Default Tales from the Dyno: Wayne's super-strong Stg 0 WRX

02 WRX with Stg 0 kit (up-pipe, pulley and reflashed ECU). Made a surprising 210whp through custom tuning. That's 10whp more power than a stock EVO

Hey, can someone answer a stupid question? How do you know which line on a dyno plot corresponds to which vertical axis? Obviously in the case of the first plot in this tread (y-axis for HP = y-axis for torque) this is a non-issue. But in the case of PSI and AFR in the second plot, which is which? Do you have to know enough "engine dynamics" to know which curve *should* have which characteristic or is there some feature that I'm overlooking?

Thanks!

Well, if you look at the lower line on the boost and A/F plot you will notice it starts at 13, then moves down to 11 as the RPMs get higher, this is the A/F. Look at how much higher the boost level is (16 PSI, then moving down to 12) those numbers (boost and A/F) are pretty far away, it's not like the boost on this setup would be as low as 11 PSI, or the A/F would be as lean as 16 You can also tell by the way the line is drawn on the graph, The boost line will always Increase upwards, then fall off a bit, and the A/F will be underneath it. oh ya, no qustion is a stupid question

Impressive numbers for a Stg0 Shiv! Freak maybe?

What does the Stg 0 usually dyno on the DD?

Right around 200whp. So an extra 10% at the wheels is pretty surprising. Pleasantly surprising of course.
