Not trying to troll you but... why call it a Porsche killer build? Sounds like you are trying to build a dragster to race a car that is in a completely different class. Porsches are known for handling, not speed. Hell, even as a 911 owner, I see those videos of the 1200hp 911 Turbo builds and can't figure out how they are still so damn slow! lol. Go find a Hellcat to beat up on.
Anyhow, good luck with your build and stay safe.
