The industry standard maximum average piston speed is 4000 ft/sec. Beyond this maximum average piston speed, the bottom end is likely to be suspect unless there have been significant modifications.
|
as an aside, that 4000ft is based on the material properties of the rods usually... in combination with the pistons weight and stroke etc...
fwiw, the S2000 motor has around 5000ft/sec, due to the lightweight piston design and excellent attention to detail with the design.. it's also designed within an inch of it's life 
funnily enough, F1 engines are also limited by these numbers and (at least used to) have around 5000, when everything else had 4000....
as for real life redline.. the higher you rev it, the shorter it's life, and the decrease in lifetime is larger than the increase in revs.... drive it hard, it's gonna die sooner...
as for sounding bad, no engine shuld be forced to keep going then, but components can fail before those revs....
just drive and see whre it breaks the first time  heh heh
