As if we didn't talk about this enough already! 
It has been the discussion of numerous off-line conversations but at Carlisle it was discussed even further directly with Callaway. With their break-through into the C5 marketplace with various performance upgrade and cosmetic parts, it is hopeful that they'll take the time to design a new intake similar to the LT1 intake. This would allow extended breathing permitting higher rpm output and a much broader torque range. It was also discussed that this new product could involve removing the oversized GM HEI distributor and putting in a much smaller distributor so as to give the #7 and #8 cylinders uncompromised air-flow.
It doesn't seem too difficult to come up with a product because there are a few options out there already that can be reverse engineered to make the Callaway product even better (Holley Stealth ram & TPIS mini-ram) Nothing like doing something better by learning from everyone else's mistakes Conceivably if the product is developed it could be geared towards a broad market. In other words, the TPI intakes of the Twin Turbo era are basically stock-ish GM TPI intakes which every C4 Vette has from '85 to '91. If Callaway were to develop this new manifold it could be marketed to every C4 owner and, of course, there would be special packaging and other parts required for the Twin Turbo 100+ package.
Me? I'd buy it just to get another 1500-2000 of useable torque without increasing the peak output of the motor!
