Clio Williams gr.A intake or ITB?

  Clio Hybrid
Helo everybody,
I do have some small problem. Taking a chance that my car being tuned up right now (again) I am thinking about gr. A intake. I have found some pictures and materials regarding such intake - but I do have small problem.
Look at the pictures below

accordign to gr. A renault sport book it seems that the intake should be installed to the engine as shown about

so why on some other pictures and projects this intake is installed and conected as shown under?
It seems that the intake goes in front of ITB

Please give me some information what is the correct way to do it. I though that having ITB we do not such intake?

You can still add an airbox to ITB's, usually made of carbon fibre and its purpous is to ensure cold air is fed into the intakes because they sit so close to the engine.
What your seeing there is a carbon box around the ITB's connected to the airbox

hmm that is a great anwer mate, I though that this is only simply to asure that ITB will not take some dirt from air ;)

Do you know when I could get such intake

and what do you think about ?

can this be installed to clio 2.0 16V F7r?

tight fit, you'll probably need a shorter radiator and everything remapped. Throttle bodies are a very tight fit on a williams/valver. you should check what other people have fitted then you'll have an idea

the problem is that either I don't know how to look or I cannot find dedicated ITB for clio on their page

Or all this ITB's are for all cars

The inlet manifold is the only 'dedicated' part. This exists because it is shown in the pictures I posted. The throttle bodies are generic as are the air horns.

does it make huge difference what size of ITB it is

for example:

42 mm or 48 mm or 55 mm ?

p.s. when I do look at the above pictures it seems that these ITB is way to big to be able to close the hood. Was there any modification made in order to close it?

Do you have pictures of this car?

A smaller diameter and longer inlet length gives better mid range (higher torque).

Bigger diameter and shorter inlet length gives better top end (higher bhp).

It is very important to get the correct diameter and inlet length. You need to talk to someone who can discuss this with you in detail. Any professional engine builder will be able to do this.

the diameters you're quoting do matter, ive got no idea which one you should have. phone them up and ask!!!!!!

i know sombody who put their throttle bodied 172 cup on a rolling road and tried different length trumpets. the longer ones increased the torque quite a bit, again ask sombody who will really know, the suplpiers!

Chadil make the inlet manifold for the F7 large port engines.

They are different to the megane engine btw.

thats exactly what I cannot find out - it is just megane and it looks like New megane.

Everywhere I look all the people have custome made manifold - hmmm

just spoke to simon, the megane manifold they do is for the megane F7R head

the williams head has much larger inlet ports (which he says is bad)

he says to use a megane F7R head

Ok, that is a very important but not good info. Because I have to look for megane head now :(


well it is strange that williams head is not better then the one from megane. I would simply listen to the specialist and look for one.

Can he give you prices for all parts I need in order to install such kit (it can be send on my private account). The problem is that my car right now has enging out and I would like to get everything ASAP.

you'll have to use a stand alone ecu, the original ecu can't do it and neither can a piggyback (SMT6)

i don't know what you boys use in poland, but i would say getting an OMEX mapped in poland won't be easy!

As said, use the Megane F7R head as the ports are smaller and also a better shape, the Williams ones are totally wrong shape for ITB's, although you can use a paired body solution like Webber Alpha... but they suck imo.

For your map speak to Andy at GDI as they are partnered with Omex.

Ok it is clear that I would search for Megane head (f7r) - that should be not a big problem (it cost in Poland aproximately 100 euro).

The problem i can see it would be to set the ECU - we use many different stand alones but I have not heard about OMEX in any car in poland.

On the other hand it is not feasible for me to take the car to UK for seting up the ECU.

do you know what would be the total cost of:

- throttle body
- fuel rail
- air filter or air box (i think air box is better because then I don't need to cut out any holes
- all pipes
- Omex ECU

what will be the delivery lead time?

The ECU can be mapped first and sent to you though mate, it would be about 95%+ of the way there as while it's an advantage to have the car there it isn't necessary

how they can remap the ECU if they will not have idea what kind of set up in engine I have (pistons,camshafts, pulleys etc)
 
T

TheJesus

same way when you buy a superchip it's mapped for the car and specific mods. They have done high comp builds on ITB's as well as ITB's on stock engines in pretty much every state of tune. Depending on what mods you run I'm almost certain they can be mapped pretty accurately

Its more specific on a standalone set up due to lack of MAP correction for e.g. It will be quite abit out if he has different cams than the engine mapped for.

Chadil in belgium do a manifold for the williams head...I said that previously. It costs about £240. I can supply one if your having difficulty...

The williams head is fine to use.

If you can get a megane head for 100euros, I wouldnt be complaining, you'd be paying 50-100£ here, plus shipping to you.

the only issue is that i am willing to get all parts from jenvey. They do have a manifold for megane head (wihch i can buy here) which they said is better then the one from williams.

p.s. acutally i just have found whole f7r engine for 150 euro :D

that's not really a problem if they are Cat's, I think Andy has pretty much the whole usable range in stock lol.

aye what i mean is unless a map file was created for every combination of cams/inlet/Cr etc, they wont be great...and i doubt Andy has mapped many various f7r's with many various combinations of spec, so unless he has one for the same spec as this lad is building, it wont be great.

This is what i find everytime I have even smallish changes in cam spec...you upload a map which by all accounts should be close, but when u actually get the wide-band on there it'll be out by quite a bit in many places...usually mid-range where most "activity" takes place.

I would only go with the megane head if its modified.....

we are building the library of files for each spec...

apart from the fueling the ignition changes substantially for different cams

the manifold for the williams is the same for the megane head and the 172, they just need porting to match the different heads
