McMuttley Posted February 15, 2016 Report Share Posted February 15, 2016 (edited) The rough sketch below represents the extractor against the block (laid on their side) Points X and Y are the bottom and top of the 'flange' against the head. The vertical distance between point 'y' and the point where the collector contacts the block is 260mm. So Question 1: In order for the contact point to be increased to say a safe 10mm between collector and block, i.e., increase the 33mm to at least 43mm... (1a) what would be the necessary reduction in depth of the top of the flange at 'y' (my rough guess is 5mm) (1b) what would be the necessary increase in the thickness of the flange at point 'x' (my rough guess is 2.5mm) Question 2: Assuming that point 'x' is not touching the head, but is away by up to 1mm (due to the collector hitting the block first) (2a) what would be the necessary reduction in depth of the top of the flange at 'y' (2b) what would be the necessary increase in the thickness of the flange at point 'x' Edited February 15, 2016 by McMuttley Quote Link to post Share on other sites
stuart Posted February 15, 2016 Report Share Posted February 15, 2016 Its just wrong and not very well made, send it back.If you try altering the flange like that the stud clamp plates will again not be level and will bend the studs and also not match properly with the inlet manifold.

Fireman049 Posted February 15, 2016 Report Share Posted February 15, 2016 I agree with Stuart ~ Send the damn thing back. Tom. Quote Link to post Share on other sites
iain Posted February 15, 2016 Report Share Posted February 15, 2016 +1 Send it back and get them to sort it. Its never going to be worth the hassle Austin. If you correct this distance whos to say what the next section is going to foul against? Quote Link to post Share on other sites
TriumphV8 Posted February 15, 2016 Report Share Posted February 15, 2016 Unfortunately the required data for calculation are missing. To evaluate the required space you have to rotate the manifold around point "Y". What you need is the distance of the point hitting the block, roughly 300mm away (too much i know) and the distance "Y" - "X" roughly 60mm. So when you need 10mm space at the block you will increase space 60mm/300mm x 10mm = 2mm at point "X" Too much for milling the flange, as I said the tubes must be cut and rewelded, only makes sense without warranty for the bought item.

Alec Pringle Posted February 15, 2016 Report Share Posted February 15, 2016 No bloody way Austin - " der auspuffkrummer ist nicht gut und nicht gut genug ! " Tell the blighters to organise an uplift and refund. It's ****. Deutschland reinventing BL Special Tuning 40 years on . . . . Cheers Alec Quote Link to post Share on other sites
TR NIALL Posted February 15, 2016 Report Share Posted February 15, 2016 One Problem will cause you much Grief to Rectify and when you've that sorted what other Problems will it create further along the System,send it back its way to much Hassle. Quote Link to post Share on other sites
Lebro Posted February 15, 2016 Report Share Posted February 15, 2016 Assuming it is a high port head, the Phoenix manifold as sold by the TR shop for £299 fitted my car very well. Bob. Quote Link to post Share on other sites
