All that remains is the 4" MAF housing, top up the coolant & set the new cold air feed. I'll probably need a bracket to keep the thing from running around.

.
hope the bits i done are ok. just wish id had more time todo complete job. looking forward to seeing your motor at york

cool, do you think you will run it at york Dave?

Touch n go - I will try my hardest to get there.

Sorely tempted to get rid, if indeed it's not a valve at all, just a small heater.

The idea of it being a heater has been in my mind for a while actually. I'd read something about it on matthewsvolvosite.

The other thing that's bothering me is the PTC has about a 4-5mm hole to vent through but the rest of the pipework is about 9mm I/D. Could the smaller hole in the valve be there to reduce/restrict flow? could I be pulling loads of extra crud into the turbo? Hmmm... I'll pull a few pipes off in a week or so and see what the Bobby-Moore is.

Well I have all the bits now to assemble the 4" induction. MAF housing showed up. Spent a few hours fettling that. Then after tea I got stuck in with cutting the newly welded 4" J shaped section to size. There is only just enough of a gap between the block and the ABS ECU/pump. I had to push a few brake lines out of the way a bit further & tilt the abs unit on its bracket a bit further up. Tweaked the setup of the new heater hoses & just about got the J in, once I'd cut the bottom bit by some 4 or so inches.

I've marked up all the remaining cuts & holes for the PTC, evap breather and TCV return. Decided to keep it simple and just do a round hole for the PTC - with a grommet that I already have. Also I moved the evap breather & TCV return to the top side because there is just no room underneath now! TCV return may get blanked off - depends if I stick with actuator pressure or not. Took ages to get those holes done - 11mm drill bits - not available at night when you need them, so spent a long time expanding the holes from the biggest HSS bit I had.

Tomorrow I will finish off the polishing of the pipe & hopefully get it all assembled.

Just a few former & new intake shots.

JBS auto MAF housing on the left.

I may yet have to shorten the new MAF housing, but we'll have to see.

Very nice Dave

Very very nice mate

**V70 Graham** · Saturday 18th May 2013, 09:13

Very nice Dave, it's gonna be a tight fit to get it all in the engine bay.

Yes, I've already turned some jubilee clips around just to get the extra 5mm back taken up by the bolt.

Polished up the welds and got the whole thing together. Getting into the turbo end was a bit of a faff, but the PTC & other bits all worked as planned.

Initially it started & died, started & died. I rotated the MAF housing around to allow the air to come a bit straighter on to the sensor. Sure enough - after 20 minutes the ECU got the idea and it seemed fine. Actually better than fine - pretty darn good, plus the idle exhaust smells less rich.

I've put a new cold air feed from under the bumper (as I had before I got rid of the IPD setup).

Sounds pretty awesome too.

Told you it was tight...

New ITG Maxogen filter..

New cold air feed:

Brief video ( if you listen carefully at the end you can hear the turbo still spooling down - or just the birds)

Test run showed pretty well too - IATs no higher at manifold than 21 degrees with 13 degree ambient. No codes & no leaks.

Next step is to get it tuned again.

Looks very nice in there, very professional.
What about removing a fog light and using the gap to have another cold air feed? Or would that spoil the look without giving much benefit?

**Jamest5r** · Sunday 19th May 2013, 00:05

Glad to see its all coming together mate, but i cant hear nothing but bird song

**Wobbly Dave** · Sunday 19th May 2013, 00:07

I'm already using the gap in the splitter - no need to remove a fog light - plus I like them (the fog lights)

Doesn't sound like your temps are that high anyway, either.

Dave, it's a work of art under your bonnet and that video is frightening... Well done

**V70 Graham** · Sunday 19th May 2013, 07:17

Great work Dave, amazing how you fitted it all in.

**T5frankie** · Sunday 19th May 2013, 08:44

looks great Dave, that pipe is mahoosive

**MIKESC70T5** · Sunday 19th May 2013, 08:53

Wow that's very impressive and looks very professional, glad to see people doing things properly and not just mashing things together to get good power for 10 miles then blowing up lol. This is how Volvo should of originally built the c70 t5 engine, well done.
