my 5KTQdoes 0-60 in a little under 7 sec. I have a IA stage II box, K&N filter and run 14.5psi of boost. To get these number seems abusive, 3500-4000rpm and side slipping the clutch. Have done this about a dozen times with times running from 6.56sec to 7.15 sec. The times were taken off a casio wrist watch held in my right hand so the accuracy is questionable. Jim
