Passion as the starting point
The engines and cars we care about are rarely ordinary. They have a history, a personality, and often a particular reason to exist.
At Waynholl, that passion drives us to give every detail the same attention we would demand for our own engines.
So every project begins with a precise understanding of the need, the objectives and the constraints of whoever entrusts it to us.
Understand the mechanics. Respect the machine. Attend to every detail.
i
Understand the mechanics
The engine’s condition, history and use guide the technical choices.
ii
Respect the machine
Preserve its character, keep what can be kept and replace what needs replacing.
iii
Attend to every detail
The standard we hold for our own engines, applied without exception.

Understand, to answer better
A mechanical project is not a list of operations. It answers a use, objectives and constraints that belong to it alone.
Our role is first to understand those needs, then define a technical answer that fits — seeking the best balance between quality, cost and lead time.
Our expertise then lets us step in at the level the project actually calls for: from a complete engine rebuild through to a single machining operation.
Not simply deliver. Understand, propose, then deliver.

Your engine taken on end to end
Measuring, machining, grinding, balancing and assembly — every operation on your engine carried out in one workshop.
Machining, grinding, balancing and welding — the workshop's own machines, and a written record at each pass.
Workshop
Machines, light and swarf. A few frames from the workshop in Saint-Germain-de-la-Grange.
Projects made to measure
Particular attention to detail, to meet the specific needs of each project — whether it comes from a private owner or a professional.
Complete rebuild
The engine arrived seized, a valve stuck in its guide after years standing still. The owner wanted to use it for long journeys, so we chose a full top- and bottom-end restoration with electronic ignition fitted. Private owner · Road use Naturally aspirated and turbo engines — Porsche headsValve guides and seats replaced
Full head overhaul after identifying the worn parts to replace. Some seats could be kept where wear had not gone too deep. The heads were assembled with a new set of guides and new valves. Professional · Head overhaul R8 Gordini head — René Bonnet Djet coupéCasting crack welded, guides and seats replaced
This head was new, yet carried a casting crack. We closed it by welding, then fitted the head with its valve guides and seats. Repair · Rare part savedPrecision for the Passion · Passion for Performance
