i suspect the fuel is a bit more octane than you need... lower octane may yield more power unless you have the compression to take advantage of high octane.

that timing sounds pretty low. for that octane fuel anyway.
Standard is 10 degrees in North American A12's and 7 degrees in aussie and nz if i recal correctly.

Valve clearance: What your cam vendor recommends. For stock camshaft it is 0.35mm intake and 0.35mm exhaust HOT.



Quote:That sounds about right for RWHP "at the wheels" for an A14. Stock ratings for the 2007 A14 are 47kw & 97 n-m -- "at the flywheel".
