dohcturbo626 Posted December 14, 2012 Share Posted December 14, 2012 just buy good tube nothing covered in wanabe crome its crap to weld and united flexable sell the cheapest malory clamps around i paid about $1.80 nz for zinc 1s. also agree with the above post about silicon it allows the stuff to move and a good clamp will hold it under alot of boost.

sgtjackass Posted December 17, 2012 Author Share Posted December 17, 2012 So the kit arrived from redline. $150 bux included so much stuff, clamps joiners and pipe. Removed all the 1.5 - 2inch crush bent piping. Who the f**k puts 1.5 inch crush bends on an intercooler. 2 hours later- had to cut most of the pipes to fit, and had to holesaw a 3" hole through a panel but too easy. Bumper even fit perfectly So its all 2.5 inch now, and i honestly recon I doubled the power. It lights up all four really easy now. Couldnt be more stoked how it worked out. Cheers for everyones help Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted December 17, 2012 Share Posted December 17, 2012 each silicone joiner adds 2 to 8hp depending on color..... you did the right thing Quote Link to comment Share on other sites More sharing options...
sgtjackass Posted December 17, 2012 Author Share Posted December 17, 2012 Thats great to hear. Well I used a selection of black and blue so I should get the maximium HP gain right? Quote Link to comment Share on other sites More sharing options...
fuel Posted December 17, 2012 Share Posted December 17, 2012 The 1.5-2" crush-bent piping seems to support the factory 250hp they make OK? My VR-4 Evo has 2" piping at its smallest section and only one large radius crush bend and it still seems be be OK for a 20G turbo to not have much more lag than the original 16G turbo. Although I would like to replace some of the piping and enlargen the intercooler end tank inlet/outlets. Quote Link to comment Share on other sites More sharing options...
fuel Posted December 17, 2012 Share Posted December 17, 2012 hang on just realised this is for the RVR - yeah I think they did have smaller piping than the Evo for some reason - at least you didn't have the top mount intercooler model.

sgtjackass Posted December 17, 2012 Author Share Posted December 17, 2012 The piping was absolutely tiny. And not factory. SOme/most of the joiners were kinked and some had gotten holes in them, so they had just wrapped another one on top. Im glad the whole car isnt 'modified' to such a poor standard. The 2.5" piping gave more response and less lag. Quote Link to comment Share on other sites More sharing options...
Shandangles Posted December 18, 2012 Share Posted December 18, 2012 from memory 2" id piping is more than enough for 400hp, can t remember where i read it but is in the brain. not that it matters now with your 2.5" stuff Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted December 18, 2012 Share Posted December 18, 2012 even though your tb might be 40mm you will still get less flow restriction by going to pipe larger than 40mm. something about the resistance of the air on the walls of the tube or something something Quote Link to comment Share on other sites More sharing options...
Llama Posted December 18, 2012 Share Posted December 18, 2012 Pipe contact area increases in proportion to diameter. Velocity decreases in proportion to diameter squared. Friction force is proportional to velocity squared (but also reynolds number, which contains a velocity term). So yeah, frictional losses will be decreased with a bigger pipe.

kpr Posted December 18, 2012 Share Posted December 18, 2012 throttle body is going to be more restrictive, than a pipe the same diameter and length Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 27, 2013 Share Posted April 27, 2013 From ozgemini forums Hey all...Got this idea from another forum. This is a home made bead roller for your intercooler piping. Of course you can drop a couple of welds onto the outside edge of the pipe. However not everyone can ally weld if you are using ally pipe' date=' and this is an easy method to produce a proper neat bead. This tool will make a bead in mild steel pipe as well but takes a little longer. I tried 2mm aluminium tube and also 2mm steel/chrome exhaust end with great results from the aluminium tube, but was much harder to work with the exhaust ends, so I gave up on them. If you were to use normal 1.6mm mild steel exhaust tube then there would be no dramas. For the sake of the thread, my pipe is 2.5"OD. 1 large set of vice grips - $12 1 exhaust clamp (size to suit your pipes) - $3 1 large washer - 30c Note the large washer in the picture below is not the one I ended up using. Weld the exhaust clamp together back to front. Weld them together as pictured below... I did 2 passes around each end of this elbow. Tighten the vice grips a little after each pass to make a deeper bead... Hope this helps anyone setting up their intercooler plumbing...

JoKer Posted April 27, 2013 Share Posted April 27, 2013 why would yo need to weld the exhaust clamp 'together" like that? the loop appears to do nothing (maybe add strength/look pretty) Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 27, 2013 Share Posted April 27, 2013 Yeah I thought the same thing- guess its adding strength? Would be better if Center was fixed too. I'm sure there must be better ways of doing this- unsure why nothing is commercially available that's cheap and handheld. Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted April 27, 2013 Share Posted April 27, 2013 Oh my god. Best idea ever Just make new jaws with rollers fitted that u can bolt in 1 Quote Link to comment Share on other sites More sharing options...
Yowzer Posted April 28, 2013 Share Posted April 28, 2013 I think ima gonna do that to mine. 20psi likes to pop the joiners pretty easily Quote Link to comment Share on other sites More sharing options...
