Good point on the Renesis being a 13B. I believe Mazda refers to it alternatively as the 13B-MSP, for "multi side port"

[@versa_media]

You would be correct! Full government name is 13B-MSP Renesis

[@RiqueRacing]

@@TypeVertigo well, you're half- right. There are two versions of the renesis. It's the 6-port version that's called the 13B-MSP because it has multiple intake side ports on the front and rear irons ( 3 ports per rotor, hence making it a 6-port intake) rather than the standard 2 intake ports per rotor. The 4 port renesis makes about 169hp stock and revs to 7500rpm iirc (found in the automatic RX-8s) and the 13B-MSP makes 212-238hp and revs to 8600-9000, depending on the market and has a 6-speed manual.

[@RiqueRacing]

@@TypeVertigo so basically the 13B-MSP only refers to the 6-port engine that comes in the manual RX-8s.

Long tube headers have proven to offer no effect on a 0 overlap engine. Bridgeporting doesnt fix this, just lowers the combustion efficiency and intake resonance. Bridgeporting is a waste of time unless you live for the brap brap life.

Yep, that's how we did it. Sitting on a stool in the garage with a dremel. No templates, though. You did it by feel. Arguably the Engines were simpler, RX-2 and RX-4 motors. Easy to work on. There was NOTHING on them back then.

[@RiqueRacing]

Yeah you can, you just need a Bridgeport template and a Dremel​@@MapleMonarchy

[@gav240z]

I still would personally get the porting done by a pro. So many dodgy port jobs out there. The radius / turns in ports are more important than cutting the actual bridge. You also want a nice even job and no sharp edges for parts of the seals / rotor to catch on.

[@RiqueRacing]

@@gav240z true, and again, it's up to you. Some people would rather get it done cheaper and see a slight gain in power, while others are willing to spend the big bucks to get that port super smooth and still see a slightly bigger increase in power. Truth is, the value per dollar isn't there with porting the renesis.

[@brandondorman225]

If you're going to bridge port a motor so it can breathe better, it also needs to get that air out. 16:06 You might want to install a racing beat header.

[@ultimatejay]

and a cat delete pipe and good cat back exhaust.

[@mincvinyl]

Problem is the Rx8 has no issues getting air in. The side exhaust ports have a hard time getting air out efficiently. Which is why header and exhaust doesnt provide a massive benefit. Also why bridgeporting causes a power loss in the renesis because you ruin your intake resonance that was the sole design intent mazda worked so hard on.

[@ultimatejay]

@@mincvinyl that’s why you port the exhaust too. In naturally aspirated engines, every horsepower counts big time.

In highschool my friends dad had a new rx8 And my 1971 Plymouth valiant 318 2bbl (230crank hp) Could SMOKE that rx8

[@IStratz]

@@fastinradfordable It honestly would. They aren't fast cars by any means and basically anything that isn't an economy car will beat it. The main appeal to the RX8 is how cheap they are 2nd hand (because the engines die and nobody can afford or find somewhere to fix them at) and the driving experience is really entertaining. You get a 9250RPM redline and a very unique sounding (and in my opinion GOOD sounding) engine that just makes you smile when you drive it. There aren't too many high revving cars these days and especially for how cheap you can get an RX8 2nd hand. The high revving scream you get is just something that you don't get with a lot of cars.

[@TassieLorenzo]

@@fastinradfordable 318 CI versus the 13B that's realistically a 159 CI / 2.6L (when you account for the number of power cycles per rotation compared to a four-stroke). Granted 170 whp is only so-so for a 2.6L, but rotary engines aren't that efficient.

[@Xmvw2X]

RX8 vs S2000 battle, I have a little experience with this. I've raced a RX8, S2000, and FT86 back to back to back on an autocross course. I've raced a few S2000s over the years. I've even driven my current RX8 vs a newer GR86 in autocross back to back too. First, the RX8 is a very, VERY GT car stock. It's really softly sprung, amusingly so. It has good damping but it's sooooooft. And in turn, it doesn't handle sticky tires well. You'll be sitting on the outside strut bumpstops on every turn. The stock setup understeers...a lot. You can disconnect the front sway bar, and it'll get close to neutral with slight understeer on cold tires and a bit of oversteer on hot rear tires. But it's again way, way too soft. Unlike the S2000 and the FT86 or GR86, it's not set up for sport driving in stock form. So, you really do have to upgrade the suspension some. Stiffer springs and a change of dampers is needed in order to make use of stickier tires. However, once you do that, it's a much better handling car in high grip. The RX8 is a bit heavier. You feel it. But..this heft gains you chassis stiffness, a LOT of chassis stiffness. The RX8 was outstanding in this regard, on par with cars being built nearly 20 years later. The gain is a chassis that responds really well to suspension tuning and provides the driver with a lot more precisions. But, you do have to always carry that weight. The S2000 is a bit...uh...more floppy. But it's tuned well. It feels narrow around you, thin through the corners. It's much more firm stock and handles more sharply. The design feels purposeful, a surgical tool, a scalpel. It's a similar feeling you get in cars like a Viper. They're task oriented and feel that way. It just means they're compromised elsewhere, and the S2000 is a worse daily driver, but on the track it feels more at home. I can argue the FT86 and GR86 are more similar to the S2000 in this way, although both are more well rounded and less compromising. Both of those however are as sporty as the S2000 in a sport application. The RX8 is NOT sporty stock and needs the suspension work to get there. But once done, a RX8 feels really similar to a modern GR86 in handling and performance. Back to the S2000. The S2000 is more visceral. It's sharper, busier, noisier, more tactile. You feel a lot through the chassis. The engine buzzes. You get a good sense of the mechanicals, more so than any of the other cars. The steering...is dead, completely dead. You feel nothing through it. Out of all of them the steering is the worst. It's precise but completely lacking tactile feel. It's not unique to the S2000. A modern ND Miata is the same and really kills a lot of the vibe of the car. The RX8, FT86, and GR86 have more feel through the steering. People talk a lot about the S2000 shifter. I like the FT86/GR86 better. So the FT86/GR86 has the best steering feel, the best shifting feel. The S2000 has the best tactile feel and communication through the chassis. Braking is...pad dependent. All are fine, but pad choice plays a big roll in what you get in the end. The S2000 understeers more than I like stock. Both the FT86 and GR86 are more neutral in stock form. The RX8 understeers quite a bit in stock form. Modded, all can be neutral. Ultimate grip, this is subjective and my gut feeling driven them. I think the RX8 and the GR86 specifically have the highest ability on good tires. The FT86 is a hair down. The S2000 can be grippy, but I think it's peak isn't as high. It's speed I feel is more so a byproduct of lightness and not as much as maximizing tire grip. The RX8 and GR86 can get uncomfortably grippy where it almost hurts to corner. Ok, onto the engine. The wunderplant of the automotive world, the S2000 screaming engine! It's neat, and it was special for the time. Both the RX8 and the S2000 make the FT86 feel weak...because it is. The GR86 is a much lumpier engine with good grunt and ultimate power. The GR86 stands out as being the most torquey and very similar on power to the RX8 and the S2000. The RX8 and S2000 power delivery is VERY similar, similar torque, similar rpm range. The difference is the RX8 is MUCH smoother. It's silky compared to the S2000's harsh engine. Power wise, they're basically the same through all of the rev range. I'll give the edge to the RX8 for feeling like it has a little more lower and midrange shove (against AP1). The RX8 engine is also much lighter in rotating inertia and is a bit more rev happy. Back to back, I like the RX8 engine more, but in the modern landscape, it's the GR86 engine that stands out, a comparative muscle car with quite a bit more torque throughout. In terms of raw competency, I feel the modern GR86 is king. Stock it's good and can be used right away for light sport use. It's still not built for long track days, but none of these are. Modded, I feel it has the most total potential. Second place I feel is the RX8. The chassis is super good. The power plant is super good, despite the stigmas. Stock it's a cushy GT car, but it scales incredibly with light mods. Just a couple parts puts it right next to a stock GR86 in what it can do lapping around an autocross course. I probably should say the FT86 is third, but I won't. I think the power lets it down ultimately, and I think the S2000's power and lightness can beat it. The S2000 was fast, extremely fast. It still is, frankly, but it's mostly doing it on lightness. But I think it's the weakest performer from a chassis standpoint these days. I should point out one last problem with the RX8, it's gearing. It's a GT car first, and its gearing is looooong. You can go 65mph in 2nd gear. For a 10,000 rpm engine car with low torque, the gearing feels completely out of place once used in a sport environment. Frankly it feels wrong daily driving too. A great contract to this is the modern ND miata. 6th gear is 1:1 in that car, and you get the joy of actually rowing through the gears. That's fun. That's enjoyable. That's what should be in the RX8. I don't know if you can shove a ND transmission into a RX8. But you can buy different final drives. You can buy up to a 5.8:1 final, and this basically shoves 1-6 into the range of 1-4 and putting it pretty near what a ND Miata is set up like. For sport use, this seems like the better option. I actually have a 5.8:1 gear set I bought for mine. I'd love to tell you about it, but it's not in the car yet. They are only made by one fellow in Australia, and the they don't quite last very well, apparently, so before installing I want to cryo treat it to help it out a bit, and I just haven't done that yet. For me, this is the last key to the RX8 puzzle. This is a gearing advantage, area under the curve equation kind of thing, and a closer ratio gearbox is a better fit to a 10,000 rpm hp geared low torque engine. This is where the S2000, FT86, GR86, and even the ND Miata are all advantaged. It's just a goofy part of the RX8 being a GT car first. It doesn't need to be modified to be decent around a track or autocross course, but I think it can help a lot. However you might also argue less shifting is better. It's just a power vs shifting time game, and you pick your battles. I have a high power Subaru with the STi 6sp, and that's a close ratio shift happy setup. For racing, it's on the edge of being a little short on gearing. That's got the power to nearly outrun the first 3 gears in timing. The RX8 just feels way too long. It's just a low torque and a whole lot of rpm kind of problem. It felt like the RX8 was just the NC Miata transmission with nearly no thought on gearing for a 10k rpm engine and just plopped in as-is. It really feels this way. And newer RX8s got a slightly better final drive, not much, but slightly better. Mazda knew it too. They just didn't go very far. I like the RX8s. I keep buying them over other cars like the S2000. The S2000 simply hasn't wowed me or interested me like the RX8. The only other thing I've thrown cash at is an old Z4 because those inline 6s are cool, basically adult Miatas. There's lots of cars that are good in their own ways but I don't buy. FT86, no. S2000 no. Solstice GXP/Sky Redline I like but still no (these can actually be a super fun project car though, just don't like the packaging, rear suspension, and the whole convertible setup), GR86...maybe. I like the GR86 enough that I might, just might swap a RX8 for. It's quite good and modern and a big step up in a lot of small ways from the FT86. It just lacks character though which is a drag. Wall-o-text, I know, bad habit. Maybe some of it was useful.

[@Snoopi25]

There's quite a lot of things you can do in terms of supporting mods/bolt-ons to the RX8 to get more power out of it, including a few tunes; the Renesis under the right hands can make 230WHP easily with a tune, you just need a good exhaust (header is very important), and intake. Keep in mind, the ECU for the RX8 is VERY smart, it will adjust its tables on its own, best to clear the NVRAM if you're doing any kind of mods to it, especially now with the bridge port. I say it will make between 180WHP and 190WHP most likely in its current condition. Make sure your ignition system is up to par, need that strong spark to make the power. You can easily beat an S2k on tight tracks with the right suspension mods, brakes, and tire setup. He will walk you in a straight no matter what you do though. Oil catch can is a very common and very important mod on the RX8. Best of luck, looking forward to next episode. And please, for the love of rotaries, I hope you're running thicker oil than 5w20...

With a good tune and supporting bolt-ons to that bridgeport, you might tickle 200whp.

when installing the ppf that connects you transmission and differential you need to make sure that the transmission is at the correct height according to the service manual otherwise youre gonna have issues in the future with the transmission hitting the bar that goes across the bottom and more. this is from the service manual 1. Support the transmission using a transmission jack. 2. Install the power plant frame. 3. Temporarily tighten the nuts in the order shown in the figure. 4. Tighten nut 1 until the power plant frame is seated in the rear differential. 5. Install the heat insulator, exhaust manifold stay, exhaust pipe, silencer and front tunnel member. 6. Raise the front end of the power plant frame (transmission side) or the transmission with the transmission jack, and adjust dimension A to 55-57 mm {2.16-2.24 in} (lower surface of power plant frame-lower surface of the front tunnel member) as shown in the figure. Note • When raising power plant frame without a transmission jack, use bolts with a thread length of 55 mm {2.16 in} or more (M12 x 1.25). Tighten bolts from the underside of the front tunnel member as shown in the figure and raise power plant frame. • When using bolts, the undersurface of the power plant frame could be damaged. Wrap tape to the undersurface of the frame to prevent damage. 7. Tighten the nuts and bolts on the rear differential side in the order shown in the figure.

GREAT video Loved this engine build up - well done chaps.

[@kenngo3690]

Can't believe Ben rebuilt the rotary when he could get a free K-series from Mark's garage.

[@spannersautoandcomputerser1649]

Surprised you did not go with Angel Motorsports in. Virginia. RAD potential is still talented just further away. His channel will blow up now.

[@plav032]

They are crooks that's why. Why do you think Hert doesn't associate with John anymore?

[@OneEyeDollar6]

@@plav032 Jimmy Oakes posted a video today with Vargas building his engine.

[@Litevaar]

I'd trust Erich more personally. No ego and very transparent about everything. He's also an engineer by profession, so he understands the function and importance of tolerances and material properties a lot better than most builders. From what I've seen, even "trusted" rotary engine builders don't seem to know how to properly use a micrometer or indicator, or even feeler gauges sometimes. Side seal clearancing and checking flatness of irons drives me crazy in particular.

[@CraigBrosRacing]

😮 WOW YOU GUYS HAVE REALLY STEPPED UP THE EDITING 🤯.....DAMN GOOD JOB 👍

[@sooyster4033]

Watching a teardown and rebuild on this engine is so different! And what a fascinating mod

[@brandon_buildsDIY]

I would love to put a VQ37 in a RX8 would be a weapon of a track car. Good to see Ben keeping the 13b I love the way they sound.

[@KazeKanajima]

Been lovin the RX-8 content. Pls keep makin them.

[@techi9795]

Love watching some Lynchburg locals do some so awesome

[@speedistic0776]

I’m so happy the RX8 is finally getting some attention!

[@roscoes-wetsuit1]

I SAW THE S2000 UPLOAD EARLY, BRING IT BACK COWARDS

[@victorericsson518]

RAD Potential!! What is this collab. Am i dreaming??

[@carlwinslow4175]

Nice. I went around a few laps of Mid Ohio with a friend in his stock Shinka and was surprised at how well it handled, I always wondered what it would be like if it had more power.

[@jamesmchenry4708]

...I wonder if you can do a Bridge Port on a Bridgeport. Y'know, that thing that sits in the corner of the shop that looks like an oversized drill press. (I know it's technically a "knee mill" and Bridgeport is the brand name but still...) Also, Akimbo Impact Drivers. A fun way to have KZbin-Friendly Dakka.

[@philbert006]

Probably the template cuts. Way quicker and easier to just use a carbide burr rather than having to setup on a mill and find the appropriate tooling, all that. Turn a 30 minute job into a whole day, I would imagine.

[@SpencerSlaughter426]

I’ve watched RAD Potential for about the past three or four years. It’s such a cool surprise to see Erich here on my favorite KZbin channel!

[@gavinhogberg]

Another thing I recommend for horsepower is an exhaust if you don’t already have one. You already have a cold air intake, which is good, but both intake and exhaust are the best ways to make horsepower aside from bridgeporting since rotaries *need* to breathe. Racing Beat makes really good exhausts for rotary cars

[@brettharper4542]

It should make around the same power it would have made if you had just rebuilt it and fixed any issues. A good well built Renesis with free flowing exhaust will make 200-210whp on most dynos.

[@ryanng2083]

i literally test-drove both the s2000 and the RX-8 back in 2005, then I bought the s2000 instead of the RX-8. The S2000 was just superior in almost every possible way except for the sound of the high-revving rotary engine. straight-line performance, nimbleness, reliability, resale value, interior materials, shifter feel..etc

[@HotSneks]

This was such a cool video, learned a lot from the guys at RAD Potential :)

[@Lewuaptedama]

Rad potential in the house! Very skilled professional!

[@seanslocum3752]

I'm a big fan of Little Haunt by Tiger Gang! great choice.

[@jacquesc3166]

I'm 39, I've seen dozens of stock & modded RX8's blow their shiz up from the mid-2000's to mid-2010's when I was up near Toronto... so sexy, but most of us knew better and stayed away. Unbelievable chassis/balance, and one wreck of an engine.

[@TexasVexes]

Going to need exhaust and tune to take advantage of the bp. Thanks for keeping it rotary dude

[@alexgoalby9485]

I think you’re ready for a real parts washer and blast cabinet, they’d really help you out 👍🏻 Also I think you could splash out on some impact sockets 😎

[@that_escalated_quickly2720]

You guys make me feel good about my bad financial decisions

[@whozraptor5871]

I love seeing the rx-8 in your videos I cant wait to see more of it :)

[@TGBuild270]

It's definitely worth swapping out that header, plus a tune to lean it out a little. Should see 215whp

[@Threeuselesscars]

Is that a used jello-shot dispenser full of hi-temp grease at 12:47? Here I thought I was the only guy with one of those around! 😂😂

[@TheAus10Texas]

I would guess 207hp. I can’t wait to see this face off. Maybe after this the S10K with get turbocharged. Thanks for the great content fellas!

[@wma6019]

The Renesis is a Zero Overlap engine, which is why it doesn't Brap at idle, which means it doesn't gain anything from the change in port timing ,All of the NA Renesis power records are held by stock port cars for a reason.. The gains that will be seen are going to be a combination of just opening up the ports, and the refreshed engine.

[@jackwilder4538]

NOTHING BEATS RX-8 VIDEOS!!❤

[@pistons_n_pizza]

I loved this video! Love that you’re doing an RX8

[@randolphsmith7552]

I may never get to build my own car, but at least I get to watch other people do it. It’s all good, but I enjoy the content.

[@Syscrush]

If that car is on a stock ECU, it might have been reducing power in the chassis dyno due to the massive speed difference between the front and rear wheels. The stock ECU is tightly coupled with TC and DSC.

[@RattyRatson]

rad potential!!! hope they get big from your guys help

[@fivepointohmiller100]

Yes I've been waiting for rx8 content I've watched everything in KZbin already
