2011 Audi S5 B8 Sportback
Why is there a hole in the bottom of your intake?I think someone on Audizine already tried fitting a fixed supercharger snout from a previous gen, although it did fit, it didn't work:
"We tried retrofitting a CTUB snout and rotor pack in the blower with the goal of reliability, but while it fit, we couldn't get the ecu happy and it kept making boost at idle."
Hey guys, apparently there was interest in my build as I'm one of the few really trying to push the CREC. As those of you with CRECs know, aftermarket support isn't exactly ideal so I've done some things that some may not recommend and learned some things along the way. This thread will detail...www.audizine.com
By the way, I also had contact with Powerhouse Automotive regarding the supercharger porting, but I didn't go with them as I am from mainland Europe which makes the import/export process cumbersome and expensive (although I would go for them if I would live in the UK).
In the end I got my spare supercharger ported by Startline Motors, they removed quite a bit of material from the supercharger and also checked the state of the supercharger bearings (said they were fine). I will get it installed in the spring, to combine it with some regular maintenance.
