Numerical turbulence with hyperviscosity is studied and compared with directsimulations using ordinary viscosity and data from wind tunnel experiments. Itis shown that the inertial range scaling is similar in all three cases.Furthermore, the bottleneck effect is approximately equally broad (about oneorder of magnitude) in these cases and only its height is increased in thehyperviscous case--presumably as a consequence of the steeper decent of thespectrum in the hyperviscous subrange. The mean normalized dissipation rate isfound to be in agreement with both wind tunnel experiments and directsimulations. The structure function exponents agree with the She-Leveque model.Decaying turbulence with hyperviscosity still gives the usual t^{-1.25} decaylaw for the kinetic energy, and also the bottleneck effect is still present andabout equally strong.Comment: Final version (7 pages
