He said built engine, plus said he wants to rev to 8k.

still probably overkill for a red. But a lot of guys like Gary run S3s with smaller turbos and like them

Even if it's built. Only revving to 8k with S3's is a waste, you're needlessly shifting power to the right.

Can you expound on this more? Thanks.

Hi Erik,

i have always found the turbosmart wastegate actuators to have better control over boost. For example the FP 18psi or 22 psi will hit the target boost in midrange and then taper off.. i have found the turbosmart doesn’t do that as long as the turbo can keep up. Also it seems to react better downlow at spoolup so you don’t get the 1-2psi overshoot.
