I have never posted on 6speed about my Audi (always been about my 997TT) but my S4 finally feels OK again (on dyno #s and it is not my highest #s either) (I've had if for many many years - blew up many many motors; tried at least 12-15 different turbos - all GT30 size-ish) but finally went backward (smaller) and I still have not driven the car to have an impression YET as I just Dyno'ed it Saturday and it has been pouring .. but wanted to share what it's doing so far ...

 

Nice!!! What are your mods? I'm running GT28RS's and only make around 650HP... stock displacement but built bottom end with a ton of supporting mods... 714 is a ton of power on this platform as you know.
Glad to see some S4 old timers are still pushing the platform....

 

anything under the sun - about the S4 is in that car .. stockish displacement. 2.7 block; +2mm pistons ...more
