I know the dahlback will fit the s3,but not sure if it's worth it ,what sort of gains do they quote?
They claim15+bhp gains, but also say when mapped to suit... so perhaps no bolt on gains unless mapped. I asked Hans Dahlback this exact question, and the gains were from mapping and adjusting the boost, so more boost, timing would get you the power anyhows.. I can see it would be better for more evenly distributed cylinder filling via the slot/cone filling but as for more power... Hmmmm
Its a shed load of dosh for next to no gain IMHO...
It cant be reliably ported to suit largeport either, which for me was a requirement. The runners are simply too narrow and insufficient material to port to largeport.
I think Edd Jackson saw gains but sure if these were "bolt on" gains or mapped as well gains. Now he's gone largeport 2.0ltr BIG Sportec turbo he's found out it wont go largeport, so has a step left, which is'nt ideal.
I thought Dahlback were quality but the manifold experience has shown me otherwise in this respect unfortunately. took a dim view of "yes it fits
Ibiza, yes it ports to largeport" to get a sale approach when they obviously have never tried.
Oh well, live and learn
