So what's a crankshaft made out of if it's not steel? :-?

Humpy

cast iron presumably  :-/

Yep....

[unclelicklug]

Standard crank is generally machined from a cast iron blank, cheap to make and easy machining, not the best ultimate strength/lightness.
For more demanding applications a forged steel blank is used, the base metal has better strength characteristics (the forging process will also improve this) so the crank can potentially be lighter and/or lighter stronger.

Not sure if the standard-tuned Omegas engine actually needs this (not that it a bad thing to have mind you), it's more likely there in preparation for the higher-tuned versions that found their way into some Vectras....

There were no new higher tuned versions of the 3.2 in the Vectra...........

OK... I thought the VXRs used the same blocks as the 2.6/3.2 on their V6 2.8 Turbo versions?

Thats enough abuse about my driving for one week thanks!
i have driven both the 3.0 and 3.2 as old bill cars and i can only think of one engine failure, that was due to a 4th to 3rd change at about 115 during a pursuit (Not by me) it was quite spectacular with a big hole in the bottom of the engine.
The failures we had were almost always HBV's. the heads were sometimes changed but the mechainics blamed that on the endless hours of idling at the scenes of accidents.
and as for that thing that you call the rev limiter the technical name for its is the gear change indicator
i have owned a 3.2 manual old bill car for over 20 months now. in its day it was a slough traffic car its had many a staring role on roadwars, same engine and gearbox 140k at least 6 shades of white and now a veteran of 4 track days, the nurburg ring and a john o groats to lands end.
its been faultless
now thats a car!

Hate to know what he thinks about those scoda's made out of cake then

At the end of the day that has to be put down to damage caused by bad driving then and even a rev limiter will cut the engine based on a pre determined rev limit, not a gear change, which again would not happen on an auto.

A totally different new generation global engine with variable valve timing, turbo the lot.

You would eat it!

Vauxhalls VXR Vectra engine is a Saab 2.8 V6 Bi Turbo engine it started life in a saab and vauxhall have borrowed it off saab!

dont get me wrong that was bad driving that made the engine blow up the chap who did it may even admit to it!
