IT IS NOT BOOSTED FOLKS!

The new 3.9L V6 is a NA VVT pushrod engine producing 240-245HP/245TQ. It was designed to make a flat torque curve verses peak power & is used in several mid sized GM platforms. (mainly behind a slushbox) It has 90% of peak torque available from 1800rpm to redline. That's saying something for how it's tuned.

It's "spec'd" at roughly:
15.7 @ 95 in the 3800lb Impala (slushbox)
15.5 @ 96 in the 3600lb Malibu Maxx (slush)
15.3 @ 96 in the 3400lb Malibu (slush)
15.4 @ 95 in the 3400lb G6 (slush)
15.0 @ 97 in the 3300lb G6 (6-spd)

It's also used in many of GM's SUVs.

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
