I managed to hit a stroke of luck whilst looking at upgrading my previous intake.

Initially I was after purchasing the new forge twintake which has had alot of press on the forums recently but after contacting them about fitment to the vRS they said that the bottom filter wouldnt align as it was slightly different behind the left wing and headlamp.

I then spoke to ITG who seemd like the nearest competition and instantly got a response back offering to do the design of the new filter for the vRS on my car for a diiscounted price:D:thumbup:

ITG were initially asked by REVO to design an intake for their demo Leon cupra, that could provide more imrpovments in induction than the other options available on the market.

Mine was the last of the Vag vehicles to have the filter designed for it. Now they have the full spectrum from skoda, seat through to audi in all the TFSI engines.

So here it is:

The guys that fitted was from what i could tell suffering with OCD as this intake has been mega over designed. For example on the inlet for the turbo there is a 5mm lip which disturbs the air flow as it enters the turbo, they have a specially designed Silicone pipe that has a lip on the inside to ensure that there is no disruption of flow.

He also insisted that the pipework before the MAF housing should be of a larger bore than the MAF to reduce drag on the inside especially on the bends, but it also act like a venturi tube increasing the pressure and speed of the air flowing through the maf.(every little helps i guess)

If you look at the next pictures you can see they have also completely sealed the filter off from the engine bay to ensure that none of the hot air(as far as is possible anyway) from the engine will get to the filter. I prety confident about that aswell as he spent ages with a torch trying to see gaps where air could get through, and then resizing the heat shield to remove that issue.

As well as that, the top of the heat shield has been cut so that it folows the line of the bonnet, as well as further heat shield ontop of the batteries

As you can see the filter is huge and cylindrical on this picture but the intakes available for the rest of the market will have a slightly smaller cone shaped filter. As it will fit all aplications better.

You can see where the air is coming up from just below the headlight. I am planning on removing my headlamps and fitting ducting form the resulting holes, so that i can even colder air blasting it from below, as well as cooling ducts for my brakes.(but i am pretty sad, so theres no need to really)

What i love most i the sounds this thing makes. I had the code red intake before which i thought was pretty loud, im sure fikes75 will back me up there, but this is in another league.

You can hear the air being sucked in when accelrating especially when in low revs and a higher gears, zand in between gear changes it sort of sounds like the blow off valve i used to have but with chirps and flutters thrown in.

I absolutely love it. in words its kinda a ssssshhhhhhhhh whoosh flutter fluter noise. but the good news is its only like that when you use the loud pedal aggressively.

AFAIK this is retailing at 300+vat so its slightly more than the evoms but quite a bit less than the twintake. I think if I already had an evoms i wouldnt bother unless I could sell the evoms fro a decent second hand price.

Im waiting on the guys on mk5gti forum to do some logging. they are also running it on a dyno with stock airbox on then fitting the ITG intake straight after to see the imropovments made. ill post them as soon as they are done.

I expect it to be large. my car was quite jerky for a while after fitting as the car hesitated with the air fuel ratio out of sync, but once the ECU had adapted, which took about 15-20 miles it was as smooth as and much more responsive.

He also insisted that the pipework before the MAF housing should be of a larger bore than the MAF to reduce drag on the inside especially on the bends, but it also act like a venturi tube increasing the pressure and speed of the air flowing through the maf.(And from a physics point of view this is all correct, plus i suppose every little helps)

I can't agree with that. Air to the MAF should be as undisturbed as possible (for at least 4-6 inches before the MAF) otherwise it can skew the readings which will make the car overfuel as it thinks the air flow is higher than it is.

Looks like a decent job there!

the air is undisturbed, the pipe is lipped before entering the maf so it is undisturbed, the only difference is its velocity and mass/second flowing through is increased.

the right hand edge of the MAF housing is about 4-6 inches though anyway though surely

It looks rediculously overkill, I love it!

Looks very nice indeed

Sorry Sy but I disagree with your physics. The venturi effect means that as the diameter reduces the gas speeds up and reduces the pressure.

But you don't actually have any more air entering the engine. All you're going to do is make the same amount of air go past the sensor at a faster rate, which is going to do nothing apart from fool the sensor into giving a higher reading which will only result in overfuelling if it even has any effect at all. Either way it's not a positive result.

you are very correct there i but the important fact is that the gases speed up so you get a larger amount of mass going through per second, therfore a higher maf reading.

You have the same mass of air going through, just at a faster speed past the sensor.

Actually Sy you really should read the link I posted.

Its all down to conservation of energy. If the gas speeds up there will be less of it but it will be going faster.

Simples.

You have the same mass of air going through, just at a faster speed past the sensor.

fair one, the only way to get the extra mass is for the air to be colder, and therfore denser.

Ignoring the physics side of it though, and as you can see my physics is flawed (im just a lowly electrician by trade) i was merely trying to point out that i thought the attention to detail seemed to be excellent and it was a viable option to the evoms which has always been the bench mark really.

I recently had logs done on my car before the ITG intake was done, if i can find someone local to me i wouldnt mind doing it again to see the difference it has made,

I f i posted the logs on here id appreciate it if Shrak90 or some of the other techies could decipher it for me and let me know how it looked. cos im not going to lie, i have no idea what half of it meant

Email them over to me Si and I'll take a nosey at them.

cheers mate. have you got a work email i can send them to or maybe PM me your private email.

whats become of the code red kit then matey?

gave it a good oiling and service whilst i was at ITG and sold it onto fikes 75 on here. he is running it now i believe. think he wanted it originally when bought off you

this is what i meant about the lips inside the silicone hoses to make the hose seat up against the turbo and Maf housing etc with minimal disturbance of the air.

One of the guys on mk5gti forum has his metal parts of the intake ceramic coated to reduce heat inside. I think maybe a little overkill TBH as heat will go in via the silicone hoses still. but every little helps.

noice

Very nice looks great with superb detail

Well the the guy who runs the mk5 forum had his Revo stage 2+ Golf Edition 30 GTI put on a rolling road with the stock OEM intake for a power run, then the Andy from ITG fiters installed the new intake onto his car without moving the car from the rollers, and they re-tested the car with the new intake on.

Figures on the dyno sheet are in Wheel Horse power not flywheel horse power.

Thats an increase of 43bhp and 15n/m torque over nearly the whole rev range. Now the increases are very large indeeed on this, point to note though is this was not removed from the dyno to remove any posibility of fluctuations in results.

Could you expect this result on your vRS............I doubt it, the edition 30 has a larger turbo so will be able to utilise the intake more than our k03 turbos.

This is also on stage 2+ software meaning that a stage 1 car would not see the same increases. but to be fair a 15bhp+ increase on a stage 1 would be easily achievable. and more would be achievable the more highly tuned your car is.

My initial thoughts were I didnt get that sort of increase but then i havent got a k04 turbo and I didnt have the stock intake on,. I had the code red intake and carbonio fitted before which was an improvment over stock but there was a large difference in air entering the engine after initial fitment, as the car was really hesitant, as the ECU tried to readjust the air fuel ratio, which shows a potentially large increase. The car power band has since smoothed out and is now very linear in its delivery.

I need to go out and give the car the beans to be fair. Which I havent really done it since fitting the intake.

Overall the results do bode well for the ITG intake.

They also tried a different filter on the end of the intake that used touring car spec foam which made an additional 2Bhp.

Heres a link to the other forum with its review and discussion on the dyno.

http://www.mk5golfgti.co.uk/forum/index.php?topic=8495.msg131448#new

As a comparison the evoms gives gains of 8-12bhp, so this makes the ITG a very viable option given the extra 30 quid it costs.

thoughts anyone

well i had my car put on the rollers today to see the difference this intake has made over my previous intake.

Well before I had this Intake fitted, which if I remember correctly as I cant find the Dyno graph for it gave me 7bhp over Stock airbox, pipercross panel filter and Carbon Air scoop whe running Bluefin stage 1@ the time

At AMD essex It ran 277bhp, 305Ibft. Bluefin stage 2+

The red line is the stage2+ plot

Since then this was fitted

And the results are as shown below.

As you can see

I had been giving the car quite a hardworkout on the way there then got caught in traffic and as you can see my first two runs wern't the best as my inlet temps were through the roof. Spo they left it with the fans on the car for a while to cool it down. he the 3rd run as you can see gave me 286bhp 301 Ibft

So 9bhp increase over the previous intake both at stage 2+, and peak torque was down which initially caught me by suprise until i looked and the entire rev range torque spread was slightly higher along 99% of the rev range.

10Ibft more @2500rpm and a flatter plateau of torque between 3000rpm and 5700rpm. and 20Ibft more @6000rpm

What shaun mentioned as well which sounds about right to is that the Heat shield and foam surrounding the intake will block the heat from the engine very well, So the on road increase in comparison to other intakes will be better than an increase seen in the dyno with the bonnet up and a big fan on it where this advantage over other intakes isnt as being utilised.

My inlets temps seem to raise very quickly resulting in heatsoak and loss of power, so i think i defiantely need an intercooler now.

It seem the results could be a little wayward as the ambient temp has been entered wrong. It was 11 degrees according to my car this morning not zero(although after phoning them up they reckon it was entered in correctly and its their new dyno program that has been causing issues...he did mention issues beforeso wh knows....?)

I have been offered this intake for £250 from Angel Tuning (normal rrp £345ish) if you are a previous customer I think the offer applys!

wrong info

mate, that is what i paid, and believe me it is very very worth while doing it.

I definitely would have if not for the small matter of a complete Evoms kit (including engine cover) 1 year old covered 10k for a messily 180 sheets delivered.

TBH, and you’re going to hate me, but in terms of looks, I think your Code Red was the mutts nuts, but I think the ITG is a bit ugly but in terms of performance its phenomenal.

What other work have you done for stage 2+, mines had the stage 1 remap and the Evoms imminently, as I understand it, a 3" downpipe will effectively take me to stage 2?? Although after speaking to Angel Tuning (the remappers) they said the addition of the CAI doesn't require a software upgrade?! :confused:

I only bought the code red on looks, up close the ITG looks better when you see the attention to detail on it. its undoubtably performance over form though in comparison.

to be fair the TFSI engine as a whole is a very ugly engine with the engine cover off, still who drives with the bonnet up, lol.

my spec is as per my signature below. I do however need an intercooler as my inlet temps sky rocket when im in traffic. looking into getting water methanol injection though before that which should cure it a little as well as giving a very nice performance gain.

just waiting for quotes back on fitment etc.

with your car @stage 1 the CAI wont need the map adjusting , whereas when you have your stage 2 map installed they can adapt it to make best use of what you have
