guy says he is overboosting 22+ psi and motor is knocking.. So what kinda whp does a 20g td06 upgrade give a 06 sti usually? I read somewhere 350whp-500whp depending... Maybe the question i should be asking is, with top mount still, how much whp will it limit him to?
He could probly get close to 400whp with stock top mount, and maybe meth external gate and full exhaust.
I was there, and that STI is one hell of a quick sti. I missed the earlier posts on here, but the way STI was moving (quick spool, and power) it has to be a tod06 20g boosting to 25psi+ and i won't be surprised if Meth is in play (pretty sure it was). tdO6 20g+24-26psi+meth = 420-440whp.....and it sure looked like he was putting that much down.
