Hello, I have a question, perhaps somebody can help me. I´m looking of a photo of ClioII RS Ph.1 Siemens ECU (F4R-730), where you can clearly see the badge with its bar-code and all numbers. Would be great, thanks. Best regards Oliver

Do you have any pictures of it? A friend of mine has also a 1.2 16V.

For the first step I optimized my OEM airbox so that it still looks stock-like... (I wrote it in german, and it´s translated by bable fish)...

http://galerie.tomson.com.pl/album10 :) I wouldn´t do it....;)

I think good for Group-F competition with big overlap and high comp. ratio but not for everyday use. I also have something in mind....;) By the way, the DBilas are still longer than these.... http://blog.kornemuz.com/?Sport/2006/01

For that price (DBilas offered me €1350.- inkl. VAT and re-mapping) I can nearly get normal F4R-engine (140hp-version) with under 100.000km, and then I have both, power and torque.... Renaultsport parts are undiscussable.....

In my opinion too short for some low-speed torque left, I think even the trumpets of the Clio 1600 Kit car are longer....

So that´s the DBilas intake manifold. I just got an answer on my e-mail from them with this picture: Hmm.....pretty short and I think it won´t fit in my old Clio engine bay due to bigger hight...

I would keep them as they are...

This are the vacuum hoses for different devices, like fuel pressure regulator, MAP-sensor, brake-assist, charcoal-filter...and one is connected to the idle speed regulator I think.

Why the rsi should have? max power and torque are at lower revs, better aero-dynamics, he don´t need that high revolution level.... JB3-048 (16V) 1. 3.09 2. 1.84 3. 1.32 4. 0.97 5. 0.79 gear 4.21 JB3-078 (RSi) 1. 3.09 2. 1.86 3. 1.32 4. 0.97 5. 0.76 gear 4.07

Thanks for the link, it is still under development, but I will make an inquiry.

If your valver has a steel oilpan it should fit, if it has a aluminium oilpan it wouldn´t fit easy. The RSi gear-box has also longer gear ratios than the valver gear-box.

In my opinion the long single hoses of the K4M´s intake manifold are optimized for goog volumetric efficency at low and medium revs but not for +6000. Also the F4R engine of the ClioRS uses a different intake manifold compared to the "civil" F4R versions. But how to shorten them by keeping the...

Normally they have all the M20 thread. I use the 7700720978 on my 1,6 16V, that has been also used for the R25 V6 Turbo, only double length but the rest fits perfectly an I can put in 0,1l more oil....;)

Hello, has anybody here made a "before / after" dyno-test with the K&N 57i-Kit for the K4M engine, or even a only "after" diagram?? I´m interested where the biggest improvement would be... Thanks Oliver

Mine had 54mm (Oct. 1996, 1.2l w. ABS), but I think from ´97 on they switched to 58mm.

I have Denso IK22 in my car an I don´t experience rough running when cold, they are just great.

You have to differ between charging (generate a pressure in the intale manifold that is higher than the ambient pressure) the engine by the ram-air effect and the decrease of pressure losses by the ram-air effect.

You are right, but you have this effect only in small rpm area, where the single tubes of the manifold are in perfect resonance.

Look in that document: http://home.vrweb.de/~seegi/Pics/staudruck.doc I calculated the theoretical ram air effect. It´s in german, but with the international abbreviations I used I think it´s understandable. As you can see, it´s not much....

From filter area point of view I think Ben is right. I wondered allways why the air-box of the R25 V6 (or better known as "cup air-box") with it´s single inlet with 100mm diameter brought that big increase in ph.1 models compared to the original ones with 2x60mm, I think. (p.s. some edit...

The newer K7M-760 engine in the Megane Mk.2 (113hp) has 40° cam-shaft angle for the phaser (that´s 80° crank-shaft....;) ), but all phases of the RS have 16° as Ben said.

So, I did some silght modifiacations for this year... - painted the wheels black - air scoop now really welded in - ph.2 grill - mud flaps - OEM rear silencer

No I don´t, I work in automotive area but not motor-sports or something like this. Check out this link: http://shop-competition.renault-sport.com/ and then stroll through the catalogue....:D @BenR I´m looking forward to it!

It has, look at the Clio 1600 for Rallye.... Some years ago I wrote a e-mail to renault sport and I got an answer... "Oliver, AS enhenced the Renault K4M engine is, to tune it from 110 HP to 220 HP is a big challenge !! The FIA regulation on the S1600 categorie concerning the...

As far as I know the compression ratio is higher (due to lower charge pressure) and also the 225T does have no vvt.... source: http://www.km77.com/marcas/renault/2004/megane/renaultsport/g02.asp regards Oliver

Yes that´s correct. I like your air intake so much that I will copy it. I found some body that sells a used 57i-Kit, hopefully not too expensive, because I need only the tube and mounts....

I think now you can buy a lot of things for your K4M engine to increase the power, e.g. you can choose between 8 sport camshaft profiles from different brands, oversize pistons are availible (+1mm) so that the bore/stroke ratio is quadratic, you have 1640ccm and increased compression ratio and...

that´s true... :)
