ACE Header Dyno Results

Did the ACE Header dyno results exceed expectations?

The ACE A-350 header is not cheap. But, like a lot of things, you get what you pay for. The ACE A-350 header is a top notch product that provides top notch gains as well. In the past, I have used the trusty RevWorks UEL header on my Scion FRS and my Subaru BRZ. This header provided decent power improvements, while also saving weight. After reading all of the hype on the ACE A-350 header, I finally gave in and bought one to test out. As part of the test, I first took a number of dyno pulls with my Subaru BRZ and the RevWorks UEL header. With those power numbers recorded, I could then install the ACE header and get the car re-tuned. Once that was done, I went back to the dyno to get the ACE header dyno results. The improvement in power was pretty shocking, actually. My latest video goes over all of the details and clearly shows where the ACE A-350 made more power over the previous RevWorks UEL setup.

After 2 years running my RevWorks un-equal length header, it is time for a change. My equal length ACE A-350 header from CounterSpaceGarage.com is ready to go in! The ACE header BRZ install process is just like any other header you can get for your BRZ, FRS, or 86. The design of the ACE A-350 header is slightly different which contributes to its unique performance. After installing the header, I also go over the basic tuning process for the ECUtek tuning platform. It won’t be long now and we will have the dyno numbers to compare this to previous BRZ dyno sessions!

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?
