Power Pipe

Why
Test pipes or cat deletes are an express train to power, making them bang-for-the-buck standouts. Installation of a test pipe only requires a few bolts, but the ECU may need to be tweaked to run without firing a CEL, and/or falling into limp mode.

Verdict
The test-pipe fitted to our EVO eliminated a big restriction, resulting in better spool-up and a higher peak boost of 26 psi, versus 25.12 with the factory cat. On the rollers, the EVO responded with an impressive 327.59 hp, aided by a few ECU tweaks from O'Neal.

The power progression gleaned from the Dynojets of Drift-Office and English Racing show the EVO as a true boost junkie. Upon concluding our dyno tests, the EVO made 327 hp and 300 lb-ft of torque on the stock turbo, injectors and fuel pump. Adding 81 hp and 82 lb-ft of torque didn't faze the 4G63, as we saw an 82-percent duty cycle on the Mitsu's 560cc injectors...so there's definitely room for more power.

The key to making power in a 4G63 EVO is getting a good spike out of the turbo. The harder that initial moment of inertia, the more the turbo will carry higher boost levels throughout the rev range. Due to the conservative stock tune with 10.0:1 AFRs high in the powerband, aiming for more productive 12.3 to 12.5:1 A/F ratios nets big gains.

Tales Of The Tape

Final Verdict
Our array of penny-pinching power mods resulted in a total gain of 61.58 hp and a max gain of 81 hp at 7,100 rpm. Torque production checks in at 300.24 lb-ft-a 33 lb-ft gain-with a maximum gain of 82 lb-ft at 3,600 rpm.

An incredible amount of gain for less than a grand.

The Tuner
English Racing's Aaron O'Neal handled the majority of tuning, re-flashing the ECU at Drift-Office and ER's dyno in Camas, WA. The latest generation of Dynojets allows dyno pulls to be transferred from dyno to dyno via a .drf file.

Improved MPG?
The power potential of ECU flashing is awesome. But beyond the big dyno gains, our EVO laid down 27.08 mpg on the 200-mile trip from English Racing. This was performed on a car originally rated at 25-mpg highway, in stock trim.

Misc Mods
A Greddy strut tower bar, HKS oil cap and carbon fiber panels from Titek Innovations add visual spice to the 4G63, but the mission is to see what four mods and less than $1,000 will do the most to increase the EVO IX's power curve.
