Am I right in thinking that you fit a type of induction kit to a modified car to help it breath better or is a standard air box ok?

If standard is ok why do so many people have induction kits?

And if induction kits are needed for modified cars how are some people using standard air boxes for 500bhp cossies?

Cheers

Its a noise thing in most cases

 

the bit I don’t get is that I know someone that’s built a very good high BHP track car and that has a specially made induction cone fitted for the extra power

So why spend the money on this if a standard airbox is ok for high power Why would some tuners say fit an induction kit to help your car breath when modified

Hope it’s not just for sound

I tend to stick with the standard airbox with a panel filter. Ford didn't spend all the cash developing an airbox thats rubbish

 

Its application dependant, and all down to the design of the airbox in question, also on N/A cars the slightest restriction can be a bigger issue.

 

Most people do it because the believe in the "+15 bhp" claims, and because they don't know any better.

 

 

hi ste, the evo,s up and running mate thanks for your hard work im just trying to sort the high idle , when its warm its idling at 1.5 iv took th ebattery off like the MLR told me as this resets the ecu then you hold it at 2000rpm for 10, 15, mins but still the same,

andy

 

Nice one mate hope you sort out that idle

 

What could the bigger issue be? Im just trying to understand this

so with all my mods what your trying to tell me is that I dont have a 500bhp N/A mk6 escort

 

The Cosworth airbox was designed to suit power increases for homologation purposes, so is very good up to a it's air flow limit. Beyond this (around 500bhp) it becomes restrictive.

Modern cars have different constraints (emmission compliancy / noise compliancy / safety compliancy (dictating the amount of room available) / cost compliancy (using generic items from the parts bin to keep costs down), so these systems can be compromised and very restrictive from the factory (the Focus RS / ST are a prime examples).

 

Cheers Mike

 

ste just brought it on boost for the first time, looks like the actuater was preset for 0.5 bar so that will do for now , only thing is that sealent you put on is leakin so dont no weather its just not tight enuff or weather its the seal,

andy

 

Must be the seal mate, as I wouldnt want to tighten it up anymore than I did

 

ok mate cu 2moz im at work tonight

andy

 

 

If you fit a mirror image breather tank to a Cosworth you have no other option than to fit a cone filter

 

so is this another reason why alot change them

 

So at what point do you fit an induction kit on a car?

for example:
A cossie and a N/A 1.8 zetec

Cheers

Steve

 

The trick to any form of tuning is to sort out the area of most restriction first. So only when your standard filter and box are prooved to be the biggest restriction should you look at changing them.

The biggest form of restriction on most cars is the standard ECU, lose that and add an Emerald (etc) and you can free up a a fair bit of power these days.

 

why not,....

ford spent a lot of money developing the xr2,...and thats rubbish.....


sorry,...couldnt resist

 

Cheers
