CNC Porting by Rotaryengine.com 

This is a thing of beauty. A while back was working as head mech/crew chief for 2 SCCA GT2/GT3 Mazdas. Became friends with 3 of the best West coast rotary engine builders including Daryl Drummond, the contract builder for the 1 gen Formula Mazda/Star Mazda cars. Seeing this reminds me of the many hours of meticulous effort that goes into building a strong, reliable rotary engine. A momentary slip of the grinder can ruin a port or housing but your CNC work alleviates that. I like the final blending and manifold matching is left to the owner saving time and possible mistakes of the critical details. Nice work. Would be interesting to see the M code for this.

This process just changed the porting game big time. You guys are badass.

love how that bridgeport and notch lined up perfectly

Great services you guys are offering. I'll have to give you a call before I rebuild.

Great work and explanation. Thank you.

You just got yourself a new customer

AWESOME JOB GUYS ABSOLUTELY BEATIFUL👍

Damn....dat notch.......its too satisfying....

Awesome! Thanks for sharing.

Daamn guys it is obvious that doing this type of job manually is never going to be soooouu perfect than doing it with machines and its program that it programmed in it..congrats for the 110% perfect job on these housings and ports on the irons,there isnt nothing that compares to these masterpieces guy...nothing...👍👍👍👍someday iIll do this job on my fc3s turbo II its worth it😀

How does this BP effect apex and corner seal longevity? Doubtful I would ever go this extreme on my 7, but just curious. Great vid, as always!! 👍🏻

Any chance of doing a vid on j porting , it’s a popular port here in Australia, I have a 84 rx7 12a j port

I'm absolutely loving the passion and precision you guys are showing. Is this the type of service that is suitable for hobbyists too? Or mainly for racing applications where cost is less of a requirement? I'm from Europe, and I'd like to know if you guys often handle parts from EU customers, because of the shipping and all... Keep it up :)

Beautiful job

Do you have a video that explains the differences of bridgeporting vs p porting etc?

Do you guys do peripheral porting as well?

I have an rx8 which come to the end of its first life.. looking for someone of good quality and character to rebuild... any suggestions..

Awsome!

I hope you chamfered the edges of those ports so they don't cut the corner seals.

Whats the difference between bridgeport, street port, and peripheral port?

GR8 job!

Beautiful work, what kind of power and torque numbers can you expect on a 13B utilizing the CNC street port ( no other hand work, just the machine work ) NA or turbo?

When you do the bridge port in conjunction with the housing being cut as well. You would need to use 1 piece seals?

Nice!!

I'm new on this I need done everything

looks awesome

Have you guys done or though about doing 3rd gen engines with the RX-8 front plate so you can have all the OEM functionalities of the car while having a more reliable and powerful engine?

Do you have a website?

Hey, I'm curious if you can tell me how much of a gain is to be expected from an extended port 6port rx8, running a intake and header back exhaust, & Cobb accessPORT

Y esas cosas todas cuadras funciónan?

about how much would shipping irons out for porting if i live in the midwest usa

Why did you make the bridge so small? Is that a half bridge? Or was it for demonstration purposes only?

Please tell me you do this for overseas customers? If not I hope there are rotary specialists offering this in the UK. Trying to build a naturally aspirated 13B MSP engine with power that most people say is unattainable.

How much would it cost roughly for an RX-8 bridgeport?

Good afternoon! Do you make that service with bridge for 6 port hp Rx8? When yes, do you no the cost with your Fedex shipping from and to Poland

just wow

The amount of money on that shelf

What are the gains/benefits of porting a rx8?

Price for that

Did apex seals from one piece?

How much porting can be done by hand? Building a Lemons 24 RX8 so budget is none existent but I can do unlimited labor. Looking for options since I have to tear down the motor anyways. Gotta try to make it last as we are running laps for charity donations to Saint Jude’s Children’s hospital.

Where are you guys located

The furture is here 🤔👌

The outside of the bridge and the coolent seal is to close, doomsday isn't far. Extended port is the best way to go, like they say, if the bridge is near, so is disaster.

Email?

5 axis should not need any hand work.
