Reducing the A/R doesn't help spool-up as much as you think it would. It does a good job of choking off the top end, its the size and pitch of the wheels that really kills spool, plus the fact that you have 1.5 liters feed each turbo. Look at what they typically spool at on a 2.0 and add to that.
What are the goals for the car? Being FWD, a little lag may help you if its a drag car. I know my car came on like a FREIGHT TRAIN when it hit, but then again I was running "all" boost, 33.5psi with the wastegates unplugged.

Thats exactly why I am looking to get something maybe just a little bigger than need be. This will be a street legal purpose built drag car. Completely stripped of everything other than lights pretty much, with a cage so it should be pretty light. Goal is to take down the FWD 3/s record of 10.19. Power goal would like the ability to make 1000whp but would only need ~700-800 most likely.
