Camshafts, Repairs And Parts

Reground Camshafts

The principle behind camshafts is simple: if you can open a valve further for longer, you can get more air/fuel mixture into your engine. If you can burn all of this and exhaust the waste gases (through your exhaust valve being open further, for longer), you get more torque, which with revs, means power! Alas, reality dictates that bolting an outrageous camshaft into a standard engine will simply result in very poor running, so we've categorised our camshafts as below. Anything beyond RBC4 and RBC12 is not recommended for use with a completely standard engine. It should also be noted that uprated camshafts are not compatible with the standard injection system, requiring use of either carburettors or a mappable system.

Reshaped valves improve an engines breathing, making the most of your gas-flow work on the cylinder head. The stainless type are made to our specification by the country's leading manufacturer from a considerably stronger, more hard-wearing material.
Uprated valve springs are recommended for all camshaft profiles, but essential for RBC8 and RBC16. Billet camshafts will need the full race springs, held in place by our performance collets.

Stainless Valves

We now have a range of race valves for the 6 cylinder and V12 engines. Lightweight design with tulip-shaped heads designed for optimal gas flow with a narrow seat, these valves are produced from 214 stainless and tuftrided for excellent wear properties. We now offer oversize inlet valves, designed to use a throated out standard valve seat, in addition to our conventional big valves.
