This 2 Rotor peripheral port is running in the re-born Trans-Am series (GT1). It was in Road Atlanta last weekend and hopefully will be at Mosport the May 24 weekend when Trans-Am comes here. It weighs in at 1700Lbs! Power is about 330 horsepower and he is against cars with up to 800 horsepower, except they weigh in at 2700lbs.

 

wow, very exciting al. thanks for posting this for us. good luck to them.

 

Something else I want, but can't have

 

Can the RENESIS engine have a peripheral port?

 

the renesis is like the anti-peripheral port to begin with. In short, the normal exhaust port on any older 13b is a peripheral port and the the intake is a side port. so a peripheral port means that you have filled that side port and used peripheral port housings that have both intake and exhaust as peripheral ports. both intake and exhaust ports on a renesis are side ports (hence multi-side port on your engine cover). Therefore, you would just buy the real peripheral port rotor housings and its done (its not really that easy). what makes a renesis a renesis means it cant be a turned into a peripheral port without making it not a renesis anymore. You could use renesis internals (rotors, bearings, eccentric shaft as far as i've read they will all work with slight differences that may or may not need to be modified to work correctly) in a peripheral port motor, but its not a renesis still.

note that a peripheral port isnt just a bolt on mod.

 

major engine rebuild, and engine bay redesign to get a peripheral port in there!

^Lol, I was just going to look up that video.

I've done some experimenting with regular housings from older 13B's. I have a nice old Bridgeport Milling machine now so I've been cutting PP holes in junk housings to see how they turn out. So far so good! I just need to put a set into an engine soon lol.

I have a pair of PP housings I had a buddy of mine make for my drag race car.
Looking forward to getting it running!

 

I will see that in action hopefully!

 

Much easier way to do a P.Port is buy them from Racing Beat, they are proven and brand new. The RX8 e-shaft and rotors dont make as much power as the 89-91 n/a rotors and the best e-shaft is out of the 1985 GSL-SE. For ultimate power you can get the Racing Beat ultra-light weight rotors but that adds about $3500.00 cdn to your engine build.

 

Whipping out a credit card to get PP housings is pretty easy...but no where near as fun as building your own

The PP housings I have are proven in Puerto Rico as well. Same housings that Nitrous Drag cars run low 8sec ET's with.

 

You guys still business? Just wondering because no replies to either phone messages and PM's...

 

Yeah we're still rebuilding engines and working on RX-8's/RX-7's.

I just looked back in my pm's and I haven't receiced any messages from you in a long while.
Our phones, internet and emails have all been down for a month so getting ahold of us would have been hard.
Everything is back up and working now though!

 

What would be the advantage to transforming them to peripheral port rather than a straight engine swap? Also what modifications do you make to the irons, or do you swap them out?

 

When buiding a p.port you fill in the stock openings in the irons. We use a special process and a ceramic made by Devcon. If you go to my website you can see the stock ports filled in, the section is p.port engine building.
