Is that your welding - if so  :notworthy:
I wish. My friend has sorted me out with all the welding so far.

The way I see it is, it would cost me £300 for a decent tig welder and a bottle of argon, then I would have to learn how to weld no where near his capabilities,

Or I take that £300 and pay him to do  all my bits and pieces needed. Bargain if you ask me

I'm mightily impressed with how small they are, think he told me a while ago that when pieces are perfectly flush you barely need any filler rod

Correct, called autogenous welding, just create the pool from the parent material.

If you get the pulse frequency correct you can create a nice dime effect with pulse and just move the torch.

Did 95 % of my exhaust welds with no filler rod.

Easy on a butt weld, but that one you have with the flange on the end you don’t have a lot of choice but use a rod

Yeh the v band defo needed rod as there's always a slight gap.

In other news, taking to my friend with a full chassis rx8 he casually tells me he has revved his 2 rotor to 17000 rpm.....

205 litre drum of methanol £400

That's 45 gallons, roughly 1.5 gallons per run

= 90 passes

Race fuel according to James used to cost him 3-400 per event

This is why I'm glad I'm going for methanol

Now where can I store it

Got the rad and cell in a rough position so I can work out what material  to take out of the front clip

Cut the front clip, left enough material at the sides so I have something to weld new pieces too, efficient use of the jack and box to get them in almost the exactish position.

The cell has to go on the rhs in the picture because the mechanical fuel pump mounts to that side of the engine which means nice straight short fuel lines into it.

Had a rough measurement of how much fuel line I'm going to need, around 2.5 - 3metres worth of PTFE fuel line which should guve me a little bit spare when I'm done

Using PTFE line as it is best for methanol

Thinking of removing a bit more metal around here  so I can get the fuel line straps mounted to the same piece and they are the same length

I need to get some decent size pieces of cardboard now so that I can make templates for the brakets etc

A slight has occurred to me that I might have to put a "bash bar" back in Infront of the fuel cell and sitting behind the front bumper just incase car decides to eat wall help prevent the cell getting full impact but we shall see. Not currently on top of the essentials list right now

Just realised after all this that I haven't got thr front ARB in and had the terrible thought something was going to hit it

Luckily nothing in the way, phew.

But dark but how they look inside the car, think the rad needs to step back 50mm mayb so I can get my hand around the filler cap, filler cap sits above engine so hopefully air won't get stuck in the engine.

Cell may have to go down 30mm as then it will give me enough room to re use the overflow/ast from the mx5.

And still leave enough room for filling the cell

Thinking of possibly mounting it here, if need it or not or just use a coke bottle. Like most people do is another question

Tried it back in the standard location, however it looks crap there and impedes on the rad

Certainly not a criticism, merely an observation as it’s all coming along nicely now, but  can you not swivel the front of the turbo around which will let the pipe with X become shorter and all allow more room for the air filter.

I have a saying “a different pair of eyes” sometimes helps.
 
All the best Clive
