RRE RalliArt Build -Baseline Testing and Tuning

[MikeW-RRE]

We had our car from South Coast Mitsubishi for a short two weeks to build. Our concept was to find the most bang for the buck mods, something the average guy would want to do while staying within a budget but get some real performance that he could feel.

The first thing we did was to do a baseline dyno test on it to see what we had to work with. What you see here is three back to back dyno pulls on our Dynapack DP6000 AWD dyno. I allowed coolant temperature to stabilize at 82 c between each run. Still you can see big variances between the runs as it warms up overall under the hood. The first run is red, second is green, last run is blue. A little heat in the motor is good. More.. well not too much. I called it a 210 hp average.





Stock factory boost is also very low. The little turbo is already building 5 psi at 2,000 rpm and hits peak boost before 3,000 rpm. But then it is a down hill rollercoaster ride from there on. It eventually falls to a low of 8 psi :-P




Air fuel ratio was predictably rich too. You can see in the second (green) run where for what ever reason the car was not so rich for a little bit around 5k. That is where the second run got is HP bump.
