I got my bigger turbo installed on Wednesday.
I was driving to my local weekly Subaru meet and there was a 1st gen Talon TSi on my ass. He gets in the left lane to pass me at WOT, and I punch it. I pull about a car on him in 3rd gear. We get the next light next to eachother. We smile to eachother and start pre-spooling at the red light. I get an ok launch at about 4.5k rpm's, but we come out in 1st gear almost neck and neck. In 2nd gear I put about a half a car on him, another carlength in 3rd, and kept pulling slowly from him. I shut down when I was at the top of 4th with him about 2.5 cars behind. We give thumbs-up and go on our ways. I think he may have the popular Evo3 16g turbo upgrade for the older DSM's. I have no idea how much horsepower they put down with those mods. It also sounded like he had an external wastegate or something like that.
SRT: after the Suby meet, I met up with my buddy who has a fast SRT-4. He has exhaust, intake, Stage1 chip, bigger intercooler, and supporting mods. We went from a 40mph roll, and he slowly walked me. We shut down when I was at the top of 4th and he was 2 carlengths ahead. He said that I was one of the fastest WRX's he has run. I went for a ride in it and it was all torque. It kept me pinned in my seat the entire time.
I am TurboXS stage4 with a Deadbolt Super16g turbo and using the stock intercooler for now.
I am only running about 17.5psi
My mods are in the link in my profile.
