...the thread has gone all cold
...remember a T4 at 1bar will make more power than a T34 at 1bar..why?...MORE AIRFLOW...and if we dont open the ports we get SURGE past a certain pressure...so strap a GT42 on and it should spin up at around 5.5k i reckon 1bar from that is equivilant to 2bar airflow on a T4
...so surge city on std ports...learn from me folk..i wont blind you with big fancy words.
