Default EQ - Borg Warner EFR 8374 Build Final Results - Over 700whp!

Here she is after WAY too long!

We finally got all the fueling issues settled with an A1000, surge tank, and all new -10 lines from the back. Of course that worked like a charm and we now have all the fuel we need. We then had set back with the Spec clutch as it completely let go at about 27psi of boost. We then went with the new RPS carbon-carbon twin disc setup to hold the torque.

So after all that waiting, some fresh oil, and a final check, we get her on the dyno today and started cranking things up. We ended up at 707whp (601whp Mustang Calibration) at 32psi! The turbo definitely has more in it, but this is a great place for the car to be.

I'll grab a boost chart on Monday, but it was hitting full boost in the mid-high 4's on the dyno. I'm curious to see what it does on the street. Really phenomenal spool for this power level! We're running the MAP H11 studs.

My opinion the best graph from all the recent big power cars. Congrats. I am convinced are cars need the t4 turbo's now from your graph and the one from mine. Again good job!

Thanks guys. I was really impressed with the spool and especially transient response of this turbo. Especially considering the rest of the setup and the overall power potential. I think this thing has another 50whp in it fairly easily.

Thanks! I'm hoping to extend the redline to 8k RPM but I think we'll need to pull the catback to let it hold power up there.

pretty impressive results.
how much you are getting at 1 Bar of boost (14 PSI)?
i know this is a subaru forum. but doesnt hurt asking would you expect similar result on a 1JZ?

I'm not sure what it was at 1 bar. I don't know anything about the 1JZ, but as long as the motor can handle it, this turbo will do it.

Just did a little road tuning... This thing hits 30psi by 4300RPM in 4th gear! Also hits 24psi in 1st gear! Really impressive!

Could you tell us what clutch and flywheel you use?
I have a project for 600whp, and my ACT Xtreme is not so good now...
Thanks!

We ended up with the RPS carbon/carbon clutch and flywheel combo. Amazing setup! Please let me know if you're interested in it and I can get you pricing.

Thanks
