Turbo sizes and why?

[The Jake]

Why do some people go for a huge single turbo (e.g. T88) and others a smaller, twin turbo?

What would the difference be in terms of power output?

it all depends on what the application is. If you want drag, curcit, drift or street or a mix of all of them. Generally(on the street) if you want better resonse you would go for a small twin setup which give a broader power band and better spool up time. However in terms of drag racing, the only limiting factor behind a big single is the power output. most of these are limited to around 800-1000ps whereas a twin set can go 1100ps and beyond. Also cost is invloved. If you have a twin setup you need two turbos, manifolds, set of lines etc. So really it is a comprimise between what you want and what you can afford.

Yeh... what he said ^

If you have long term goals for your car & how much power you want to end up making you'd buy the appropriate sized turbo.

Next turbo i get will be good for around 550 hp I'd say.

depending on your setup, you can get a big single to give the same response of a smaller TT setup.
