Unless of course, you have no need for traction. I can't imagine a 600hp Z being butt loads faster than an 800hp one.

You get faster spool by bringing the turbos much closer to the exhaust ports and you keep exhaust pulses from colliding with one another... but there are a lot of great builds using the BP kit these days and it looks like they build boost pretty fast to me.. he uses a twin scroll turbo so it eliminates the exhaust pulse issue.
One potential downside of the BP design is the turbo sits low and is at slightly more risk of getting hit by something and you probably couldnt drive through minor flooding - I am only speculating here though.
Other than that... the twins are more expensive, complex, and laborious to install.
Both types of kits have pros and cons... I love my twin turbos and I got a crazy good deal on my kit... But if I was weighing my options now it would be pretty tough not to get a BP kit.
