need4speed Posted March 4, 2017 Share Posted March 4, 2017 Ok so the AFM unit has a diameter of 80mm and the plenum 72mm. Given the route my hoses are going to take I need a 135 degree reducer - which I can't seem to find in these dimensions OR flexible reducing intake hose. Any ideas?

Bowie69 Posted March 4, 2017 Share Posted March 4, 2017 With megasquirt? No need for AFM... I have in the past found a straight reducer, but not sure you need one yet Quote Link to comment Share on other sites More sharing options...
steve200TDi Posted March 4, 2017 Share Posted March 4, 2017 I'm about to update my Racer build thread with my intake progression. I found a 70mm hose fitted the intake, but your quite right, you can't get 135 degree reducers and there's limited 90 reducers as I found out! It a bit of trial and error and find the best combinations of reducing bends and straights! Steve Quote Link to comment Share on other sites More sharing options...
need4speed Posted March 4, 2017 Author Share Posted March 4, 2017 Pete not AFM as such. More the AFM replacement from niges kit. I should have been clearer sorry. Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted March 4, 2017 Share Posted March 4, 2017 Ah Have done this with a 90, then a piece of pipe, and then a 45, gives you more option for adjustment fore and aft to reach the filter behind the plenum. I would think a 135 would be too limiting. I'm now wondering why nige's kits uses a different size... Any how, I am sure you can get a silicon 90 with 70/80mm ends.

bodumatau Posted March 5, 2017 Share Posted March 5, 2017 I used silicon hoses I bought on fleabay for about 20-30€ each, you could buy a 90 with a reducer from 80-72 in it, then cut the 90 off somewhere in the bend to get the right angle. those AFM pipes of Nigels have a flared end so it wont really matter if you only have enough pipe over the tube to get a hose clamp on. but that would put the AFM pipe very close to your plenum. I had to shorten my 90 degree silicon hose onto the plenum to be as short as possible so my AFM pipe could fit past my brake booster (LHD the brake booster is on the other side) Quote Link to comment Share on other sites More sharing options...
Cheesy Posted March 5, 2017 Share Posted March 5, 2017 I used a 90 degree exhaust elbow cut and welded to give this path, the elbow is 76mm and so is the silicone joiner, at the plenium I cut a strip of the steel tube and split it so it fitted over the spigot, put a little bit of RTV at the split and clamped the silicone joiner over it. The manky pod filter is being replaced with a TDi filter which will connect to a snorkel Quote Link to comment Share on other sites More sharing options...
dangerous doug Posted March 8, 2017 Share Posted March 8, 2017 I had a similar issue, in the end i bought a straight reducer and cut it down to get rid of the awkward size. Then made a new section of tube for the air temp sensor that went between my reducer and the 90° for the throttle body Quote Link to comment Share on other sites More sharing options...
DavidW Posted March 15, 2017 Share Posted March 15, 2017 Hopefully the attached photo will work and show how I've just got around a similar problem. The bend after the the manifold is a reducer from Ebay for about £20. The supplier seems to have pretty much every combination going. All the best.

Bowie69 Posted March 15, 2017 Share Posted March 15, 2017 Awesome, thank you It seemed familiar, so a quick search of my email brought up about half a dozen purchases from them, all been very good for me, and as you say a huge range.

FridgeFreezer Posted March 15, 2017 Share Posted March 15, 2017 I've used Autosiliconehoses (ASH) for a fair few bits, they seem about the best value UK supplier on eBlag. Quote Link to comment Share on other sites More sharing options...
bodumatau Posted March 16, 2017 Share Posted March 16, 2017 one of these might also help, http://www.ebay.co.uk/itm/90-Degree-Alloy-Elbow-Bends-Aluminium-Lightweight-Metal-Pipe-Swaged-Polished/200967481273?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D2%26asc%3D20140122125356%26meid%3D4226ee561aca4d86b9426774f34f11a6%26pid%3D100005%26rk%3D2%26rkt%3D6%26mehot%3Dpp%26sd%3D351017950576 Quote Link to comment Share on other sites More sharing options...
