Our prices
The basic fee for a complete cylinder head adjustment is 450 eurosper cylinder, for an aluminum cylinder head with four valves per cylinder.
The price may vary according to cylinder head material, number of valves, work required and different options available: phosphor bronze guides, copper-beryllium seats, titanium valves, DLC treatment, reinforced springs, mechanical tappets, etc.
Additional cleaning charges may apply if parts arrive excessively contaminated.
This price includes the following steps:
- Complete inspection of your cylinder head (flatness with a ground ruler, hot penetrant testing using contrast agents to detect micro-cracks)
- Micrometer control of guides
- Vacuum valve tightness test
- Complete cylinder head disassembly
- Checking spring rate on test bench
- Check camshafts for straightness and wear using a lever comparator
- Initial flow measurement in wind tunnel
- Conduit molding
- Calculate the ideal conduit to suit your needs
- Ultrasonic measurement of available material thickness around conduits
- Specific machining of valve seats, up to 5 angles
- Special valve machining
- Aerodynamic machining of ducts
- Specific conduit finishes
- Improved combustion chamber aerodynamics
- Multiple wind tunnel runs for confirmation
- Equalizing chamber volumes
- Volumetric ratio calculation
- Cylinder head gasket facing
- Wind tunnel final flow measurement
- Edit your cylinder head flow report
- Complete reassembly of your cylinder head
- And finally, packing and postal return of your parts
Your cylinder head will return to you ready for operation – Plug and Gas!
Sending the entire intake chain from the throttle valve is not compulsory, but is preferable for ideal preparation. Aerodynamic optimization can also be carried out if these elements prove to be flow-limiting.
