see the problem is though when you switch our from twin turbo to single turbo your losing a lot of the low end power so your power band would only be between x (ie 4k rpm) and x ( 8k rpm) not saying that it's not faster that all depends on the size of the turbo but think of it as now that you have a single larger turbo it takes longer for it to spool so theres turbo lag with a twin turbo you have 0 lag because one turbo works the low rpm range and the other works the high range so theres no loss of power.. i've heard of guys shooting NOS directly into the turbo to spool up some of the bigger single turbos faster i dunno i wish i had one lol in time in time..
