PD and VE Diesel Injector / Pump, Power Upgrades & Diesel Engine Tuning
VE and PD Injector nozzle replacement and calibration for diesel injection power upgrades. TDI Injection Pump repairs and power modifications.
We specialise in all aspects of PD diesel and TDI injector testing, repairs and upgrades. As we have the experiance, equipment and passion for PD and TDI injectors we can test, repair and upgrade your diesel injectors and TDI pumps.
There are two areas to consider when obtaining diesel injector power upgrades for your diesel injectors.
The quality and specification of the nozzle and the set up of the injector.
I always smile when I see the sale of nozzles to vehicle owners with instructions on how to fit them. A good sales ploy but from a technical aspect incorrect and potentially damaging to your vehicle. All nozzle replacements need the correct set up, pressure adjustment and calibration. It is better to have a cheaper nozzle fitted with the correct set up than to have an expensive nozzle fitted with no set up.
I agree that not all PD nozzles are created equal but with careful choice we can tailor the job to suit your budget, when available (stock problems with nozzle manufactures) we are able to offer a wide proven selection of nozzles for your diesel PD and VE injector upgrades.
With the availability of performance nozzles, bigger Pump Heads and our technical knowledge and capability we are able to build you a bespoke set of pump and injectors to best suit your engine build.
All diesel injection power upgrades go through the process of complete disassembly, ultra sonic cleaning, inspection, nozzle replacement, nozzle opening pressure (NOP) setting and then final calibration and flow test.
Years of experience in setting up of Bosch Two Stage VE TDI injectors for both the 1.9L and 2.5L engines have led to the establishment of a series of different parameters depending on application. Please remember that part numbers and part names associated with various nozzle manufacturers will only relate to the delivery of the individual nozzle. The final fuel flow is dependent on the set up of the unit as a whole. The flow rates below thus describe the flow of the injector, not the individual nozzle.
All flow rates have been tested using a Hartridge Two Stage Test Master and the flow rate is measured in “liters per minute” this is not the actual delivery but a measurement used to flow test the injector. All Bhp quoted will depend on engine condition and “engine build” in the case of modified systems.
Moderate Flow: flow rate of 1.45 to 1.55 L/min (litres per minute). A great injector used to revitalize your 1.9lt or 2.5lt TDI. No mods, no turbo’s, inter coolers or any remaps needed, just fit and enjoy. This set of injectors will improve response, torque and drivability with an increase in power of 20 to 30 Bhp, at a very affordable price. If you are thinking of getting your injectors reconditioned and don’t want to get involved in any other engine modifications this is the way to go.
Enhanced Flow: flow rate of 1.55 to 1.65 L/min, again with the 1.9lt and 2.5lt engine, just fit and expect an increase in power of approximately 35 Bhp and with a tune you should achieve about 50 Bhp. Great low down torque also noticeable.
High Flow: flow rate of 1.65 to 1.80 L/min these injectors are normally fitted as part of an engine tune sometimes with more efficient intercoolers, hybrid turbo’s and a few other minor modifications. Again with a tune you should see improvements in Bhp of about 100 Bhp
Super High Flow:flow rate of 1.90 to 2.10 L/min - even bigger turbo’s, more comprehensive engine modifications and a injector pump up-rate will increase power to about 250 – 300 Bhp
Extreme Flow: flow rate of 2.10 to 2.50 L/min this can only be used by an experienced engine tuner. A more comprehensive engine mod will be required with even bigger pump – uprate. Power achievable of 350 – 400 Bhp
