bad-vw-boy 0 Posted October 7, 2009 I have seen a number of ads in and around re 52mm inlet manifolds for sale, how can i tell what size i have on mine?and is it worth putting larger ones on? and also can you put larger throttle bodies on , from an audi like the 2.2ltr ones i think, is it worth it? :scratch: Quote Share this post Link to post Share on other sites
aide 0 Posted October 7, 2009 you measure the one you have on at the moment, if it's non in/ around 52mm then it's the smaller 40mm one in summary the larger one = better top end, thinner one = better low end, its all about gas speed i'm fairly sure the TB trick you've heard is for the 1.8 8v golfs there was an aftermarket TB called the webber fire breather, basically a large single butterfly, but you hardly ever see these anymore... i missed out on one a few months ago :( Quote Share this post Link to post Share on other sites
