Hi
a lad in ym area is selling his clio, and returning it to standard before sale..

has these mods for sale..

any of them worth me getting off him?
anyone with experience with them.. tell me the benefits.. etc.. also which ones make the car louder.. as am not keen on that..

first is Ramcharger induction kit..
identical to this.. K-Tec Racing - Renault Tuning & Styling Specialists

this induction kit.. does it add sound, i.e. make car louder? because he has a big fat exhaust so i can t tell if its induction kit or his exhaust.. by the looks of it, wont make sound..

second he has an ecotec valve
same as this.. but different colour.. K-Tec Racing - Renault Tuning & Styling Specialists

not sure what it does, could someone explain?

thirdly he has a boost valve.. same as this..
K-Tec Racing - Renault Tuning & Styling Specialists

any of them worth it? he is selling them for like half the price mentioned on the ktec site..

he has others, but these are all i were intrested in..

p.s. his is 1.4 16v like mine aswell.

Hi,

The boost valve with the induction kit are worth having together;

The boost valve is worth having on it's own, but you'll get another 3-5bhp with the induction kit,

The induction kit on it's own is little use, and yes it does make the car louder but not from the exhaust end, you will hear the air being sucked in through the filter, very distinctive and 'boy racer' sounding - waste of time on it's own imo.

The Eco-valve no idea, never heard of anyone using them, which possibly means it's one of those fairy tales like the fuel line magnets, couldn't say to be honest, they may well be fantastic (but usually when they go on and on with the science it's because there is none, it's just bull) - It either works and they have no idea why, or it's total rubbish - they don't tell you 'why' the oscillations and vortex helps, only that it does, sounds like ¤¤¤¤e to me.

The biggest gain will be from the boost valve and these are definately worth having, although you won't know what it was like before so it'll be hard to gauge performance gains, but they definately boost acceleration and low end power, makes the car feel really light and nippy around town, that kind of thing.

I'd personally take the filter and the boost valve, and ask him to throw the eco-valve in for free (cos I'm a cheeky fecker), but they're not useless mods. :)

Hope this helps.

just found out he never actually fitted the boost valve lol so its new but he said that he's not sure if it fits the 1.4 16v engines.. was suppposed to be for the 1.4 i i.e. 8 valve ones..

anyone know if it'll still be alrite and fit?

or of one which is for the 1.4 16v engine?

thanks

Hey eggy790, your desperate to spend your money :d

The boost valve, is basically a pressure regulator that sits in the fuel line, and "evens" out the fuel pulses ... in years gone-by this was called a "malpassi filter king or malpassi fuel king" worked not too bad on mechanical fuel pumps and carbs, but not so hot on electric pumps and fuel injection, do a search on the internet before you part with your money ... personally I'd keep it:(

The eco-valve ... waste of time .... the design of the Clio head has a slightly sunken inlet valve which causes the fuel mixture to swirl anyway, plus how does this work if its positioned before the injectors on the inlet manifold ... all it will do is swirl air ...... gimmic ... leave it at that.:(

The induction kit- great for making a noise ... keep your money buy a skip hat, put it on backwards and play your stereo too loud ... great noise and save your money.:(

IMHO, being an old fart and old fashioned petrolhead, Id save up and buy a better car, its the only way really.:cool:

Hope it helps:)

The induction kit could improve performance,but only under certain circumstances(if the kit is designed for the car and if a cold air feed is also used),but as said previously,you will get a constant hissing noise and a resonating noise when accelerating.:(

The other two are a complete load of tripe,and best avoided.:)

(IMHO anyway....:rolleyes:)

Hi eggy,

I'd say the induction kit is worth a go, not sure about the other 2 though. I highly rate cone filters compared to standard paper and direct replacement k&n's. My personal opinion, and it is only an opinion mind, is every one who owns a car should scrap the standard air filter and fit an induction kit.
My main reasons for this veiw are if the cone filter is fitted correctly it has the potential to increase MPG by a few miles and you will feel an increase in accelaration as they improve torque. Not sure about bhp gains but you can deffo feel the increase in torque when you sink your foot in to the carpet. I've been using cone filters on my cars for years now and deffo wouldn't go back to standard. Yea you will hear it sucking in air but it's not that loud that you're going to get people turning their heads an covering their ears..lol!! I've got one on my Lag II for mainly for economy reasons but as it's quite a large car I'm greatfull for the increase in torque. the filter I'm using at the mo is a universal type cone I got from ebay for £15. I scrapped the standard equipment on my car and used a series of aliminium piping and silicone conectors to fit the cone. The only way you are going to get any gains from the induction kit is if you position it away from the engine, otherwise it's just going to suck up warm air from the engine bay, wich isn't good as warm air contains less oxygen. I managed to put my filter behind and just below the passenger headlight. reason for this is to catch the cold air coming in from underneath the car and from the front bumber. Just be carefull not to put it too low as it might get wet when you drive through puddles. If you are really interested in doing all this have a look at a site called mx-3.com and do a search for CAI (cold air intake) should make for some interesting reading and give you some good tips.

Hi,

I reckon what your'e probably benefitting more from there is just the cold air, rather than the cone directly. It's true that the right cone in the right place or with the right feed 'may' boost performance, but you're talking 3 or 4 BHP at the most and to be honest I think the gains are more perceptive rather than real; I dunno, you'll get a lot of mixed opinions on these things. ;)

Lol, I guess I should have mentioned that all the great things about boost valves are associated with mechanical pumps, thanks fellas for constantly showing me the error of my ways. :eek:

Hi,

The gains are more real than you would expect from such a simple mod. I'd say about 3 - 4 bhp is about right. The torque gain might be a bit more though, this is the bit you would notice more that has improved rather than the bhp.

It's more about freeing restricted air flow, the standard air filters fitted to cars, are made of paper and does restrict some airflow into the engine. The primary job of the cone filter/K&N replacement panel is to free up this restricted airflow. You can easily experiance the difference between the filters, just simply try to blow through each and you will notice it is easier to blow through the cone or the K&N compared to the paper. The theory is the more air you can get in and quicker, the better the performance. I appreciate the gains arn't massive but coupled to the benefit of getting colder air into the engine, it is noticable.
Especaily where the MPG is concerned. I bought my Lag II in December 06, when I first had it, on the run to work on an urban cycle the computer said it was returning 27mpg. After the air filter mod that went up to 29 - 30 mpg. After a 72000 mile service, plugs oil, cambelt etc it's now giving me 32-34 depending on how heavey my foot is feeling!
As petrol prices continue to rise I'd say they are very benefical just for the associated savings there.

Thanks for all replies..
i think am gonna let them pass.. i'll stick to my k&N panel filter. was just thinking if extending the cold air pipe goin to the airbox from behind the headlight to the bottom grill, for colder denser air would make more difference? is it worth doin? moving it to bottom gril.. ?

if it is.. what sort of size hosing or piping am i looking for.. and how could i go about doing it?

cheers

Hi again eggy,

Moving the air pipe from behind the headlight to the grill in my opinion wouldn't really make any difference. The original equipment (air box in particular) are prone to suffer heat soak and your not really going to get much more cooler air in the new location. It might work slightly as ram air induction as the pipe is in the open in the grill and the quicker you go the more air forced into this pipe, but I doubt it'll be noticable. If you are going to the trouble of spending the money on the extra piping to move this feed, you might aswell scrap the lot and go for a cone and sell your K&N pannel to contribute to the cost.

If you do want to get some piping you want to get the biggest diameter you can fit under your bonnet. Start looking at a 3 inch inide diamter silicone couplings and a 3 inch outside diamter ali piping. The sort of stuff you'd use to make an intercooler kit. 3 inches should be sufficiant for your 1.4. If this is too big go for a slightly smaller one, say 2.5 inches but I wouldn't go any smaller than that as you'll start to restrict airflow.

Cheers
Mike

I think if you buy a K&N cone there is some flexible hose in the box cant remember how long it is but would think its around 2.5-3 inches wide. Its about 4 years ago since i bought one but might be worth checking first before buying the hose.

well i'm getting a bmc carbon dynamic airbox from my cousin now.. he's gettina group buy on them.. discount price..

will that be fine as it is comes with a half a meter long cold air feed? this wont suffer from heat soak will it?

or should i extend it to the bottom grill ? will this make a difference on this one?

also wont it fill up with crap down there? will that affect it?

Cheers

Hi, i had a carbon induction box with a K&N inside. It was orginally £300 but i bought for £200 and was like new. My mouth on the box was around a foot wide by 4 inches deeps then tapered small to were the cone was inside i did not use any pipes for extra air as it fitted nicely in the grill. I used to take out around every 6 months to just clean and check it was ok. Sounds nice in box and slows down the heat soak.

Regards

Dave

Hey eggy,

I just did a google for a bmc carbon dynamic airbox just now. It does look very good.

It's still basicly a replacement cone filter, but with a carbon fibre sheild around it, this will prevent heat soak. It does look like a good filter though, if you are getting it cheap I'd go for it. A new one for an MR2 costs about £180

If you're gonna put the ducting in the grill, put it as high as you can, other wise no driving through deep puddles. As to it filling up with crap, you're more than likely gonna get a bit more in there (flies, leaves etc) than if you put the ducting else where, but that will just mean you have to clean the filter a bit more often. With the ducting in the grill though it will work better as it works as a Ram Air induction kit, the quicker you go the more air is forced into the intake = better performance.

You'll still need to buy some piping for the other side of the carbon box to the throttle body. Unless you can get it from your cousin. You'll have to remove the original air filter box with your K&N pannel in it, and attach some piping from the throttle body straight to the carbon box. Try to keep the number of shap bends down to a minimum though as this restricts air flow, keep a nice smooth path for the air to flow through.

Even though you might spend a bit of cash now on a decent filter and connecting it up properly with ali and silicone piping, the good thing is you can take the piping and filter with you when you sell your car and put it all on your new one! Just remember to keep the original equipment for your car so you can return it to standard when ever you want.

hey thanks for reply
getting it monday.. suppsoed to come with all pipes and hoses neccessary for my car, if it doesnt fit and an elbow is needed (is that what you were describing?) they'll giv me it tuesday...

are you definately sure that for my model car an elbow is needed to attach to throttle body?

as its universal and the guy told me, if you do need an extra part it'll either be an elbow or a flange..

Cheers

p.s. i dont plan on doing the cold air feed to gril, coz me lazy and wont rly clean it often..

just gonna see where the 60cm one provided goes to.. most likely same place as the current one behind headlight..
