VXR8 OTR Air filter

[MilkyV6]

I've been thinking for a while that I'd spend some money on an otr filter. I've looked at importing but with tax it works out to be same price as Walkinshaw's unit (coincidence?) So it seems it's a choice between walkinshaw or monkfish. Now the walkinshaw is £540 but MF is over £600 (with in fill panels) so my question is is there any difference between the units apart from the obvious £70???

the Mf one is 425 £ plus 123£ for the panels , that's the otr vcm one which is what i have had happy with it

Been thinking about getting one of these Otr air filter intakes for my r8 aswell,
did you notice any difference in performance after you fitted it ?
sound better?

[vxr2010]

not a massive change , there was a little more induction noise and it felt it pulled better , i personally felt it was worth while , on the dyno with otr air filter map and slight exhaust mode to original exhaust it was 390 at the wheels it's an ls3

Hmm, I'm thinking about this too. As yet, I'm unsure if I should go OTR CAI or an Airaid/Roto-fab type setup. Does anybody have the latter?

I'm sure Ringram had the rotofab version because it flows more air. Unfortunately its a trade off as the air is warmer than from the OTR. I think Richard reckons the trade of is worth it???

I've got a spare kit kicking around if I can find it.

OTR means removing the seal at the from of the engine bay. This lets in salty water in the Winter months. The engine bay of my (Richard's) VXR8 looks like it's been parked in the sea. Everything is rusty as f*ck. Don't do it.

Mines had an OTR fitted to it for years, engine bay is perfectly fine !!!

[vxr2010]

no issues on mine either and had it for some time now , the gap that the air filter gets its air from is not changed by fitting the vcm otr , the intake route for the incoming air is , all that happens is the radiator is tipped back slightly to allow the filter to fit

[bigcraig400]

I'm not planning on using her much over the winter months anyway tbh,so will see, just had a look at the monkfish website and its over 600 bangers with the Extra infill beauty pannels,,,ouch!!!!

[MilkyV6]

Yeah that was my original question on here why is MF circa £60 more expensive than walkinshaw?

[bigcraig400]

Not 100% sure but the m/f one has the cover pannel that goes where the original air box assembly would be,so that's x3 beauty pannels,I don't think that one is included with the walky one,

"why is MF circa £60 more expensive than walkinshaw?"

Walkinshaws are the official importer of HSV parts in this country and the source of many parts for other suppliers?

Who has hacked your profile?

How can there be a 'seal' at the front of the engine bay if you are routing air across the radiator and condenser?

Everything is rusty as fek because parts aren't plated very well and people drive their cars rather than just polishing them.

The Walkinshaw has all the panels too.
To quote from their website - "The Walkinshaw Performance Over the Radiator Cold Air Intake (OTR) comes with their distinctive WP logo and is complimented with the radiator fascia panels and air box in-fill panel to finish to give that distinctive WP OEM look".

Due to the surface area of the filter OTRs become a restriction over roughly 750BHP. Flow better below that number though.

Think the Walkinshaw and VCM OTR are identical ie they are the same. They are over here.
I don't mean they do the same thing because they do that anyway, I mean they are from the same mould.
One will have a Walkinshaw sticker on it the other will have a VCM sticker on it.
Don't know how true it is but I think Walkinshaw may have used a different one early on in the VE Commodore lifecycle.

Looking into it further there is something odd going on!
The one pictured on the Walkinshaw OZ page is different to the one on the Walkinshaw UK page.
The Walkinshaw OZ page is identical to the VCM suite OZ page.
The Walkinshaw UK page item looks identical to the Monkfish (VCM version)page.
Does that all make sense? Looks like Oz has different ones to the UK.

I would try and get one of the latest ones as early ones had difficulties. VCM suite replaced a few of them free of charge which is hats-off to them.
Think they changed the design a few years ago, to one similar to the Harrop version.
Another one is RAMJET which looks similar to what was in the HSV427.
