is it going to make a difference to your engine build

the Scat cast cranks are quite good these days

but the forged are and would be much stronger

I read it on FACEBOOK so it must be true

Thanks Dave B. That is what I thought.
Yes it will make a difference to the build VW54.
I won't trust a cast crank when the engine will regularly see 6500rpm being a hillclimb car.
It will be in the up for sale section soon.
cheers

i think that this is pretty inconclusive. im not the metal expert but from what i know there is only one way to know for sure and its some sort of test that they do i forget the name of it. but i get the impression that it is virtually impossible to tell between modern casting and forging with these sorts of parts. i looked at one of these cranks years ago but was out of my price range. dont need one now though

haha thanks dude.

I cant really afford the crank at the moment... and my mechanic/engine builder has one ready to go on his shelf at home, just needs to be redrilles to 8 dowel, and matched to my lightened flywheel. its already been balanced and everything, so i should proabably pass, even though i don't know how much I'm paying him for that. :$

Thanks for the interest.
This crank is sold and I am now on the look out for a good 74mm forged counterweight crank.
