This BRIDGEPORT RX8 Engine Might BLOW UP Instantly - Hybrid Renesis 13b

[@shawnsmith4404]

Dude I bought a rx8 4 months ago that flooded day 2 of having it. Your videos and a few others are the only reason I didn't sell it right after. Love and hate relationship right now but more love then hate and can't wait to have it at 100%

[@joeyvega8991]

I heard the primary cause of flooding is either shutting off the engine cold or at a high rmp, shut off the car after it's warm and the idle sits at around 900 rpm. I love my Rx8 rn but yah I'd admit it's a little pain especially if you daily and drive it really hard but it's worth it. Can't wait til he gets the hybrid done I need a reliable source before I swap mine 😂

[@no_tripple]

From the moment I discovered your channel I was mesmerized by your own unique approach, expertise, and way of handling the Dorito engines. I truly appreciate and love the enthusiasm and your will to show us even the “secrets” and all the uniques of these engines. Sir, I applaud you and you’ve won me as a fan. I aspire to have your confidence and experience with the rotaries. I want to see your video viewership levels of at least Rob Dahm’s, Keep them videos coming, cause we like what we see. Keep it RAD

[@NotNicot]

This is exactly how i feel, this channel deserves so much more for the great content it outputs

[@InsideOfMyOwnMind]

Rob Dahm is also a very knowledgeable participant with the viewer's best interests equally in mind but he uses more eye candy and for better or worse that's what sells. Personally if I was actually looking to build I would come here first.

I clearanced all my side seals by hand, with a piece of 1500 wet/dry paper, and 6 thou feeler gauges down the backs of the side seals, as mentioned in the vid. Also put all new seals and resurfaced housings/irons in. Resulted in 110-115psi across the whole motor.

[@MrCool00236]

Looking forward to the results. I'm going to be building 2 RX8 engines. One of them will be hybrid, but I'm going to machine the rotors for RX7 apex seals. Playing with the idea of just cleaning up the stock intakes and using a semi pp approach to better match the flow of the exhaust without needing to bridgeport. In Japan right now but I'll be back home in August to start machining and hopefully starting them in September.

[@TheRealMax77]

excited for this build!

[@rotaryperfection]

3:30. Actually, there will be more heat on that apex seal due to exhaust flow in that area. That's why the seal eventually warped with Mazda Trix over time. Now, for your short term experiment, you may be good for a little while.

[@williamporter7495]

The heat on exhaust ports on renesis is due to 90° exhaust path. Put traditional along side renesis, more flow, less heat. Simple

[@rotaryperfection]

@williamporter7495 You're missing the point. When you add PP exhaust to the shorter Renesis apex seal, you increase the heat on the apex seal itself, with the seal now being exposed to the open exhaust port. Without the PP exhaust, it keeps that shorter apex seal cooler. Now you will releave some of the heat on the side seals, but that heat now goes to the apex seal due to PP exhaust exit. During development, the new 8C range extender in the MX-30, Mazda had a problem with the normal Renesis sized 2mm apex seals warping due to the higher heat from the increased compression ratio. Mazda had to engineer thicker 2.5mm seals to fix the problem. Keep in mind that the 8C doesn't even have PP exhaust.

[@lexeg1]

Don't care what people say. I just want to see this thing done

[@3kzack]

Keep going, we definitely need hard proof on these motors whether they work or don’t work

[@boredgaminglowammo9335]

You had me at, Bridgeport

[@InsideOfMyOwnMind]

The side seal jig in the drill press is just mind blowing. It looks like the secret is you have to use a rotar tip of the type your building and the abrasive drum has to fit the corner pocket as closely as is practical to get the right end profile.

[@phillipliems7963]

Don't listen to the H8rs!! I'm so excited for this build and it's not like this is your first stack 😂 I followed Kyle Mohan's hybrid build but he gave 0 build details and lookes like it cost 100 rx8 seats! Best channel on youtube. Keeping it RAD over here!

[@rucarnuts13]

Always been curious about a hybrid Renesis. I know nothing of the Renesis, I’m a 12A guy, but I’d long been told those engines big achilles heel were the side-exit exhaust ports and the poor OMP oiling in the early engines. Looking forward to seeing how this engine holds up.

[@tlovsoe4211]

I think a divider would be better than a helmholtz resonator on the siamese port

[@JRosariohomestead]

You’ve done your research, and seem to have a plan before you do things like this. Your videos are awesome!! I am waiting on to see if there are power gains to hybridize the Reny.

[@BeaverLakeMotorsports]

For renesis side seal clearancing I have 2 feeler gauges cut down to allow them to be horizontal and shim the hole outer side of the seal so it doesn't bow out, I find that it gives more accurate & repeatable results.

[@josezuma2116]

I know 2 renesis running with RX7 rotors. 1 of them was the landspeed (600whp +). Sidesides are fine as long as you don't leave any sharp edge in the intake ports.

[@lugnut93]

Keep it going! We need somebody to push this through.

[@thorsullivan5767]

Awesome content. I would love to see you Continue improving on this after the fact to dial in a standard of a “hybrid Renesis”. Yk if it fails, determine why, and make improvements for a tried and true engine. This is Def a huge bonus for the rx8 community.

[@jaredrule1431]

Have you thought about ditching the Renesis centre iron and swapping it out for an FD one? With a hybrid build, this would be a good way to ditch the terrible Siamese exhaust port, driving more exhaust flow out the peripheral ports.

[@mattmartinez3298]

I've been gathering parts to build a hybrid. I'm planning on using a 12a center iron to eliminate the center exhaust port.

Ask Brettus on the forum. He's the rx8 tuning guru here in NZ. He's tuned a few hybrids now. Dyno's weren't impressive ... they need a turbo.

[@bobbyshaftoe]

Renesis Hybrid is was brings me here. I wanna see a non-bridge hybrid with all stock plumbing, one with proper headers, one with proper headers and proper intake, ...turbo.. M90 supercharger... electric supercharger... etc.. with dyno and low end torque numbers .... 😛

[@tlovsoe4211]

I don't know about an electric compressor.but testing especially if you want to control all you variables (same engine with same cc rotors same dyno...) it would be very costly

I did a turbo hybrid renesis with the rotor rx7 the engine heats less with the additional scarf say it doesn't work it's lie I will show you a video on it that it works aimed at 700 hp( with RX7 Houssings)

[@Darkipod]

You should probably reach out to Kyle Mohan Racing and ask him this. He claims to know all about the hybrid builds and was allegedly the engine builder at the time.

[@jimbowcracklehead8071]

He also tries to sell product foe mazdatrix, so not everything he says is entirely make or break. However he does have great pointers

[@thor3901]

My question with the hybrid builds is is it worth it? The problem with the Renesis seems to be that the performance ceiling is low at about 400-450hp through forced induction which then severely reduces the reliability. If a hybrid motor can increase the performance and reliability ceiling then it would be worthwhile but if all a hybrid motor does is increase complexity without any gains what's the point? Assuming it can be done, why bother? That's the question that needs to be answered I think.

[@Freeride600]

I'm really curious to see how this works out. Couple years back i was super curious about pushing the NA renesis past stock form but found very little info.

[@jvest6515]

Haven't watched the whole video but on my renehybrid I machined my rotors tu fit rx7 seals... But I was talking to someone in a FB page for the Renesis hybrid he was running it with rx8 super seals I believe he said. And it was running good.

[@jvest6515]

Maybe it wasn't super seals it was one of those seals tho

[@jvest6515]

E shaft timing" .... 🤣🤣🤣 BP on a standard renesis IS completely pointless, but in this application it will be interesting to see how it works....or doesn't. Great video, thanks for showing the side seal clearance process in detail, it's crucial for renesis compression/ power. Can't wait for the next one!

[@andrewable2634]

My logic says that people never documented results because it was dissapointing af in an N/A configuration. I figure a turbo hybrid configuration would be super trick cause of all that extra exhaust flow.

Hi Did you uprate the oil pressure regulator. People add shims to the front regulator ,this seems like a bad idea to me as these like a safety valve for the oil coolers. Does any body know what the front regulator is set too or what they are increasing it too with the shims. .

[@57rotary]

Could you bridge port the exhaust port please in a way that does something. Never been done so it would be experimental and you would get a high audience from your videos

[@FreeFormSportss]

Would it be worth picking up a 2005 Automatic Shinka special edition? It’s got 90k on the body but 16k on the engine. I plan to put a 20b in it when I get enough money in a year or two. If not, how possible is it to swap a manual in the auto?

[@Ayane13b]

Autos have different engines than the manuals. 4 port vs 6 port. If you want a 20b, just wait until you have the funds to get the car and do the build. Otherwise you'll be stuck with an auto RX-8 lol. Or just get a manual and enjoy it as is whether or not you swap it

[@swampyfox8688]

It’s a massive pain. Hold out for a manual.

correct me if i am wrong but does it not require you to relocate the steering rack if you fit a 20b.

@@tlovsoe4211 not too sure, haven’t done the most research into it yet as it’s just an idea for now

@@Ayane13b yeah I figured I can’t tell but after looking it up the only 6 port autos were the 2006 and above so unfortunately the one I saw is a 4 port. Sadly in my area there aren’t many shinka specials left that are manual I’ve only seen 2 in the last year and a half

[@Yorchoice1]

It works with RX-8 apex Seals I have the proof I can send you a video that it works

[@rotaryperfection]

Yea but for how many miles and were you racing? Over the long term, you're still exposing the thinner apex seal to additional heat of the peripheral exhaust port. More heat on the thinner seal, it will eventually warp. This is what Mazda Trix experienced.

[@Yorchoice1]

We still testing in the Dino so far. We have not blown it up.

[@nobodyspecial5026]

There are two factors 1. The shallower beam on the Renesis apex seal warps much easier. 2. The shallower apex slot in the Renesis rotor wallows out quicker. It was a mistake that Mazda and RX8 owners paid for greatly. A Renesis engine will never sustain 120+ psig compression long term with them. Reusing Renesis rotors with any notable mileage on them is a guarantee to never achieving optimum compression. But in the land of youboob, 30 seconds of attention harlotry = long term success. .

Goopy seals ma man they don't shatter?

[@Liquorpuss]

REsurface those housings. Pour oil on them and watch it bead up. pour oil on them after it has been resurfaced, not milled, and the oil will have retention. It's like not honing your cylinders or reusing brake rotors and not resurfacing them. It is even worse because of all the seals in the rotary. I'm not sure why that is a lost art on the rotary community.

[@kevinobrien3063]

That a hard one, you would have to try this on a new from factory plate to see how the oil is retained. There is a lot more oil being injected in a rotor engine than a piston one so does it matter. How fast does it take to get to the polished look after lapping . I think the engine runs most of it life on the polish look after break in. If you lap the plates you loose the nitriding so is why the oil in retained.

[@Liquorpuss]

@@kevinobrien3063 The nitride coating is .003-.005 in thickness. Resurfacing takes off .001 or less. Just a lap not a mill. Allows for proper seal break in as well as oil retention which matter on the overall surface wear regardless how much oil is injected. AT what point do the plates become polished in appearance is a good question.

[@AzureTF]

Nobody who knows what they are talking about are saying that the engine won't work. It's simply just not going to magically give you any more horsepower than a good stock renesis engine, and then you lose all driveability because the exhaust port adds a ton of overlap, which the renesis is not designed for. There are NA hybrid builds with dyno graphs out there and they don't get any more power than a fresh stock engine. If you go turbo it will still be just simply worse than a REW motor swap for the same reasons above. Hybrids have no low end torque and you don't get any usable power until you get past like 5500 rpm. I can't wait for you to get to the same conclusion that everyone else does when the engine is running (because it will run, just not how you think). Everytime someone does a hybrid they post a video it running. Then it either disappears from the internet, or they switch to an REW, and there is a good reason for that.
