Planning a larger turbo upgrade.

Planning a larger turbo upgrade.

A turbo failure after tuning needs investigation; its timing alone does not establish the cause. Existing wear, mileage, servicing, the calibration and the fitted hardware all need to be considered.

We provide a written risk sheet before tuning and use road and dyno logging, particularly on Stage 3 and larger builds. Testing can help identify problems, but a calibration cannot repair worn bearings, rings or a damaged turbo.

Larger turbos also change how a car drives. A setup that works well on a drag car may have too much lag for a daily driver. Fuel supply, injectors, intercooler, clutch and engine condition need to match the intended use.

Discuss the whole build before buying parts, including second-hand components. Allow time for development and a budget for repairs; an unusual combination may need considerably more than half a day on the dyno.
