Hay, don't sweat it. I'm sure people thought this guy was nuts too when he came up with this idea....I wounder how many people told this guy he should run only one turbo..
I injoy being the smart a$$
Yeah, not exactly the same league as what is being discussed here. That guy made all sorts of custom stuff, INCLUDING exhaust manifolds. I'm pretty sure he didn't go dig up some stock manifolds off a SHO.
And for the record, twin turbos are generally used in the place of a single turbo for only a few reasons for aftermarket, and a few more for OEM.
1) Bling factor. Twin turbo sounds cooler than turbo.
2) Packaging. On a V-type engine, it can be quite tidy to tuck the turbos right on the sides of the engine instead of running all the piping to fit a single.
3) For OEM, emissions. Short path to a turbo then a catalytic convertor on each side rather than a long path for both sides to a turbo then a cat, means much better light-off characteristics and better emissions, which gives them more freedom with calibration.
4) For OEM, Lag. Two tiny turbos can give lots of torque off idle, while being choked off up at high rpm. OEMs don't care about the top end as much, but more about how the car drives around town, and what magazine reviewers say.
