The wiring wiil need to be finished. Oil lines are under work, petrol lines need to be made and the radiator and water lines are still to be done.
I'm still missing the racing gearbox but I'll get it running and RR'd with the std box.

Re: Also...

cool, least theres not too much left to do,

when are you hoping to have the car ready? wouldnt mind seeing some vids when its all finished

No, it's mild steel. I'm taking it to be coated tough. So hopefully it will not get the oh so pretty rusty coating. And the coating doubles as a heat wrap.

Car has to be ready by June when the season starts. But I'm hoping to get it done and set up way sooner. Would be nice to do some practice runs. I've been out of the car for a year now and my wrists may be a little stiff.

Re: DIY mani

Finished the metal work on the manifold today. Welded the primary tubes to the flange. Welded on the thread for the lambda sensor. And added a piece of tube to the collector to connect it to the exhaust pipe.
And added the hooks for the springs to keep the primaries from sliding out of the collector. I was thinking of using locking wire instead of springs tough
All ready to be coated now.

Re: DIY mani

Here is a pic of the manifold connected to the exhaust pipe I took while at the garage.
Does not look restrictive at all

Note the spark plug for the afterburner effect.

Re: DIY mani

A pair of stiff springs works for me on my sliding joint , in the forest rallies... but maybe a lockwire with a slight bit of slack in it too?

[Roadsport]

Re: DIY mani

Slide joint? Why does it need to slide ? Is it a rally thing I've not heard of ?
Cant see why does it have to? My only goal is to keep the primaries tight all the way in the colector thus preventing any leaks. I was originally thinking of spot welding it on. But decided to keep it removeable if I were to try out different lenghts of primaries. Only flexible part in the exhaust systems are the mounting rubber bushes. Well if it needs to slide I can teel from the broken wires.

I took the manifold to be coated today. We decided to do two layers of cheramic coating on it. The insides will be coated wtih highly insulating cheramic. And the outside with less insulating, more corrosion resistant more attractive silky matt gray cheramic. Both can handle over 1100C of heat. Should be ready in week or so.

Re: DIY mani

Sliders with heavy springs to allow the tiny high frequency vibrations of the engine especially at high revs......therefore avoids cracks. Don't slide as such, just allow the little movements.

I'd say wires will allow that too. No matter how tight I twist them thery will not be totally solid. Never been a fan of these dodgy springs I hate putting them on and taking off. Even tough I need to do it next to never I thought I'd try a shortcut this time. If the wires do not work or cope with the vibrations I'll reluctantly go back to springs.

Hows your engine doing?
