Hi, new to migweb - been browsing around the forum and was pretty impressed (and overwhelmed) by the amount of technical knowledge on this site.
Been thinking about running tb's on my vectra x20xev. But been told its a bad idea, that power gains will be all top end sacrificing bottom end, plus will encounter loads of other problems ranging from poor cold start to mashed gearboxes! The advice given is that tb's are for track days not road use.
However, most of the people advising have never run tb's so I'm not convinced yet. Would like to hear what people with direct experience of tb's reckon.
Research has just added to my confusion, tapered tb's, direct-to-head, etc (esp., at 1.30am!). Best get to that bit later when moved past the idea of whether it is good idea or not.
Btw, have some of the supporting gear in place anyhow so that's not issue ie, 4 branch, exhaust, cams.
