i'v put a pipercross pipe on last night, i put it where the blue circle is, makes alot of difference!! just seems to pick up quicker!!! every toime i change gear now, it seems to pull more than it used to do:D

thanx for ur comments:)

Thats what i'm doing, mine is about 2 inches away from the cone

i used the old airbox feed and a pipe coming from a lower grill.

well the instrucions say put in 4 inches from the cone! - they will know best!

Surely if the intake pipe isn't touching the cone there will be no real suction through the pipe unless you're moving and air is blowing up it? I've got a BFO on my corsa C, and i'm using the intake pipe which was already there, i've got the pipe so it is almost touching the cone, is this right?

mine is in the same place as the red circle and its made a noticable difference.

ttt

Use both..

have one goin to the side, and one from underneath :thumbs:

where should i put the cold air intake pipe???

BLUE OR RED circle????

yes it works when in motion but i was talking bout performance on takeoff. when sitting at the lights the engine bay fills with heat and components get affected by heatsoak. this is the heat that gets sucked in by the pod initially causing the flatspots and this heat doesnt get drawn out the bottom of the car till it is in motion and cooler air is fed thru the front.

Well if you smoke. Try blowing the smoke in front of the car near the air intake and see where it goes. It simulate air movement when the car is moving. So an cold air feed does work, if positioned right :thumbs:

doesnt really work unless the car is moving coz the pod wont 'suck' thu the duct like an air box would... if u know what i mean. u will always have a flat spot when taking off from the lights coz of heat build up in the engine bay. the only really effective way is to isolate the pod from heat via a heat shield or to minimise heat by 'wrapping' the exhaust manifold or bonnet vent.

anyway heres my cold air intake

the one from the airbox is a bit crap isn't it? is it worth putting back on?

im using the bit fomr the airbo, one from the fonrt gril and one form the inner arch
more the merrier i say

I have send this in the past but think it might help there is a high pressure area on the corsa just behind the head light matey get ya filter in there with a cold air feed

Is it really colder lower down, or do you mean it's density is higher because it's lower and therefore gives better power.

No pics but its pretty easy mate!!! Either buy a pipercross one for about £20 or buy some aluminium or similar fair sized tubeing and strtch it from you front bumper(any hole thats big enough, the lower the better, because its colder!!!) then stretch it to just a few inches from your filter!!!

cheers mate, thought that was causing my flat spots!!

ANY1 WIV PICS of there COLD AIR FEED????

If you havnt got one then defo put one on otherwise there will be very little cold air going to the filter and with the engine needing cold air and its sucking hot air its gonna cause flat spots i would of thought!!!!!!!

yeah cold air feed!! just wanted to know if it was worth doing???

worked on my 1.2 8v. Used a 4" dia alumium piping an its made a difference.

Matt

are you on about a cold air feed?

look near bottom of posts for a pic???

i have flat spots at low rev's, just wondered if i put an air in-take pipe going to the BFO, am i likly to get ride of these flat spots:boggle:

cheers:thumbs:
