FWIW I made the following power with TFS TW's and a small cam (.480/.480 220,226):
Max RWHP: 290@5300RPM
Max RWTQ: 312@4500RPM
I was actually surprised at how power was dropping off pretty hard after 5500-5600 rpm. I was always told to keep the shifts higher (~5900, etc.) but a little lower on the shift points seems to be where my car performs best in the 1/4.
