I have just completed this setup on a 1200 coupe using a Ca18det with a 2litre toyota supercharger -----Original Message----- From: [EMAIL PROTECTED] <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Date: Monday, November 05, 2001 4:01 PM Subject: Re: TwinCharger

I am thinking separate plumbing for both systems with a common intercooler and a butterfly valve to close off the supercharger at over 8PSI to avoid pressure loss from the turbo.
