how does an EFR compare in size compared to an s366 ( .91 A/R)? Could it be a direct replacement? the s366 fits pretty tight with the manifold im using now ( greddy t78 ) Do you guys think i'd be able to fit an EFR 9180 on my current manifold?

driftinmx6 - for External WG turbos, EFR is similar Outer Diameter to S300SX. However EFR is longer in "axial length" due to the ball-bearing assembly and double turbine / compressor seals. EFR also has the BOV "lump" on the compressor housing to be aware of depending on your manifold and compressor clocking orientation

No, sometimes nothing is better than wrong info. Looking at the numbers below...

the correct comparative turbo exit air temps then are:

GT4904r 21.1 psi 163 F

9180 20.4 psi 179 F


it will be interesting to see if the billet 9180 pulls away from the 4094r at higher boost levels.

howard

You have two turbos listed here showing the compressor outlet temp at approximately the same PSI. Looking at those 2 temps at face value it would seem that the GT4094r is slightly more efficient but what you dont know is the inlet temp at the turbo, you dont know the altitude each test was done at, you dont know the barometric pressure, you dont know the flow rate of each turbo, you dont know the shaft speed of the turbo.

You really have no information whatsoever to make any sort of educated decision as to which turbo is actually better. Perhaps the outlet temp of the EFR is higher simply because the inlet (ambient) temp is higher. Or perhaps the EFR is doing much more work flowing a higher mass of air and thats why the temp is higher.

Thats why the additional info is important and some info can be worse than none.

The methods used in this thread to gather info are simmilar to a 3rd graders first science project.

You made a ton of valid points but, you could have also done so without the insult. smdh!

Anyone have an actual width in inches for the IWG version of this turbo? My 20b is moved down and back 5-1/2" and is centered in the fd chassis. So I don't have as much room on the exhaust side as compared to a stock mounted 13rew.

That has dimensional drawings with a couple dimensions which you can use calipers and scaling to find the dimensions you require.

Note: not all the drawings from the turbo index display as the same scale on your monitor.

I just compared 7670 1.05ar to 9180 1.05ar to see if it would fit on my set-up and they were the same scale on the monitor, but the 9180 0.92 you are interested in displays a tad smaller for some reason.

Scaling with calipers will work- just don't pop to another drawing with your previous scaling and expect it to be the same.

Compressor cover should be just under 8 1/4" at the widest part with WG actuator head tucked under the turbo and outlet pointed up.

I'm getting a little worried here. Any updates Howard? Hope all is well.

I just got my car up and running on the AEM Infinity and will be moving to the EFR 9180 this summer. Really want to get an idea of what to look forward to.

Even if he did blow an engine, So what?
Ive blown many of my own engines learning, its part of the process, Good on howard for having a go. He will learn a lot and if we are lucky enough we will learn a lot from him. People should get off their high horses and **** off.
Break it, fix it, learn. we all do it.

The more often you take th engine apart the better and the faster you can put it back together. These days removing engine from our RX3, taking it apart, cleaning it and putting back together and in the car can be done in 1 day with 2 people =)

I agree as over coming failures is apart of any process. I respect Howard as he's man enough to at least put his testing info out there for all to explore and learn from. I know there are some that love to do nothing but troll his post looking for opportunities just to bash or take cheap shots at his data. Those same people usually NEVER start how-to threads or threads concentrating on passing along their experiences. How ironic! Lol!

I deleted my response because its not worth it. What's ironic, or really not is the majority of the guys who defend him have also spent years trying to recreate the wheel with no real world results to show. Its always another "theory" or "estimation".

I hope he didn't blow the engine as I am really excited about this turbo and want to see the results. However, no one should be shocked after the last 6 years of seeing Howard's formulas and theories that some members would like to see real world results.

His patience is uncanny. I would have had an RX7 shaped candle in my driveway. I really hope he gets it sorted and has another go at the mile.

Copy and Paste numbers...


No info at all...


HC **** jobbers cars not working saying blowing up engines is the way to learn??? No


Still waiting on this amazing info..... 10 years and counting...

I had time to build blow and exhaust sleeve rebuild drive for a couple years then part out a car.

I am also a know nothing jagoff.

People have been banned for giving HC good advice and they all have running vehicles and many customers with running vehicles....

Sorry if you did pop your motor HC....If you proved anything its that your way is not the way to go...

I really hope you come back and post amazing things that where promised and are just keeping to yourself for now...


Also posting my Opinion is not a bannable offense..

My reply wasn't directed at you as I could tell you were actually concerned about the condition of his engine! It was Renesis who just had to include that 3rd grade level nonsense in his post (which was completely unnecessary). He was also the 1st person to derail the other 2015 turbo thread and started the **** storm that got people banned. You see a pattern here?

Anyways those that are trying to recreate the wheel try to make the world a better place. That's why we have 9 versions of Iphones lol.

Obviously the info he post is interesting for some of you to keep reading after all these years. Your complaining about waiting 10+ years for results from someone else???? Why not do something yourself and get your own results. JS!

No its comedy at best. I have and I am doing things myself. I just don't post as if everything is new when all of this has been done since the 70's if not earlier.

I am angry that good much more knowledgeable people where banned for simply disagreeing with HC and trying to help him.

Then the Blind followers gobble up his Copy and Paste from PRIs website and go OOOOOooooh. When a simple visit yields the same information.


Excerpt from his own website:

Sure, but just one more time... there are really 3 jobs that need to be done.

1. Identify the problem that injured your motor
2. Build a motor
3. Properly refixture and tune the new motor

If any of these three challenges are not successfully met the outcome is failure. As mentioned, CPR motors are family. WE want them all to succeed and this will only happen if the problem is diagnosed, an excellent motor is built and that motor has proper support and tuning.



Yet he has proven he cannot even do this on his own vehicle and when people much more knowledgeable tried to help they where banned from this forum and will never come back.

I pose the question has he done more Harm then Good?



I really hope and pray he comes back and posts some kind of something as I don't see how you can run a business on theories and random copy and paste numbers that even in this thread he has gotten wrong and was corrected by other members. It's amazing they where not banned also.

Sounds like another thread you can start a discussion on? I was on that thread were those guys got banned and from my point of, they were only bashing. There's constructive criticism and bashing. Those guys choose the latter and had previous warnings about it yet, you claim they were trying to help? Fact... none of us knows what's going on because he hasn't replied. I'm not gonna speculate and think something negative happened.

Fact I did not speculate anything on this motor. There are many many before this one I even stated I hope and pray he posts something.

I am rooting for the guy because it hurts me personally. If these people where banned for another blown motor when they could have helped him if he wasn't so full of himself and his jockeys.

What is the definition of doing the same thing over and over again expecting a different result?

This thread is the perfect place for this discussion. It applies in every way.

Turblown got it done. Yet everyone sits here on baited breath awaiting what we all hope is not another blown motor.


So again does HC do more Harm then Good?
