Full Race Twinscroll T4 rotated turbo kit
BorgWarner EFR 9180 EWG 1.05 T4


Finally got to put the EFR through it's paces. I had previously run the S300SX 91-79 .91 AR on the car and was pretty happy with it.
I am AMAZED that a 94lb/min turbo is spooling 400-500rpm sooner than the older 82lb/min turbo.
On the first trip to the dyno last week I ran my 2007 STi RE090 tires which have good tread but are very dry. The car made 805/636 SAE at 33psi, but I suspected the tires were spinning. Here's a graph of those pulls:



And a graph vs the old 91-79- The 91-79 was at 34psi.



I decided to try the dyno again yesterday, this time with my drag radials. The results were that the car held traction better to about 6500rpm, then let go hard. The tune and boost were untouched from the previous dyno.




Now, SAE numbers are great for bragging rights, but we are at 5400' and our correction factor is pretty high. Here is the uncorrected graph, which in my opinion is still a lot of power for this altitude, at only 33psi ( I want to run 37-38 but need traction). A stage 2 STi only makes 250 uncorrected on this dyno.





Someone want to help me embed these?

Nice car!

This is making me anxious to get my Borg up and running, your car makes me think I might have actually been under-estimating the power band my S400SX is going to end up with.

Wow! Looks great! Love the top end. Any plans to rev it higher? Maybe do some road tuning if you can't get it to stick on the dyno?

Here are the embedded videos:

I will rev to 8500 and once it warms up I'll tune it on the road. The tires spun at 21psi yesterday because it was so cold.

Evo's report an exhaust restriction at around 750whp when running a 3.5" diameter. What are you on, and do you think it plays a factor?

Edited because of Geoff's correction: THANKS!

Seems like I'm fine with a 3" exhaust, egt is 1400. Still running a full TBE too, no cutout

disagree - 3" is perfect for up to 750WHP.
from 800->1000WHP 3.5" is the call.
for 1100+HP 4" is the way to go.

^^^But Geoff, what should I do for 1000-1100? j/k




With all this wheelspin talk, did you log RPM vs. mph (or any type of speed on the dyno)? It'll let you know if you're spinning tires (or clutch or tire on rim). Most overlook tire on rim issues but you may want to mark. It is one issue we ran into on the Turn In Concepts time attack car last season and you're running more power here than we ever used on the track.

Awesome numbers! Should be great to see what it does at the strip.
