interesting comparison of EFR9180 1.05 (3" exhaust) vs EFR9180 1.45 a/r (open downpipe) on a 2.2L evo @44psi:



interesting to see similar spool times, but massive gains in the midrange. EMAP was not monitored on this setup. This is 115k turbo speed, pretty much everything the compressor is capable of

edit: DOH, just realized this was posted above :hammer: #repost

And he goes quiet again. This is a 6 year cycle now guys, do people not see it? I don't want to tear the guy down, just people need to open their eyes and see who the person really is that is quoting all this information like its fact.

I hope he didn't blow engine number 6,7 or 8 whatever it is at this point. I'll never understand why he doesn't speak up, defend himself and post what is going on. He doesn't owe me anything, I understand that. However, it looks ridiculous after 6 years of the same status quo.

Hopefully someone will throw one of these 9180s on a 3 rotor and convince its actually worth it to do the swap.

Starting to feel the vibe that maybe the motor did let go. Not everyone can turn book smarts (theory) into reality.

bumpstart

the pattern i see is the same old names sticking the knife in, off topic , some of them mods

in that situ, motor still alive, and being a forum vender, one whose moneys keeps this forum online
then i personally would have turned my back on the entire forum long ago

as is this thread, with more than 10 reported off topic and abusive posts, has not yet been cleaned up by the only mods with the power to do so

a bit telling , either someone isnt doing their job,, or secretly holds an agenda

the motor blown or not has nothing to do with this thread , as it is a thread about the real performance laid down with these turbos on a dyno

something we will not get from howard now , thanks mostly to off topic posts like yours

keep it on topic. or i flag your posts .. simple

Apologies in advance as I do not mean to further stir the pot, but doesn't the motor being blown or not have everything to do with this thread?

Reason being.. well you already hit the nail on the head. The thread is to discuss the real performance laid down by these turbos. If he can produce a dyno chart with impressive readings but then 150 miles down the road, the engine gives out, is that dyno chart really indicative of the performance these turbos can lay down? At what point do we value sustainability?

In order to prove the performance of these turbos, you need it to be operating in 100% working condition, otherwise the results are immaterial. Blowing an engine does not equate to operating in good working condition, so what good are the results that are (temporarily) produced?

So the TL;DR is that I would argue that whether the engine has blown or not has everything to do with this thread.

Let me get this straight.....you are saying he hasn't posted dyno results in 6 years because people are asking for results? Haha. Yes, that must be the reason we aren't seeing the "results".

Jesus man, open your eyes.

Not when it's speculation. There could be many reasons as to why HC isn't posting at this time.

Yes but the problem is that when you start a thread with heavy anticipation of results to come and then just leave everyone hanging for weeks, speculation is going to happen. That's how human psychology works.

Could the engine be in perfect condition? Yep. Could it be blown? Absolutely. Especially when you look at historical data. And as mentioned, whether it has blown or not has everything to do with this thread. People are just talking. Of course when results or updates aren't posted for weeks on end speculation is going to occur.

Do you live in a world where everything is sunshine and rainbows or do you realize that things can go horribly wrong? There is nothing wrong with discussing the possibility of a blown engine or any other negative outcome in a thread that directly concerns it. I don't understand what you're trying to get at with that post.

This topic is about the EFR 9180, not about speculating if Howard blew his engine or not.

I don't care if he blew his engine, and if it did blow, its got nothing to do with the results people are waiting for in this thread, other then the fact that a 9180 was being tested..if it happened.

Your quick to bash Howard and take cheap shots at him (in other threads that have nothing to do with this, or howard nontheless).
I would like to see what you have contributed to this forum that makes you feel you are in any position whatsoever to talk down or take cheap shots at someone who has given a lot to this forum. You may not agree with with his theory, and that's fine. But wheres yours?

I see you as nothing but an arrogant newbie. What the results arnt coming quick enough for you? Are you really "hanging on the results? really?
Why don't you get it sorted and post some of your own then?

One thing I have learned over the years with rotarys and this forum is patience. Howard looking forward to results whenever you decide to post them.

Answers in red.
But now I can understand where mods are coming from when they don't like bickering in technical threads so if you have any more sorting out with me following my responses, please feel free to PM me. I check the site about 2 or 3 times a week.

Looking forward to the comparison, looks promising.

-yes I am still interested in results and believe some information could be taken from the results even if the engine blew.

Cheap shot was in this thread here;
https://www.rx7club.com/single-turbo...s-use-1080803/

You wrote "do we need to get Mr. Howard Coleman in here to show us the calculations for exactly how much fuel injectors and pumps he need to blow his engine?"

having a running car is not really results...i have a running car..its been DDed for many years now, and im sure still interested in what he has to say..and i would not think less of him if his motor did go.

anyway im one of the people who wants this thread to stay on topic so...patience.

Guys, everyone on this forum is free to share their opinion as long as it's not an overt attack or needlessly nasty. Censorship by the moderation team should be kept to a minimum, unless in the case of racism, vulgarity etc.

Let's remember that we're all part of the same community, and don't post something from behind the keyboard unless you would also be willing to voice the same sentiments at a public car meet.

My 2 cents

TwinGTR

On the Swedish forum for rotary enthusiasts www.wankelregistret.se we have the rule that you must write your name and location in the signature, it helps a lot in this matter. Something for the moderators here to consider I think.

Funny cause atleast one post of mine was removed in another thread where I was supporting RenisisFD. It was written in a respectful manner reminding HC results trump theory and he should consider going back to the garage to work the cars issues out and report back with some numbers. Instead of posting up overly long threads on stuff he speculates about...

Example...

On paper the rx3 shoukd be a heaping pile of junk on the track compared to other cars of that era that on paper, were better, yet for racing the 3 was the favorite...

Some mod must have thought it was a personal attack and deleted it...

No pm was sent to me saying why it was deleted either, if it broke any rules...

For some reason it seems they just want to sweep certain things under the rug..

Above my 'pay grade' I guess

I hooe as a community as a WHOLE, we work through this BS and become stronger from it...

Only time will tell...

Cheers.

How does one even become a mod? It seems some don't give a crap, and some go overboard regarding these issues. Not sure if there is a section for this question bit I thought it relevant.

Thank you. I hope that moderation of this forum stops being team sports and becomes a platform that promotes discussion.

Howard Coleman: I respect the time, money and effort that you've put into this project, and I implore you to please keep us informed. I hope all is well.

It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat.”

I can say for sure that the transient throttle response of the 1.45 a/r rear on the 9180 is no where near as good as the 1.05 rear.
Fullboost seems to be very close/similar on the road but the boost leading up to the point is not as good. Off boost response is not as good either.
