Contour Enthusiasts Group Archives Forums Modifications Forced Induction any supercharger??

You drove a supercharged focus that had a roots type blower. Very big difference between that and the centrifugal type blower we can get on the contour. The Turbo way outperforms the centrifugal supercharger in mid range to the top end.

So we really aren't comparing the same type of supercharger.
A roots type of blower on a V6 would be a different animal entirely than what we are used to though it wouldn't necessarily be better.

The GT28 on that focus had lack because it was sized big for big power. The GT28 on a 2.5L V6 (a bigger motor) would equal almost zero lag depending on the exhaust housing side. I'm talking boost from 1500rpm and probably full boost by 2000 rpm.
It would probably carry max boost to 5500 then fall on its face at higher rpms.

Zero lag at low rpm means more restrictive exhaust and less topend, effectively making it very similar in performance to a roots type blower but without as much drivetrain loss.

So you can't compare the things together. Trust us that the properly sized turbo for YOUR desired driving habits will be superior in most cases.
