supra_ufo Posted September 23, 2014 Share Posted September 23, 2014 My jubilee were popping off underboost so I need some upgraded ones, I measured the internal diameter of the stock pipework as 74mm... Do I need the clamp size of 73-79 or 68-73mm? http://www.ebay.co.uk/itm/130613337258?_trksid=p2055119.m1438.l2649&var=430040902781&ssPageName=STRK%3AMEBIDX%3AIT thanks.

RobUK Posted September 23, 2014 Share Posted September 23, 2014 Have you tried genuine jubilee? Also have a look at Murray clamps... Quote Link to comment Share on other sites More sharing options...
ashbuster Posted September 23, 2014 Share Posted September 23, 2014 how thick is the pipe bud? are you using stock black pipe or some sort of samco hose? if you use a samco and its around 4mm thick(maybe thicker) then you are looking at the size 79mm-85mm because you have the internal which is 74 + the extra 8mm thickness pipe = 82mm it will compress down when clamped but if you were to get the 73-79mm clamp you would have a hard game getting it on and you wouldnt get the 68-73mm on at all bud if your still using the stock pipe then you can just check the thickness and work it out bud or post back i forgot the thickness of the stock pipe but i think it maybe close to 4mm, Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted September 24, 2014 Share Posted September 24, 2014 I'd go for the 73-79 mm to allow for the hoses as Ash says Quote Link to comment Share on other sites More sharing options...
supra_ufo Posted September 24, 2014 Author Share Posted September 24, 2014 I am using an ebay intercooler pipework with ASH (auto silicone hose) its slightly thicker than the hose that came with the ebay kit I will go for the bigger clamp size, worse case I can always send it back Quote Link to comment Share on other sites More sharing options...
