What does this process really do to Metal ? I remember having some Con rods done years ago on a race engine but can's remember if anything benefited from it.
yes it works, very well, you can do cranks but you will to get them straightened after or checked.
F1 & them big v8 things are all cryo treated then shot peened.
shot peening works the surface metal and compacts the top layer giving a composite stress, so its alot harder & less prone to small cracks thats what leads to failure.
it's a 50% increase in strength with no adverse affects and no brittleness, it also creates better oil lubrication and cooler running of metals.
for example a high torque mini puts high stress on gears then cracks form and it rips the gears apart.
the spoke to alot of company's they all do the same thing.
wrx gears are now shot peened from factory as the older Gbox's were crap.
it's not alot of money either but you must cryo then shot peen and getting the gears dressed in that order.
ill let you know how i go as my car will be back together in about 2 weeks and hopefully the sc12 running in another 4 weeks.
i have now had Cryogenic treated
gears/baulk rings/syncro hubs
/pins/planet gears/output shafts
drop gears
next is to have the gears shot peened and dressed.
you can do it to anything even low powered mini's, it makes it last alot longer then normal, I believe in it & the proof is out there fingers crossed my Gbox lasts & lasts & lasts
