One reason to run more compression with the V-6 is to help the exahaust velocity. The V-6 with low compression takes a lot of work to get to launch with a big single 88MM and bigger and larger twins like 70MM and bigger with an automatic transmission. If you have a clutch it does not matter, Duttweiler ran low compression in his Olds and has gone 6.8 @ 204 and it could launch on a pro tree. His clutch and BB Turbos helped the car explode off of the line.
I have see several single turbo buicks that sit at the line so long they could never race heads up. They are basically limited to test and tune numbers.
