Thanks. <a href="https://www.a5oc.com/forums/images/smilies/smile.gif" border="0" alt="" title="Smile" >:-)</a>
By looking at the supercharger speeds on APR's graph, just swapping the crank pulley gives a decent increase in SC speed. I'm not looking for the ultimate tune, just the most cost effective gains without stressing any engine parts to the limit.
So I'm thinking crank pulley and remap. <a href="https://www.a5oc.com/forums/images/smilies/smile.gif" border="0" alt="" title="Smile" >:-)</a>
By the way, what is the stock charge cooling system on the 3.0TFSi, is it air to air or water? I can see what looks like an intercooler at the front low down, same position as the TDi intercoolers.
I'm waiting for the recall notice. If I don't get one then it proves that it is not a genuine safety issue but a theoretical one (i.e. no actual reported failures on the CREC, but a risk assessment has concluded that based on related parts/suppliers the risk is sufficient to do the replacement only on a "when the car is at the dealer for another reason" basis). I don't really want an unknown level of competence Audi tech doing the job on my car unless I have to. I have inspected my fuel rails and can't find any sign of leakage.
Bear in mind that when sizing your ratio upgrade, at every point in the Rev range the charger speed is potentially higher. Peak power goes up but so does can torque - everywhere!
I wouldn’t worry about supercharger clutch slip if you buy the right belt and tension it properly.
I would advise buying the ones supplied by iAbed. Gates motorsport belts.
Dippy, please explain your asterisked comment above!!!
