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?
