LRM2hot's Lancer Evolution IX is clearly one of the nicest looking rally red Evo's within the state of Florida. It definitely has the power to back up its looks too, thanks to continued support over the years from TTP-Engineering and Orlando, Florida. Sporting the factory BBS lightweight forged aluminum wheels with a custom gloss diamond metallic black paint job, wrapped in 255 profile tires and sitting on Tein S-Tech lowering springs, it sure gives it an aggressive stance.
Into the engine bay, this Lancer evolution is configured with an INJEN intake system of the polished aluminum variety. Outfitted with a forced performance FP black turbocharger in Journal bearing form, this unit is responsible for supplying the compressed air forcefully into the motor. Before this boost reaches the engine. However, it is first cooled off with a ETS 4 inch front mount intercooler.
Fuel is supplied through a TTP-Engineering twin fuel pump system to low impedance 1250cc fuel injectors. The factory Evo nine metal blow off valve has been modified with additional spring pressure to be able to withstand the higher boost levels associated with this car's high performance output.
Once the exhaust gases pass through the turbine, they exit through a TTP-Engineering tubular oxygen sensor housing, before exiting out of a 3 inch mandrel bent turbo-back exhaust system.
With a switch to speed density tuning this time around, the mass air sensor was omitted in favor of and Omnipower 4 bar manifold absolute pressure sensor. With this sensor, and custom ECU tuning by Pro tuner Scott Davis, the factory ECU is able to understand how much air is being consumed by the engine and the set up can be configured based on a pressure algorithm versus a Karman vortex reading from them mass air sensor, as it does in stock form. Speaking of pressure, the boost pressure is regulated by a Pierberg 3-port electronic control solenoid custom mapped by duty cycle and individual gear by Scott Davis.
The result? And impressive 404 wheel horsepower on 93 octane alone. Power levels were limited at this level on pump gas due to the customer's request for this specific 93 octane map to be able to be run hard for long periods of time at Sebring International Raceway in Florida with the Chin Motorsports group. We obliged. As with 99,000 miles on the odometer, our primary objectives were reliability, safety and mapping suitable for these hard running circuit events.
With the more conservative road race map out of the way, our client also wanted a more aggressive "kill mode" for use in town on E85 alternative ethanol fuel. We were able to provide at about the same boost level an additional 103 wheel horsepower at a mere 27 psi with our custom ECU programming.
In contrast, at 36 psi on our old Mustang dyno this vehicle put down 488 wheel hp, but as we have been using the Dynojet 424X over the past two years, at a mere 27 psi this car did 507 wheel horsepower. So for whatever competitor that was spreading lies that are Mustang dyno read high or was mis-calibrated to overinflate dyno numbers did so maliciously as there is clearly huge difference from 488hp@36psi and 507@27psi on the Dynojet. The vehicle was making so much power that such little boost that we decided just to leave it alone once we hit 500+ on the stock engine that could...
