Actually the turbo setup from the starion has a wonderful powerband for offroading, with full boost coming in at around 2800 rpm...


Well, stock, I agree with you. It has almost the exact same peaks as the V6 does! However, once you *modify* it, you are going to shift the HP peak higher and higher, running the RPM's up to take advantage of the raised boost pressure. At that point, I'd prefer a weaker V6 with a less peaky powerband.



No.... Turning up the boost does not shift the basic power band. That is determined by the profile of the cam, port size, turbo matching.... ect.

Putting in a turbo that does not spool up as soon (larger unit) will shift when boost comes in.

A longer duration cam will shift the rpm band up.

There is a small shift since the rpm where 12 psi is availible is ever so slightly higher or has a bit longer delay than 10 psi.

In my experiance its a very small diff...
