Cold air feed

[Asha]

This is my induction kit on my mk1 LCR -


I'm not sure/happy with the cold air feed. It's still using the OE air feed from behind the grill but as you can see there's an 80mm air ducting pipe from behind the light to the filter.
Is there a better way of getting cold air to the filter, as I don't think it's getting enough when pulling off.
Other than putting the battery in the boot to get the filter closer to the front grill, what can I do?

How do you know its not getting enough? Have you logged? What power figures is your car making?

Is that other cold air feed right up against the filter? My RamAir filter came with a feed but the instructions said not to have it less than 10cm away from the filter. I think if you moved it away a bit the filter would have quite a good supply of air tbh

No mate I haven't logged it as such, I just dont think it's getting as much as it could.

Ok mate cheers I'll move it back and see if that helps.

Is there anything mod wise I can get that would deliver the cold air to the Filter better. The OE just doesn't seem very good IMO

When you're not moving the feeds probably do very little but when you're going along there's a lot of air passing over and through the car. Buy a couple of little thermometers and put one by each feed or by the cone itself and go for a blast. I'll bet the temps are low when you check afterwards.

Measure and you will know, you are guessing at the moment. Do a VCDS/vagcom log and incorporate the MAF values. You can then make an estimate how much power its making.

The filter gets a lot of air just by driving (air underneath the bonnet), without the feed.

I dont have a heatshield and/or feed and my airfilter wasnt the restrictive part on my build (Blox Velocity Stack open filter), the turbo is (k03s).

 

[Asha]

Thankfully mines a k04 which is better than the k03 from what I'm told. I have an odb2 reader and torque app, how accurate are they, do you know?

 

[nd-photo.nl]

Yes k04 is better They are accurate as they read out the sensors of the car.

I went for a very spirited drive just and this was the result via torque app


It shows I was boosting at 2.4 bar, which I find hard to believe as my cars not mapped, too my knowledge.
The MAF was reading 179 g/s.
HP 177.8 which I hope to god isn't right.
Air intake temp was 12 degrees C.

I have no idea if any of it is right or any good "/

That boost looks a bit high...

Is your car standard? 179g/s should be somewhere around 223BHP. Check for boost leaks, might be its compensating for boost leaks.

 

[Asha]

Ok mate cheers. I'll have a look into that

Best solution is to use the standard air box .......... cut all the fins off the inside and smooth it out nice with wet and dry . Rip the tiny cold feed pipe off and enlarge the hole to 3 or 4" . Run a pipe from the new hole (glue it in with silicone ) to down below the fog light area ( go to head light , turn sharp left and down hill through the hole !) On the intake end put on a ram air collector and fasten behind grill ( demon tweeks motor sport cataloque ) cool Ram Air is worth about 15hp at 100 mph .
Job sorted .
Oh you can stick your orange cony thing in the air box if you like but stock paper filter gives better results

 

[Asha]

I don't have the standard air box as I bought the car with an ITG enclosed kit. My guess is, it'd cost a lot to put it back to standard

yeh try looking for the std air box as well nothing massively wrong with it and your bosting a 2.4 bar...that's loads,im sure std your be looking at 11/12 psi(just under a bar)on the ko3s turbo,the k04 might be the same of bit more??
by the way, forget your cold air feed you want to fit a strut brace,not sure how you can tell the different in how much of a cold air feed your getting but the brace you will notice straight away

 

[Asha]

Before I put the heat shield on the torque app was showing my intake temp was 19 degees C and now its 12 which is good. I also moved the cold air feed pipe away from the filter and it has made a difference I think. I'll take another log later on today. I have also ordered a psi/bar gauge and bought some pipe yesterday as I'm making a DIY boost leak tester.

How would the strut brace help with my air feed?

It wont, hes just referencing to it as a worthwile upgrade.

I did think that but wasn't sure what relevance it had to this thread lol.
As it happens I am looking for an upper strut brace
