Well my bud just traded in his S4 twin turbo for a C6 so a couple of Saturdays ago about 5 of us went out to do some highway pulls.

I ended up running a gt35 mr2 that has a lot of time and money into it and a turboed integra GSR that has JDM Type R everywhere on it with the JDM front end...this thing is the nicest honda around here. Well we went from a 40mph roll and the MR2 instantly pulled on both me and the teg while i got a quick jump on the teg, he slowly crept past me until i shut down at about 140mph. I thinks he's boosting around 17psi and i'm not sure what he has done for internals.

Then racing the c6, i told him to honk it but sitting at 4500rpms in the thrid brake boosting, i could hardly hear him honk so i jumped a bit but quickly got out of it so i only had a half car lead. Once i saw his front lift i got back into it and slowly pulled until about 130mph. He ended up right behind my back bumper.

Mods in sig.
I pulled off a 12.6 at 112mph doing a VERY conservative run.
