ITG Pics and opinions please

[Leonneke]

Well hello all Seat guy's;

First of all. Very much thanks for all the reply's. As far as the surge is concerned, here is a very good example of what surge is .......... Look at the film completly. When the car is driving, you can exactly hear and discover what my car does. This is NOT a normal reaction. This is SURGE. It is caused by a physic problem in the diverter-valve system. Could be the capacity of the diverter, to weak spiral or whatever. If you hear this sound on your car, your turbo can NOT get rid of the overpressure.
This form of surge is less harmfull to you motor. If you hear this sound when stepping on the gas, it is really killing for the turbo. Then overpressure hits the compressor wheel. NOT GOOD.

I have the most problems when coming off the gas. But sometimes with full load, I hear surge to.
This problem will be solved by the tuner in short time. I am really sure that there is more pressure and faster spool. The surge gives the answer to that. Much more pressure, but cannot get rid of it.

Look at this and turn on the speakers ............ SURGE

well keep us updated on your findings, but none of the tuners in England seem to be concerned over what you call the surge!

Just listened to the vid above, but that flutter is a pretty common feature on most turbod cars, ours, scoobies, evos, supras etc

suprsied there is no heat shielding though, so the car will be getting lung fulls oh hot engine air.

Well okay, I can understand your quote. But really, did you test the temperature behind the fog light ?? It is NOT hot in that part of the car. And have you seen the heat-shields that were built by ITG. They only form a shield between the motor and the intake opening.

But just to find out, UNDER the intake opening, or just nearby, you can see a big black hose coming from the IC. Put your hand on that hose. It is really HOT.
And the opening of the intake is very, very near to that hose.

I will make a heatshield myself. But not just one that is between the motor and the filter.
The real hot air is just under the filter and the very first hose.

What I will do also, is RE-USE the original OEM intake hole.
a lot of cold air is coming through the original hole ....... I will make a connection to that hole and lead a hose to the filter itself ....

So I will surely make sure, that the filter is shielded propably. And also gets cold air from two sides. The heatshield developed bij ITG and all the other ones are not good enough.

So don't worry about that. My worry is the surge. I think my tuner / engineer will install a Synapse Synchronic Blow Off .... Pressure in and pressure out have to be in order ..

that is to the left of the heat shield on the ITG, and doesnt seem to have an effect on the filter at all.

have i seen the ITG heat shield i have one on my car.

the air coming in from the fog light will be the ouside ambient temp and creates a high pressure area around the filter which is good for the performance of the filter and also will reduce hot engine air getting through to the filter.

you can see the top right of the pic the hole above the inlets next to the fog lights

The cold air coming in from the slam panel will be hitting straiht into the right angle silicone pipe, negating the effects of the hot intercooler pipe

you can see the flter following he lines of the bonnet as well

im interested to know the reasons it is not up to the job

So I will surely make sure, that the filter is shielded propably. And also gets cold air from two sides. The heatshield developed by ITG and all the other ones are not good enough.

you most certainly havent seen the ITG. and reference cold air from both sides, you will still get ab influx of cold air coming to the left of the filter through slam panel opening and grill.

here is the BDM intake for comparison. that filter is HUUUge in comparison thuogh, so i would epect gains to be good, especially if you have cold air feeds going to it

Hello vRSy, sorry I don't know your name. You have totally convinced me with your support. So thank you for the very good explanation. BDM was willing to make an shield, but could not manage that in time ( I wanted the kit as soon as possible ).

I will make the heatshield myself ( I mean someone who can work with alu ).
The material that is used against the ALU is sold in Holland also. It is manufactured by Merford Noise Control. It is thermic and noise reducting ( mostly thermic )

It will not be to hard to make a shield like this. But just one question if you don't mind me asking. Is the ALU connected to the car with a screw or something ???

The rest of the BDM kit is the same. Heatshield near the MAF housing. Very good. Fits very good on the two 'pops' and rubbers.

As far as the surge is concerned, this is the kind of surge that is less hard for the turbo.
But what you hear is air bouncing the compressor wheel. I surely want to get rid of that surge. It is okay with me that tuners in England do not find this interesting.

My tuner in Holland surely does ( JD Engineering ) .... If you try to make more power, also these kind of things should be correct. The overpressure should NOT ga back to the turbo wheel. It should be blown off or diverted. You want your turbo to spool up faster.
Than WHY should you let the overpressure brake it down ?????

I really hate that sound. Air that is boxing with its self. Just want WOOAAHH and WOOOSHH ....

 

[vRSy]

the aluminium sheet, is glued to the foam heat shield with some resin. it is merely there to provide rigidity to the heat shield.

i believe the entire intake is the exact same as the ITG, except for the final rightangle bend(which is shorter) and the filter/heat shield.

I reckon if you can successfully shield the filter and create a high pressure area around the filter it (ignoring the possible variations in filter material) i reckon you should out perform the ITG due to the shear size of the intake

Just to save you wasting your time when i was speaking to Andy@ITG (the guy who developed the intake) the oem intake flow is crap and your better off running a hose from the lower fog light area to the intake and IMO after a long drive the area around the intake is nice and cool and i dont think the heatshield is that bad really.

Get some vids up of the BDM intake mate

Get some vids up of the BDM intake mate

Well hello Rob: You have to explain to me what 'vids' are ? You mean pics or do you mean results of a dynorun ....
By the way, my car wil be remapped on 02 februari !!!!
And a high pressure fuel pump will be installed. At this moment, or better, with the OEM intake, it was tuned to 333,4 horsepower and 445 Nm ...

Think that you Englisch people have different value's ???But I will post the mapping diagram in this topic. Thanks for all the tips so far.

By vids he means videos. 333hp with just map and nothing else?

Nope, that would be to good to be true.
Full Miltek ( downpipe and sportscat ) and 'individual' Software/Chip by J.D. Engineering.
Untill now I used the Carbon Intake. Only the box, rest was OEM. The Carbon box made a difference of 5 hp. ( measured ).

My car was original a 310 Limited Edition with ABT software. Untill we found out, that the car was not mapped at all by ABT. The dealer had 'forgotten' to shoot the software in.
So therefor, I got the 'individual' software.

This tuesday, a HPFP wil be installed. The car will get a remap by JD ... Keep you updated.

ok cool.

Rolling road today...I'll post reults later. It might push me into getting onw of the above...

What results did you get mate?

 

[robjnr]

Leonneke get some sound clips up of the BDM intake, i need to here it!

 

[deann]

What results did you get mate?

Not great only 252 HP and 210 FtLb But i'm running a forge spacer and i dont think that helps...Also got them to run a VAG COM?? and it high lighted

Fault 008801 - Boost Pressre control valve N249 Mechanical malfunction???

So it's now booked in to Seat on Monday..

Can you not just bypass the N249?? know you can do it on the MKI and the beezers with some good results

 

[deann]

what is the N249?? what do you do to bypass it?? thank you for the reply.

 

[chrisboyle999]

n249 is a turbo recirc valve. it reduces lag by keeping the turbo spooling.
i wouldnt bypass it on a new car.
