It was mounted correctly. The drive wheels are supposed to be on top (and slightly to the front) of the roller.

The straps at the rear of the car keep the car on the roller.

I bet tuning can improve the 3500-4500 torque dip and the torque drop off at high RPM.

NYC BRZ · 04-05-2012, 05:04 PM

Is anyone else concerned with the 20lbft dip in torque from 3k-4.5k? Why would it do that? Direct injection issues?

I ignored as well. Wasn't even sure how to approach that.

either that or variable cam timing issues. Not sure if this engine has a variable acoustic intake, but that would be another culprit.

If you want some reading material, there is some good info and speculation in this thread about it.

Hmm. Runs pig rich up top.

That 20 wtq drop has got to go. That's just awful.

I believe that it's typical for a Subaru to have that dip. I remember reading about it NASIOC. I don't know why though. Sorry.

Dyno numbers are within acceptable range to the FRS numbers but unlike the rumor they are not more than the FRS. Odd.

hey not bad numbers....I also was thinking 170hp...but its all good...

engee · 04-05-2012, 05:30 PM

I wonder what Cobb will be able to pull out of this engine by tuning it. Definitely curious to see what results they can yield.
