Excellent! Now we can start seeing some results one way or another!

 

Button her up! Whooo!

 

Instead of grown men arguing about the OP not posting results, Why not start a new results/feedback thread at let this thing die out? Its obvious the OP is over his head with the build and rather not hear negative comments. just a suggestion

 

Or people could quit posting suggestions like this and let that die. This thread is fine. Howard is online right now if he wanted he could chime in.

This thread is about a Turbo NOT the OP.

If you would like to debate your point by all means take it to PM.


Now lets see some more results! Whoever they come from Eh!

 

I am also still interested to see thoughts on the GammaTi Turbine wheel!

 

ArmenMAxx Curious how the response of 9180 will be in comparison to the 8374. At the same time I really want to see the power curve of 2 rotor 9180 iwg w/ a Semi PP.

The added overlap and resulting air/fuel in the exhaust of a semi-p-port would REALLY give an IWG a workout. I don't see that working out unless your target boost is really high.

High boost would be fine for a drag semi-p-port, but you would need a couple EFR 9180s for a fast drag car (550-650whp isn't going to cut it). For a track semi-p-port I think you will want EWG still and low boost (~22psi race gas or ~24psi E85).

But uh, just spouting off unfounded opinion.

chibikougan I am also still interested to see thoughts on the GammaTi Turbine wheel!

Surely trolling? Gamai Ti exhaust wheel is what the EFR turbos are all about....

The generous exhaust side sizing and Gama Ti wheel work insane with the strong rotary exhaust. My EFR 7670 was 300ftlbs by 3,000rpm, 380ftlbs by 3,500rpm and over 400ftlbs before 4,000rpm.

That is LS V8 torque by 3,000rpm- pretty good for our torqueless wonder of a rotary.

 

Surely trolling?

Thanks for your comments on the Gamma Ti wheel though we can do without the little quips. You clearly have some issue with me if you would like to talk more about that issue please feel free to PM me about it.

Now more about this the EFR turbos and the Gamma Ti turbine wheel and shaft combined with the Milled billet compressor with extended tips..

Thoughts on longevity?

Results?

Hopes and dreams?

No, I have no idea who you are nor do I care (though I have a little chubby for your avatar of Bubbles)- just simply surprised that the Gamma Ti exhaust wheel is news to you as the BW EFR turbos are pretty hyped and the Gamma Ti is their advantage/selling point over the Garret GTX line.

My experience with the EFR 7670 is that the Gama Ti wheel does help spool quite a bit on the rotary.

Feeling the material (hardly objective), I don't think it will have good durability versus foreign object damage (feels/sounds more brittle/ceramic like), but so far it does seem durable against high EGT. I typically run a lean cruise of just over 1,000C EGT pre-turbo, but very low EGT ~700-800C under load with a very rich >10AFR. So, unstressed I can say the Gamma Ti can take the heat as I did some road trips- I have no experience with high loads and high EGT though.

Unlike earlier ceramic exhaust wheels (Nissan Skyline turbos) the Gamma Ti blade thickness increase over Inconel isn't so much as to impact flow and they seem well bonded to the turbo shaft so they don't spin off with high boost/harmonic resonances.

The compressor aero does seem very biased toward high pressure ratios like typical BW stuff and like the Garret GT line. I didn't make much power at low boost like the old '50s tech 60-1 wheel, but then it didn't choke flow at 18psi like that 60-1 either.

So, I would say- the compressor aero isn't really the bees knees for a rotary on 91 octane-

except for the fact that you can run a size up compressor wheel and still be equal or ahead on spool thanks to the Gamma Ti exhaust side.

Our engines just aren't up to the task of a modern turbo in regards to knock resistance on pump gas, but going +1 on EFR turbo sizing can make up for that disadvantage (check out JacobCartmill's thread on his EFR 8374 @ 12psi VS Precision 62/62).

Results- you can check out my thread on my EFR 7670 experience and decide for yourself whether they are hyped or a real evolution of turbo technology. You can check out JacobCartmill's 8374 thread, shawnm565 8374 results and rx72c's initial 9180 results.

 

I just took our efr 8374 kit off our roadcourse car. I personally did over 15 hours of wot dyno tuning, it did several full events and was pounded on the street. Zero additional shaft play, no oil leakage etc. Not a single EFR we have sold has failed. We sell quite a lot of them too.

 

I have checked all of those and more. This thread is not just for me it is for the community remember that.

Thanks for the thoughts and info!

More Input!

 

Nice lets see the next on the list!

 

^ As quoted by chibikougan in post #232 "This thread is about a Turbo NOT the OP."

 

I guess Honda would also not be looking for a pessimistic critic like yourself to help turn their racing program around..... but they will turn it around with good people that will then be called visionary.


Back to the rotary community-

If we really think about what makes this or any forum great.... it is the information shared. And the easiest way to gauge who is most responsible for this transfer of knowledge is the starting of Threads.

So I would ask a question of everyone (but especially the critics)....

What is the best Thread that you have started?

Which one added the most information? Helped the most people? Save the most engines?

And here is where we have a real problem...
The critics seem to have very few (if any) informational threads...
And these same critics discourage those that are providing meaningful information from doing so.

So yes, I do back those on the forum that are producers like Howard Coleman and I encourage them press on.

..... want to guess how many meaningful threads he has compiled for the community?
..... now compare your thread numbers

Not real sorry for the rant,
Barry

 

 

I guess we're different in that I value the QUALITY of information shared, where as you appear to only care about the quantity of threads started..

If you want to build your car based off an overabundance of incorrect information than that's your choice.

Frankly I could care less..

 

I believe what Barry is getting at is most critics never put up their own testing results to PROVE anyone wrong. It's really easy to sit behind a keyboard and do nothing but research and critic on someones else's work. Early on I was one of those who did nothing but research and thought I knew everything. As soon as I started getting hands on experience, I realized I knew less than what I thought. Right or wrong, these threads and this forum are only designed to pass along info. What YOU do with what info is entirely up to you. That's why I could care less if HC continues on this thread or not.

 

 

HC defenders assemble!Seiously is there a light that shines in the sky to make you guys show up? This thread is derailed and damaged more by the HC team than people who have a different opinion.


Who cares he is a grown man and can deal with it himself. If you have issue with what I have said feel free to PM me about it.




Edit: I want to add that all incorrect info as pertaining to vehicles should be corrected immediately. This is a community and not everyone is capable of seeing the issues that will cause them problems or incomplete information including some self proclaimed Gurus. This is the leading cause of Rotary unreliability bad facts jack. Also who cares about post count Copy/Paste informational threads they are not someones hard work and if they do it for a living they are not going to be sharing that info with you anyway. So just quit with the How many Help you Help this threads full of information have you made compared to HC no one cares. It is no different then attacking people because "Oh you have only *Insert Random Number Here" Posts you Noob. You can have a conversation about things and be non confrontational even positive and I think we all need to learn to do that better as a community.

- End of my Rant sorry. Also refer to if you have issue with my statements feel free to PM me and talk about it.


Now onto more EFR Turbo info.

Oh thewird.


Tick Tock Tick Tock.


The race is on thewird or Turblown! Not literally though guys take your time and button em up nicely.

 

Same can be said about some of the critic flys that show up to all of Howard Coleman's picknicks. You bring nothing to the table but germs and magets. Not your own data! Not your own testing! Nothing! You do nothing but sit around and leach off someone elses hard work, experience, and expense. Rant over!

 

I suggest everyone let it go for a minute. The supporters aren't going to change their minds and neither are the critics. If Howard wants to save face then he can post. Other than that its just going to end up with more bans and we are all adults. Discussion is perfectly fine but the tit for tat back in forth is getting ridiculous.

chibikougan.....!!! you are not wearing any Threads!

 

Why are you idiots so hell bent on who started the thread, rather than the content inside of it?

 

[QUOTE=Barry Bordes;11900943]

As stated as not to derail the thread any further. Please make all comments to me in PM pretty simple logic.

Oh and I DON'T CARE ABOUT HC OR HOW MANY THREADS YOU HAVE MADE IT MEANS NOTHING IN THE REAL WORLD.

If Team HC likes him so much why are you being the main cause for thread derailment? PMs Sent to the main culprits since they cannot read.


Now back on topic..

What kind of compressor and or Turbine housing coatings can you purchase with the EFR 9180?

 

^ claims to not care, yet keeps responding to people.
