arasta Occasional Poster Location: brisvegas Registered: December 2004	Re: What head specs for 4agte Wed, 09 February 2005 07:50 just reading up on 4ages last night and i came across something commenting on cams + durations. (try google search for 4age cam duration or similar and see how you go.) from what i gather setting up the exh duration one 'step' lower than inlet is to do with torque and where in the band it comes on. you also have tuning by using adjustable cam gears to bring it in or out - i.e. retarding inlet slightly, while advancing exhaust, or vice versa, or advancing and retarding both in step. as the page says tho you really need to be doing this on a dyno so you can immediately see whre the results are. you also need to be thinking about the sort of tuning you want - the page mentions for example accel from 0 type tuning, or tuning for between specific rev ranges (usedful for track type events i thinking where you would be trying to keep the RPMs up and pulling, and accel from 0 type tuning is not much use) aaah i think ive found it : http://www.club4ag.com/faq%20and%20tech_pages/4A-G E%20camshaft_story.htm dont mind what i wrote before go and read it from th hoss' mouth Cheers [Report message to a moderator]
