??? Twin Screw who here has seen any twin screws for the focus?
kennebell back in 04 said they were making one but they never did.
You can bet your ass the rouscharger isnt twin scroll.
Superchargers are in no way ever going to be advantageous to a turbo. Coming from the guy that has the best supercharger on the market for his zetec and ended up going turbo... Small turbos spool and make better power faster then a supercharger because I have yet to see a 400whp supercharged root style blower because their not capable. IJS A comparable small turbo with a max 275-300whp will spool at 2000 or less.. I know what kind of heat I saw from 5000-7000 rpm. 200+ degrees compared to a turbo being only a couple over ambient.. How can you compare?
