EVO 9 Performance Part Power Test
EVO 9 Tuning – Dyno Run 1 (Baseline)
Baseline dyno run revealed a healthy 261 bhp @ 7000rpm and 244.7lbs/ft @ 3500rpm at the wheels from its TD05HR-16G6C-10.5T turbo and its 4G63 motor with MIVEC variable valve timing.
EVO 9 Tuning Part Test – Dyno Run 2 (Flash Tune)
XS Engineering Reflash. Reflashing of the ECU allows the factory engine management to remain in control of the engine while using all the original sensors. This enables all the factory fail safes to remain. The Reflash uses a generic program for EVOs using a cat back exhaust system and an electronic boost controller although XS Engineering recommend taking your car to their premises to get a custom map made up.
After the Reflash peak power increased to 284.1bhp at the wheels @ 6750rpm and torque was up to 262lbs/ft @ 3500rpm with healthy gains throughout the rpm range.
EVO 9 Tuning Part Test – Dyno Run 3 (Exhaust)
Apexi GT Spec cat back exhaust system. A fully polished work of art. Seriously though, its said a lot but in this case the exhaust really does look to nice to put in underneath the car. The quality an even of the welding just shows how much time and thought Apexi have put into the design. The GT Spec system has one of the biggest bore pipes on the market at 95mm and one of the biggest tails at 4.5inches. The tail also come with a removable silencer when you want to keep the volume down. The resulting dyno graph show a general smoothing of both the torque and power curves with a resulting peak power output of 292bhp @ 6250rpm and torque up to 267.9lbs/ft @ 3500rpm.
EVO 9 Tuning Part Test – Dyno Run 4 (Electronic Boost Controller)
The HKS EVC VI comes from a long line of high quality HKS boost controllers. One of the biggest steps forwards with this new EVC VI is to program desired boost levels at specific RPM and throttle position points. The HKS EVC VI also has the ability to monitor up to two other sensor signals. The resulting dyno graph with the HKS boost controller is an even smoother graph for power and torque. Good gains from 3500rpm upwards with peak power raised to 299.7bhp @ 7000rpm and 270.5lbs/ft @ 3600rpm although peak power increases are largely due to an increase of 1.5 psi in max boost pressure.
Total gains of 32.6bhp & 25.8lbs/ft
