BorgWarner EFR 8374 IWG Dyno Results
#27
Tuned a 13B the other day with a 6266 Ball bearing.
It was slower to spool then the EFR9180 i just finished tuning.
Anyone comparing the Precision to any of turbos in the EFR series is kidding themselves.
EFR has crazy spool properties neither Precision or Garrett have.
Can anyone here build 30psi at 5000rpm in 1st gear with any of there GT42 or 6766 Precision's on 93 octane? or even e85 for that matter.
I doubt it.

515rwhp was the max recorded. We have a ported motor going in now, and we will be testing all 3 turbochargers back to back( 7670/8374/9180 IWG). I have all the turbochargers here ready to go.
@515rwhp it also makes 450rwtq( similar to what cars making past 600rwhp make). Also since it comes on so early, it is much faster than what your standard 515rwhp feels like. Just watch the videos...

the above dyno suggests the 8374 can make 15psi at 2800 rpm.....will it still spool that quickly on pump gas but the boost remaining at 15psi?
Also whats the highest boost you can run safely/ reliably on a bone stock motor with 99 octane pump gas with the 7670/8374?

One should still see 15 psi by 3000 even on pump gas. That car in the video makes 20psi by 3000 on e85. Keep in mind the porting combo, configuration etc has an impact on this. You cannot find a faster spooling turbo system on the planet, not a soul has been disappointed with one of our kits.

You should determine your max PSI, if running a REW, on your apex seals (always debatable) and the confidence of your tuner. Some people have run 30 psi on stock ports with AI and pump gas, and many have blown up at 15 psi. Find a good tuner and determine his confidence level.

for a purely street fd with stock port what is the better turbo overall 7670 or 8374 at 15psi on pump gas? also whats the highest boost that can be run on stockport engine with oem mazda apex seals?

I would run this, even at altitude I like the EFR8374. the 7670 is also a great option if you do more autox, tight circuit stuff. the efr8374 is like the michael jordan of basketball. He has a good vert, he can dribble, can shoot, has hands the size of a gigantic person, and knows the game. the efr7670 is more like a point guard who isn't as tall but can do almost all the same stuff (isiah thomas?).
