I have a simple question. Do you have to run dual cp3's with twins? If not then what are the reasons for another cp3.... I know more fuel/fuel pressure, but if one is enough for twins then shouldn't only the hardcore racers and pullers need them?

I just run one CP3, you don't have to run 2. A lot of it depends on tuning and how fast you want to go. Larger injectors are a good reason for dual CP3's but you'll want a build motor to be running hard with that much fuel.

That was my next question... shouldn't you be worried about the internals with that kinda power?

Well I'm no expert but at my power level with the twins I should be fine. Its cylinder pressure and heat that causes problems for the internals and compound twins keep both to a minimum for the amount of power they provide. With my setup and max effort single CP3 tuning I cant get above 1275* up to 100mph.

Well sweet! I like the sound of that! I think I can see twins in my future! After about a thousand other things!

My birthday is coming up next week so I went ahead and bought myself a present, an s475 to twin with the stock turbo. Bought a complete flange kit as well now all I need to do is order the tubing, oil lines, other miscellaneous things and relocate battery and coolant tank, make the mounts for turbo as well.
my bday is tomorrow bro!
