A lot of *****ing and moaning that theres no EFR results/data in here but when somebody (with credibility I might add) shares its dismissed? Go figure... I guess the only logical conclusion is the US tuners are 15% better than everybody else lol

Many more dynos/tuning projects, besides RTErnie's extensive knowledgeable & expert attempt to maximize EFR7670, have shown to not be able to reach 600whp DJ, so even fueling aside, it would be less-than-accurate to speculate how much does this dyno-test would read converted to DJ.
If anything, 550whp is awfully close to the 575-580whp max readings by past EFR760 E85 maximized readings, in Killer Mode- exceeding 29psi of this test.
If anything, I'd venture to guess this dyno reads DJ: RTErnie was at 34psi..5psi more could easily pick up 20-30whp? Of course!

The Evo I posted, made 368kw/493whp at 25.5psi, using the 15% calc that comes to 567whp DJ, which seems very plausible to me!
I have all the data in the world I can share if you like, i'm not trying to turn this into a measuring contest, I am simply stating what the conversion of power is between the two dyno's.
I have 3-4 other EFR setups that i'll be finishing in the next few weeks, that will give you a little more to laugh at!

RTErnie made 557whp on that 'run-in' thread at ~25psi by the looks of it at around 6800.

The question was about the 15% DJ correction factor, not the car.

Sorry to give you a hard time about it. Its just beyond what I've seen for this turbo. I had some discussions with Eric about his best 7670 results before he sold it, and he never got much above the 550 whp DJ. He thought the best he could get was around 575 whp. Not sure if it was a wheel speed limitation or something else. I also discussed the 7670 with BW, and they said the 7670 wasn't as efficient as they had hoped.
I've tuned nearly every combo around, a 9180 went 737whp (830-840whp DJ).
2.4 with all supporting modifications, 35.5psi boost, 112k shaft speed (basically maxed.)
That same car ran 148mph
. Seen em before but there's likely never gonna be one.
