When the .21-7 hit the dyno it produced some pretty weak numbers as its track performance would indicate...... All in all for the $ the 21-7 is a pretty big disappointment and I would buy 2 Picco's before 1 of these Novas.. Also my C6 just ate its main bearing, does the RB's also use the low grade bearings ? my buddy dynoed a Nova 421 and it stomps all over the 21-7 from bottom to top, so badly its almost a joke....... Why would Nova de-tune their motors so badly ? i mean the 21-7 is terrible really when you consider its price....
