I was wondering which mod would give me the best results all around!!!
No one attempted to answer this question. All around performance? Not even close. KB, hands down. Look at the december issue of MM&FF and they do a tt vs twin screw vs centrifugal blower test. For all around performance, its not even close. The KB shines. With a KB, you don't really sacrifice anything. A little less top end, a lot more mid and bottom end. I hear a lot of people say, " screw blowers have no top end". That is a fallacy. In the same article, if you compare the Vortec to the KB. Many would think that at high rpms the vortec outshines the KB by a lot. Not true. The Vortec's hp curve (at 11psi) meets the KB hp curve at 5750 rpm. The KB beat's 'em all for all-around performance.
nothing can compare to the hp / boost levels of a properly sized tt setup - I saw that article too Birdie - but looking at real-world performace (the hundreds of cars MPH has turned out, dozens with KB's, hundreds with centrifugal's, and a couple with TT's) - at 8psi most folks with the KB kit are getting 375 or so rwhp with the KB, with the TT their getting 400+ detuned, with more torque.
I'm not doubting the efficiency of tt's or a centrifugal. They are more efficient than a positive displacment blower. -But he asked which is better for 'all around' performance. It's not even close. To me, the only reason you would tt's is for BIG hp, I'm talkin 600+. That is where there efficiency realy shines. Give me any good argument for tt's on stock internals. -You might as well do a centrifugal.
