13b "Renesis" Project must see

13b "renesis" street ported & Semi peripheral ported 2011 engine .

balanced , scalloped ,clearanced

Adaptronic Ecu

will be posting more soon we are about to test this machine

What's the point of grinding the housing if it's not bridgeported(bottom right pic)? Btw, wrong section.

Rotary Werks

good observation , housing was already like that , wont make a difference

where is the right place to post this ?

dznutzuk

I'm not 100% sure but I'd say Major Horsepower Upgrade section.

Are you serious?

Great way to deter customers you win the internet.

dznutzuk

Looks like a very old gl housing with water seals and 1 oil injector per housing.

Much easier to use that housing versus a later 13b, which would require you to make machined cuts into the housing or rotor.

So that part makes sense....

This is going to be interesting.
IMHO I feel that the intake port pictured (Bottom right pic) is going to cause you some grief. I do not think you left enough material on the outer edge. But that's just me.

But does it make anymore power than a stock Renny?

Sounds cool.

since the PPPs would have to go through the APV actuator arm I'm assuming you must have pulled the barrels and have it running them open all the time

but you went to all the trouble of balanced, scalloped, clearanced blah blah blah and couldn't swing for a decent or new housing?

I suppose it's not clear what the exact combination of parts is, it seems like just a Renesis with PPPs, but some seem to think you used GL exhaust PP housings too

Surprised we finally agree on something...

From further inspection I came up with the following.

Its a 12A housing with a hacked up LIM. It looks like they kept the APV's in place you just cant see them in the picture because thats the intermediate housing.

It has one oil injector which I don't think they are even using due to its location ( not even sure how you would meter a single injector...). So 100% premix :/.

Now, what we can barely see the top of is the peripheral exhaust port, so this engine has...

Intake:
6 large primary ports (4on the stock renny, 2 with the addition of the housing)
2 APV ports

Exhaust:
4 Stock renny side ports
2 Peripheral ports with the addition of the housing.
.....

I am sure this thing is making power, should be close to 230 whp NA.

Bottom line the concept is great the execution is very poor.

Stray

Very innovative. Even if the execution is poor, it's cool to see people experimenting & I'm sure if it's a sound idea, someone will come along and do a really nice one. I'm interested to see a dyno pull. Not so much for the overall output so much as what the powerband will look like.

100% premix .

will give details later on ...




i have many newer housings , i just wanted the 85s is my prefered option

If you can move past acting like an 8 year old I'd love a better response.

I wrote up what I thought I saw from the detailed pictures you put up. Maybe you can provide more information? Also if you do not consider that LIM as not hacked up you must do the fabrication for turblown on the side.

If not I am just going to assume I was correct.

Rotary Werks

Hey my bad , is different from what you said ... i will show later

im just sharing this with you guys , i really don't want to get in a argument

dznutzuk

Sounds good though.

shadycrew31

iTrader: (6)

I'm not looking for an argument I am interested in what you are doing.

I am more interested in the exhaust manifold than anything else.

Cool build, waiting for results.

Why not run the semi-pp past ssv.

Are you keeping VDI on? Do you expect any negative impacts from the semi pp's?

Rotary Werks

im expected negative impact on very low rpms . but the thing here is that im testing it on a 1988 rx7 5 speed with 390 gears so that wont help to feel close to a rx8 ...

this will go in a 6 speed 11 rx8 with 512 gears .. all i will say for now is that if you set the rpm limiter to 11k the engine will make power all the way up. im still tweaking the only valves i got to get the most bottom i can . will post more soon !!

thanks

The ground out rotor housing will make it worse despite your claim that it won't matter

Rotary Werks

right ... I wish you can be here see it & drive it so you can re-think what you just said
