Single 106+mm or twin 91mm...
Personally i would go with twin 88's or the 106. I like big singles better than twins, i vote 106.
EDIT. with twins i would go bigger than 76's just for the room to grow if you so desire, but i do agree with Shawn@VASpeed, they will get it done.

Hey everyone,
This is my first post so please forgive me if i leave out some information.
Now as i live in Australia i have a Holden commodore ute which previously had a built LS1 with a single turbo making around 450rwkw (614hp) on low boost.
Unfortunatly due to a bad performance shop that motor went bang so i have stepped it up and gone for a 427ci LSX block with a the best of the best.
its has a 3000hp fuel system, Fully built custom T400 with transbrake, custom rear end etc.
Now everything is complete and the motor is in the car but i have been having a hard time deciding between deciding if i should go a single or a twin configuration.
The car is used primareraly for racing but needs to be able to be driven on the street as there are some street meets that i attend.
Obviously with turbos this size im looking to run well past the 1000whp mark with the motor built to take 30psi all day everyday that will not be a problem.
if you could give me some real world information, your thoughs about each setup and particular brands (here we really only use garrett but looking to expand to something new) that would be great.
Cheers.

Thanks for your help guys.
Im going to be hearding down the path of a big single turbo.
More than likely the Precision as its billet but i will look into turbonetics and co
For those wanting pics of the car there is a thread in the introduction section with photos of it before with the old turbo setup and look (under going a massive amount of work now).
This car is really just being built for an all around which looks good, makes some power and runs a respectable time eg: shows, dyno, racing.
I have a connection to this ute as it was my first "real" car when i was 20 im only 24 now so theres plenty of time left to try different motors, rear ends, paint, wheels etc
