2015 WRX Project Northstar – Stage 2+ Dyno Graph

So it’s been a long winter and there hasn’t really been any updates to the car over the winter. It ran great through the winter and the few days of snow we had I took it out for some fun in the snow. So with spring upon us it was time to make some upgrades to the car for the upcoming track season. But before we jump into that I wanted to get around to posting the dyno graph from last year of the final stage 2 set-up that I’ve been running. As previously mentioned going from catless with stock cat-back to catted with aftermarket cat-back gained a little power but a huge amount. This is probably balanced out by the cat being a restriction but the cat-back being less of a restriction compared to the stock cat-back. So below is the dyno graph which shows the WRX made 285WHP and just under 330WTQ.

The car has been on this same tune since it was done and I haven’t had a chance to check the carbon build up on the intake ports which i’m hoping isn’t too bad and hasn’t hurt power too much.  In the coming weeks I am considering changing to the catless j-pipe again, adding the Killer B TMIC and possibly methanol injection.  We’ll update the dyno at that time for the upgrades and see what happens.

  • Hey guys, your project update blogs are awesome and the WRX is looking great. Is the WRX still on the stock rear brakes with the BBK up front or have you changed anything?

      We’ll be updating that very soon but as of now the car has StopTech rear brakes similar to an STi brembo, uses the same pad in fact.

  • Very nice results! I’ve also heard great things about the Killer B TMIC.

    Looking forward to future results for Project Northstar!
