Any piece of metal that you cut or drill holes in is then weakened, and especially on the front crash bar, as its called that for a reason.

sometimes cutting holes in things actually makes them stronger

Forge one on mine, fits a treat and also aids the car with its bhp figures which have remained very similar over the last few years of ownership.....Sometimes you have to pay for quality, and i for one would rather have a proven/tested bit of kit on my car.

Got mine off of a member on here a few years back and did the crash bar myself.

Great piece of kit Forge, keep up the good work

I have just done a through the rev range temp run with vag-com the max i got was 23 degrees @ 6120rpm in 3rd (7 degree outside temp).

Before the FMIC i was getting 45+ degrees this time of year.

So is the drop enough?

Thats All very well but you BOUGHT YOURS USED!!!!!!!!

I know someone that will be selling a used Jabba Pro Alloy one for an Octy vRS soon...

we have test data for our intercooler which is up to 30 degrees cooler than stock

Ok, fair enough. But what compared with other FMICs?

I'm just trying to figure out where the extra £700 of value comes in?

its not just temp drops, its temp drops, pressure drops, flow rate etc then how well its drops the temps whilts maintaining the flow rate that counts. if you can do that for £200 the excellent.

Vag-com logs indicate a 0-0.2 bar drop across the rev range, i suppose this could be due to less restrictions. Vag-com also indicates a good increase in torque over smic across the rev range also possibly due to less restrictions. all at temps 23 degrees or below.

I have graphs if anyones interested :orb_big_g

... sometimes i just get bored lol

a pressure drop is a bad thing unless the map has been changed.

And your point is......:orb_angry

a pressure drop is a bad thing unless the map has been changed.

Yes that maybe but there are alot of the big brand coolers that have also lost pressure. I cannot see how you can have more air flow through a larger cooler/ pipe work and not loose any pressure whilst also making it cool efficiently.

Let me put it differently, The k03s will put out x amount unrestricted air before pipe work, add restrictions say a small pipework and small cooler and it bottle necks putting more pressure on the turbo.

So your taking the k03s and give it larger cooler and pipe work and giving less restrictions so less pressure on the turbo and more air flow.

bigger pipes don't mean greater airflow, it means lower velocity which if you go too large will decrease power. this is found in exhausts too, go too large with even thinking about back pressure the size increase slows down the exhaust gases which mean you get greater cooling whilst in the exhaust which in turn means greater restriction so making an exhaust larger can lose power and make a car more sluggish.

the same sort of principle applies to boost pipes, increasing size increases lag as your compressing a larger volume of air, its not like having a larger inlet system at all.

yes but at the same time smaller pipes whilst increasing velocity decrease air flow, example blowing down a straw compared to blowing down a 1" pipe. I think the trick is to get it right.

Obviously my pipe work is fine,Power certainly hasn't dropped, i would say increased!

so would you agree most coolers loose pressure and 0 up to 0.2bar in some place is good whilst still keeping excellent inlet temps?

no smaller pipes don't always mean decreased airflow as the velocity increases accordingly. its like pumping mains water through a drain rather than a 15mm pipe, same amount of water but the smaller pipe travels faster to allow the same amount of water to flow.

only if the pump/turbo has the power to increase velocity

Bored now Lol

:popcorn:

kewl job fella and very stealthy, how did u rebead the pipework tho after cutting to size?

they were already bent to various angles as it was a universal pipe kit. I just cut to size with a hacksaw and put a new bead round with this little beauty which i knocked up.

I copied this design from one of the audi sites.

we farmers really know how to bodge, but i works a treat.

The pic won't display Rob but its on post 29 of this thread.

Seriously considering doing something like this.

It has several advantages over buying a kit - cost being one but another being I can get the bits by stealth and avoid SWMBO's monitoring systems

Any opinions on this? Too big?

Too big I think - but the single side input and output are a good thing

Too long and possibly too wide Rob.

Yeah I thought as much. It was the first I found with entry and exit at the same side.

Getting closer but the 180mm height means quite a bit of the cooler is covered by the crash bar.

Mine was exactly the same as this Luxury Sports Bar and plate intercooler 550X140X65 for sale - TradeMe.co.nz - New Zealand

But you could still go a little shorter in the height department. The beauty of these coolers is if you get a stone through one they are dead cheap and easy to replace.
