Who here owns a Renaultsport?

Fair shout. Sticking a cone filter on the end of some bright blue pipe right next to your hot engine always strikes me as being very chavvy and pointless. However, if you are going to try to shield it and feed it fresh cold air then it could work out well. Plus, bet it sounds awesome!

I thought heat soak wasn't much of a problem with the F4R engine? the air filter is right behind the front grille anyway so cold air would go straight to it. The standard air box is supposed to be very well designed too as far as performance is concerned!

I believe cotten gauze are also the loudest type

Heres the new fog light surround on the car, don't know whether to get a black or silver ram inlet?

I would assume from the front a silver would look pretty much like you have got normal fog lights in, whereas a black would look like you had blanked the flog lights?

I vote black.

Just ordered a 102mm x 1000mm air feed, which is basically the diameter of the inside of the fog light surround.

Filter i got is one of these bad boys

Got to say I think the size is somewhat of an overkill??

Yeah that one is a bit excessive, i doubt the AFM would even register any increase, thats just the only decent photo i found quick of the actual filter on a car

Yeah, but it will look sick when he pops da hood in Maccy D's carpark.

ScoobyDoo69 · 26 Apr 2011 at 17:20

FWIW this is the size of mine...

I've been looking into ram scoops aswell, a cold air feed AND a ram scoop infront of the grill should provide quite a bit of air flow..

Still doesn't justify the size of the cone (IMO of course)! Bigger doesn't mean better!

I generally agree, but green make damn good filters, infact these are used at motorsport levels. As long as you get a decent supply of cold air to the filter, it will perform better, as this has 25% more surface area than the stock paper filter, and cotton is the best material to use for air filters. I'll probably make some sort of heat shield as well. I've even been contemplating getting a pipe made up that puts the filter at the bottom of the car

Is the standard airbox not proven to be better though?

I know, i already agreed above, thats not my car above

I've also been reading that the best place for a cold air feed is just under the top of the bonnet (below the front window). Something to do with the way the air comes off the end of the bonnet. I believe quite a few rally cars use this, any body know if this is true?

ScoobyDoo69 · 26 Apr 2011 at 17:34

Is that not the size you're getting then? If not what size are you getting? Mine is 170mm high with a 160mm diameter - which is pretty big!

I'm getting what ever size green thought was suitable for the clio

daveski · 26 Apr 2011 at 17:39

I would stick with the standard tbh, they aren't restrictive.

Can you move the battery so you can mount the filter in a better place? Long term I am planning on moving the battery to the boot of the car so I can move the airbox.

Infact heres the clio s1600 with ITB's and the "window CAF"

Yeah its a possibility, and thats what many people do with the V6 box, all things im considering. Won't know what im going to do until it all turns up though.

daveski · 26 Apr 2011 at 17:51

That CAF is a scuttle CAF and is meant to be very good.

I want ITBs

Yep there's a sticky over on CS in the Engine sub forum I believe. Panel filter & remap and be done with it

IIRC they had put no effort into supplying the filter with cold air, simply ripping out the standard box and plonking a aftermarket filter in its place. They also didn't test cotton gauze filters, only metal (heatsoak central) and closed induction.
