RPM's For Performance

[mfm22]

I'm wondering what would be the RPM range that allows engine to come alive without approaching red line

2002 986 5 spd [ not S]

I just had some pro active work done [ IMS , RMS , Clutch , flywheel ] and would like to
start driving car a bit more vigorously not racing just letting it go occasionally

I have been shifting mostly between 3- 4k rpm's Have gone into 5k and felt more power
1st gear won't need too much higher than 3 k [ thats just my feel for it ]
2-5 would be more flexible rev wise
