Titanium Head Studs
it seems that ARP have introduced Head studs manufactured from Titanium which seems like an interetsing idea.
TITANIUM: ARP now offers special order fasteners made of an alloy (Ti6Al-4V) that is specially heat-treated (a process developed by ARP's own Russ Sherman) and provides superior strength to other titanium alloys employed in racing and aerospace. The material has a nominal tensile strength of 180,000 psi, and is very corrosion resistant. The main advantage of titanium, of course, is its weight – which is about 40% lighter than a comparable fastener made of steel. Head studs and accessory bolts are ideal applications for this lightweight material.
Obviously the modulus is a bit lower and there could be some bi-metallic corrosion issues if the studs weren't coated with a PVD layer such as carbide or nitride but has anyone tried or were they used on the 917 or other factory engines?
