Looking for answers and advice!
im struggling to find upgrades for my v8 panamera n/a I’ve read you can’t turbo chargers it or supercharge.but I’ve been told I can electric turbo charge it any thoughts or help I saw the torque amp twin turbos on Cletus McFarland YouTube and they said they work they made power boost etc. I know very little in these fields but I’d like to do something for a little more power or would it be better to diy buy a turbo brushless add a monster compressor to it and hookup the same way through the intake? Someone also told me to run the dual intakes into the front bumper for a cutout with a filter? So far I have the valvetronic exhaust system.I tried looking for aftermarket performance headers and delete the cats but no luck there either even to have a set of custom made headers I’d spend some money but I can’t find anything for this car. Any help I would be very grateful if you could educate wether it’s cams piston turbos
