From the inception of the FT-86 concept car years ago, we all knew the platform was geared towards pleasing enthusiasts. The stiff chassis, factory made roll cage mounts, and high revving engine made it perfect for canyon carving and track days. However, most of us don’t take the twisty back roads on our commute to work or even spend many weekends at the track. The majority of seat time is spent daily commuting, and that’s where the biggest problem lies. Don’t get me wrong, the FRS and BRZ are a very engaging and fun daily driver, but there’s one issue that keeps it from being the great daily driver it’s capable of. That one issue is the infamous torque dip.
The torque dip
This annoying rpm range around 3,200 to 4,200 rpms, scoops out a noticeable chunk of useable torque. If you shift to early when overtaking someone, and you’ll land right in the torque dip. While your right foot searches for the power that isn’t available for another 1,000 rmps, the driver of the car you’re passing will be wondering why your car’s so under powered
The best way to solve this torque dip problem is with an unequal length header. Not only will this simple bolt on increase peak power by 14HP without any ecu tuning, but it’ll add 18ft lbs and 12HP in the infamous dip where it’s needed most. If you look at the dyno chart, you’ll see the new torque curve (represented by the green line) stays flat across the board, ensuring maximum torque at every speed.
Normally, a power bump like this would be too good to be true without a complicated tuning process, but our catted UEL header won’t send any check engine lights on a stock motor.
Every header takes nine hours to finish and is hand fabricated right here in the USA (Iowa to be exact). Also included is a lifetime warranty that protects against cracks or metal defects, as well as everything needed for installation, including Laffy Taffy.
The next batch of these headers will finish production towards the end of this month. So if you want the extra grunt that’s missing from your daily driver, claim yours before we run out again.
