Default 2013 Subaru XT Auto - Customer Build at Black Market Racing



We had a customer bring us in his 2013 Forester XT turbo automatic last week looking to get some more power out of it. His goal for the first round of mods is to exceed stock STI awhp figures.


The Power plan:
Cobb Accessport
Cobb Air Intake
Perrin Up-pipe
Invidia Off Road Downpipe
Perrin dual Cat Back

The Appearance/Suspension Plan:
ISC Coilovers
OEM Subaru Front Underspoiler

We immediately installed the Cobb AP for him while we waited for the rest of the parts to arrive and strapped the car on the dyno to get some baseline power #s. She put down 191awhp and 208wtq before the AP install, afterwards it picked up 15whp and 22lbs wtq! Not bad at all for a base map! He could not believe the difference it made with such a small change already, I can't wait to see what he thinks later today!

The parts arrived yesterday and we are in the process of installing all the power mods today and then doing a true custom dyno tune after it is all said and done to see where we end up. I will keep this thread updated as we go along.

The car on the dyno last week:


Factory exhaust removed and compared to the parts being installed:


More pictures and videos to come in a few hours!

Unfortunately we had a malfunction on the dyno that prevented us from seeing torque numbers so we will need to put it back on the dyno when its back to have the suspension and front bumper cover installed but so far shes up to 248awhp! Not bad, almost a 60whp gain over factory. We were really hoping to see closer to 270whp but the stock turbo just can't keep up. Even though we were trying to command at redline it was tapering down to 8psi. It sounds like a turbo swap is in the future but for now the owner is currently enjoying the new found power he has.

Coilovers will get installed next week and the owner is already ready for more power via a turbo swap so that will be in the works next.

The sport lower front bumper cover got installed this morning but I did not have a chance to snap any photos. I will post a photo update after the coilovers go in.
