Yeah, but the GT3 is lighter than the GT2, by some 100kgs approx.

Kevin, any sound files available for your exhaust system?

Bill,

</font><blockquote><font size="1" face="Verdana,Tahoma,Arial,Helvetica,Geneva">quote:</font><hr /><font size="2" face="Verdana,Tahoma,Arial,Helvetica,Geneva"> As I recall from various discussions, measured compression ratio's shows the stock 964 around .5 or .6 below the 11.3 spec. Advancing the timing and bringing the compression ratio up to spec might be a reason to spec 98 RON.

Will save hacking at the pistons if I supercharge though knowing my luck it will be the one thing that is correct.

do you have some more chip work to do? I would expect slightly better returns from an adjustable FPR and headers.

I agree that the 'shape' of torque delivery is more imprtant than headline HP figures.

YOu look to have made some good improvements.
