ollie_ 0 Posted April 2, 2013 Report Share Posted April 2, 2013 Ok gents, just a quickie. When itb's are used on vr6s, the velocity stacks need to be longer on 3 of the throttles to counter the staggered lengths of the inlet ports... I know this much.My question is, how much longer do they have to be to makes sure all 6 cylinders are matched in length?Cheers! Link to post Share on other sites
Swainy 1 Posted April 2, 2013 Report Share Posted April 2, 2013 When I get round to doing mine I'm going to measure from the valve so all are matched, probably be easier having some made rather than off the shelf items. Link to post Share on other sites
