Project Evo X GSR – Keeping Cool with Greddy and Koyo

,

 
When test fitting the bumper fascia back in place we noticed that one of the internal ribs hit the intercooler core a little.
 
We quickly used an angle grinder with a sanding disk to make a little room.  This was super easy.
 
 Everything all buttoned up and ready to go!  The fit and finish of everything was really good.
 
To see if we could extract more power from our stock turbo with a better intercooler, we asked Naji Dahi of Looney Tuning for some help.  Here Naji is hooking up his Innovate wide band air fuel ratio sensor.
 
Everything taped down to avoid wires flapping in the wind.
 
Naji tried turning up the boost and advancing the spark after correcting the air fuel ratio.  Despite the car being very resistant to knock with the big intercooler, we were not able to get more power.  This indicates that we have maxed out the stock turbo’s capabilities.  Stay tuned, we will soon address this with a bigger bolt in turbo and all of the various odds and ends to support more airflow and more power.
With the big intercooler, radiator and hard pipes in place we resumed our quest for more power by turning up the boost and retuning things with ECU flash.  Although we had no knock to speak of, even with more aggressive tuning we were unable to extract any more power from of the stock turbo.
We feel that the Greddy intercooler needs a bigger turbo and more airflow to prove itself effective.  Even with the efficient intercooler reducing our intake temps, resulting in no knock count, we could not make more power.
Stay tuned, in our next installment we will test some Cosworth cams to see if perhaps a little more flow through the engine can help us eke out a bit more power from our Mitsubishi’s stock turbo.
