Machining the rotor down so it has "Room to do a hula dance if is has to", haha love that analogy. Yet another great interview, thanks HPA. There's just something about rotaries that is endlessly fascinating; so much bespoke engineering, so little factory support, and so many braps and flames.
That's what cool about them for sure. It's cool to see enthusiasts keeping them alive after factories have given up on them. Not to mention the power you can make with small capacity. Super cool
Agree.. like in between changing into different topic.. a bit nicer if got some short clips related to the topic before advancing into another section of the video... (Not neccessarily this video specific.. but in general video overall)
@@hpa101 Makes sense, but you showed a pass at 13:00, just showing it with full audio at the end of the interview would be great, or just an older pass would sufice, imagine you as a viewer, you get all this info about this great car/engine/setup and how amazing it is and then you don't even get to hear it or see it in action, if you could do that with every interview of this kind you do from now on.... that would be Great!!! Something like doing the full interview and then a short video of the car in action to close the video.
I like the questions DOCILE asks, it’s usually the questions many never touch on and he gets really “techie” when leading up to the questions DOCILE is about to ask.. Churr
I would love to see a video from you guys debating slicks vs radials, suspension geometry like IRS vs 4-Link and more information on things like Anti-Squat, Instant Center, Weight Transfer
the main problem back in the day were apex seals but nowadays with all the new types of materials they use and the new technology they’re getting more reliable and making more power
So what you're saying is, I could theoretically have multiple exhaust ports and a solenoid to open or close them so that the port matches the RPM for power at multiple locations, a lower and a higher rpm. It would probably cost way too much to develop and manufacture for the power difference it would give, but it would be pretty neat!
They do a similar thing on two-stroke engines where they use a piston (not an engine piston, but rather one like in a constant depression carburettor) to adjust the dimensions of the exhaust and expansion chamber to optimise the system for any particular RPM. The system you described would perhaps be more similar to the carburettors with multiple different-diameter barrels, each engaging at a different airflow. This is what causes some carburetted cars to sound fairly quiet initially and then have a sudden ramping-in of induction noise above a certain airflow. (Sorry for using two different carburettor comparisons; it wasn't on purpose! It just so happens to be where variable-dimension fluid piping is already used in the automotive industry)
Power valve for exhaust port Variable intake for the intake (obviously..lol) I think some youtuber did have peepee-port with variable secondary intake on his 3rotor rx7... Sorry cant remember who it was.. but definately not rob dahm or angel motorsport fella..
How hard to tune up rotary. Its very happy to see there are many kind of support for the rotary engine aftermarket. Thanks to wankel. ❤️ Rotary engine it's master piece of engineering.
Remove the bridgeports, saw them at 10:56, bridgeport are Rotary engine killers and they add little to no help with turbo ones especially when your up this high, thats why the Ricans are in the 6.1s with the 13B ;)
@@NikoKyunKyun 😯Many of the best ♻️Wankel Engine mechanics 👨🏽🔧 in the United States 🇺🇸 are 🇵🇷 Puerto Ricans who live in the United States, beetwen 2.2 million live there🇺🇸 on the other side, on 🇵🇷 “the Wankel Laboratory Island”🏝️
Yep, bridgeports may not be necessary with rotary turbo engines especially with semi-pp already drilled for more airflow. You may lose the nasty but ‘beautiful’ brap sound though.😉
So recipe is : Billet housings and plates, aftermarket seals that bend or warp instead of crack and break under detonation? You're still pulling the engine between events though. Why a CAS front cover instead of the FD front cover with a reluctor wheel, not super familiar with Microtech, does it require the CAS? Is it more reliable/less susceptible to interference? Here's a controversial question - why a Microtech vs a Haltech?
Tell John if he narks on us, we'll know..... 😂 Dudes like this don't really have a camera in their face day to day, being quizzed by something they don't know well. When you consider that, John was bloody awesome 🤘 - Taz.
Yep. For a piston engine to be that efficient on making power a Coyote 5.0 needs to make 5000hp. The 9.0liter stroker V10 for the Viper needs to make 9,000hp. That stuff just doesn't happen because, for one reason or another, it's just not possible without building a race spec version of those motors for Top Fuel NHRA level drag racing. That being said, a 1.3liter engine making 1300hp would struggle against any piston engine making 2000+hp for no other reason than the horsepower gap. This entire topic is SO much deeper than anything we could fit into a youtube comment.
@@beefcakeass different animals. This is a drag car that they disassemble and rebuild all the time. Sure Rob could technically make his power with a two rotar, but dang it would be a headache. Especially on a "street" car. Also, two rotar can't sustain that power long. They're running quarter miles, not driving a track or road.

one suggestion, show clips of the cars in action a bit more in between, I think everyone would like it.
This event was rained off sadly so there was no track footage to be had other than a bit of testing - Taz.
@@hpa101 that's understandable. But I suppose just keep the suggestion in mind for future videos eh?

Great content as always HPA! Love this stuff!
JBR, Microtech, Billet boss what a combo
I love these interview videos.
Unleash the full potential of the mighty dorito
the main problem back in the day were apex seals but nowadays with all the new types of materials they use and the new technology they’re getting more reliable and making more power
Hopefully be getting my JBR LT16C 6 second package and ignition setup in the next couple of months
Nice to see no blankets on it cheers boys 👌🍺
Seems like a class lad. Rotor power🤤

mazda already patented that for the new 16x engine
Its just like an adjustable runner length intake manifold
Power valve for exhaust port
Variable intake for the intake (obviously..lol)
I think some youtuber did have peepee-port with variable secondary intake on his 3rotor rx7... Sorry cant remember who it was.. but definately not rob dahm or angel motorsport fella..
Beautiful car, great interview, thank you ;)
Our pleasure Brian 🤘
Will be interesting to see results from Built2apex with his billet rotors and housings..

Semi pipi power...good job.
Notice the cas not trigger wheel unlike the fd3s and still 8 secs
Hey Taz! When are the beanies coming back in stock?
OUCH ! I LOVE IT.
rotaries = handle with care! FRAGILE
Looks more like a Dodge Stratus coupe than any Mazda 6 I've ever seen
BB Williamson family generations of engineering knowledge second to none in this space

The safe side goes for any NA 11.50:1 compression.
98 octane was hot and cold. 🤨
Timing
Ha ha Blanchy absolute fuckin legend!
If I win a lottery, I just gonna have my S4 NA engine built to factory spec with billets just to throw people off 😁😁😁😂😂😂
Big Lez
TIL semi pp > full pp lol
for turbo applications
Never go full PP. jk
Jon sounds kinda nervous or uncomfortable at times. Y'all better not be committing no crimes here.*Bullying is bad*

so when you are going to interview Rob Dahm... he's bullit 4rotar
Here's a Rob Dahm interview we prepared earlier.... 😉 - Taz. ruclips.net/video/pdeJu-qveEs/видео.html
And he’s achieved less power than the JBR 2rota lol having 4 “rotar” doesn’t make you special lol keeping it together is more of the topic point 😉
@@beefcakeass different animals. This is a drag car that they disassemble and rebuild all the time. Sure Rob could technically make his power with a two rotar, but dang it would be a headache.

@@beefcakeass Max power isn't everything. A bigger engine with less power means a lot more driveability and reliability.
You guys are standing so close together even I am uncomfortable watching.
There's not need to be uncomfortable Morgan. Everyone gets a bit jealous sometimes though I guess 😉 - Taz.
#RobDahm has entered the chat
Where 🤷♂️
🤦🏼♂️
Semi-PeePee 😂
i want to see the semi pp
semi pp,hehehehe
All thanks to pac racing made it all possible. And truly theirs only one name in the game pac racing its there brain's that made the first-ever
