These are the typical results you can expect when modifying your 2015-2021 WRX. We started with a completely stock FA20 WRX and did 4 stages of modifications. We kept track of the results to show you the comparisons. All of these results are uncorrected numbers which are 20-25% lower than you would expect to see on a Dynojet dyno or our “Shootout” numbers. For more information on comparing dyno numbers check out our dyno page.
Our starting point was completely stock. With no tuning, no modifications, and with 91 octane fuel.
This vehicle made 180 HP and 210 FtLb TQ on our Dyno at 15psi tapering down to 10psi by redline. The factory rates these cars at 268 HP and 258 FtLb TQ at the crank.
Below you find the information of our findings along with dynographs for comparison. If you have any questions about building your 2015+ WRX , give us a call (763) 316-5882.
