It's good to see this thread isn't hijacked
I'm more interested in the new topic anyways.
Side note, isn't it around 13K that our engines become resonate and literally shatter due to vibration? Anything under that I suspect is fine, just tuning dependent and more chances for bad things to happen.

I am pretty sure they can go fairly high, that's what makes them so awesome for airplanes?

Some of you need to lay off the BS because to me, you sound like a big ***.
I built a few cars/motors in my past and have never delt with this kind of stuff on forums. It really shows what kind of people are in this community. Do you really want newbies to see you this way?

that said, the part of the problem that YOU are able to do something about is to equip yourself with relevant knowledge. you keep referring to what you've done in the past with receiprocating engines. I think 9krpmrx8 said earlier in the thread (i'm not sure though), and it may seem harsh, but pat yourself on the back and get over it. very little of that experience is relevant here. hell, if you had Rx-7 or old-school rotary experiences, you'd still need to park some of that accumulated knowledge at the door.
you have a tendency to ask a question while making a statement at the same time. you have to choose one or the other. period. you claim to be researching, and I won't sit here and call you a liar, but maybe consider citing some of your references. on the first page, I know someone had posted a link to RB's experiences with apex seals. you then went on to propose that you were going to use carbon seals with your turbo'd/nitrous engine. do you see what i'm saying?
it is my willingness to help a newbie (and you can look at my post count and scoff, if you like) why i'm even bothering to type this. not everyone is here to poke fun at you. get over it.
No I don't have all the answers. That's way I started this thread, to get the most up to date info as I build. 3 year old threads are not going to cut it.
Some of you have given great info and I cant thank you enough for it. Some of you need to get your wewe wet, get back to your man hood and stop acting like a women

common sense should tell you that if significant forward strides had been made since the older threads were made, then chances are it would be posted. the problems with turbo'd MSPs are still current problems. true wisdom is learning from the mistakes of others.

herein lies some of the problem. i'm not going to comment on what some people are saying to you other than to say this: if you're going to be into Rx-8s (or rotaries in general) and plan on being around the boards, you need to learn to have thick skin. period. I may even go so far as to say, if it were not for some of the comments you find so offensive, this thread wouldn't be bumped and it would be left to an abysmal fate.

no one expects you to have all the answers. they just expect you to come to the forum prepared to post something that makes sense or engage in a discussion (relevant to an MSP-powered Rx-8) on why you think it made sense. if old threads aren't going to cut it for you, then perhaps you're better off selling the car and looking elsewhere - and I don't say that to be mean. you've basically admitted no taking in information because of a bloody time-stamp!

That is the point of the thread is to get relevant knowledge. The reason I keep saying I have had projects before is so we can pass "how the cooling system works" "what is CR" What should AFR be at" the basics of every motor.I need to learn this particular motor and its capability's.
I ask questions and leave statements for, asking a question and giving more info what I think about the question. Try to have fewer posts on the common sense answers.
I want to build and have (not expert advice but) up to date people that experienced the process. I will take pictures and videos, get every part up to spec and show the process of doing so. This is were you guys come in and give advice on tips and tricks of it (like the top bolt for the trany, thank you very much for the heads up ) What parts are best and figure out the best reliable HP.
The reason I said carbon seals is that they will fail under detonation. They will hold a higher combustion but will break from shock (detonation). I thought maybe I could slowly tune to not detonate but then realized that's not being realistic. I just read about some other seals to look into from a post above. Will be checking that out after this.
I felt like it was high school again with the "poke fun". It irritated me and I'm over it. There just stupid pointless comments/post. I have kids that do that and trying to get them to stop. I didn't expect to see that here.
I have a good time frame to do this project. I said in an earlier post that I normally do this in the winter. So I have more patience and not have the erg to drive it from the snow. Well now I want it done. I don't see anything wrong with a fast passe. Spend 4-6 hours a day instead of 1-3. I'm more of a hands on learner and which is way I want to open it up before I start asking more questions. I need to see what I have and what parts are good.
There is always a possibility to make anything work. Its not about the "significant forward strides" its about the cost to make it work. I was wondering How far you can go at what cost. If there was a break through, yes it would be all over the place.

I didn't flow-test ported exhaust ports but the problems should come from them and from the intake manifold. That thing is great for a daily driver and really makes the engine's midrange decent but when it comes to just high rpm driving it could benefit from a tweak or two... or itbs

Here is my data logs doing a 3rd gear and 4th gear pull.
On these two runs I came close to redline, but this gives you guys a general idea that she makes power well beyond the factory 8500 rpm threshold.
Also my plugs are status quo at the moment. One more tune from MM , and i hit the dyno the 25th. 31st the shop is closed.

Cannot open.
I have yet to see a dyno of a NA Renesis continue to make HP past 8500RPM-9000RPM.

I have never seen one that holds where it is at, they always fall off and that is by 9000RPM, I imagine in another 1000RPM it would fall off even more.
Even on Mazsport Scott's ported Renesis dyno graph, and you know he is trustworthy.
Charles Hill ported + Nitrous. Still falls off.

Do you have excel? It opens fines with that program. I just tried it and I am at my job , created the file on my laptop over the weekend.

9,679 (add 500 rpms to the tach and your at 10,179 rpm) is as high the ecu will allow the Renesis to go. MM tried to make it 10,500 rpms(tach reading), the ecu literally resets itself. The Renesis will spin well into 12k rpm territory if you have a stand alone , the stock ecu can't be tuned to go further than 9,679 real rpms, not tach rpms.The datalog I gave you I never tried to push it to , 9,679 rpms. I do have a data log that has that data if you want to see that.
If you look at the data the MAF numbers go up or hold steady. If there is a little inconsistency in the upper rpm, doing 2nd gear and 3rd gear runs on the street means your doing well above the speed limit ,so started to lift a little at the end.
