Production Timeline
Specification Ordering
Your bespoke carbon intake starts by choosing your completely unique specification from thousands of different options.
Flange & Fitting Production
All Flanges & Fittings whether titanium or anodised aluminium are machined entirely in-house on our state-of-the-art, large format CNC using the finest 2 micron tooling.
Prepreg Carbon Lay-up
Production begins on the plenum body and runners where motorsport grade pre-preg carbon fibre is hand laid in-house into our own billet aluminium moulds. This is then pressure cured under extreme vacuum and temperature to form a high strength, lightweight structure.
Finishing
Once cured, the prepreg carbon is carefully hand finished with hours of fine sanding. Once levelled, the surface is professionally spray lacquered using several coats and then satin or tinting pigment is finalised in the last coat.
Trumpet Production
Your desired specification of trumpet length is additively produced using advanced Carbon Fibre 3D Printing. The plenum and trumpets are then adhered using ultra-high strength body adhesive.
Shipping
Your unique plenum is serialised, recorded and carefully packaged with an update provided on the shipping timeline.
