Kyle you seem to one of the most legit dudes I've seen behind camera. Honest and you actually care about the content and the rotary community. You are a legitimate resource to us all! I loved the video with you and Aaron from LSD. Thank you for all the content. As someone with a spare 13b at home this type of content is perfect and exciting. Keep up the good work !

[@KyleMohanRacing]

Greatly appreciate the support and kind words. Aaron is an awesome guy. Just trying to show what we have been up to 🙌 thanks so much

[@marsmars8857]

If your going to encourage this setup please show the process of correctly modifying the rotor .like a video when it's being performed with measurements!! So other machine shops dont ruin rotors..

[@KyleMohanRacing]

Its copying the RX7 groove dimensions. Only use machine shops familiar with the processes, or send them to KMR or Mazdatrix so we can do it right.

[@GrantMcWilliams]

Kyle, do you think it's possible to use this method to create a four rotor naturally aspirated Renesis hybrid? It's been said that this is the parts you use to make a four rotor (short) side port rotary. From front of the motor Series 4 ('86) front iron (sec port for number 1 rotor) series 4 center (pri ports for 1 and 2 rotor) 12a tallport center (sec ports for 2 and 3 rotor) series 4 center (pri ports for 3 and 4 rotor) series 4 rear iron (sec port for number 4 rotor) How about a Renesis or Renesis hybrid version for maximum streetability?

[@Johnwalter1044]

Absolutely want to watch this build! I remember seeing the first video where you mentioned the hybrid renesis. I was instantly hooked! I am worried though, i would like to see how exactly do you machine the rotors. I wouldn't want to destroy my own in the future.

[@KyleMohanRacing]

The rotor machining process is done on a CNC it's nothing anybody is going to do at home generally. we offer the service through KMR and Mazdatrix.

[@jonathanlam8029]

With this much content on it, I'm seriously debating pulling the trigger

[@rx8tom]

Would it be possible to go turbo power with renesis rotors in this configuration? Or would it be worth it to buy rx7 turbo rotors with lower compression?

[@KyleMohanRacing]

Check out the video series, or other hybrid videos. We talk about how we can figure it our setups and what works.

[@arcrotaryengineering7156]

I Wire cut the Rx8 corners, far better compression and strength...

Yep. Ive seen it done. 👍

[@matthewgendron3104]

[@jabadahut50]

the RX8's number 1 failure is the inner coolant seal failing. Would you say doing this to a street RX8 might help with it's reliability/longevity?

[@hauntedtreehouse423]

well fuck, already built and put the fucker in with racing rx8 apex seals with gsl se seals. i guess i just pray.

When you've got it all apart and ready to start, isn't it worth it to drill out the stud holes a little so you can use oversized studs? I was under the impression that added longevity to a new build. Thx

Kyle, have you talked about modifying RX8 housings to mimic the periferal exhaust port of the RX7 housings? There's the feature in that same spot in the mold, and it's just begging to be machined out

I have a Series 2 RX8... not sure if this will work for me? But I did call Mazdatrix and they sent me a parts list for my engine. But I need to know what I'll need for the fuel and oil system?

It will most likely be a custom setup, go larger oil coolers, racing beat race oil regulator... . I like using radium engineering for furl components.

[@yeahnah6468]

So keen. I recently ordered a hybrid exhaust flange. Although this flange has the center port blocked off, they say to avoid pulse interference. So I'm going to need a GSL-SE center plate or fill the renesis center ports with molten aluminium and run the risk of carbon building at the edges. 😬

[@KyleMohanRacing]

@@kingmaybus8409 Shafts aren't the problem. You would use a basic 20b shaft or short 20b shaft, but short shafts are weaker and not going to make any real power compared to traditional 20b parts. The fact that there are no side port exhaust plates is the issue. No one makes after market plates that are side port exhaust. And no one makes a 20b plate with side port exhaust. I was also thinking OEM parts like what we are doing here in this build so it cost effective. Would be a CNC expense project. Happy to help if you go after it.

[@MrGimmethreesteps]

Could someone just use s5 na rotors to save money instead of grooving out the rx8 rotors?

[@KyleMohanRacing]

Its not really tested. The side exhaust ports cause extra heat in side seals and rotor side. One of the reasons RX8 rotors have a scraper ring and a unique side seal. We keep RX8 rotors with RX8 side plates and rx7 rotors with rx7 motors. So basically I dont know. But we do know our combination worked

[@VictorMPR]

That middle exhaust port is so damn restrictive looking (but is it really?). Is there a way to get the GSL-SE middle iron to work in this combo? Would make the exhaust header a little less complicated, to boot.

[@KyleMohanRacing]

Ehhhh, why decrease exhaust potential just to make a mount easier on a custom build?

[@VictorMPR]

@@KyleMohanRacing Look at it this way: if we assumed that all rotaries benefit from having specifically the extra side exhaust ports, why isn’t everyone building these hybrids? Everything I have read leads me to believe the center siamese ports are tiny and problematic with a N/A engine. On a turbo engine there is pressure behind the ports and up to the turbine housing, negating the need for any real exhaust tuning (scavenging). I’m looking at building a N/A hybrid and was simply curious if the center GSL-SE iron would work, given that the rotor housings can be used in this combination.

I know someone running a Hybrid with 8:5 rotors, so far it seems running fine.

[@KyleMohanRacing]

Yea, but they are not designed for side exhaust port. I know of one on methanol that is a full experimental land speed car. Only logged about 5k total miles. If you are building a short term race motor that will come apart often probably no issues.

[@josezuma2116]

@@KyleMohanRacing Yes, Landspeed is a good example. I know a guy that has it for the street. So, in long term usage do you think the side seals will wear faster due to extra heat?

[@KyleMohanRacing]

@@josezuma2116 kinda outside of what we tested... but our data showed concerns about side seals both due to port intake shape wear and exhaust heat build-up. Also the wedge design on an RX8 side seal is meant to break down carbon which RX8s have way more carbon build-up. To really be quantified somebody would need to spend some money and do side-by-side testing.

Can you explain why these hybrid engines tend to fail so often and/or what the root causes of failure are? This topic is brought up so often and seldom actually done with a lot of hype and virtually nothing shown for results (more specifically in terms of long term reliable use). Until I see some legitimate long term problem free results (at least 100,000 miles of real world use) I still remain firm on my opinion of these hybrid engines. I encourage anyone to do this if they're willing to actually share their results, but that just never happens unfortunately.
