You sir. i must say what a privilege it is to be the first person to say WOW. This is exactly what i myself have been intending to do, will you run the side exhaust and side instake as well??
8 intake ports. 6 exhaust( or 5) 13b 13 port. this has 500bhp potential IMO.

Beautiful!

yomomspimp06 02-09-2016 08:09 AM

we need more details and pictures!!

Shortly to be assembled...

looks like.. exhuast flows to the peri first... taking the brunt of combustion heat.
looks like intake flows from the lower eyebrow first.. interesting.

start a kickstarter for a 3 pc shaft and center bearing mods for the intermediate place.. i've got 100 dollars i'll throw your way. just to see the reach a higher potenial..

yomomspimp06 02-10-2016 12:17 AM

who made those? this is going to be epic

yomomspimp06 02-10-2016 12:26 AM

well...I just figured out who you are

neit_jnf 02-10-2016 09:29 AM

it'll lose low end under 5k rpm but gain up top. interested in dyno once done. will it be NA or force fed?

yomomspimp06 02-10-2016 07:32 PM

if force induction...I would love to see this matted to a 6466 or s400 even.

maybe under 3k. you'd be surpised the torque one(13b pp) makes at even 4k rpm. though this is an animal of a completely different breed.

Stacked and bagged....

Looks good. I bought some old style 13b PP housings years ago to do something similar. Couldn't get a 2 piece shaft, so I shelved it.

Are you keeping the factory 6 port valving?

Brettus 02-12-2016 01:26 PM

Don't understand why you would bridgeport as well as PP ?.... Looks OTT to me ....

why do you need a 2 piece e shaft?

m_shake 02-12-2016 03:05 PM

Very cool stuff!!! Hopefully you'll post up pictures of the intake and exhaust manifold:)

you dont HAVE to have it, but it makes higher rpm power more obtainable. you can rev higher.

rotoryfreak 02-13-2016 06:55 AM

Will post updates as i move along on in... Will like to have some type of valve in the intake, But not sure yet. Depends on the customer..

Final resting place .. Miata ...

wastegate on the side ports, just throwing that out there.( variable exhaust valve timing anyone?)

never mind if the exhuast port opens earlier and closes later( which i think yours does.)

Johnny Kommavongsa 02-13-2016 02:51 PM

nice stuff

papadoo 02-14-2016 05:12 PM

very nice

jorx7 02-17-2016 05:15 PM

sweet!!!

Compared to a race engine I compared with, my renesis had more below 5-5.5kRPM, this was a simple PP both in and out, 320+Hp at around 8.5kRPM.

jorx7 02-18-2016 06:15 PM

looks like when its time to build my 8s motor chip will be building it!

Exactly...


200.mph,
Basically anything over 10k RPMs and the eshaft will start to flex. This increases the chance of the rotor impacting the housing. If you're running a peripheral port engine that doesn't come alive till say 9k, and is viable to flow air till 12~15k (example only), then you've essentially lost 3~6k on your RPM range.


Chip,
If you're going to use the factory intake at all including the SSV, know that in my application, the bridge on the secondary causes a surge up the secondaries and makes the SSV chatter like a bad valve. It also deposits some fuel / oil on it from the surge forcing me to clean it yearly because it sticks just like the factory oil blow back issues.

Just thought I'd share...
