Depends on a lot of things. . .

How high are you going to be revving, how high will you be making power, what is the outlet size of the hot size of your IC.

Lots of info to take into account before making a decision like that.

Try to keep airflow in the TB around 300ft/sec any higher and theres a restriction, any slower and you losing throttle resolution.
