I'm just curious as to why everyone is going twin turbo on the Viper, and not with an huge single turbo?....id like to know the reasons for this just because the Supra guys seem to have found the big single route is the way to go....same with us Mustang guys(started out with everyone doing twins but now everyone is finding the big singles are better)....
....i dont mean this as an attack in anyway, or an attempt to try and say i know more about Viper tuning than any of you guys just a serious question...

Anthony, You are asking a very good/natural question. I am planning on doing a single turbo and have figured out exactly how to do it. I am just going to finish up my big twin setup first. The properly sized single turbo will be awesome on a stock motor for about 800 RWHP and slightly more torque. One thing that is a little more challenging for the single turbo is the fact that the size of the intake and exhaust piping and the radius of a 4" on 4" exhaust and the 5" on 5" inlet is not easy to squeeze into the Viper engine compartment. I already have a mockup single turbo on order to start to calculate and index the exact fitment of all associated plumbing.
There will be no lag with the single turbo and 8 liters/10 exhaust pulses spooling that bad boy all the time.
The other good thing about the single turbo is the fact that it can make equal power to the smaller twin setups but be more cost effective for the customer. I have several people lined up for the winter months to do the single turbo. Compared to what I have done on my car, this will be simple as can be.
P.S. I have also designed my twin turbo setup to have the flexibility of using a pair of turbos the size of the single (give or take) singles in place of my twins depending on how things go. The twins I am using so far are only the starting point.
