Engine is running in a drift FD in the UK... thought a 3rotor with side exhaust ports wasn't possible! :lol:

The vechicle that's it all in.

say what?!? looks nice, what are some of the output numbers and more information please

pdxhak 03-20-2008 08:32 AM

It was just a matter of time before someone made a 20b Renesis. Is it running?

mike1324a 03-20-2008 08:41 AM

I like it. Any idea on power or if its ported?

lennon 03-20-2008 08:58 AM

This is what i'm waiting for......

rotarygod 03-20-2008 09:06 AM

Cool looking. It's based on the lower power 4 port engine. I'm not so concerned over whether it actually runs as I am with how much power each rotor makes in relation to each other. I just can't believe that the middle rotor breathes as well as the others due to both of it's exhaust ports being siamesed. You really do need to see those up close to fully appreciate how terrible flow through them is.

ITBs on a 3-rotor Renesis... yummy. :yumyum:

That's what I found most interesting.

Too bad there is not any information on 20b build.

Spinning Sushi 03-20-2008 11:36 AM

Too bad it's not based off of the 6 port renesis like RR said. I would've been nice to have a total of 9 ports...

More intake ports don't help solve the problems with the exhaust port.

If it's a 20b rene, why does it have 4 exhaust tubes? Isn't it a 2.6 that is two rene's put together??? Even though it just has 3 intake tubes???

edit: NM, I just looked closely again and saw the rotor housings.... <---nub

It's a 20B, not a 26B.

The Renesis has exhaust ports on each of the side/end plates. 3 rotors = 4 plates, 4 plates = 4 EX tubes, or primaries. You can clearly see the exhaust is not on the periphery, as pre-rennie. A 13B rennie has 3 exhaust "tubes".

Cheers,
Hymee.

Nemesis8 03-21-2008 04:03 PM

I wonder if they figured out the MOP for that setup...

rotorocks 03-21-2008 04:42 PM

Why isn't it boosted? :lol2:
Looks nice though, but like RG says, the mid rotor might have difficulties breathing, those shared ports are really tight.

Renesis_8 03-21-2008 05:09 PM

nice to see it done. I predict it could make about 350hp. I don't think the middle rotor of this setup could handle a 6-port version, the exhaust side would be really restricted.

Yup 26Bs have 4 rotors :)

A quote from the creator!

'Since I have actually built the engine and tuned it i can say that it is very good and I have not driven an N/A engine like it.
This is what the RX8 should have in it.
It has lots of low down torque ,but still wants more and more revs.
Zero overlap of the inlet and exhaust ports helps with exhaust evacuation.
The car has not been on a dyno yet,but I can say that it pulls harder than a modified FD RX7 that is still on stock twin turbo's running around 330hp.
Regards'
Carl

crispeed,

If you have not already done so, please invite the builder to stop by to discuss his build :)

if a four port 2 rotor only makes 190hp then 350hp seems a bit optomistic for a 3 rotor 4 port .....

He said HP not WHP, so I don't think 350-crank is too far off.


I want a video of this, I want to know how it sounds :)
