ok, having a little discussion on 205 forum and Rapidcossie has mentioned the need for a nice gap from the trumpet to the filter

my TB'S look like this and as you can see a ITG filter will go straight on,


another guy has this setup




and another guy has this setup






anyone know the answer to what the best setup???

 

on my 100E I have the same filters as the bottom pic, I know I'm on carbs but the principles the same..

Not speaking from experience or great general knowledge on the issue, but one of the most governing factors that people have influence their decision over a filter is the space they have. Especially in most Fords where the inlet manifold is glued to the bulkhead, there really is limited room. It's all about how the air flows basically. You don't want turbulent air flow, you want as smooth a flow of air as possible in order to get the maximum amount possible into the trumpets at the fastest velocity. I don't think there is much wrong with EITHER of the two setups you have shown. I reckon if anything, the first setup is better but either would be as good in my opinion.

 

thanks for the replies both, give me something to think about

 

i hope the guy with the first setup is going to make it out of something a little better than carboard!

 

Socks tend to be regarded as shit.

If you've got the room an airbox would be ideal! - Pipercross do a nice one for tight spaces.

 

Just an idea..

Why not combine the two together?

Have an air box like the first one but without the panel filter and have filters on the trumpets as in the second picture.

 

I've got one of these on my bodies and it's fine.. lets buckets of air in with minimal ristriction:

One of my friends runs the same set-up but got kicked off a track day because the car was too loud.

I was considering one of these though to quieting things down a tad:

There is the pricey option too

 

socks are'nt regarded as brilliant, as there is a mis-conception that they get sucked into the inlet under heavy accelleration. although true of earlier types they dont do it anymore if you put them on properly and secure them behind the trumpet with a ty-wrap or something!

either set-up would be fine and as said above is mostly governed by space and cost. the last time i looked, socks are cheaper than the air box, but the airbox used up less space!

hth

 

Mine doesn't have any filters



No space for anything other than socks....

 

I will be running filters ...lol

 

I ran for about 8 months without any filters.

Will be running an airbox on these new bodies though - eventually!

 

A good filter should be so free flowing that its distance doesnt greatly matter.

Loads of the XE boys are running big power with a domed ITG filter only an inch or two away from the trumpets from where its bolted up straight to the backing plate.

I'd just do that if I were you.

 

No filter is just silly IMHO, only takes one small stone to go up there and its new engine time, just not worth the risk, id at least run socks if you cant get anything else in.

 

Hard to get the back plate to fit due to the injectors being in the way.

 

In that situation, use socks is my advice.

 

Binned the socks!

I'm going to try the above with the airbox (which I have) but can weld the base plate to the trumpets futher forward. Providing I have room!

Problem is, without it being mapped I don't want to drive it to the mapping place with socks on, in case of fire.

 

well my TB's as above are al ready for a ITG dome filter, think i might make a tunnel from the grill to the dome to stop heat soak

 

surely you will only get this if they are popping back? in which case a dome filter would just as easily catch

 

if you can't get any for of filter on or at least a sock, at very best run some sort of thick mesh so it will stop anything from being sucked in.

I must admit many moons ago i ran my 2.0 16v nova without any form of filter for over a yr

 

I'm not running any filter on the drive down.

 

its surprising just how much sh*t you suck in on trackdays.

i run my m3 without headlamps with just mesh in front of the air filter.i have had some running problems where the car runs very flat and have ended up removing all the inlet manifold,had the injectors cleaned,new fuel lines,filter,press reg,afm,lamdas.

just built it all up and was about to refit the induction kit so decided to clean it up a little and the cone filter inside was completely blocked with thick shit-as this was the only way air could get into the engine im presuming this was the original problem!
how stupid to overlook one of the basic things!

its been cleaned out overnight and you can now see through it,so im hoping it will al be fine when back together now.

 

fingers crossed for you then matey

 

How much power should you be running now Spiky? (with bodies?)

Bet it's a right old laugh in that car!

 

well, i'm hoping for a figure of 180+ ATW

pub figure of 200-210 ATF

 

Nice, and what's that weigh?

Anywhere near 200atf I'll be a happy chappy with my ZS.

 

well i had it weighed at 860, few things have gone now, so i'm hoping for around 845'ish

pre TB 205bhp/tonne
post TB 250bhp/tonne

 

spiky please stop it with these threads, i have no money as it is! the temptation to strip my 205 and rebuild it along the lines of your car are becoming harder and harder to resist!

 

lol


good "cheap" fun

 

well spoke to my mapper again

and have decided on this one

[url=http://www.merlinmotorsport.co.uk/p163/ITG-FILTER-JC50-65/product_info.html [ ITG JC 50 /65[/url]

this gives 50mm from trumpet to filter

and will put some carbon fibre sheilding above the rad (to copy rapidcossie.lol)
that should reduce heat soak and direct the air from the grill to the filter
