Wagner SQ EVO Exhaust Manifold

[Error404]

You can get them extrude honed where they force abrasive putty through the runners. Aero / motorsport stuff and I would think has the appropriate price tag! There's a place in MK called Extrude Hone Ltd that does it.

EDIT: beaten to it by Andy!

I think extrude hone is a "brand" name for the process, its also called abrasive flow machining

In PPC ? I've been looking for 3 years a place that does extrude honing at a decent price. Can you remember the name I'll look in this months mag I have at home

[AndyP]

There was a place that used to advertise in PPC magazine that offered this service, it's called extrusion honing. I've had similar results by shot blasting, I did this on the chinese RS2 replica manifold I got of Ebay.

How did you do this and get all the way into the runners? I'd like my sq done but can't find a way to do it

On the evo manifold I managed to get all the runners mirror finished using my custom flapper wheel/cartridge roll with extended 8" arbours setup on an electric industrial die grinder (not a dremel, you cant do anything with one if those!) I use for vr6 heads. Not sure if I have the same access on an SQ mani.

Very time consuming job though as you're dealing
with cast. Only did it on mine as I could, if I personally had to pay someone two days work + materials I wouldn't be overly keen of cost vs gains.

As for the blasting material down the runners process I believe it was around £300 many a year back when I looked into it which is again why I decided to spend my own time on the mani. Can't for the life of me remember who the company was though.

i was always told about a technique actually available in the uk, where they can blast diamond dust or some kind of particles through the bores and make them mirror finish smooth. Never managed to find such a shop

I hear there is a forum member with a fetish for dremels that might be able to help...

EVO manifold on mine I smoothed the casting on the inside of the runners and currently made 528hp

Argggg!

mine will take more. as i have a K27 to T3 flange which at least needs modifying to refit, otherwise the downpipe will out of line...

Do you really want me to stay ALL the weekend there changing the EM as well??? hahaha

id be more than happy to sell you that EM, but i thought you already have one! i think i saw one on the shelf!

It would only take an hour or so.... Ask Jamo

I have the fancy 034 tubular one but would prefer a SQ one on my shorty

[Jamo]

Tonks had my em off in record time
