Wastgate Exhaust

[Doug_RS2]

I copied Mark (and Tom) and have a seperate wastegate exhaust now.

Although with the standard downpipe it is impossible to get the exhaust to go behind the DP as it will have to go under and will be far too low - the DP has marks on it already. It is sitting exiting straight under the car. I didn't really want to do this becasue Toms sounded like a pile of nails going through the engine but mine is quiet - with the window down is is hard to notice a huge difference (although my exhaust is loud anyway). I don't get those vibrations Tom had through the car.

I think Tom's bend rod must have made it sound like horrible.

1.5" is the largest pipe you can get down the gap - the straight pipe has 5 kinks in it so it fits neatly!

Instead of cutting the small bend off the DP i made a blanking plate with a small bore SS tube following the contours of that bit into the main DP - This is for the vacuum line on the catch tank. I still need to get the other end sorted.

Doug, You getting flames from this by any chance?

If I am, it will be under the car.

Very clever

Doug, can you weld jars of IPA together???

[GandalfS6]

Doug - any noticeble improvement in performance?

I find the glass breaks when trying to weld them

Not noticed anything but I only took it for a short test drive to make sure it wasn't too loud. I'm going for a long drive today so should see if it is better.

Doug did you weld that pipe yourself? also did you place the catch tank pipe at any perticular angle into the d/pipe? does it produce lots of vacuum?

Cracking idea Doug. I've been thinking about plumbing my catch tank into the downpipe as I get oil fumes in the cabin when stationary even with it venting under the wheel arch. I don't want to chop up my Marco special DP(which is still in the dining room!!) so this would seem the ideal solution.

I think I'll order up a new wastegate flexi pipe and hand it over to Carly's dad to adapt Thay way I get the two flanges so he can have a play. Hopefully I can persuade him to fabricate a new flange with a fixing for the catch tank outlet. God knows how much he'll want to charge me though

Martin - when you see it you will see I have welded it myself ! The 10mm SS pipe goes in the bent bit and follows the contours so it is facing the back of the exhaust, in the main downpipe, so it should create a vaccum - I haven't plugged a meter onto it yet to see if it works or how much of a vacuum I get.

Ben - I am getting oil on my catch tank but it must only be wilhile thradshing it as I don't get any fumes in the car - or the filter is only splurtting the oil out during a thrash and it is just building up pressure when idling.

You can buy the wastegate flanges - I have a spare one left.

Get a mig and do it yoursefl - I have!

[Doug_RS2]

There is only about 5 inches of SS 10mm pipe sticking out the exhaust - I angled it so the hose would go round the brake fluid reservoir in case it all got hot but the end where the hose connects doesn't get hot - you can hold it after a thrash.

Have you filled your tank with scouring pads yet? Mine seems to be working perfectly. It's still very team bodge with an ASDA pesto jar on the bottom of the tank to catch the drained oil. Carlys dad is knocking up a custom sump plug for me and the last adaptor I need for the back of the head. Should be done in the next week or so.

I'd love to have a go myself but time always seems to be against me. I work 11 hour days now and when I get home it takes so long for the car to cool down it's dark before you can do any work on it Living in a terraced house means I don't have a garage either.

And I'm not sure I understand the concept of actually buying bits for my car. You mean I'm supposed to pay for things?

Nothing wrong with Team Bodge Live on the edge!!

[Doug_RS2]

Mark did get me some SS scouring pads to stuff in my tank - I was going to get a filter for the drain before fitting it - I might stuff them in anyway - to see if it makes a difference.
