i went from a std 12kg flywheel to a lightweight billet 8kg flywheel and honestly noticed no real difference in acceleration,1/4 mile or fuel consumption..

so if there is a difference i think its 2/10's of f**k all...lol..

Haha true well I spoke to clarko from clarkos performance and he seems to think it makes a he'll of a difference but couldn't tell me how it would behave on the street.

True so for a street motor it's not worth removing 11-13 kgs off the rotating assembly? Sounds like heaps to me....but Im no pro that's for sure. Earlier in the thread someone wrote I should invest in scat rods for their weight and strength, there f**k all lighter then standard au rods, and I'm sure au rods can handle 200 or so kws. Maybe that's a waste of money aswell. I would have thought removing like 13 kgs all up would make a considerable amount of difference?? Like not just doing the flywheel, also the flywheel I'm looking at is alloy and claims to be 6.1kg.

I'm not worried about spending money on the crank and flywheel, or rods for that matter, otherwise were else should I spend 1500 dollars to extract more horsepower without forced induction??
Big learning curve for me thanks for any input

which intake manifold you running? i have heard of porting them to get more beans out of the motor?
the au rods on forced induction application will handle about 250+kw but they dont like it, troymans running 267kw on an unopened au motor

I wanna run a entirely new plenum, such as snort performance etc. Haven't fully looked into that yet. Otherwise I'll have a bbm or a log extrude honed, nearly costs as much as buying all new plenum! But I might loose to much torque with the plenum???

I'd say because its balanced and rotates from the center, a few kg makes no difference for an engine that is capable of propelling your 2000KG worth of vehicle at a high speed.

This idea of course is different for pistons, rods, valves etc because these items are moving up and down at a great speed so the weight will have an effect on maximum rotation speed.

Makes sense but I still fail to see how taking that much off will do sweet f all but I really don't know.

depends where the weight was taken from. weight taken from close to the center won't do much.
