This is the interesting part: Carl T. is the owner of the car, and also the owner of general repair shop in Saint Paul, MN. He has extensive automotive background, particularly with the LS series GM motors and is widely known as a expert tuner for that platform. He chose MAPerformance as the go-to tuner due to our reliable history with import cars and Subaru in general. Carl is an avid auto-crosser and has participated in many events across the Midwest, including Road America, Mid America, and MAP's Proving Grounds. Carl needed this turbo to be fast spooling and capable of producing top-end power over 6400RPM. That is exactly what he got. The car pulls hard through every gear and sounds insane to boot! According to our in-house tuner Jordan, "this is the best kit I have ever tuned on a Subaru". He testifies the transient response on this car is amazing, and it's what sets this STi apart from the others. Carl agrees, saying "the transient throttle response is completely opposite to the FP Red ... where the FP would lag, this turbo keeps spool and is explosive almost immediately. I'd recommend MAP's STi rotated mount turbo kit to anyone looking for some extra power". Check out this graph, and you'll agree! We did a few pulls here on our Dyno at both 26psi and 30psi, both running a E85 winter mixture. While we were impressed with the numbers we got at 26psi, Carl had us turn up the boost a little bit to really test the limits. 30psi was outstanding as well!
26psi - 488whp/454wtq 30psi - 530whp/468wtq Here is the video of the car on the dyno. Check it out!
