Dnk Posted January 24, 2012 Share Posted January 24, 2012 They are billet aluminium. Not weighed them but should imagine they are light Do you know what grade of aluminium alloy they are Rob ? just me being a typically anal engineer and like to know these things Link to comment Share on other sites More sharing options...

Rob_Mitchell Posted January 24, 2012 Author Share Posted January 24, 2012 the grade of ali is 6082, its a machining grade ali. weights are as follows stock alternator pulley = 273g our pulley= 91g stock water pump= 455g our pulley= 182g or 163g (depends on design) Link to comment Share on other sites More sharing options...

Im an enginnering geek i'll have you know The figures i posted dramatically show the differance of the same grade of aluminium alloy after a bit of tempering so you really do need to know the exact spec of the material your using, Robs is spot on and also very good for anodising Without guys like me you'd still be walking or riding a horse Edited January 24, 2012 by Dnk (see edit history) Link to comment Share on other sites More sharing options...

Nothing but the best for the under bonnet treats. I should have a finished set by next week i hope but im waiting for the power steering shaft to arrive first.

Bossco Posted January 24, 2012 Share Posted January 24, 2012 (edited) I'll be intrested in a power steering pulley mate. You should have said you were this close to having them finished and I wouldnt have asked you to spend all the time on my stock pulley.
