The Power Plus 764 Nozzle is the an excellent upgrade for most TDIs equipped with a mild to moderate turbo upgrade. It is also an effective upgrade on other VE TDI cars. .232mm orifice diameter.
The OEM and their suppliers must compromise quality and performance characteristics to meet production numbers. These limitations are compounded by the bean-counters in the corporate office always demanding lower cost.
The Fratelli Bosio Power Plus philosophy removes these artificial OEM limitations, by applying industry-leading technology to decades of injector nozzle manufacturing know-how.
Each Power Plus nozzle embodies thousands of hours of testing to achieve the most effective design, without compromise
+30 whp and +60lb-ft nozzle
The Power Plus 764 is recommended for TDIs with a mild to moderate turbo upgrade and ECU tuning.
The absolute best results will be obtained when used in conjunction with the Q Loader Flash Programmer and Kerma Tuning (see 'Chip Tuning and ECU Upgrades'), a VNT 17 or larger turbo, (see Turbos) an upgraded exhaust system, (please see our selection of downpipes and exhaust options) and upgraded air charge cooling. (see our front mount intercooler kits) Such a set up will support 150-210 WHP.

Flow Data: 154% Above Stock Flow
We flow tested and data logged complete sets of these generic "LA 150P 502" aftermarket nozzles claiming to be on par with the PowerPlus 764 nozzle. The overall quality was on par with a $5 "Made in China" nozzle. The actual flow results were not surprising (to us anyway). We picked the highest flow nozzle of the batches we received and graphed the flow data. The flow variations were significant despite the claims that they were "flow matched" using a gun powder measuring tray. We understand that they flowed "3.5 grains" (marked on the injectors) using 25 strokes of their vintage hand-pump.
What we found using a certified nozzle flow bench was a typical variation to be in excess of 10% using ISO 4113 calibration fluid at 40C. Also, we found the actual flow to be far below the PowerPlus 764 in actual flow volume. This generic nozzle is actually more in line with the much lower flow range 520 nozzle despite having much larger holes bored into them. It's the quality of the nozzle, not the size that differentiates one nozzle from another!
Another attribute is the poor sealing characteristics of nozzles. The nozzles had dramatic leakage and failed every leak-down check we performed.
Add KermaTDI VW TDI turbo upgrades and TDI ECU or TDI Tuning upgrades with the Kerma Q Loader flash programmer and we can take the 90 Horsepower VW TDI to 135 , 150, or 175+ Horsepower. TDI performance with increased fuel economy, that is why KermaTDI is a leader in VW diesel performance .
