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
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
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.
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
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.
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).
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 !
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.
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.
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.
At 1:00, this video is wrong. Porting the rotary does NOT have "basically the same effect as porting piston engine heads". Porting the rotary is far more akin to changing the piston engine camshaft. You are altering exhaust and intake event timing and increasing flow. Though generally not adding huge amounts of CFM, it is more about the timing change unless we are talking about radical ports like peripheral. But porting a piston engine cylinder head does not change intake/exhaust event timing at all, only adding airflow. Confusingly the commentary then continues with correct information saying rotary porting changes intake and exhaust timing. One can also argue at 1:48 that it's not really easy to upgrade stock ports to other types. Oh sure, the actual grinding of the port is fine for someone with experience, but to access those ports means complete engine disassembly. The video also seems to insinuate that only 12As used stock ports at 1:42. Stopped watching after that.
Aaron, I did not say that the rotary porting is the same and only similar to the porting the heads. Listen carefully, I said that it is the same as the head porting, variable valve timing and big cams altogether!
I quote from the video and captions "Engine porting of the Wankel engine has basically the same effect as porting piston engine heads.". The next sentence is "What it does is it changes the intake stroke duration". Which insinuates that porting piston cylinder heads changes the intake stroke duration. It may just be an error in translation but the end result is confusing. I also just noticed that this video doesn't cover rotary exhaust porting at all, which is just as important as intake porting. In bridge porting you also claim that it pushes the rev limit to 8,000 revs at 4:43. Porting has nothing to do with the rev limit of the engine. That is set by mechanical balance as well as whether the engine can be controlled adequately at those speeds. Every rotary up until the S5 RX-7 had an 8K upper redline from the factory. Which was upped to 9K for the S5, then 10K for the RX-8. I just don't like rotary misinformation spread because there certainly is enough of it already.
I stand by my view it is a self-contradictory statement. But perhaps unintentional and just a consequence of translation to English. I keep watching more of the video though. At 6:48, you claim peripheral ported engines cannot idle below 2,000 RPM. Totally untrue.
Hey aaron, Love the Cosmo restoration so far. Good to see you pick yourself up from the robbery and continue working on the car. Keep up the good work.
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)
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.
A J port is like a bigger eyebrow that you'd have with a bridge port similar to the pic at 4:37, so it's more aggressive than a Bridge Port allowing for higher RPM, its called a J port because of how close it gets to the water jacket. A Monster port is what's shown at 5:28. It's known as a Monster port because the sheer size of the two heavily modified ports. Monster port engines are known for their short life spans.
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...
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?
I own possibly the cleanest ‘05 RX8 in all of Ohio and I REALLY want to Port it with the extended port. I need the BRAAP BRAAP BRAAP in my life! I plan on swapping the stock exhaust and the air intake anyways.
I'm surprised you didn't mention that the rotary engine was designed and conceived by German engineer Felix Wankel. Wankel received his first patent for the engine in 1929!
I would like to know what a rotary engine failure looks like, or exactly what you mean by "short engine life" of a peripheral ported rotary engine. Specifically, what parts fail and how?
Apex cracks or just fails out of rotor and damages stator( housing) and sideplates. As far as I know, after stator damage you would need to replace it. Or maybe it`s possible to repair it by welding and CNC milling but after it would require recovery of nitride surface. Rotarys are cool, but extremely expensive. Full repair set (before apex crack) of seals, apexes and bolts cost around US$1300. How much would cost repair in case of apex failure is scary to even imagine. If u`re on relatively low budget I`d recommend to stay with piston engines. Wanna lightweightness? Turbo`ed 1.6l can pretty easily achive 300whp. Or if you dont want to mess with turbo check Ford`s Duratek - 2.0l, great aftermarket support and weight of assembled block in range of 130 kg. With ITBs and agressive cams you would get same HP numbers as with ported rotary, and the same 1.5k-2k RPM idle. But it would cost much less to maintain. Or rover K-series 1.8l @ 120kg, Toyota 2zz-ge also very light (both engines was used in Lotus, and those guys love small weight numbers)
El KukS actually with modern apex as long as the failure isn't due to over-revving what usually happens is the apex seal warps causing loss of compression or the water jacket seal fails letting coolant into the engine. You can easily keep maintenance costs down by replacing the seals yourself it's quite easy to do
It's a myth, or misinformation if you'd like to call it that. Peripheral ported engines do not have short life attributed to the peripheral ports. They simply tend to have a shorter life because they are usually built as race engines and run hard to constant high RPMs to take advantage of the porting. All Mazda rotarys until the RX-8 had peripheral exhaust ports. Also way less people have first hand experience with peripheral port engines so they tend to just repeat rumors, assumptions and myths.
Awesome video visio 👌 That 26B is straight jizz! Check out the video of the extended port RX7 with the massive turbo on our channel. That thing was mental to drive!!
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
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
yoooo hahaha you used my footage that's sick haha. All I had was headers and a straight pipe to a 3A Racing muffler back then.That was before I blew the coolant seal. But I am going to rebuild with a port and a turbo.
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*
it was always explained to me that port work on a rotary is the same idea as a cam swap in a piston motor in terms of changing the power band of the motor.
A little off topic but there is a person local to where i live selling a rx5 with a blown motor. they are asking $4000 so my question is. what type of motor would you recommend to take its place and what value is the blown rotary?
Would it be possible to have a 4 rotor with mild porting and, say, 400 reliable, very streetable horsepower? Every 4 rotor I see usually sounds like it's tube ported
Just want to mention that extended ports do not give the famous rough idle. It would still be fairly smooth. Half bridge and full bridge ports are the first ports that give the rough idle
@@apismellifera1000 the renesis doesn't respond well to turbocharging because of it's high compression and the fact that it's literally made to be an n/a motor, not because it's a piece of shit.
Thanks for watching guys! I hope you have learned something new and interesting. Cheers!
VisioRacer love the vid and yes I learned someting
VisioRacer You need a better mic and also need to remove the static noise when you talk.
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
Saludos desde México muy buenos tus vídeos
VisioRacer you improved much. its much easier to understand than before
" more powerful and less daily drivable " that's the definition of #RaceCar 😂
Nice video bro. Keep it up.
BoostLust Hey! I follow you on instagram!
Wassup my dude ! :DD
Engine porting is always super fun! :D

You really don't need the subtitles, i understand you perfectly fine :)
I personally like them there, I like to read while listening sometimes even in my native language. Dunno why
VisioRacer i need subtitles
timpos546 they are very useful for people like me, which english isn't our native language 😌😌
Thx for the subtitles VisioRacer
Sometimes I'm at work watching these videos audio isn't an option in the workplace so keep them
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
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.
no way fd only making 500 - 700tops
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
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
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

excessive noise... that's not a con for me ;)
Not for me either
Imo the 2 rotor is one of the best sounding engines
It is only for the neighbours... unless they are car people too.
Me neither
defsqd
your voice is getting better every video.
im getting used to it lol
i slapped my laptop cuz of your picture
proud owner of a fc rx7 brap life forever 👌 great video tho

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

Is too bad wankel haven't been researched as much as the conventional engine, so we might have had more of them.
So glad someone finally made a entertaining video about how rotaries work!! 👍
doesn't matter what type of port as long as it has brappage
...which is you should go at least with the extended ports 😀
bridgeports have a more aggressive brap than extended ports
at last, more BRAAAPPPPP BRAAAPPPPP BRAAAAPPPP
I want a rotary
FP5Reviews If you take care of it it'll take care of you
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.
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

Hercules Rockefeller Rotary Engines can actually provide better weight distribution when compared to piston engines. :)
The best sound man has created so far.
There is two answer for this matter
1.Someone asks for rotary engine work
2.Visio has Rotary fetish
My personal guess- both.

That's my car at 3:45 and 4:09. Also the idle when talking about extend ports.
Great video, learned a lot. Keep up the good work, your English is really improving. Been following your videos for a year or so :)
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)
This videos narrative was very good
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.
This vid just made me a bit more anxious for the finish of Rob Dawn's 4 rotor rx7
I don't think there is the need for anxiety
VisioRacer well, all we can do is wait, so patience then :v
Bro your english got a lot better already! I love the new vids even more
This channel has come so far since I found out about it back in 2014! Keep up the good work :D
Thank you!
I really like the sound of the extended port. Great video.
That sound is amazing
Sharing a ton of rotary knowledge thankyou.Rotary lover
A very rare topic with a great way to explain and show differences between the types of wankel engine porting.
Making me miss my FB, man :(
This was very well done! I'm gonna come to your channel more often cause of this
at 5:00 that guys put a rotary in that ancient corolla👍
Considering I just got my FC RX7 Last week... I think the rotary gods are telling me something ;)
A J port is like a bigger eyebrow that you'd have with a bridge port similar to the pic at 4:37, so it's more aggressive than a Bridge Port allowing for higher RPM, its called a J port because of how close it gets to the water jacket.

I'm so glad seeing you gain subs, your vids have been entertaining me for a long time now :)
This was really interesting and since I haven't read all that much about rotaries, I learned quite a bit.
I love the bridge port brapping sound.
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?
haven't even watched the video but still liked it!
I have a mild ported FD. It has a smooth idle but braps on half throttle when cruising. :)
Good to know, nice!
I own possibly the cleanest ‘05 RX8 in all of Ohio and I REALLY want to Port it with the extended port. I need the BRAAP BRAAP BRAAP in my life!
I plan on swapping the stock exhaust and the air intake anyways.
Your english is improving at a rapid rate. Keep up the great videos.
Great video with lots of good information. Something about those rotaries has me hooked 🔺💯
Nice job
Donald J. Trump can you make the r34 and s15 legal ? :)
Toyota Corolla fan club nice fan club
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!
I'm surprised you didn't mention that the rotary engine was designed and conceived by German engineer Felix Wankel. Wankel received his first patent for the engine in 1929!
I thought that majority of people already know that.
I love all the rotary love. ❤️
'The larger the port you go for, the crazier you are.' I guess I'm pretty damn crazy then. Peripheral porting for me anyday.
I learned something. Great video!
What a fantastic video.. easily on a par with anything from engineering explained channel.
Trust me vis.. that's high praise.
Good on you.
Scott, thank you very much!
great video! well done man!
Thanks
thanks for the rotary video finally!!
I would like to know what a rotary engine failure looks like, or exactly what you mean by "short engine life" of a peripheral ported rotary engine.
Specifically, what parts fail and how?
Apex cracks or just fails out of rotor and damages stator( housing) and sideplates.
As far as I know, after stator damage you would need to replace it. Or maybe it`s possible to repair it by welding and CNC milling but after it would require recovery of nitride surface.
Rotarys are cool, but extremely expensive. Full repair set (before apex crack) of seals, apexes and bolts cost around US$1300. How much would cost repair in case of apex failure is scary to even imagine.
If u`re on relatively low budget I`d recommend to stay with piston engines.
Wanna lightweightness? Turbo`ed 1.6l can pretty easily achive 300whp. Or if you dont want to mess with turbo check Ford`s Duratek - 2.0l, great aftermarket support and weight of assembled block in range of 130 kg. With ITBs and agressive cams you would get same HP numbers as with ported rotary, and the same 1.5k-2k RPM idle. But it would cost much less to maintain. Or rover K-series 1.8l @ 120kg, Toyota 2zz-ge also very light (both engines was used in Lotus, and those guys love small weight numbers)
El KukS actually with modern apex as long as the failure isn't due to over-revving what usually happens is the apex seal warps causing loss of compression or the water jacket seal fails letting coolant into the engine. You can easily keep maintenance costs down by replacing the seals yourself it's quite easy to do
Yeap, I`ve heard people claims to run 13b for 300k km with good aftermarket apexes. But anyway it`s not that cheap as wanted to be :(
It's a myth, or misinformation if you'd like to call it that. Peripheral ported engines do not have short life attributed to the peripheral ports. They simply tend to have a shorter life because they are usually built as race engines and run hard to constant high RPMs to take advantage of the porting. All Mazda rotarys until the RX-8 had peripheral exhaust ports. Also way less people have first hand experience with peripheral port engines so they tend to just repeat rumors, assumptions and myths.
aaroncake the peripheral port in the case of the video refers to the intake port not the exhaust port
look up FOURRE on CZcams. it's a New Zealand FD RX7 that had a quad rotor in it in 2004 and ran a 9 second pass naturally aspirated
spinning Doritos.
Thanks. Answered all my questions!
Good video, keep up the content.
Awesome video visio 👌 That 26B is straight jizz!
Check out the video of the extended port RX7 with the massive turbo on our channel.
That thing was mental to drive!!
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
I'd be blown away if so. Thank you, buddy!
great vid, especialy that you included an engine sound video for evry type of ports
building a half bridge motor at the moment for my fd, should Brap nicely and get me close to 500 I hope 😎
Good for you!
Well done Sir.
great video I love rotarys
Keep the port small, and increase the boost... BAM!
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
I have a cross fed peripheral port that used stock 12a 6 port plates and ported 13b housings and revs to 13000rpm makes 340hp
Seems similar to 2 stroke porting. Good video
yoooo hahaha you used my footage that's sick haha. All I had was headers and a straight pipe to a 3A Racing muffler back then.That was before I blew the coolant seal. But I am going to rebuild with a port and a turbo.
Anyway, it sounds very nice. Good luck with your build!
Wouldn't consider excessive noise a con lol Great video man
Now you got me wondering if some sort of power valve similar to the YPVS could benefit a ported Wankel.
well done Visio!
Great video!
I've seen pp engines last year's what do you mean very low life span ? It's all in the build and how it's timed with maintainace
Nice vid, love that 26B
5:01 What excessive noise? Sounds perfect to me.
The only problem with the Rotaries that they have such a funny name. "Wankel" hehehe
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*
it was always explained to me that port work on a rotary is the same idea as a cam swap in a piston motor in terms of changing the power band of the motor.

Would it be possible to have a 4 rotor with mild porting and, say, 400 reliable, very streetable horsepower? Every 4 rotor I see usually sounds like it's tube ported
Me at the rotary specialist "I just want a mild peripheral street port pls"
great outro song.
Just want to mention that extended ports do not give the famous rough idle. It would still be fairly smooth. Half bridge and full bridge ports are the first ports that give the rough idle
why do the ports have to be big on a pp? if you make them smaller would it not be street able and more reliable?
love how the extended port is the most viewed lmao
Video about lada and their rotary engine :D
White rx7 is monster :D
Nice video, really helpful.
I've just uplaoded a video of my friends bridge ported rx8.
Great information, thanks!
Rotary's also respond well to turbocharging too
Michael Ellestad well the constantly flow exhaust so...
not the renesis motor though
@@JQNAH I know, from what I heard and read the Renesis is JUNK!!
@@apismellifera1000 the renesis doesn't respond well to turbocharging because of it's high compression and the fact that it's literally made to be an n/a motor, not because it's a piece of shit.
@@apismellifera1000 and also every rotary is a piece of shit, the rx8 isn't that special when it comes to unreliability
Why whith the peripherical port the engine Life is reduced?? And it's needed a new engine block doesn't It?
you missed a semi periphal port lol needless to say you mentioned some good topics on ports
