HEHEHE; stock OEM/Audi lifters: 65.7 grams each...
New lightweight lifters:
48.3 grams each. Net difference; 26.5% lighter each. I'm
LOVIN it!!
Ounces:
Stock: 2.32 ozs. each
Lightweight: 1.7 ozs. each
If my math is correct thats a one pound
parasitic/frictional weight loss per crank revolution for valve train figured
at 2:1 cam-to-crank ratio.
That number for lifters alone is better than I hoped for with valves,
retainers, lifters and keepers combined. If I'm dreaming no one pinch me just
yet ok?
Probably should have said "double perceptible benefit"...
because I "think" these should
very closely parallel the perceived net affect of the AAH cam conversion or
effectively double the perceived improvement if done with the AAH conversion. I
don't anticipate these being a very subtle or barely perceptable
modification. I think RPM's will pull dramatically
sooner/harder/faster even if everything else remains stock. They'll work on
AAH/AFC engine codes with no other modifications and in conjunction with and/or
as an enhancement to any/all valve train or cam upgrades. Right-outta-the-box-plug-n-play installation with no modification
necessary.
But hey whatta I know!?! They could also be crappola. For right now all I have is lightweight lifters.
Makes no statement whatsoever as to how well they'll work... it's possible they
are crap, I'll be the first to admit it. But they may be the greatest thing
since sliced bread too. Until someone plugs a set in and goes tooling down the
road they must remain, at least for now, just "lightweight lifters"
and nothing more.
I've had this feeling before on such things as airbox
velocity stacks, bored MAF housings, bored throttle bodies with integrated
velocity stacks, 3" silicone hose kits, recovery sleeves and even cheap-o
AAH cams to replace our anemic AFC cams. Time will tell if these get placed on
that list or if they'll go the way of my moms salmon croquettes.
