TPC Racing turbo kit 987.2 PDK Boxster S hits 507 rear wheel horsepower on a dynojet with meth injection and nitrous
The TPC Racing turbo kit is a very popular upgrade for the Boxster and Cayman. It's really the main forced induction kit out there and offers large gains. Well, for one owner the standard power wasn't enough. With just the TPC turbo kit the 987.2 Boxster will put out in the 415 horsepower to the wheel range. With meth injection, TPC was able to boost output into the 470 wheel horsepower range. Then on top of this a 40 shot of nitrous was added.
The result being 507 rear wheel horsepower from the 3.4 liter flat-6 engine. And that is on pump gas so clearly the meth injection is making quite a difference. 507 rear wheel horsepower is a huge increase from the factory ~26X wheel horsepower range.
