The 1,500 HP B58
Our shop car is our test lab. We're building a B58 toward 1,500 horsepower, chasing records and proving every part and calibration strategy before it goes on a customer car.
- Proven first: if it hasn't worked on our own builds, we don't sell it.
- Data-driven: every pull logged and reviewed.
- Follow along: build updates on Instagram and YouTube.
