Bro within the first two minutes... "Rotor 1 and Rotor two become Bank 1 and Bank 2" and I'm already floored. It feels like you're breathing new life into 2-rotor builds for real. I really wanna see something hooked up like this level, but in a transverse mid-engine build using like a built K series trans or something.

It's so counter-intuitive to run an engine that rich successfully. Rotaries are so fascinating.

[@RobDahm]

I’ve figured some things out that blew my mind. I’m testing them before I say much more but I figured out what was going on. I think haha

[@justRD1]

Use your EMAP to compensate for the 2 preturbo o2 sensors. O2 sensor readings are affected by pressure.

[@DomGrady97]

I don't think I've ever been so invested in a content creator's builds until I came across Dahm's content.

[@justinbarrera4377]

Pressure affects the wideband reading. Positive pressure will make a rich mixture read even richer than it actually is. You really need to read the pressure of the exhaust manifold of both sections to correct for the reading and\or verify the readings across both o2 sensors. I've done pre turbo wideband setups before.

[@unchartedgroupielove]

Assuming that would have to do with partial pressures of gasses each? Pretty cool you can adjust for it

[@robertcarroll5184]

DK from Garagelife tuned my FD, he's super knowledgeable and a great guy!

Congratulations on 1 million subs big dog. :D

[@K24Dryvr]

By far my favorite channel! My only request is that you spend a few more seconds shooting or explaining the tech side of things. I'd love to see the location of the new o2 setup. Really wanted to do a pre-turbo individual o2 x4 on my K24 but was afraid of burning up sensors constantly.

[@NO4Q2]

I was just about to go to bed. Finished the 4 rotor video now this video. Happy sacrifice.

You still need back pressure compensation for putting o2 sensors in the runners.

Also FYI 22deg timing on boost is WAY too much. Please dont use Dynocom dynos they are junk for repeatability.

[@anthonylove6639]

Hey Rob ever thought about makin a mid engined five rotary vehicle? Wonder if that’s possible. Be interesting to here what it sounds like at full bore!😱

[@lucky7s94]

Rob, I've always wondered if some of your tuning & spark plug issues revolve around what i believe is a flaw & phenomenon in the design of the rotary engine.. to give you a visual, place a rotor in a housing with the apex seal over a spark plug hole. Would combustion mixture leak past the seal at this moment into the expanding intake volume because of the plug holes? Surely the amount that gets past the seal varies with rpm and pressure difference on either side of the seal. Not sure if this is an overlooked phenomenon in the rotary world, but I figure this might be food for thought. Not sure how an alternative ignition source or solution of other means could be devised where it wouldn't allow for compression leak but if it is however possible, it would achieve greater efficiency.

[@iits_seb6976]

I think you have a point and I have considered this but came to the conclusion that the seal is moving so fast over a small enough area that the difference in compression if it were completely flat is quite low.

[@PwnOsaur]

Videos always blow me away Rob, really wish you'd invest in some hub dynos for your shop - bringing that in house would save you so much time even just logistically let alone aligning schedules with other folks, love your content as always my man ❤️

dude you have NEVER put up two videos in one day unless i'm mistaken... grats in general and specific

[@Turkeydinner]

I doubt you need to be told this but you can also read your timing on the plugs. There will be a defined line that works its way up and down the ground electrode as timing becomes more and less advanced. What a trip. Learned it on youtube troubleshooting my old westfalia. We don't have the modern data or even a wide band. Should check out "Gunsten Colortune" if you want real visual mixture feedback. Looking forward to the next one, dude. I've got a semi-pp rx3. No rotor? No motor...
