Stock IHI VF35 Turbo vs Aftermarket TD05-20G - Speedo Time Comparison with Datalogs :: Subaru STi

You can see here an acceleration comparison between the stock IHI VF35 turbo and the aftermarket china TD05-20G turbo. I recorded the speedo and measure the time over the videoframes. Not the most accurate measurement but you get the idea. Overall the TD05-20G combined with the aftermarket exhaust system gives you more horsepower, less turbo lag compared to the stock setup. I did the following tests: 60-160 km/h 80-140 km/h 80-160 km/h 100-150 km/h 0-50 km/h 0-80 km/h 0-100 km/h 0-140 km/h Car Specs: - TD05-20G (China) - Maxspeed Turbo-Back Exhaust System with 200 Cell Cat - ECU is tuned (LC) Boost controlled with EVC Boost Controller IV ( bar in this video) - STi GeNome Defi gauges - AEM Wideband Failsafe AFR Gauge - Walbro 255 Fuel Pump (with stock injectors) - Unequal Length Header (original) - Stock EJ207 - 98 Octane Fuel Data Logging Parameters (logged with RomRaider from ECU): - Mass Airflow (Graph red) - Manif
