the great videos.

[@StevenYang506]

This was very cool!

[@giorx5]

A very rare topic with a great way to explain and show differences between the types of wankel engine porting.

[@Dutub2000]

This was really interesting and since I haven't read all that much about rotaries, I learned quite a bit.

[@tiagoribeiro6361]

Great video ! keep it going ✌👌

[@blackheavyblans]

I love the bridge port brapping sound.

[@mp2956]

Thank you. Very interesting and informative vid.

[@barenstil5525]

this video was really educational for me, you could do these videos more often since they're pretty fun as well! and mate you're going to reach that 1 million subscriber mark one day :P

[@VisioRacer]

I'd be blown away if so. Thank you, buddy!

[@MrFroggyMan]

I want a rotary

[@aidanevo]

FP5Reviews If you take care of it it'll take care of you

[@godfreypoon5148]

I have had both rotaries and pistons since I started driving. I hate piston engines, they're like having a girlfriend with no tits and short hair. Fucking lame.

[@MrFroggyMan]

FP5Reviews people told me not to own a 2 stroke that I would regret it and I don't so hm I'll take my chances on this too

[@herculesrockefeller2984]

You dont want a rotary. They could hang with piston engines in the late 80's early 90's but after that they were garbage. With today's performance of piston engines there's literally no reason to own a rotary. They are weaker than a 4cyl, they eat gas worse than a V8, and have the reliability of a Ferrari. Rich kid fan boy's who are trying to be 'different' are the only people who think rotaries are worth a damn anymore.

[@justinl1829]

Hercules Rockefeller Rotary Engines can actually provide better weight distribution when compared to piston engines. :)

[@EstevanTH]

For sure you did some great research, this is amazing! I did not know about those details, probably hidden over the Web, and you found, I guess, most of what you could find. *applause*

[@JParkes43]

Awesome video

[@jordi925]

great video I love rotarys

[@RobertGriffith9]

The p-port RX7 at the end has a different engine to Mazda's R26B. In the RX7, the rotors have a 180° timing difference, so each pair of rotors has their intake, compression, power and exhaust strokes simultaneously. The Mazda R26B had rotors at 90°, so at any given time each rotor would be performing a different stroke. Mazda's setup decreases the instantaneous torque application when a combustion stroke starts, making their engine 'smoother' due to increased power stroke overlap and less likely to fail due to lower stresses on the eccentric shaft and transmission (or transaxle for the R26B).

[@bengraves9416]

I love all the rotary love. ❤️

[@gen3v8]

Well done Sir.

[@pauloferrarezfilho1291]

This vid just made me a bit more anxious for the finish of Rob Dawn's 4 rotor rx7

[@VisioRacer]

I don't think there is the need for anxiety

[@pauloferrarezfilho1291]

VisioRacer well, all we can do is wait, so patience then :v

[@gaborangyal338]

great vid, especialy that you included an engine sound video for evry type of ports

[@LeLutinBanni]

Amazing vid

[@jollytas]

That's my car at 3:45 and 4:09. Also the idle when talking about extend ports.

[@Kristo99]

haven't even watched the video but still liked it!

[@andresavila8620]

Nice video, very interesting 👌🏻

[@perrosdemaiz]

Awesome!

[@LeadFootash23]

Nice video, really helpful. I've just uplaoded a video of my friends bridge ported rx8.

[@marcotruitt19]

Very educational

[@sebastien1664]

video about my favorite engine!!!

[@Ja5Productionz]

Thank you!

[@william94743]

you're getting better and better in you're pronatination. keep up the progress! maybe it's an idea that when you have a bridge port. there will be a different manifold mounted where a valve is placed which opened only at a certain RPM. so it will have the peak power. but still be driveable and decent fuel economy?

[@bingwrite]

Considering I just got my FC RX7 Last week... I think the rotary gods are telling me something ;)

[@edwardlorenz3437]

very nice

[@bukanbrewok]

great video! please make another wankel knowledge-ish video like this!!!

[@El_Chompo]

Awesome video. Rotary love. I learned a lot about all the ports. Now I'm imagining a rotary with variable port geometry, just like VVT for cars. I know it's possible, but would it be worth the cost.

[@mk3eric]

nice video👌

[@stoneburier]

nice video thanks

[@Fixed_Sprint]

spinning Doritos.

[@stevehedges6749]

love it ! ;D

[@DanMarcelino]

Braptastic!

[@chadburg86]

great outro song.

[@alberthalle7348]

Wouldn't consider excessive noise a con lol Great video man

[@craig19721000]

Good vid long live the rotary engine

[@antoniocatalano9661]

damn bro nice video rewiew of one of the Best engine ever the rotary engine sounds so damn loud But the only problem was the reliability but as always good video ;-)

[@CapnFlappyJaw42]

Making me miss my FB, man :(

[@Nelis1992]

Seems similar to 2 stroke porting. Good video

[@adrianbott1108]

I was lucky enough to be the first guy (or girl) to overhaul a Mazda rotary engine in New Zealand back in 1971. The car was a R100!

[@talipmalkoc988]

Thanks to you

[@Lionchuu]

I have a mild ported FD. It has a smooth idle but braps on half throttle when cruising. :)

[@VisioRacer]

Good to know, nice!

[@numberninelarge3121]

awesome vid im thinking of getting a 1st gen rx7 as a beater/budget build are there any other mods u can do expect forced induction of course

[@sambaldwin7715]

at 5:00 that guys put a rotary in that ancient corolla👍

[@Complextro93kg]

Video about lada and their rotary engine :D White rx7 is monster :D

[@kieranoconnor0]

Omg that 600bho n/a white RX7 😍

[@Jorge-Tamacas]

Interesting video, I just learned a little more about rotary engine. Actually I'm a fan of it, The sad part is: in my country is a strange and hard to work engine. Anyway, interesting video. Greetings from El Salvador

[@khadafiyusuf1917]

Bridgeport 😍

[@ricardopenedo5786]

The last Rx7 that you showed on the video is pure sound, 4 rotor. I wish thy were able by regulation to bring engines like that. Just bring up the unlimited rules of good old times. Keep the safety for pilots but let the rest unlimited...

[@flavioks5438]

Oh so that’s how that beautiful idling sound is made

[@jonah.h]

yeah they don't brap stock

[@coolmanred]

paradne video :)

[@VisioRacer]

Vďaka :)

[@srasheedgtr]

'The larger the port you go for, the crazier you are.' I guess I'm pretty damn crazy then. Peripheral porting for me anyday.

[@zOiNhUh]

Now you got me wondering if some sort of power valve similar to the YPVS could benefit a ported Wankel.

[@jaymetua6399]

Sik video we from New Zealand love rotaryz rotaz on tokoroa
