LJ 0 Posted July 20, 2005 Bored at work so found this on Vortex, as you do: 8v xflow head CFM - anyone with numbers?? Just got me wondering if anyone has the numbers for the PG counter flow head? Can't find anything on Vortex. I know the PG is not great, but just wondered how bad it was. USA guy mentions ~155CFM for a standard 2l ABA xflow head, and with mild work can get around 180's to 190's. In another Vortex post one guy said the SC could possibly max around 300CFM. Hence why the PSI readings will suddenly increase at the top end as the PG can't handle what the SC chucks at it...? Quote Share this post Link to post Share on other sites
