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".

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.

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.
