Can you not put something simple like a small grubscrew (possibly two, one either side) drilled half and half parallel down the interface to supplement the glue. Then all mechanical strength issues go away.

What about this aluminium braze/solder stuff.

Turbo Tel got excellent results.

How thick is the tube going into the bosses?

If anything I'd have thought a disaster with the TIG will knacker the tube, not the boss- they look to have plenty of meat to them to me.

The tube is just 16 gauge or 1.5mm.

Judging the heat balance with Tig will be tricky.

I'd give it a go. If the worst happens and you melt the tube, you can always set the boss up on the mill and mill away the disaster area.

My main concern with Tig is distorting the injector bores and then the boss is scrapped.

The whole reason I've milled this from a single piece is to avoid having to Tig a whole load of parts of varying thickness together.

I'm going to try the EasyWeld stuff. I can fix the runners to the plenumbublium with that as well.

I will have to Tig the plenum end plates though.

Despite the computer telling me that I have Swine Flu and should go to my GP immediately, I've been making the inlet trumpets:


The raw material turned up longer than I ordered, so I had to use the fixed steady.

Not musch happening with this lately due to sorting the 998 and the rolling road. Anyway back on it now.

Made the Inlet Air Control Valve body this morning:

Remind me - what was the source of the idle valve that proved to be the most succesfull with MS? Did it need modifying like the MEMS one did (IIRC)?

This is more recent than early tests but I've got the Rover (Lucas) 4 wire bipolar stepper motor type on a Rover 800 series throttle body (same IACV is used on lots of larger Rover, inc Land Rover, Range Rover) it it works fine with MS2.
Especially the new Extra code (inc. siamese) which allows for closed loop idle control.
This is obviously a fairly recent development of the code if you read the Extra forums.
It took a bit of fiddling with the PID loop to get it stable, and it only idles on the garge floor because I'm STILL welding bits of the shell back together but I like it because it screws straight into the throttle body.
Also leaves the PWM output of MS2 available for boost control.

Well, that one is off a Peugeot and same as the one I'm using on the 998 turbo. No mods needed.

Part No. A95269.

Most will fit, but they have different shaped pintles.

I'm having a week off so decided to crack on with the inlet manifold.



Just need to glue it all together.

This looks amazing mate, hats off to you Paul and you Rod, ive always wanted to have a go at making my own inlet for my VXR project but i can see a cowboy style mess hanging off the back of my engine if i do lol. If this does all work out and you prove it to be a good system and have a few nocked up like you said, i may be interested *wink*

Very neat, alloy I presume.

I had considered doing that for my first one but ended up screwing it together in seperate bits (with loctite fuel grade thread sealant) as I didn't think I could drill the hole the full length (half from each end) with an extended drill without it running off centre.

How did you manage it ???
