F1 Pneumatic Valve Spring, a closer look

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Why a separate unit that bolts ONTO the head, rather than components that fit into a bore in the head casting (aka RA806E)?

Is this from a Cosworth TJ V10 with Beam Head?

It has a 'CA' part number so I assume its from a CA V8

Far lighter end result I would imagine. Also easier for micro drilling various passages too, not to mention that 'billet' alloy can be trusted fully in terms of air tightness in comparison to some cast areas. Also replaceable with ease.

does this system have some sort of tappet that the cam lobe rides on? Could you post a pic please. Also you're a hero for spending your money on these items to just tear apart and share with us plebs.

Hello there - it uses a dlc coated finger follower between valve stem tip and cam lobe - I'll post a pic of one tomorrow - have one here.
