You want more power? Not a problem.
Vitesse now offers the “SLEDGEHAMMER” cylinder head. We modify the factory cylinder head, fit it with larger valves, port it and flow it.
 Flow numbers are important, however real wheel horsepower is what matters the most. Vitesse has done a before and after tests. When the “sledgehammer” head was used on a 2.5L 951 engine, running our Stage 3 kit. We saw as much as 30rwhp gain.
We offer products that perform.
