I dont think it was a coincidence that they didnt name it an HTA 16g. The 47 lb/min number was advertised for a reason....just like the "16g" was left out of the name for a reason. On paper it should kill all 18g's and 20g's on top end power. reality is another story.
Straight from FP's description
"These units are constructed from Genuine MHI 16g turbochargers
which are reconfigured to 68HTA specs by Forced Performance. "
