Hi Macca,G'day Mike, You want torque!!! , go see Ray at Turbo Engineering in Thomastown. He does his own units. Chits on the OFF the shelf stuff. And if you have a manual, ask him to do the boost control as well, No more riding the clutch. He did mine and it's amazing the difference....not just a small improvement...it's a MASSIVE improvement. On the Dyno torque is up from around 480Nm to 700Nm....Pulls like a train.
Can you post the results of your dyno run in whities thread?
