Glanced over the first page, then skipped to the last page....just to find some e-fighting

So....I have a spare Renny block that I want to rip into and play with some porting, looking for suggestions on Bridging the Renny. Bridge the sleeved 6 ports only? Try the Primary's only?
Enlighten me.

Oh just so everyone knows, I'm not a newb at porting Rotaries, have been doing it for 10+ years now.
I'm building and porting the Renny engine for Modified Mag's "Project RX-8" currently.

the e-fighting usually results from people demonstrating no common sense in their postings. I'm sure the people doing it as a business will rush in to tell you all their secrets, especially in light of your complete lack of research or wanting to do it yourself and demonstrating what mad porting skills you have rather than testing and promoting their concerted efforts and business enterprise directly.

:facepalm:

Wow thanks man.

I wasnt looking for BDC or Eric to just hand over pictures with measurments of bridge porting haha.

Thanks for putting me in my place I suppose?

The first Renesis Bridgeport I know about started before any I am aware of here (USA), done in South Africa by S1 member Philip (a mate) and long term rotary owner (RX-7), the South African "specialist" removed his Bridgeported engine a number of times after a few failures the long term conclusion and reliability was not great...in fact it failed again eventually and was put back to stock and car was sold....Philip now owns a Subaru WRX as his work DD.

do you know what! he probably did search but got nothing but a bunch of threads with yours jeffs and charles ever lasting e skid marks that never go away and ruining a good thread.

i have an idea how about you jeff and charles start your own thread so you guys can squable as much as you want, so we can sit back with a bucket of popcorn and watch when ever WE WANT and the threads can stay on track instead of you guys shitting in every descent thread on here.

We get it team your trying to stand up for the little guy but im sure im not the only one that is tired of seeing you guys getting into it on every good thread.

Joe R.P.M has probably forgotten more about rotaries than you will ever know.so instead of saying search noob share some of that vast amount of knowledge you guys have and the development of the rennie might go along a little faster.

Knowledge is power but only if you share it.

Why are you dragging my name into this? I haven't anything to do with this thread.

I would like the thread to stay on topic too and I'm not trying to put people in their place. If you don't want something to be part of the discussion then don't put it out there. By your own admission you didn't even read this thread, just the first and last page with your own side commentary. This is just the typical stuff that goes on here, including some people thinking they have the right to post whatever e-skid marks they feel justified to add and nobody else does.

There are several subject discussions on this forum and the search button works the same for everyone. If you bother to put in the time and read through them you might have a better feel for the lay of the relative land and know where to direct your side subject to. I have no idea what Charles was getting at earlier. I guess he didn't like me calling out that we were off track, which BTW we still are and will continue to be at this rate. I blew up on the other guy earlier because he was trying to attribute the issues with the early 13B BP to a Renesis BP, again also with the "gotta prove I'm worth listening to" talk. The two BP engines are different in many ways, which was also discussed here and in other places on this forum.

Every indication is that Eric has moved on from the Renesis. That primarily leaves BDC Motorsports and reddozen. Red has some version of BDC's BP setup in his car, but he just drives it on the street and as far as I know hasn't put it on a dyno or anything else to help concretely define what the net effect is. Even then, he has no baseline reference. He replaced an old engine with this one, so of course it feels good. A fresh, detailed stock port Renesis would feel good too, but he may never have actually experienced a good one under the same conditions.

Eric's efforts involve a completely different racing EMS setup and was purely competition based with all kinds of custom stuff. If you read the thread then you know any comparison or veracity of the data which he so graciously posted here is equally hard to define and nobody held back saying so and that wasn't a problem then. Again in this thread, BDC is looking for damn near anyone to help prove out their ideas and extensive work in this area. If anyone cares to step up to the plate I'm sure Brian would love to talk to you. If anyone else is pursuing it, whether it is Ray or >insert whom evers name here< they haven't yet shared that with us.

Philip was mentioned. He never backed up any of his stuff concretely either before eventually giving up. That's basically where we stand as far as I know. There is quite a variance within the results of unported Renesis engine performance. Some people have a better grasp on getting the most out of the Renesis than others. The same can be equally true for a BP Renesis, such that an optimized unported Renesis engine thumping a non-optimized BP Renesis engine is entirely possible.

As also discussed earlier in this thread, what we really need is two engines built identically equal except one with OE ports and one with the BP setup and trying to optimize them within some std level of continuity. Even then we still have quite the debate to this day about headers, intakes, tuning strategies, etc. etc. I think that would make one hell of an article regardless rather than the usual fluff that never materializes, but that is something best pursued privately with BDC rather than as an all points rah-rah-rah bulletin here. If you had started your own thread with that post I would have just rolled my eyes and moved on quietly like I do with many threads posted on here and we wouldn't be having a popularity contest over it.

this thread is so off topic it can be anything at this point.i quoted team in response to his noob calling to R.P.M but basically if you where to search any subject in here thats all you will find.

but since your both here which thread would you like me to repost my post in?

scottish

iTrader: (1)

so you couldn't post this before you told him to search noob.

joe is a very well respected rotary builder here in canada.im sure if himself and brian had a chat they would have a lot of knowledge to share.

Well if he bothered to search at all he wouldn't need Team to explain it. In talking to most of the mainstream builders recommended by people on this site and on RX7club.com I have found that rotary engine builders often do not agree on a lot of things, especially when it comes to the Renesis, much like many of the knowledgeable members here.

iTrader: (1)

^well its obvious he did search and ended up in this thread, started reading seen all the BS calling and went to the end.if the more knowledgeable members here where not so quick to flame then more knowledge would be shared.

i'm from the don't spoon feed the answer to them generation too but as my current boss told me 7 years ago "you know you don't realize how close you are to being fired right now. i said what do you mean? he said you are the best most knowledgable guy i have ever hired in 30 years but you are of no use to me. i said ok why? he said because there is nothing i can't put past you, that you can't do and if you don't share your knowledge or listen with the lesser experienced guys, how am i to improve and grow my companys technical abilities? then you are of no use to me.knowledge is power but only if you share it.have a think about it and get back to me tommorrow with your answer"
well long story short its the best advice i have ever had and im still working there.

I didn't call him a noob, which would have required less effort than pointing out the obvious, though I can clearly see why someone else who was just midlessly reacting to his post rather than considering what was being said, might

Very true team. I had every intention of doing before and after dynos etc. The before dyno is what showed me that the old motor was a bust, so it was more or less a wasted dyno. That also made rushing to get a dyno / tune on the BP less important cause there was nothing to compare it to.

I'll do what I can to get some numbers to everyone after the first of the year. I'll post some air flow dumps and get a fresh dyno after we move into the new house. maybe they'll help someone determine if it's really helping things. Should I get a compression check too just to see what's happening in there? guess it wouldn't hurt to see what compression is after 6,000 miles.

You're not under any obligation to us for results or proof. Meant to post that earlier.

Jeff, Mark, and myself have all known each other on this forum for a LONG time and, given our individual passions for our interests threads sometimes turn off-topic and somewhat harsh in our tones with one another. This is normal in a society that gives a damn about itself. Otherwise, the RX8Club would be just another "ricer" forum. If one were to read more threads that the three of us have been active in, one would see a fairly balanced level of discussion and passion.

Joe RPM may soon discover that the Renesis is a bit different than previous rotaries. It might be unfortunate if he really HAS forgotten all that about rotaries, as he may also need to recall such information in his future exploits with the Renesis.

TeamRX8

iTrader: (25)

I would say he'd be more fortunate forgetting. IMO the most common mistake experienced rotary enthusiasts make is trying to force the Renesis into the same old rotary mold.

It also seems to me that most of our discussions are awash in a tsunami of passion.

Charles R. Hill

iTrader: (7)

Agreed on both counts, Sir.

I know I'm not obligated, but I need people that know more than me to look it over and help everyone else understand if it's worthwhile or not. I was willing to be a guinea pig, and I believe that everyone else has the right to know if it was a beneficial investment or not. My 8 represents the normal drivers car. So if anything, it'll help show the long term durability of such an extreme porting under normal daily driving conditions.

If you and Ray don't mind telling me what you want to see, I'll work on putting some spread sheets together. The more detailed the request the better. It's easier to pull and organize data once than several times. I gave Ray a call, but I'm guessing he was too busy to call me back. It's understandable.

The only way to stop speculation is to spread information.
