colly Posted April 21, 2006 Report Share Posted April 21, 2006 right i know the universal inductions slurp a bit more. but do the proper ones for the car use a bit more? i know that they will allow more air, in so the engine management system will let a bit more fuel in to make the mixture right, but have you noticed a decrease in your mpg? thanks colly Quote Link to comment Share on other sites More sharing options...

T-BAD Posted April 21, 2006 Report Share Posted April 21, 2006 try here >K+N FILTERS< i thort it gave a richer fuel intake? something like that allowing your car to run more efficiantly and perform better?? correct me if i'm wrong Quote Link to comment Share on other sites More sharing options...

bikerdude2006fr Posted April 21, 2006 Report Share Posted April 21, 2006 Wouldnt the more air being intook case the like combustion to be more powerfull therefore creating more umph without more fuel?? Quote Link to comment Share on other sites More sharing options...
Lee Cable Posted April 21, 2006 Report Share Posted April 21, 2006 I know when i put one on my moped, i had to get new jets (in the carb) for the bike, as the mixture screw wasnt allowing my bike to start. just fit it, twiddle around wid mixture screw and see if works, if not, get new jets!From Lee Quote Link to comment Share on other sites More sharing options...

JTM Posted April 21, 2006 Report Share Posted April 21, 2006 The only increase in fuel consumption will be down to you booting it more to hear it sucking in small children. What car is it? 9/10 times a panel filter is better i you want to increase performance as an induction kit will be plagued with heat soak Quote Link to comment Share on other sites More sharing options...
Caleb Posted April 21, 2006 Report Share Posted April 21, 2006 plus panel filters are cheap as chips too, i got a pipercross one on ebay for like £4 purely cause my standard one was fudged . Quote Link to comment Share on other sites More sharing options...
colly Posted April 21, 2006 Author Report Share Posted April 21, 2006 its a 1.4 corsa sport, its going to get 2 big pipes from the wheel arch taking in cold air, i no engines run best on cold air, but when the engine is cold and they breathing cold air they use lots more juice. they definatly wont run richer because more = a weaker mix of petrol, suppose the only thing i can do is put the air box on and see if theres any difference personnaly on me old sri, the origianl deristricted air box made it go lots better than an induction kit Quote Link to comment Share on other sites More sharing options...
PaRtZ Posted April 21, 2006 Report Share Posted April 21, 2006 Wouldnt the more air being intook case the like combustion to be more powerfull therefore creating more umph without more fuel??Ker-ching!With the limited knowledge I have, you can have air filters which don't cool the air, and air filters which do cool the air. Basically the cooler air filters mean that the gas is slightly more compressed so you can get more air inside the engine thus making it more efficient. As said above though, this can be overdone though... but my mates have K&N air filters and it sounds much beefier Quote Link to comment Share on other sites More sharing options...

trials_pimp Posted April 21, 2006 Report Share Posted April 21, 2006 Right now the clueless and google bound "heros"have been, I shall explain.The effect of an Induction kit, no matter what make, will have a different effect on differnt vehicles.You have to take into account what system fuels the car.IE: If you are running with a carb, it will give you a lean mixture at idle, and can increase fuel consumption through the rev range, as the intake of air is less restricted.If you are running MFi you may also find an increase in fuel cosumption due to more air entering the fuel metering head.If you are running EFi it would depend entriely on the system used. As differnt managment systems will react in a differnt way. This next bit is RULEThere is mo such thing as bolt on power. You WILL NOT recive a big power gain from simply fitting a Filter, or exhaust.Most mods are usless unless they are done in connection with other mods to enhance them.IE: there is no point getting more air in, if you cant get it out fast enough Quote Link to comment Share on other sites More sharing options...
Trials Punk Posted April 21, 2006 Report Share Posted April 21, 2006 Another point. If you put too much cold air through a carb, you'll get what is known as carb freeze. Which belive me does not improve the performance of that engine.For carb its usually best to get a filter sitting at the back of the engine away from serious heat and cold.

Prawny Baby Posted April 21, 2006 Report Share Posted April 21, 2006 its been questioned how much difference it makes running pipes from inside the arches to get a cold air feed....a mate of mine set up some electrical kit under his mini bonnet to check this out, and he found that above 15mph the temperature at the back of the engine bay (where the air intake is on a mini) was no different to the external temperature, proving that it is utterly pointless on a mini, unless your after a ram air effect like they have on miglias, which will only REALLY come into play at very high speeds....if you have EFI, it will generally compensate for the filter by fueling it slightly more, as the lambda sensor will detect that it is running leaner, so in thoery, an increase could occur, but as lee said, you need to get it out as well!on a carbed car, itll just lean it off, as there is nothing to actually increase fueling in accordance, so it would need to be setup on a rolling road to get the best results.personally, we run K&N replacement panel filters in our cars (audi 1.9tdi's) and tehy do appear to give a much more lively and responsive engine, although i highly doubt ultimate power is any different.on my mini i run a K&N cone, and the noise it makes is gorgeous, although id hate that kinda noise on a slower car, theres really no point in having the noise if its not got the pace to match, so just stick a K&N replacement panel filter in and be happy theyre dead cheap on ebay!

pinky Posted April 22, 2006 Report Share Posted April 22, 2006 I have K & N on the polo it does sound pretty awesome, I was told it used more fuel because of the increase of the airflow, Who cares it sounds good Quote Link to comment Share on other sites More sharing options...
RyanRs Posted April 22, 2006 Report Share Posted April 22, 2006 (edited) K&N WILL make your car more juicy because the car has to keep a certain Ratio between fuel and air.. the mix has to be rite for the car to work properly/safely.The ecu will detect an increase in airflow/density and alter the ecu map to keep the fueling ratio the same. if you have a carb, then you will need to get it Rolling roaded so as it can be mechanically set up. not doing this will make your car slower than not having a k&n (by fractional ammounts -but cos of the added noise, it makes the car sound faster and gives a false illusion, so people think its actually got faster when it hasnt!)if you fit a K&N and dont alter the fuel mix, the car will run lean, making the conbustion temps increase, giving a poorer conbustion, higher engine running temps, and can cause Pinking / detonation.. which is where the fuel mix in the combustion chamber detonates due to the increased temp, before the spark plug sparks, causing a massive drain in power and possible engine failure in serious cases!so if you want a k&n , u will spend more on petrol and if you have carbs , get it set up properly.

trials_pimp Posted April 22, 2006 Report Share Posted April 22, 2006 Ryan, you dont seem to have a clue really.Pinking and detonation are 2 completly differnt things.Air/fuel ratio has nothing to do with safetyAs for your map theory, that would only happen on the latest most advanced systems.Most electronic injection systems run on a base map, and will stick to it with only minor alterations.A system such as L-jetronic wouldnt alter the map in the slightest.You dont really need to rolling road a Carb fed car if a air filter is the only mod, as it will only run lean on idle.And there is no way in hell that a filter would lean the fueling off enough to cause any damage, let alone detination.

Prawny Baby Posted April 22, 2006 Report Share Posted April 22, 2006 A system such as L-jetronic wouldnt alter the map in the slightest.wasnt that the system used on the XR3i back in the 80's? made by bosch?PERSONALLY, for the noise increase you get, id never fit a Cone type filter or induction kit to an every day road car with a small engine, as the performance gain is so pathetic compared to the noise increase, its jsut not worth it! just use a K&N replacement element.however, if i were to stick the standard metro airbox and filter ontop of my 1380, i could imagine id get a serious drop in performance, although the imense noise from the engine itself and the straight cut gears would still deafen me.....lee- i seem to recall you saying you were going to run megajolt on your new motor in the capri?are you planning on having a fiddle with the maps yourself on a laptop? ive got a few maps for various mini engines of various states of tune. ill be fitting megajolt either this winter to my current 5port motor, or next year when i get the 16v head.im tempted to run the serial cable inside the car, and have a fiddle myself and have a few different maps to load up for different types of use!whats it cost to setup megajolt on a ford engine? im imagining its pretty cheap, seeing as it uses the ford EDIS coil pack and the std ford 36-1 trigger wheel.....to run it on a mini you need to have the crank damper machined, or find a way of attatching a sierra trigger wheel onto it Quote Link to comment Share on other sites More sharing options...
MadManMike Posted April 22, 2006 Report Share Posted April 22, 2006 Plus there's the fact that K&N are just overpriced versions of decent filters...Ooh, let's whack an extra £40 on top because it has a chrome K&N top... woo! Quote Link to comment Share on other sites More sharing options...
trials_pimp Posted April 22, 2006 Report Share Posted April 22, 2006 Prawn.Yea ive got a megajolt kit for my Zetec.I will be mapping it myself when its fitted, using a laptop. But 1st Ill have to learn how to write maps. I dont think its that hard.I will be easyer to instal, as you say, as I have the 36-1 built into the flywheel, and the coil pack from the original running gear.I have also got a Front mount trigger wheel that came with the kit, this is surplus to my needs, so if its of any use to you.....As for L-jetronic. The mk3 XR3i had K-Jetronic, mechanical Injection.L is the next system that is more electronicly run, but still has mechanical elements.
