I have been kicking ideas around how to build the ultimate N/A high flow Rotary Engine. What parts and how much money would it take to build something that could flow enough air to make 350-400 horsepower to the ground?

Everybody that reads this thread will probably think I am insane but, that's ok I am willing to experiment with the Renesis 13B Motor. Now 350 is alot of power for a normally aspirated 13B Motor. But, it has been done before by Mazda and some of the All Motor Rotary RX7 competitors in the NHRA Sports Compact "All Motor" Class.

Here are my plans for the Renesis 8-Port Experiment Engine. Build a 13B Renesis D-Port or J-Bridge Semi P-Port. Using Front/Rear Renesis 6-Port cast iron housings with a Cosmo RE Center Intermediate Housing. The Rotor Housings will be 1978-85 13B but, I have a set of new GSL-SE Housings that will be used for the semi P-Port on this motor. RX8 Rotors have been modified to a standard 2mm Apex Seal groove so Apex Seals should not flex or do any of the weird stuff the rotors are known for doing. Everything will be custom made for this application so this will be expensive but, should make some good horsepower numbers. The Intake Manifold will be a 8-Port that will mount 2 62mm Terminator II Carbs built by Geers Engineering. The Exhaust Header will be a custom 4-Port eliminating the Renesis Intermediate housing built by Dyda Race Engineering. The Ignition system will be an Electromotive XDI system which is very simple and straight forward.

I'll post some pictures of the Carburetors, Ignition System and the Hood Scoop later this evening.

I've thought about something like his as well, your main problem is going to be holdng it together up too the 15,000+ rpm where its going to make peak power. Look into the guru 2 pieace E-shaft.

As much as I'd love to see something like this work, I really don't see it happening. There are too many problems with the design from a flow and port timing aspect.

sounds like it ought to be interesting if you get it done.

off-topic: you wouldn't happen to be associated with the Rotary Engineering of the days of old, would you?

Aren't there a few shops (I remember seeing one in Japan) that have made ~350rwhp with a 13B-REW PP high-comp N/A motor? The one in Japan made good power and did get driven on the street, despite its 2000rpm idle and 11000rpm redline.

I'm lucky enough to have seen some of the progress of Albert's project in person and I have to admit it is going to be one of the sickest N/A rotaries every attempted. The carbs themselves are a sight to behold!

Good Luck Brother!

okay ... i can understand the suspense factor and the need for build secrecy, but c'mon ... he can at least be merciful enough to tease us with pics of the carbies.

So you plan on running peri port exhaust with the Renesis side port exhaust on the front and rear plates? I have yet to stick a SE rotor housing up againsta REnesis plate, but wont your exhaust port timing be off between the 2? What about the regular apex seals and the side exhaust, Do they stay shallow enough to be supported?

I like where you are coming from with something new getting tried. I have wondered about maintaining just the side port exhaust, but having the semi pp intake. So keep the renesis plates and rotor housings, but just punch a hole in the housings for a peri port. Possibly minimizing overlap that a full peri port would have, and if you spent the time building an actuated tuned manifold so that the 5th and 6th ports are actuated but also the peri ports so that they only open in the upper revs, might have a real good powerful na.

the bridgeport has already been done

it would be a cool looking header....

or you could go the other way, old style irons and renny rotor housings, zero emissions =)

got any pics?

Here are some pictures of the Custom Intake setup. Custom Intake/Exhaust Flanges are being fabricated so I actually don't have those completed yet. As soon as I have them completed I'll take some pictures and post them to share.

Someone mentioned something about secrets. I would not have posted this information if I was being secretive about this project. I think input from other Forum members is a good thing. This is just a wild idea I had that I think would actually work well for my application.

Thanks

That is a very cool project. Good luck on the engine...

Wow. It's not exactly the best kept secret I'm not a rotary guy, but this project certainly got my attention.

Great idea, and from the work thus far, it should be pretty slick all said and done. I look forward to seeing some more pictures.

Carzy Driver

wow, looks nice!

dood, we need to drink some beer and hang out

All this design and money why not use Fuel Injection?

Jaime Enriquez

Because Albert is as old school as it gets. He knows carbs...period. If you worked on computers all day, would you want one in your car!

I do work on computers all day, and I'd have nothing else for my fueling needs.

That said, there's nothing wrong with a good carb.

I always have the idea of taking a 4 port renesis and adding PP ports to it intake and exhaust, you would have and economical engine and a 300 plus hp engine in one.

Kenku

... well. That's interesting. Not sure how it'll work, but interesting.

Here is a picture of my ignition system I plan on using for this project. I have read majority of the pros/cons of this ignition system and I chose this because I thought it was the best system on market today for a Normally Aspirated setup. This system was custom made by Bryan Smith from Rotorsports Racing in North Carolina http://www.rotorsportsracing.com

These ignition systems will be available as a bolt on kit for 1st Gen RX7's in a couple weeks.

Bryan thanks for everything and you do awesome work.

Thanks

Looks good, are you running a wasted spark on the second towers?

Also, watch those towers for rust. I run basically indentical coil packs, and have to make sure I keep dielectric grease on them so they don't rust under the plug boots.

SomeGuy_sg

Yummy , Good to see the project is coming along well

rotaryengineering

Digitalsolo, I plan on running the wasted spark on the second towers. Each coil will connect directly to a spark plug on the motor, but the remaining 4 towers will dead end into a spark plug box with 4 spark plugs. The first time I saw this setup was on a Modified Class car in the NHRA Xplod SportCompact Racing Series. The owner of the car was Dee Karagiannes Blue RX7. Man that car hauls ***!!!!!!!!!!!!
