BorgWarner EFR Discussion

[PRY4SNO]

A couple years ago I bought a v-banded, externally wastegated efr7163 0.85a/r.

With my stroker build almost complete, I'm eagerly anticipating driving this beast.

Who else is running one of these?

I'd love to see some data/videos/dyno graphs and general impressions of how they respond.

Josh's setup is actually what sold me on the EFR. The power curve on his 8374 is simply bananas.

Any chance you can post a copy of that?

EFR8374 is pretty wicked.

Spool valves to work if you tak the time to set them up properly

Big intercoolers with name brand cores are worth their weight in gold

type 44s squat like a MOFO, 225 tires produce the first awd wheel spin on my dyno when rolling into throttle at 7000

We can't wait for our CNC heads to be finish that basically mimick this head on this vehicle

Consuming nearly 6400cc of fuel a minute at 8000 rpm means 20 gallons have vanished fairly quickly.

034's 60-2 on the front pulley truly is a POS, it made us stop at ~610whp/450wtq at about 24.8psi

The dotted lines is our Billet k26 for reference. Yes, this setup is wicked.

Cheers,

Hank

Please delete.

I was trying to erase that from my memory.

Now I have another spendy part on my list.

Damn the Internet
