Induction Kit!

[SRi_James]

I've seen many examples of induction kits that actually DECREASE efficiency due to bad design sometimes, but mainly due to the fact that car manufacturers have become much more savvy about air flow these days!

thats y im makin a modified air box with performance pannel filter (piper x) for my bro, coz lookin at his T - Sport engine bay, i thought an induction kit would suffer from too much hot air from the engine!!!

James is ur Corsa a 1.4? If it is u should get a Pipercross Cossie induction kit cos my mate has 1 on his Corsa 1.4 sport and it sounds the nuts!!!

yea i av a x14xe engine (1.4 16v)... with a piper x induction kit it sounds the dogs! :D

i know a few ppl with the cossie induction kit on their 1.2 16v corsas! lol (still sounds good!) but tbh they r ott and obsorb too much heat! they only just fit in the corsa engin bay (with an xe engine)

i just went for a normal piper x induction kit with cold air feeds...works a treat with my other mods

I think a well designed/intended induction sounds far better than a conical filter with too much surface area ... once the filter provides surplus needs for the engine I think it sounds horrible!

I could listen to the induction of the new impreza Sti 300bhp monster that glides up the lane all day long though... ahhh

[starletsr]

Well reading all that giving me a headache

My cousin just said "induction kits are good on turbo cars, not on non turbo, the best way is to drills 5-10 holes on the standard air box 10 or 12mm, it will get you the power and the sound"

Seeing that he works for "Impulse Performance" for japanese cars, i think he knows best, but everyone has their own opinions innit guys.

try improving the BMW M3 intake, nigh on impossible

must be about the only thing they got right then. cos its basically just a high powered, not that heavy, very slow car, for almost 50k.

Hmmm, 343 horses, where do they go? 3.2litre 6 cyclinder in a a 1500/1600kg car and yet still is over 5 secs to 60. And handling, well lets not even bother going there.

That all depends on what he does. I worked for the Police for 3 years, don't mean i know best about the law or arresting issues etc.

Anyway, No ecu reset is required, the ECU is far too new and has the ability to real time change, bit like the 03 scoobs. most factory airboxes are restrictive, just cost car manufactures are getting better these days means diddly, else why would you need to change anything, suspension? brakes? etc.

Power gain on the 1.0 and 1.3 aren't gonna be much, but on the 1.5 it ain't bad. s i've said on other posts, my other half went from the standard tsport bhp to 119bhp with HKS induction kit and HKS backbox. Thats pretty damn impressive if you ask me.

During taking her ind kit off as i was fitting cold air feeds, i ddin;t plug the maf sensor back in, and indeed she had the little warning light come on. Easily fixed by the reset thingy you can do with turning ignition on./off etc etc and it has never come back since.

I think you will find, that putting a air filter in and adding extra cold air is a good idea, but will never gain as much power as an inudction kit due to surface area or someting, hence why the hks is a mushroom shape and they all are genreally kinda similar shapes like k&n, blitz etc. Totally agree with not having any oil impregnated filters though, same with the scoobs, but most people just dont listen. I think it take quite a while to clog up the maf sensor though unless the filter is dripping with oil which is shouldn't be.

damn shame there is no motec ecu replacement for the yaris, as these do away with the maf or so i believe.

u got 119bhp from an induction kit and back box? that sounds good...the T-sports r 108bhp standard yea? in which case thats a 11bhp increase! (impressive)

but to be fair, assumin u didnt av the car rr before the induction kit and back box were fitted, u cant really say exactly how much power increase the mods made! (ok u get a good idea! which is good :))

also not all rr are accurate! i av a m8 with an escort cossie, and he has been on 3 different rr and each time his cossie was in the exactly the same condition (nout wrong with it, and it had the same mods) but there was a 10bhp difference between the 3!!!

i agree that a modded air box with performance pannel filter is a good idea, (hence y im doin it) but the reason y i decided not to get an induction kit is coz...

they cost a lot more than £30

they are prone to suckin in hot air

and it will be a fair bit of hassel to make a very good heat shield and make sure the cone gets enough cold air at the same time

and lastly tbh i cant see an induction kit (on a T - Sport) getting much more of a gain than a good/functional/effiecent modified air box.

also im not bothered how much gain my bros car gets, obviously the more the better, but i would only expect about 1-3bhp max from a modded air box! even if an induction kit got 5bhp, i know u wouldnt notice the difference in the performance of 2bhp! (remember its a 2bhp difference at the fly not at the wheels!!!)

as for ECUs, wats the score with the yaris T - Sport? can the dastech (sp!) unichip be used?

my bro is interested in gettin his chipped, but iv told him to get the breathing sorted out 1st! so after he gets a full exhaust system, then maybe a chip will be on the cards :)

the T-sports r 108bhp standard yea

according to toytoa its 106, but some places say 107.

assumin u didnt av the car rr before the induction kit and back box were fitted, u cant really say exactly how much power increase the mods made!

car was brand new, so unless it came out the factory with increased bhp which is unlikely, the increase is easy to tell. Only thing is you cant really tell the performance gains you are gettng, as she test drove a t sport but thats not like owning one before hand.

also not all rr are accurate! i av a m8 with an escort cossie, and he has been on 3 different rr and each time his cossie was in the exactly the same condition (nout wrong with it, and it had the same mods) but there was a 10bhp difference between the 3!!

indeed they are not, but 10bhp on a cossie is a very low %, so that would equate to very little where the yaris is concerned.

as for ECUs, wats the score with the yaris T - Sport? can the dastech (sp!) unichip be used?

here ya got me, there are several posts on here concering chipping. As i said before, recplaing the ecu or remapping it is the way to go, a piggy back chip is not, unless you don't plan on keeping the car or don't care what you are doing to it. Piggy backs generally feed false info to the ecu for power gains, and that is just not worth the hassle. As you said, if you can't get enough cold air to the ind kit then its not going to be much good, but apiggy back can tell the ecu that its getting plenty of cold air when its not, so u get the performance but at what cost???

I think its a amtter of time before these kinda things become available, its stilla fairly new car, and in the last year or 2 the amount of mods has increased well. Bigger injectors, fuel pumps and lots of cooling will hopefully one day be around.

[SRi_James]

agreed 10bhp on a cossie is a very low %, so that would equate to very little where the yaris is concerned....but still, a few bhp is a few bhp :P

i know wat u mean wen u say piggy back ecu are pointless as they can not be mapped....but there are a few exceptions...

i have a superchip on my corsa, and it has helped my engine by increasin the fuelin/timin and more importantly makin the rev limit higher...my engine now revs to 7000rpm (above 7500 and u must change the rod bolts)

with the vauxhall xe engines they need to be reved to get the most out of them, and thus the superchip has helped me, but if i had more funds at the time i would have gone for a dastech (sp!) unichip. ok the superchip is not mapable, but i can get an adjustable fuel regulater (a fse power boost valve) and adjust it with help of a rr session (which i need to do as im over fuelin at the mo!)

both the above r piggy back ecu chips, BUT the unchip is also mapable (to every 50rpm) which is good!

so a unichip would be benifitial to a T-Sport with breathin mods, as it can be mapped!

u obviously didnt realise a unichip is mapable (which is fair enough! i didnt know untill i was told!)

but it would be cool to see someones results from a rr of a T - Sport with induction kit, exhaust system and unchip!

i recon in the region of 120-130bhp would be the result! :)

yes indeed. as long as no false info is fed to the ecu for gains then everything is cool.

the reason i'm against this is cos i have a scoob, and people often chip the scoob in order to up the boost. Now, my car's boost runs at 0.9bar stanrd and if you up to to 1.2 or above it will over boost, basically the ecu cutting of fuel to stop dammage to engine/turbo etc. However, chipping can stop this info being fed to the cu, so you can wack up the boost to someting silly but as far as the ecu is concerned you are poodling alond at say 1bar, and thats when things go bang.

130bhp in a yaris would be pretty fun, not sure what the internal are goo for, good enoughf or this as i beleive the s/c takes it to over 150 from a standard engine.

as you say a r/r is the best way to hange various bits. u seem ot be fairly aware of other things to change etc, i only know odds and sods, but many people just want power and do not realise what to do and what not to do. as you said, over 7.5k revs and you need to change things, some people would likely just wack it up and wonder why it went bang.

i lok forward to my other half one day getting the s/c and whatever else is avialable withint limits anyway, as they are a fantastic little car.

[SRi_James]

the more i think about it, the more a unichip sounds appealing for my bro's T-Sport :D

im sure the standard internals would be absolutely fine for 130bhp! as u say the sc is 150bhp on standard internals!

my bro said to me wen hes bored of his car i can av it/buy it off him, and then carry on moddin it...id love to get his lump sc or turbo'd!

but thing is im not too keen on turbo chargin a NA engine, i dont know about sc tho :S

maybe in the future TBs will be available! :D

anyways i doubt il get his car, as im gonna sell mine in the summer and get a turbo (well thats my plans :))

im lookin forward to fittin my bros lowerin kit and strut brace, and modifiyin his air box...roll on next month! :D

here, wat scoob do u av tiktok? wat mods u done?

here, wat scoob do u av tiktok? wat mods u done?

get yaself on either SSC or Assassin and post a newbie thread on there, and i'll talk about my car.

not really the place to do it in the yaris forum. B)

sorry cba :P

Guys, I'm new to this forum, I'm an Elite member on the Primera Forum (my cars a new model SVE) but I mostly drive my wife's 1.0 GLS (1999) due to the economy. I've been checking out the issues with regards to oil contamination of the MAF, and K&N warn about over oiling, but from what I've read, the MAF's seem a little fragile as it is. My Primera is on a K&N and no issues, and I ran a 1996 Micra on a K&N some years back without problems. Thank goodness your MAF is only £120 ish, the Primera ones run in excess of £300. A new filter shouldn't cause problems, only if you 'service' it with too much oil.

The guys on the primera site all use a variety of induction kits - but were talking 150 - 200 bhp on these cars. What can be worse, a Toyota recommended interval of 4 years, or spending a few bob on putting a much superior filter on. Not sure about the Yaris, but the Primera re-circulates crank case gasses after the filter anyway, so there is bound to be some contamination.

As mentioned, MAFs can be cleaned, but I'm not sure of the process (something like carb cleaner solution), but haven't had this problem yet. I'm looking to fit a K&N panel filter to our Yaris, not an induction kit !
