I don´t own any car. I just love to see this man´s workmanship.

bore anybody? Does this guy not realize how many times we come back to watch his artwork? Artwork so amazing it's borderline pron?

This is so freaking cool. I love seeing all these different parts from the RX8 and RX7 being put into one wankle. N/A is the way.

It's a pleasure listening to this man's low key patient understanding and appreciation of this wonderful engine design during assembly. I love the rotaries like I loved racing crazy fast 2 stroke street bikes for years. No four stroke engine will ever hold a candle to a rotary,or for that matter a 2 stroke motorcycle engine. Simple,durable,and huge horsepower per cubic inch. Give me a rotary car,and a Kawasaki H-2 triple,and I'm a happy man.

I have running '85 12A and 84' 13B GSLSE engines. The plan is to combine the two for a ported NA motor. But I'm not sure if I want a bridge in a 1200 lbs street car that will only see occasional track time.

Did I miss something? How are you keeping the corner piece of the factory apex seal from falling into the port on full bridge? Both sides of the rotor housing has the notches so there's no support for the side piece. I must be missing something? These seals don't look like 1 peice seals, that's why I'm asking. Edit: Nevermind! Seems the side plates and apex seal itself keeps the side piece in check over that gap.

@rx7specialties203

Once again...Its not about support..in fact..the whole concept behind the bridge is to provide the necessary support. The concern is actually the tip of the end piece catching on the notch. Ideally its best to use 1 pc ceramics yes....but I have used 2 pc seals many times. If you think about it, the 45 deg cut along with the side housing prevents the end piece from moving up so very unlikely to catch.

I just never seen someone build a FULL bridge with factory apex seals. But your right about the angle. That's why I edited my OG post! 😉

Thanks for the video, very useful information here. One thing I'm wondering about: the housings have been notched on both sides, how does this work with oem multi-piece seals? Will the triangle piece have enough support? I'm doing the exact same build and am still trying to figure out to what extend and length the notch can be made on both sides Thanks!!

Couple questions. Is this streetable at idle with a holley sniper injection? What were the final numbers on torque,hp, redline. In 2022 what price range is this in

Have to say in this case your wrong with those size ports for an n/a engine, over here in nz others have built these big massive ports and they don’t perform. Btw I’ve been building 25 years, turbo yep go massive, the limited very few have discovered here that 3B rx3 ports are as big as you need to go for a n/a engine, full length bridges, extremely torquey without losing top end power. Question what’s does n/a rely on A. Gas speed. Big ports slow the gas upon entering the housing resulting in performance loss. Fast gas speed more torque, still the same top end. This only applies for n/a. Bigger is not better unless you are going turbo.

Hey, my friend, I learn a lot from watching your videos. I would like to ask a question. A guy that has a rotary engine website. He explained to me that synthetic 2 cycle oils leave significant deposits in the engine; and that Marine 2 cycle oils are for a different type of 2 stroke engine than a rotary engine. I found that Briggs & Stratton is a low ash cleaner-burning 2 cycle oil. Does any of this make sense to you guys? Thanks!!

Yes they could have been an option but we have learned that the extra .3 in compression does not yield noticeable gains. Also, when running apex seals over a peripheral exhaust port, you really need to use a tall RX7 apex seal, in which case the RX8 rotors need to be EDM'd to full depth slots....its pricey....plus the narrower side seals from the 9.7 rotors seal better

​@@rx7specialties203 It cant be done by any of the other methods you offer, like milling?

On the topic of early irons, can you run the early center iron on a gslse engine to make the port larger since the se iron does not have much material before you hit the water jacket? I’m currently running dcoe style throttle bodies so there is no need to use the stock injectors that would be in the se center iron. Car makes 197whp on a popular Australian dyno. And what would be the gains if I were to send it to you guys for either a maximum street port or half bridge?

@rx7specialties203

4 жыл бұрын

Yes you can. They flow much better. Its just the early irons are carb irons and dont have injector ports so you need to run ITB's with fuel rails built in thus ditching the stock SE EFI

Why not use the RX-8 Rotors? I thought they had higher compression.

@rx7specialties203

5 жыл бұрын

They dont make anymore power and they're are extra costs involved as they need to be EDM'd to full depth 2mm to accommodate the taller seals necessary for rigidity to pass over the exhaust port along with the ful depth custom corner seals. Unnecessary costs to gain virtually nothing.

Why are turbo bridgeports smaller than aspirated bridgeports? I don't get it?

@MJTAUTOMOTIVE

5 жыл бұрын

Port overlap, the longer ports on a n/a build are for longer duration of the intake charge. Basically the same as putting a high duration high lift camshaft in a piston engine. When you turbo charge a piston engine you put in a boost (or turbo) camshaft not one with heaps of overlap. It works the same in a rotary engine. Hope that makes sense. Cheers Mark.

@MJTAUTOMOTIVE

5 жыл бұрын

@@BoogalooShrymp . Because the port in the housing is positioned around the same place in degrees as a good turbo port in the side housing (iron). On a semi peripheral port the port size is very small compared to size on a n/a peripheral port engine. When the peripheral port itself is smaller it is also not as large in degrees as a big n/a port. They use the semi peripheral port to increase the amount of intake charge in volume without changing the overlap "ie port timing ". Cheers Mark.

@rx7specialties203

4 жыл бұрын

Good words guys but also during overlap boost pressure can escape the intake charge and is forced into the exhaust. EGT;s can raise very high when fresh air is introduced into the burning exhaust gasses. A short smaller bridge at the top of the port only can reduce the amount of fresh air feeding the exhaust stroke
