New BW EFR Turbo Thread

Pretty much. That, or something like Mellon Racing. No EFR will fit the stock 8/9 Exhaust manifold. Its expected at that point to go custom or aftermarket company.

Here is a dynosheet (Dynapack hub dyno) from my Evo 2 with a 2.15 l (94mm) and Kelford TX 284 HL cams running E85. Turbo is a EFR 8374 single scroll internal wastegate.
Had a some hours yesterday for my car and did abit tuning with E85 and the new 3.5" exhaust. Ended up with 495 tq and 650 hp@the hubs (Dynapack). Here is the dynosheet with E85 and 30 psi of boost. Could not boost more due the actuator dont want more... Have a stronger dual port Forge actuator from Full Race that will be fitted.
Boost is 30 psi and is achieved @5000 rpm with a 500 rpm/s ramp rate. EDIT: I used 722 rpm/s...
Exhaust back pressure was about equal boost pressure@6000 rpm and rose to max 5,8 psi over boost pressure higher in the revs.
Max turbospeed I saw was 104.000 rpm.

I can do it next time I am at the dyno. I use DIN-correction as you can see on top-right side. I do never use any drivetrain-correction. I have seen other tuners use up to 1.25 correction on a 4wd to get nice numbers to show their customers
I believe 700 will be easy when I can crank up the boost alittle more.
What ramp rate do you use? I use 500rpm/s. EDIT: I used 722 rpm/s...

I dont think I can run accel rate as a superflow engine dyno. My dyno are from late 2006/beginning 2007. I sent a quote to Dynapack yesterday as they advertised for a software upgrade for less than 500 usd. Have not got any reply yet, so I dont know the details in the upgrade.
How is the accel rate on the superflow engine dyno?

12 second pulls, start the cars at 2k rpms unless they spool the turbo that soon... And in that case 1200-1500 rpm, til redline 7-7500. Which ends up being about 500rpms per sec. Does the new Dynapack sw allow you to run accel rate like a superflow engine dyno? Thanks! I'm just asking to see what you run and why to improve my own process.

I have a Dynapack Dyno. I set the run time based on seconds, start rpm, end rpm, and settle time.
You were saying you were running 500rpm/sec. I was wondering if Dynapack had a newer version release that did pulls in RPMs/sec rather than start/end/time/hold time as I'm used to.
The superflow engine dyno's you set start rpm, end rpm, and engine accel rate (500rpms/sec)
It's just a different way to accomplish the same thing. Just curious.

^^ EFR FTW. They spool so fast and give so much more power when comparing regular inducer/exducer specs. They're not even the same. A usual 54mm inducer EFR can probably flow as much or more than a gt35r with a 61mm inducer wheel. It's nuts, they're on another level when it comes to turbo technology. I'll never forget my EFR.

Still have got no reply from Dynapack regarding software upgrade....

nice work JB! Have you got to experience the transient response yet? It's WILD!
