Induction kit?

fonecrusher1

Should i bother throwing a performance induction kit on my boring 2000 1.4 corolla?

For the laugh!!!:D

Can't afford a fancy exhaust. Factory air filter assembly looks sh!t, like its strangling the engine.

No! You can actually slow it down due to heatsoak...

If you want to increase performance this way, think about getting an aftermarket panel filter, and remove the resonator from the airbox.

9 and a half times out of 10 the factory cold air feed is the best you can get for your car.

Hmm?....im interested. Please explain more.

There is much speculation on the internet as to wether induction kits do anything for a cars performance.

I know a wee bit about cars but nothing about performance upgrades.

Well, normally induction kits in cars are big open filters, this allows hot air to be drawn into the engine (from the engine itself being hot), hotter air as you know is less dense than cold air so your actually reducing the oxygen entering the intake manifold.

Secondly, by allowing too much air into the engine without the proper mapping can reduce torque.

A performance panel filter drops in, in place of your OEM one and allows a little more air in, while preventing heatsoak.

I'l head into the local auto performance accessory store tomorrow & have a look at the k&n/pipercross air filters.

If you get any extra power I would be surpised... more noise yes.

A decent service and new set of plugs are probably more worth while!

Already done both myself.:D

Well even if it only improved the corolla's wimpy engine tone it would be worth it.:p

Okay... decent oil (correct level)


..tyre pressures?

is it injection?

Oil is 3 weeks old & dipstick shows oil-level to be at correct distance between min & max marks.

Corrected tyre pressure last week on all wheels to 32psi.

Its the vvti 1.4. Nippy enough car, just a sh!t sh!t sound off it.

Theres nothing wrong with it, tiz more my boredom more than anything.:D

I was thinking you could trick the injection for more power... I have seen this on other cars... just tricking the car in to thinking the engine isn't warm and it delivers more fuel... not clever buy like I say, seen in a few cars.. only good for a few bhp though!

How about replicing one of the silencers with a straight pipe? keep the noise low though you don't want to attract the guards... unless they are lasses!

How much would that cost? What about a decent backbox?

She's nct'd for nearly 2 years so i wouldn't have to worry about sticking stuff back on the exhaust system for the test.

Only female guards ive ever encountered were howlers.:D

Definitely not true for turbo diesels, factory cold air feeds are a balance of power, noise and reliability with power often being the lowest priority.

A decat would actually gain you a couple of BHP, and the car would be louder as a result...

put some more sound deadening in.

1.4 Corolla won't ever be a performance car, and starting down the modding route will harm it's future value.

If you want something zippier buy a car with a bigger engine.

Donal199

in some cars you can buy piping for an induction kit so you can extend 2 sit right behind the front bumper, this would mean that the heat off the engine isnt being sucked in, not sure if theres room to do that in corollas tho, it wil still give F all power gains but u wil get a nice throaty sound in the high revs

Never said i wanted a performance car (previously owned a legacy B4!;)) or a zippier car or a car with a bigger engine.:)

The car just has a very droll engine noise when accelerating, its normal for these corollas, parents had same car years ago & i remember the lifeless weezing noise the engine made.:D

Once owned a civic coupe that already had an induction kit installed when i bought it & there was a nice old snort off it. I took off the kit before i sold her on & the engine note wasn't half as nice.
Thought i might be able to achieve the same result for my current car but it does seem its not advised for this model.

Might get something exhaust related soon.

If its just noise you want and you dont care about losing a bit of power then an induction kit is exactly what your after.

djimi

No offense but noise for the sake of noise is a bit sad.

Buy some nice cd's then? They'll surely drown out the drollness.

Nah. Not gonna bother if the kit actually decreases power.

Surely if i can get the upgraded air filter positioned as far forward as possible it won't ingest hot engine air? (as donal199 said)

It's far away enough from the engine to avoid the hot air as well.

The hot air will build up in the Engine bay anyway and be sucked in.

Upgrade your panel filter and then put a cold air feed from your front bumper to the box. Just be wary of puddles if you do this.

None taken.

No offence but i don't really value or care for your opinion.

Its just a bit of harmless banter with people who do actually know about cars.;)

Well heres whats under the bonnet. Looks very tight for any sort of induction kit!?:eek:

You should be able to find a kit for it, but I can't say it's going to help any.

Who'd put an induction kit on a Diesel?

Factory cold air feeds are a balance of getting the right amount of air to match your fueling,true there are concessions made on all cars to make them more reliable in all conditions,but these concessions are made internally via trubo boost pressures etc not via the size of the cold air feed.

Take the mk4 golf TDI for example,the factory cold air feed on that car is more than adequate for the job it consists of feed from the front grill into a sizable airbox and an 80mm MAF housing,you will get ZERO performance gain from fitting an induction kit.

challengemaster

Relocate the battery to the boot, that'll leave space for the induction kit.

Make a custom heat shield, pop in the induction kit..shouldn't be sucking in too much warm air. Also, if there's no fogs on the car you can put in some piping to direct air from the outside of the car towards the filter.

While people are saying you'll lose power, you're talking 3-5bhp... not like it's gonna half the cars power.

I wasn't talking about an induction kit, I was talking about changing the cold air feed.

One of the most common ways manufacturers use to restrict performance on a turbo diesel is to deliberately restrict the airflow and/or the turbo.
And yes, many manufacturers do deliberately restrict performance to a set level.

Take for example the MG ZT CDTi, it's air intake was designed to restrict airflow(especially above 3000rpm) so as not to compete with the BMW 320D for power output.

In fact, it stifles power so much that if you just cut off the intake at the engine cover so it draws in the hot air from the engine, you still get a significant power increase.

So yeah, sorry, you're wrong.

Lads would a k&n filter that fits in the existing airbox make absolutely any difference to performance or the engine noise?

Anybody here with a performance air filter in their car?

Donal199

It would make it nosier in the higher revs but wouldnt noticably increase or decrease performance

I have a K&N highflow panel filter in the factory air box on my motor.. performance wise id say its nothing to write home about.. But yeah gives a nice sound..
Its not a loud knacker big bore exhaust sound.. just a nice sound!!

Tossy I know you like your motors so I can't believe you're serious?
So you're saying that for example this induction kit...
http://www.awesome-gti.co.uk/product.php?xProd=14101&xSec=1
for the VAG 2.0TFSI doesn't give performance gains? or the Code Red? or the EVOMS? or the K&N?

I know I'm only giving an example of one engine (in many models of car) but what I'd say to the OP is.....for your car there would be no benefit in performance for fitting an induction kit. It may even reduce performance of it and could reduce the resale value of the car.
....I wouldn't be writing off all induction kits

Yes im saying that,the performance gain from that kit would be very little compared to factory feed,in fact if you are going to fit an induction kit like that you need to go all out and have the cone fitted in the lower bumper(i actually have one despite my rantings lol),where it can act as a true cold air feed.

Take that kit for example,its located in the engine bay,even though there is a shield on it the air temp in there is still going to be higher,plus any gain in extra cold air being brought in is negated by the air being super heated passing through the turbo,you would need a FMIC to cancel that effect out.

These claims of BHP increases from Induction kits simply can't be believed and have to be taken at face value,the best you can hope for is an engine that breathes better (from a lower bumper cold air feed) and and engine that is more responsive across the rev band.

As some one said you are better off fitting a K&N or ITG panel filter in your existing airbox.

Just my 2 cents.

A cold air feed is simply a cold air feed, it's in the words mange.

A cold air induction kit is a cold air induction kit, a cold air feed isn't a cold air induction kit(but it's usually part and parcel of it too).

@si_guru.
Do you own an MG ZT/R75? Have you driven one? Have you talked to the people who helped develop and test it? Have you modified them, taken them on dyno's and spent hundreds of hours tinkering on them? Have you compared results with other people who do the same?

Nah, didn't think so. Eejit!

Nah, of course not

You also contradicted yourself, what happened to a cold air feed being an induction kit, when in your first post you said all cars have a cold air feed?

As I recall, I just said eejit. One out of about 30 words when replying to someone who said nothing but 'cough bs cough'. You don't seem to be making all that much sense so far tossy.

Tbh, I actually didn't ever really disagree with you. You were talking about petrols, I was talking about turbo dervs. I'd say most of the cars that people buy induction kits for don't have intercoolers, in which case it's a big mistake.

If you do have an intercooler, generally getting enough air for the fuel mix is a bigger problem than how cold that air(hence why diesel smoke on full throttle on most of them).
