Extra kW

[5ivespeed]

i was going through my owners manual for a vr and it said that the 3.8L non irs had 130kW @ 4,800 RPM and the 3.8L irs had 132kW @ 4,800 RPM. why would independent rear suspension make a 2kW difference?

im thinking that either 1 is a 3.8 buick, and 1 the ecotec, or that the live-axle saps more power.

(ie more rotating mass)

different day they were stuck on the dyno. its 2kw, who cares.

[5ivespeed]

both buick. and it said it in the book

As said, its 2kw who cares. Im fair sure its wrong anyway and no I do not care if its an owners manual

irs gripping better on dyno ? better fuel in irs test car .. irs is lighter than a live diff ... the live axled car tester was a fatass ?

That's engine kw, flywheel power, it has nothing to do with the driveline and you'ld just be a typo or just a slight variation in two different tests. IRS takes roughly 6-8rwkw extra to power over a live axel (that's from a guy that swaped his engine from IRS car to a live axel and did nothing to it other than that between dyno runs)
