Jesse and the red dragon are away on annual leave to the VIC high country for a few weeks. At a glance, we were very concerned to see diesel internal version of a very similar looking TD42 Turbo Nissan Patrol. Happy with the outcome that Jesse is still having a ball at the VIC high country and a good laugh we got onto the tuning process.
Lack of bottom end power until 1800rpm- booked in for a tune to resolve.
Power Curve Performance TD42 Turbo Tune
After an initial check run, the customer concern of lack of bottom end power was easily identifiable. Dyno dynamics dyno reflected the afr 15-1 and no boost until the 1800rpm indicating an issue of some kind. Proceeding to make the initial adjustments to the pump resulted in no change as would be expected. TD42 Turbo Nissan Patrol with all components working well these adjustments will begin to see the 4×4 start to respond and improve. No response or results indicate something further at fault. At this point, depending on the situation and vehicle we will investigate further. Alternatively, if we need to start doing serious investigation such as pulling things apart to a further degree than the price you have agreed to the customer will receive a call from the mechanic in charge.
Outcome TD42 Turbo
On investigation of the TD42 Turbo there is clear indication that the turbocharger has a very badly sandblasted compressor wheel. This has caused the result in the lazy boost curve and low power as per the customers’ concern. Outcome for the customer will be a new turbo. The customer is now working with our team with the outcome and a new turbo will be sourced and installed. TD42 Turbo Nissan Patrol will be back on the dyno in the not to distant future to tune all components of the TD42 for a great every day and weekend 4×4.
