    • Billet Design Motorsports Stage 2 McLaren 570S Mustang dyno results - 573 whp

      Billet Design Motorsports does some solid McLaren tuning and their Stage 3 McLaren 570S recently ran 9.7 @ 144.3 in the 1/4 mile with hybrid turbos. This is a Stage 2 car though which just means bolt on modifications (tune + exhaust) on 93 octane pump gas.


      It is making 573 wheel horsepower on a Mustang dyno:


      They estimate this is roughly 640 whp on a Dynojet and that is probably a solid estimate.

      It's good to have multiple graphs from multiple machines for contextual purposes although a baseline here would be nice.

      Perhaps @Juan@BigBoost-Billet can provide it.
