Ken has been waiting a very long time to take his 2006 Lancer Evolution IX GSR to the next level. Standing the test of time, he is one of the original long time owners of his Lancer Evolution since it was showroom new. Along the way he took the time to respectfully modify it with the help of TTP Engineering, guiding the way. From our ACT HD-TTP version clutch model to the INJEN intake and intercooler pipes system, to a full turbo-back exhaust system with TTP tubular O2 housing and a K&N drop in filter. For tuning he had Scott@TTP take care of those duties and it proved to earn him low 12 sec to high 11 sec quarter mile times with just these minimal modifications.
This wasn't enough for him though. As an engineering student through most of the ownership of the car, he was able to adjorn his urges to dump money into the car before he graduated and landed his career job. Luckily for him, he did just that and could finally step it up to the next level of performance with TTP Engineering LLC.
On his most recent stages of upgrades, we had set him up with GSC beehive springs and S2 camshafts. In charge of supplying the air to the engine was a new ball bearing version of the Forced Performance Red turbo. More air needs to be met with more fuel so out came the stock 560cc injectors in favor of the FIC 1250 low impedance units. Knowing the limits of a single walbro in tank pump, we knew we needed to push more volume from the tank. We opted to add our inline pump upgrade system to his setup which bumped up volume 25-30% over the single in tank unit as measured by injector duty cycle % used to achieve XXX whp. Lastly, although not needed, Ken chose a Forge RS polished aluminum blow off valve to round out his set of mods.
Onto the tuning and into the 400's whp range we went without hesitation. On pump gas boost 26-27psi we were able to extract a respectable 417whp before moving onto the corn based ethanol alcohol fuel.
With the tank drained and new fuel added to the mix, we quickly ramped up power and torque while keeping boost relatively similar to the pump gas maps. At this horsepower and torque level and his odometer creeping up over the years Pro Tuner Scott Davis chose to cut peak torque on E85 by means of slightly more conservative boost ramp up and instead, allowed an extra 1-2 psi at the top end of the RPM band for a fast street and strip car that would remain reliable over time. Peak power on E85 and 27-29psi of boost reached 517whp with a torque curve liable to make the driver require two hands on the wheel when mashing the gas pedal.
