I'm selling mine (I know its standard so not quite comparable to your 300bhp beast any more) and have put everything back to standard ready to sell, and I have to say, I think it is much more responsive with the factory airbox back on.

Low down in the revs the standard box should be able to flow plenty enough for a standard or mapped engine, so if you are only doing short journeys you may well be better of going back to standard intake...Once the engine is up to speed I wouldn't be suprised if the standard box is too restrictive for your engine and you may well notice it loosing you power though...

I had a twin cold air feed and the air filter always felt cold after spirited driving

Not so much an update, but more of a 'Should I or should I not?' post sorry!

So, been noticing with the gradual increase in temps, that the car is feeling progressively more laggy lower down day by day almost. I'm putting this down to the Jetex cone as I've not felt this so much before.

I'm tempted to stick the OEM airbox and Pipercross panel filter back in this week to see if it makes a difference. If it does, I'll have the jetex/jabba setup for the winter months only.

I just find with the short journeys to the gf's etc where the car doesn't get to stretch it's legs, that the lag will get worse and worse as the temps go up over the coming months.

Has anyone else found this with their Jetex setups? Would be interested to hear from you guys and how you've found the rise in temps and and 'lag' feel lower down in your LCR's.

Mines felt a bit more laggy lately but I thought that was down to the map not being quite right at the moment. Hope its not this as I dont have an airbox lol

 

[t0m]

Yeah my car did not get on with the jetex cone filter for some reason i noticed the temp went up when running with it and besides my car threw a wobbly with it, so i have resorted back to the standard airbox with a green cotton pannel filter running a cold air feed to it where the old intercoolers used to sit, seems much better now i personally believe closed induction is better but each to their own, noise was good though with the jetex ideally you need to run with a heat sheild i know jabbasport sell one, but mine was deffo running rough at the time

I've got a Jabba shield on mine that's the thing, but I think even ambient temps of around 10 degrees are starting to see the open cone's become laggy. And I don't like it! I won't be running a cold air feed to the airbox, but I'll more than likely be putting my airbox back in soon to trial it anyway.

Its interesting you say that. I originally put my cone filter on in September and wasnt impressed due to 'lag', two weeks later it was removed. I put it back on at the start of Feb having had the airbox off to check out the DSG intake for another member, I loved it straight away. Maybes its due to the cold temps outside! If you do change back I'll be interested in your findings. Also I think you do get a bit extra torque lower down with the box, if your not getting to stretch its legs then maybes you would be better off with this setup!

Yeah I think Feb was alot colder than this current time in March matey. But even so I think they are always going to be a bit more laggy. I'm just thinking if it's this laggy at around 10-12 degrees where I am now, what's it going to be like in June!?
I think I will put the panel filter back on soon and I'll let you know how the car feels then. At the moment it's just low down it feels sluggish and not responsive enough.

You know what I think Tom, Modded airbox all day long

I know Daz, I know!!
I might trawl through your guide and mod my airbox if I'm impressed once it goes back on. You could carbon wrap the airbox for me

I'm selling mine (I know its standard so not quite comparable to your 300bhp beast any more) and have put everything back to standard ready to sell, and I have to say, I think it is much more responsive with the factory airbox back on.

That's exactly what I'm thinking, that I might lose a bit top end.. But I'm asking myself how often do I use that, and it's not as much as I'd like!! Small trips to the girlfriends or my mates etc the car barely warms up let alone stretch it's legs! I'm very funny about putting my foot down after just starting the car. I'll always leave it 20mins or more no matter what until the turbo has really warmed up enough.

I'm expecting it to feel more responsive with the airbox back on, so I'm hopefully going to get it done this week and will let you all know how I feel about the car then.

I had a twin cold air feed and the air filter always felt cold after spirited driving

Mine does too mate, and that's with no air feed. But it doesn't stop the early initial low-down lag in the LCR's
Air feeds are useful once your on the move but short journeys and low speeds they don't do much to reduce lag from induction systems I think.

Mines felt a bit more laggy lately but I thought that was down to the map not being quite right at the moment. Hope its not this as I dont have an airbox lol

Lol, have you binned your airbox then mate? I need to check where mine is actually today, I think it's in the loft with the Pipercross filter still inside!

 

[coops10]

The car came with a closed cone on it so never had an airbox

 

[turbo009]

I'm seeing how my Jetex runs if not I'm switching back also to standard air box

 

[tom0311]

Mine felt more laggy and sluggish low down as soon as I fitted it, and I'm not even mapped yet. Not sure how it's improved anything apart from the nice noise to be honest!

 

[RDS]

I got gains of 4g/s mass air flow with a cone over the air box! thats without a cold air feed or heat shield. Once I get the FMIC fitted I'll be running a twin cold air feed from the fog lights.

 

[jonjay]

A thought Tom.

The intercooler may not be as efficient now the weather is warming up. You should compare your intake temps to someone who has a forge to see if there are differences.

I was going to get a forge intercooler before i sold the car, as its proved that as good as non forge intercoolers are when moving and keeping things cool, the forge ones deal better with the heat and recovers quicker from heatsoak!

Compare it to mine if you know what to log

 

[tyrer]

Airbox all day, unless you live in Germany on an Autobahn or a drag strip low down torque is needed more than anything 'top end'.

That's why eventually I'll upgrade my Revo to the 'linear map' as I'd rather have a consistent power band over the kick of turbo.

I was told by a race prep tuner 2 years ago this - "they don't spend all that money developing the intake system for a big cone to be better in everyday driving conditions, find the small restrictions (smoothing or non tapered inlets) and get rid of them before any cone"

Must say he was right.

Oh, lol

I had my 1st Jetex on before it was mapped and it felt the same then tbh mate. I think tbh they will always feel more laggy than panel filters. I should have time on Friday to re-fit my panel filter and see how it feels then. If it drops to 280bhp that's enough for me

I got gains of 4g/s mass air flow with a cone over the air box! thats without a cold air feed or heat shield. Once I get the FMIC fitted I'll be running a twin cold air feed from the fog lights.

I gained g/s with the jetex, but I'd rather it feel better around town at the moment for the driving it gets used for. I dislike low down lag more with the warmer temps. Today it hit 18 degrees where I am which is a far thing from 0 degrees of 2 months ago, if that.

Look forward to seeing your twin cold air feed setup when you get an FMIC bud.

A thought Tom.

True Maz, and a valid point. However last year we logged the car in August when the FMIC went on and it showed intake temps of 10-15 degrees tops over 4 4th gear runs on a nice stretch of road

The SMIC's we're showing upto 30 degrees over the same runs!! Mad difference that the FMIC's can make. But I would like to compare to a Forge jobbie if possible.

Shaun at AmD said my FMIC was good and doing a great job when it was mapped and then the recent rolling road runs of 283bhp and 300bhp. But low down of course is another story with the core being efficient at those levels.

I was going to get a forge intercooler before i sold the car, as its proved that as good as non forge intercoolers are when moving and keeping things cool, the forge ones deal better with the heat and recovers quicker from heatsoak!

If that's true I will be a bit upset, lol. I like my TX, but of course the Forge has supreme R&D put into it so I'd expect it to be capable at any speed. When I get my vagcom working (possibly tonight, finally got a laptop to trial out my version and a light version) I will do some logs once more hopefully before the panel filter goes on too.

Compare it to mine if you know what to log

Cheers Daz. I might want to yet if I can sort the vagcom as above post

Tend to agree mate. If I am happy with the panel filter and it cures this laggy-ness, I will smooth the airbox as per Daz's guide I think. Maybe get a dremmel on it and see what I can do.
I've already got the Pipercross panel filter which is in great condition so that can be used once more.

 

[D.K]

All the Seat Cupra race cars ran the OE airboxs aswell

hmmm
and they made such a nice job of the intake pipe too
superb engineering there...

Sorry, I dont subscribe to that logic

They make mass produced cars to a price, end of

 

[ibizacupra]

and yet, you can achieve higher airflows across the board with a larger surface area filter..
heat shield a cone and get the best of both worlds

these are also the same "race" teams, who had to use clamp covers to hold down the coil packs, where a simple cut slot in the coil achieved the same thing.

 

[Murdered LCR]

Haha bill glad you have had your say in this , air boxes are good for one thing only and that's the bin , cone filters are alot better than the air box

Oh I agree Bill as I said stuff needs changing i.e. intake pipe (I said inlet???) but for everyday I still think it is the better option.

People can post data but if you are not happy regardless of whether it's in your head then it's down to each individual.

I'm just a Airbox fan tis all hate open cones unless I owned something to race.

Gotta say I agree with this. Everyones different. If your car feels better with the airbox then who are we to say otherwise. hope you find a setup your happy with mate!

 

[t0m]

Cheers for the replies guys. Always open to either side of the arguement and Bill certainly has a point.

I believe from what I've had on dyno runs, the open cone jetex to without a doubt give more flow than a panel even uprated, drilled what have you. But my car is feeling laggy low down. All I'm doing is fitting the airbox to see what this feels like, as the car was never mapped on the OE airbox. I would just like to see how it feels with that on now it's running some good power/torque...

However see below update post from tonight's vagcom play with a friend of mine...
