One workshop, one family

The whole combination, under one roof

The best results come from parts that are chosen to work together. Because we build the engine, spec the cam, fit the blower and tune the car ourselves, nothing gets lost between different shops, and one family takes responsibility for the finished result.

Not sure where to start? Tell us what you drive, what fuel you want to run and what you want the car to do, and we will give you a straight answer.

The workshop

Equipment we rely on

As Sam puts it: “Whatever equipment I need to do a job, I don't care what it costs, I'll buy it.”

  • Engine dyno

    A purpose-built engine dyno room for running in, testing and tuning engines before they are installed.

  • Hub dyno

    Bolts to the hubs for accurate, repeatable power at the wheels with no tyre slip.

  • Flow bench

    Used on cylinder head work to measure and prove airflow.

  • Spintron

    Spins the valve train with an electric motor to check stability at high rpm.

  • Cam checker

    Every camshaft is checked before it goes into an engine.

  • Sunnen bore gauge

    Precision measurement for cylinder bores and clearances.

Do it right, do it once
