Setup right the VS1 will run around 50mph without a pipe.. Trust me when I tell you very seldom do you need to go faster in sport/stock or mod tunnel to be competitive in these classes.
The VS1 has the advantage of doing this on a sport/stock motor without the peakyness of a pipe or the weight and complexity.
Having said this.
The Villian S1 has won national championships in both the IMPBA and NAMBA with piped engines. Joe Monohan in NAMBA and myself in IMPBA. Its just not a great boat with a pipe.. but it’s a fantastic boat without.
