Been also thinking of trying 1mt length of 75mm silicone hose - only concern with that is that it could colapse internally under heavy load, However it would be easier than moulding pvc pipe!

The world is.your lobster when it comes to hose options. I looked at many options. I eventually went for some spiral steel wire bound high temp exhaust hose, but that wouldn't shape very well for your need.

I assure you, the method you're pursuing is way less involved than the path I chose. And much less intrusive on the engine bay. My only comment is, would it be easier to start off with some rectangular PVC gutter down spout?

And you need to ensure the air box can be removed. Just in case.

Shouldn't cost you much to have the wing-to-a pillar stainless done. My whole snorkel cost $700 to have someone else knock up, so I'd imagine a mandrel bend or two and maybe 1.5m of stainless shouldn't cost more than $300... Easy job.

Be wary of fixing to the A pillar, that trim is removable, so you'll need to ensure you can still do that if you need to, and it will need to fix to the body (not the trim)!

Good work mate!

Should be an interesting outcome.

**FANTOM P38** · 7th July 2014, 08:43 PM

There is already 3 x fixing screws to the A pillar underneath the trim just need to ensure tabs are welded in correct positions. Plus will need to cut out small sections of trim so I'll make up cardboard template for marking up trim.
Good point Sean re Airbox I'll need to think about how best to achieve that or just bite bullet & seal in situ. ( have never had need to take it out yet but never know ).

An interesting project to follow. For me, I'm still not sure I want to start cutting up the old girl though. I still like the original look.

Martin,

at 75mm diameter, you could rent a hydraulic pipe bending machine. Get yourself some st stl pipe. Make it yourself.

Just suggesting (copyright permitting!!)

Anyone see any problem using PVC pipe for the snorkel up the pillar if it's going to get painted anyway? Considering black to match my bar, sliders and wheels.

Inlet temperature maybe?

**davidsonsm** · 8th July 2014, 10:32 AM

Only aesthetics. Assuming you'd be using elbow fittings for the bends, which in my opinion really detracts.

PVC will handle ambient air temp no problem.

**Pete38** · 8th July 2014, 11:34 AM

Well I was contemplating a single pipe and making the bends with sand filled in the tube to make the bends smoother. I think the sand gives a high thermal mass, more consistent heat distribution and restricts the pvc from creasing/folding.

But have never done it so I fear the section changes at the bend will mean it has less diameter at the bend. Although it will only be a gentle bend so maybe not??? Only from an aesthetics point of view, not worried about the flow restriction.

Regards using PVC: I was more thinking intake temperatures and thermal properties/mass because of direct sunlight on the PVC, especially when it's painted black and its summer. I'm not worried about what temperatures the PVC can take.
