Hi peoples, as the name suggests ive started a new topic. So we can all share in the knoledge. http://austarletclub.com/index.php?/topic/20297-tf035-4cm-vs-6cm-turbine-housing/
I took some pics of the inside of each turbine housing just out of interest. 6cm* 4cm* You can really see how it necks down a lot in the smaller housing, about 1/3rd less id say... Probably more of a restriction than the 35mm turbine exducer. Wait and see.
