Afternoon,
Here are the results from the E&H Motors v11 subaru, install pics also.

I'll post dyno sheets in here tonight when I get home from work.

Carl Ruiterman (co-owner of E&H Motors) reports that the car is very fun to drive, the turbo operates like a light switch. You can see how quickly the turbo ramps up even on an 8 second run.
With the dyno in hold mode at 3000rpm, the EFR will make and hold 28psi of boost, making 200whp.
The gtx turbo wouldn't make and hold this much boost at this rpm, it would cough and splutter and surge.

Please note this is on a near stock bottom end and we will be pushing the setup harder once the high rpm forged EJ20 is built.

Enjoy, video's to come.

Cheers, Mike

 

Looks like over kill but it looks good nonetheless

I have always gotten my boost source from my compressor housing with great results, even on my "junky" pte turbos

 

overkill is good! i always did compressor housing too, but would always have boost drop at high rpm's. i would think it would be more linear after the intercooler, but more prone to boost control issues and spikes as it has less time to react. thats why im going with the licp instead of the intake manifold.

 

 

Bravo! That's a test! The supra guys should take note of those overlayed boost plots!! The gtx has a tiny turbine housing on it compared to the efr. But it's good to see it still outspools it.

 

The boost curve is from another screenshot, i copy/pasted it on the bottom to make it easier to read

From the sounds of it Carl is really happy with how it performs.
Our local track Hampton Downs has two hairpins.
He usually exits turn 9 in 2nd gear, but now he said you can exit in 3rd gear with some pre-emptive throttle input and it absolutely rockets out of the corner. He said the boost ramps up really hard. I'll have to get him to do some logging to show what i mean.

imo the most surprising part of the whole equation is the 28psi @ 3000rpm is makes in "hold mode" on the Dynapack dyno. That's 200whp @ 3000rpm. Obviously it's loaded up, but the fact that it can do that is amazing.

Personally i dont think this setup is maxed out yet. The torque curve isn't massively diving, it could take more boost.
I'll be getting in touch with Geoff@Full-Race, hopefully i'll get Carl to fit a turbine speed sensor to keep an eye on shaft speeds.

We are now looking for a 8374 for testing and development
I'll guess we'll just have to get in line!

Cheers, Mike

 

^ you, me, and all my friends.

550whp isn't bad! You guys were picking up 10whp per psi at 28. I know denkers was running 28psi out the top end with a 2.3l and huge cams, I would think your 2.0l could run 32psi + out the top end.

What fuel mike?

 

Fuel is Gull Force Pro (E85) that comes in 200Litre drums.
It's 15% 95RON gas and 85% E98 (denatured Ethanol).

 

That supra test was a damn joke.

Mismatched everything, no boost plot, and different information on the same thing throughout the thread.

I got a 6266 in the shop so once my car is up and running I'll get a back to back with it against mine. Both will be T3, SS (sorry no TS) and same A/R's.

 

Dynapack is hub power... 6-8% less than wheel power... due to slip.
Just saying... dynapack is very nice for tuning.

 

Sorry 550 at the hubs. I was just converting it for other Americans

 

Bah - can't delete my response, for some reason I was thinking of Alcotane when I wrote my first reply - ignore me

 

Borg Warner EFRs are scheduled to resume shipping in August. This long wait (1.5 years since the launch) has not been easy for Full-Race to work around. The fact that the EFR's are that good is what keeps us hanging on. As of right now, there is nothing like these turbos on the market. While there are different brands with comparable dyno charts, none have integrated wastegates, built-in BOV, stainless turbine housing, titanium turbine wheel, high grade bearing, etc that the EFR comes standard with. We are grateful to everyone who has remained patient, as this has taken a good deal longer than any of us could have anticipated.

the way EFR's respond to throttle input is remarkable. By cutting the rotational inertia in half it makes for a noticeable improvement to any experienced driver. An additional benefit (as you found) is the power it makes at low rpm under heavy load is very high. This is similar to what Mark Shead saw on a twinscroll 7670 months ago. Ive been fortunate to daily drive my EFR evo every day and I just keep grinning

thanks mike - I would be interested to know what your shaft speeds are running at on the 2.0L subie. You are not alone in looking for that 8374 but hopefully we can fill the backorders quickly and make this waiting game a thing of the past

 

geoff, you gonna set your 8374 to kill soon?

 

we just got a deal with Ford - building some ecoboosts for SEMA, so my evo is literally my daily transportation at the moment. I havent had any time to work on it, just driving it and loving the car. When i find the time i will install a walbro 416 fuel pump and push it harder, but thats not going to be until august more than likely
