Team- Warping was practically nonexistent. Either way, it doesn't matter because once it's milled to spec and coated/lapped, it'll be flat as can be. I doubt heat will be an issue, especially considering the filled area will no longer be a hot spot. But, as you said, time will tell.

fisher are you closing your side ports in favor of peri ? i must have missed that... i plan to do the same for my turbo build, if a white blown rx8 ever finds its way to me. until then its N/a refinement.

nvm, i went back to where you are closing the mid... like i was gonna do :P

I've closed ALL of the side exhaust ports. Peripheral only on this build.

I'll bet anyone $5 that the material surrounding the welded shut side ports fails within 15 hours runtime.

Any takers?

You must be a metallurgist. Or maybe not, because a real metallurgist would be able to wager more than $5.

Well you aren't a metallurgist and apparently you wagered a lot more than that ...

Well, IF it fails (and that's a big ******* IF) you and your fellow nay Sayers shall have the simple satisfaction of being able to smugly proclaim "I told you so." If it works, I'll have a setup that I'll enjoy. Last time I checked, nobody here is funding my build, so the negative opinions (also NOT backed by experience or tangible evidence) are just that- opinions. I'm not looking for praise for trying something different, but what I'm doing is what hot ridding and grassroots motorsports are all about- something this community seems completely ignorant to. The mentality here seems to be"Oh, it isn't an off the shelf bolt on kit? That will never work."

Then why not do it first and publicize your success after? The exposure of your own opinion to everyone else's is entirely your own doing.

It also has nothing to do whether it's an off the shelf kit or not, which is an entirely silly thing to say.

That's a Ric Shaw Custom Port renesis engine, really, it's hard to call it a renesis still, as it's basically had Peripheral exhaust ports cut into the housings, and had the side ports (for the exhaust) blocked off. It also has a full length custom (2 pipes to diff) extractors and exhaust.

It sounds mad, however the sound is about the only thing it has going for it, it dyno'd at 133kw (~7500RPM) and power dropped quickly after that ��

Rick's dyno usually reads lower than most. On his dyno a standard car does around 100kw atw. So this is an improvement over stock.

If it's that low ...... He needs a decent dyno

Regardless, it is a substantial gain over stock. If you add FI to the equation then the gains will be amplified.

Ric Shaw has been working on the Renesis for a number of years now and has been experimenting with various upgrade options. He is a also a professional race driver and has a number of race cars including RX8"s.

We should all encourage experimentation across the board as it provides insight into future development of our platform.

First, if there are things coming up you don't feel should be discussed then the last thing to do is challenge and ensure more discussion on them. .

Second, my opinion means no more than either yours or his or anyone else's. This is a public forum and opinions vary. There's no need for anyone to get upset over anything, let alone resort to childish name calling. You seem to think the world should revolve around your own opinion and nobody else has the right to a different one.

Finally, nobody is trying to tear anyone down, but there are realities and limitations that can't be ignored. Like installing an aluminum exhaust and bragging about how light it will be; it's lighter still when when 1500*F rotary exhaust stream causes it to melt and fall off. Might as well claim to have a perpetual motion machine to provide the world with free energy as boldy state it will be a 400 hp streetable NA 2-rotor like it's a proven fact. If it proves out I'll congratulate him despite my humbleness for being wrong. Until then I have my doubts and if you're too immature to handle it that's just too bad.

Fellas,

I understand when idea's clash, people get pissed. Go take a smoke break or a breathing exercise whichever you choose.

Next personal attack, name calling etc will result in a vacation from the forum.

Thanks

Travis

A strong unported NA Renesis 6-port is about 150 RWkW (200 hp) @ 7500 and the power isn't falling off after that either.

400 hp NA from there might as well be Mount Everest on a bad winter season without any equipment ..

Ha, 400whp NA? THAT ain't happening. With my setup, I'll be fortunate to break 250whp (being realistic here). But, the optimist in me is hoping for more like 270whp (with water meth and appropriate tune.)

And look, I'm not here to swing my nuts around and brag about my build as if it's the best thing since sliced bread- far from it. I just felt like there might be others who have similar projects or at the very least ideas who may take interest and brainstorm. I've already got the technical aspects figured out, it WILL work. The real experiment will be finding out if it yields greater power than a standard ported MSP. Time will tell, and I will share my results regardless of the outcome.

Also, for what it's worth- my friends NA REW FB (REW block, GSL-SE front cover, Renesis eccentric shaft, S5 NA rotors, mild street port, Racing Beat long tube road race header, catless mid pipe, custom cat back, LS2 coils, Haltech E6K, S1RX-8 transmission stock diff with 3.90 final drive) made 196whp on a conservative "quickie" tune for 93 octane. Considering that my build will have higher compression, already has larger intake and exhaust ports (further porting the primaries, cleaning up the secondaries) and will be tuned for water meth, it shouldn't be a problem to break my 250whp goal.

Well sorry, apparently I got you crossed up with lpot regarding the 400 hp output claim.

If RB would release some aluminum Renesis-based housings it could make things interesting ....

No worries. And yeah, that would be the cats ***! If demand was high enough, I'm sure they would commission a batch, but considering how frugal your average 8 owner is, and that their aluminum irons for the REW are $1,400 a piece, I don't see that happening any time soon.

truth is i wanted to say 500, i said 400 to keep from getting laughed at. bah ha

500 would take.. lighter rotors.. and being able to rev to 15k. which is uncharted territory.

i don't consider what i know and what I've put together an opinion. how is an building an experimental test engine an opinion.
why guess when you can test. like i said, sure they're will be hiccups, but that's what separates the keyboard mechanics from the real world problem solving engineers.

His opinion is it will work, moving foward on it is simply applying action towards that belief

Understanding the realities of the physical world doesn't make someone a keyboard mechanic. Again, some of the most experienced hands-on rotary engine professionals considered the idea and based on 30+ years of building, experimenting, and pioneering they don't think it will work. The only keyboard mechanic here is yourself ...
