BRZ stock power for 2017

What does the BRZ stock power output look like?

The Subaru BRZ is new and improved for the 2017 model year. In addition to other enhancements, power increases are at the top of the list. Subaru claims to have increased the BRZ stock power by 5 horsepower and 5 lb-ft of torque. This brings the total horsepower output to 205hp and total torque output to 156lb-ft. Are these new BRZ stock power claims true? Well, I took my 2017 Subaru BRZ to the dyno and had it compared against my old 2013 Scion FRS. Both cars were bone stock when they hit the dyno. Although, the timelines were different as the FRS was on the dyno a year prior. However, the numbers and dyno graph don’t lie, take a look!

FRS horsepower post upgrades

Post upgrade FRS horsepower!

Now that I have all of my engine modifications installed, it is time to hit the dyno. Our goal on the dyno is to figure out the FRS horsepower after the upgrades. The addition of intake, headers, exhaust, and a tune should show decent improvements over the FRS stock dyno power numbers. Being that these are small boxer engines, I am not expecting miracles. Increasing horsepower and torque in the mid-range would be ideal. Turbocharging or supercharging would be the next step for even more power. However, for my autocrossing needs, these engine bolt-ons are sufficient. I also have to stay within the rules of the SCCA STX class with my upgrades.

 

Scion FRS stock power

My car on the dyno to get the FRS stock power output!

People love to modify their FRS’s with engine upgrades and the like. But how to you know the benefits of your upgrades if you do not know the FRS stock power output? The first thing I did before installing any upgrades on my FRS, was to get the car on the dyno to see how much power it made. This way, I can tell exactly what kind of benefits my future upgrades will provide. In addition, this gives you a “bang for you buck” analysis as well. Is it really worth spending $1000 on an exhaust system? Or, does the $500 exhaust system provide the same benefit?
