Dyno Tune Thursday – Stock vs. COBB OTS Stage 2+ on a 2011 WRX

Below we have the third step that we did with our 2011 Subaru WRX Sedan after testing it Stage 1+.  We installed an Invidia catted Turboback exhaust and flashed the ECU with the COBB OTS Stage 2+ for AEM Intakes map.  The numbers were quite good although slightly higher in the top end due to boost creep experienced.  Next up we’ll have OnPoint custom tune the set-up and see how much ultimate power we can make.

Dyno Tune Thursday – Stock vs. Stage 1+ on a 2011 WRX

Here’s a back to back comparison dyno on a 2011 Subaru WRX showing the gains of it 100% stock and then after adding the AEM Intake and flashing the Stage 1+ map.  The turbo wasn’t reaching target boost and we didn’t have time to run the HWG map.  We would have expected to see another 20 WTQ and WHP gain if it was hitting target boost which is 17PSI tapering to 12PSI.  The gains down low are great for an intake and off the shelf map.

Dyno Tune Thursday – Stock vs. Stage 1 on a 2011 WRX

Here’s the start of a series of dyno tests we did to show the gains from stock to different stages on a 2011 Subaru WRX.  Here we have a back to back dyno showing stock vs. Stage 1 OTS.  While HP didn’t change much the torque increase was almost 30WTQ with a simple tune included with the AccessPORT.

Dyno Tune Thursday – Blouch DOM 3.0 + TMIC

Here’s an STi with a Blouch DOM 3.0 and built motor that was tuned a few years ago.  It had a TMIC so boost and power was kept lower to prevent heat soak on track.  With a FMIC we’d expect to see a bit over 400WHP on this set-up without heat soaking issues.

Dyno Tune Thursday – Does a stock cat-back restrict power on a turbo car?

Here we had the ability to compare, in relatively close succession, the same car dyno tuned with a 3″ downpipe and stock cat-back and then with a 3″ cat-back.  The results were quite surprising considering we had expected to see maybe 5HP difference at the most.  While this is only one test I believe it goes to show that any restriction in the exhaust of a turbo car will hurt power.  This car gained 15WHP and 15WTQ peak.

Dyno Tune Thursday – 2004 Subaru WRX with a VF48 Upgrade

Here we have a 2004 WRX that we upgraded with a VF48 from a 2009 STi, STi top mount and STi injectors.  This is a nice upgrade for the 2002-2007 WRX models as the stock TD04 turbo is very small and cannot produce much power.
