I'm not offended at all, and I seriously considered a twin screw for my car initially. Keep in mind that my
Vortech V2 is not intercooled (it's a standard S-trim, not the HO version), so I'm running low boost and a very mild tune, accordingly. With Vortech's aftercooler, I would be able to bump boost and the tune way up. A buddy of mine has that setup (Vortech V2 S-trim HO with aftercooler) and is putting down 470 rwhp compared to my 351 rwhp, and he's got a mid-11 second ride to show for it (versus my 12.30's).
Also, why would a twin screw beat me in the short times at the track? I launch at 4,800 rpm's (stall converter), and the revs never fall below that for the whole track so I'm always making good boost for the whole track. My last run down the 1/4 mile yielded a 1.80 sixty foot time, 5.12 330' time, 7.89 @ 90+ 1/8 mile, 10.3 1000' time, and a 12.34 @ 111+ 1/4 mile. My short times are excellent for a heavy automatic car. I've beaten brand new '08 Vettes to the 1/8 mile, and was dead even at the 1/8 mile with a Z06 Vette this season, so I don't feel my launch or low speed acceleration is at all compromised by having a centrifugal blower vs a twin screw.
What I love about a twin screw is the instant torque so that you can incinerate tires on command on the street, but that's not particularly useful at the track when traction is key to winning races. So, a twin screw is fun, while my centrifugal is more focused on results.
