Thanks Exdos i'll keep all that in mind, i'm just in the middle of purchasing flippers for starters.

No the car is bone stock at the moment, I will be looking for a good coilover or similar setup once i've done the engine tweaks

Hey John, could you share some more info or photos about blocking the front brake duct? I've contemplated doing something like that a while ago, and would appreciate some tips. The initial motivation I found in RP scoop for Z4M, that offers 5rwhp increase via ram effect (more info here). I've also looked for the front air intake by the headlight, which seems quite nicely designed - unless you close the hood, when the duct is totaly blocked by front grill sides...

Oh and one more question about ECU adapting - do you think this holds for S50 as well? Perhaps you have some experience with them? Thnx.

Here's a photo of a brake duct blocker in place.


I've experimented and datalogged with several different configurations and settled on what is in the photo. The small aperture at the bottom is there to allow any water or heavy particles to pass through the duct. I've driven in very wet conditions with this in place and the air-filter box remains dry. The blocker has been on my car for the past 4 years or so. The part is made out of aluminium and it fits into a groove which exists between the plastic ducting and the wheel arch at the top and bottom. It can be removed in seconds if needed.

I've made a part similar to that RP scoop for the Z4M and my datalogger showed that it it actually reduced the power to my MC even in various different configurations, as though it was "bleeding" air out of the OEM ducting.

Although the auxilliary inlet in the Z3MC is behind the front of the bonnet, it still captures air at higher pressure. I know, I've measured it.

I have no experience of the S50 ECU maps but I expect that it will be able to cope with a better airflow.

Interesting re the brake duct blocking as I would imagine it would increase pressure through the airbox considerably......but have you noticed a detrimental effect on brakes ? one of the big issues I had with mine was brake fade and overheating but yellowstuff seem to have sorted that out whilst retaining OEM discs for long fast road runs. It would concern me that brake overheating which is already an issue would be adversley affected ?

The brake ducts just don't work at all really in the OE state, the ducts in the bumper are a brilliant source for forced air though as long as it's ducted to the back of the brake discs directly using some hose.

As c_w says, the "brake ducts" in the front bumper in OEM state are a misnomer, they have no effect on brake cooling.

On my MC, I've made some simple DIY brake ducts where the inlet is bolted onto the front ARB, and I use the brake duct in the bumper solely as an air scoop for the air-intake system, whereas c_w uses the brake duct in the bumper as the inlet for his DIY brake ducting as well as for his air-intake system.

I don't suffer any brake over-heating despite blocking off the OEM "brake ducts" because my DIY brake cooling system actually continuously supplies more air to the brakes than they would otherwise receive in complete OEM state. Same applies for c_w's system. I just prefer to use the bumper as an air scoop for the engine.

mmm interesting re the brake ducting, something I'll look into more next year I think ;-)

Re the MAF housing.....

S50 = seperate to the OEM airbox

S54 = built into OEM airbox

thanks for that dont need Maf housing now

so running an open cone filter do you suffer with massive heat soak? (those running open cones k&n pipercross etc)

also after ive fitted this tomo will i have problems with my idle? had this problem on a focus i had years back.

will post up pics tomo of the beast set up ....if it fits lol
