The advantage, in my own opinion, is with twins you have better response in the bottom end and from a stand still.

you have to look at the class rules in drag racing. Alot of classes only allow "single power adders." that's why you see alot of single turbo cars.
If you go to the "top" classes, you'll see more twin turbo cars. Also, the single turbo cars running in the top classes usually get a weight break compared to those running twins.
for example, in the NMRA Pro 10.5W class, TT race cars have the largest weight penalty (100 pounds over a single turbo car.) also, the twi cars can run up to an 88mm turbo, whereas the single turbo cars can run up to a 106mm turbo.
It is very hard to truly compare twins versus singles when looking at purpose built pro drag cars. Since they have rules to follow (designed to level the playing fields), you can't make a blanket statement that big singles make more power.

Doesn't it also make a difference which engine they are on? A supra has a straight 6, so a single makes sense b/c the piping is straight forward and goes directly to the turbo without having many bends. With our V6 engine we have two banks, so wouldn't twins be the most efficient way to recieve the exhaust? i.e. a y pipe connecting the two banks into a single turbo could create turbulance, reducing the speed at which the air enters the turbine?
Just a question, not sure if the theory is correct or not, but would like to know what others think.

it all depends on teh sizing of the piping....so if its properly sized dont have to worry about turbulance...
In the end, to each their own really..depending on the application, but 1ZweetZ is right: "The fastest cars ran singles in sport compact racing."

What tt kit has less lag and gives more power than then the pl 37r kit your talking about?

The reason the mustangs and big motor cars run twins is because they don't really make a single turbo big enough for those engines that will still fit in the car. Single's are more efficient than twins because there is more loss around two turbine wheels than there is around one.
