The one that came with a HKS triple plate clutch, you know a clutch that holds over 1000Hp. Which is the first clue that the motor is built to the hill, meaning the compression is much better and maybe running 89mm piston's, which means could have head work done, because of the bigger ass turbo's that was or was supposed to run on that motor? Yea, that explains it......lol. But then again that guy said 379 or something like that at 14-15psi..........lol.
Hey just trying to find the explanation for the reasoning no one else is near that with so little in the last 10 years...lol. So is the mystery man on here with a profile so we can see just how many little mods he has as well ( like other guy ) ...lol :)
