Brera Cold Air Intake

Latest Mod:
I noticed some time ago that the Brera engine air intake rises from the air filter box in the wing, and across in front of numerous coils and radiators, this made me wonder how much hot air is sucked into the air intake reducing power?
I measured air in the intake mouth as high as 40C at low speeds and this did drops with speed, but I decided this could be much improved.

I will add a word of caution here, the following mod is really for Breras that never venture into flooded roads, infact I don't even take mine out in the rain!

I had to remove the bumper to get at the bolts for the removal of the old intake snorkel:

then I spent some time measuring the dummy brake vent next to the fog lights, and made up a perfectly fitting duct from fiberglass:

this now feeds cold air straight from the front of the car into the std air box which I have a K&N cone filter in.

The result is a 25% increase in air volume and a shorter run to cold air. http://i24.photobucket.com/albums/c2...9_03160031.jpg
Its hard to make out the duct behind the grill in the pic, but trust me its there, and you can here the induction raw listening near the grill.

Re: Brera Cold Air Intake

Awesome mate, nice job! How did you get those figures? Have you had it on a dyno before and after too?

Have to say that during the snow last month that intake would have got a lot of liquid in on my road! But most of the year I guess it wouldn't be a problem.

Re: Brera Cold Air Intake

Wow again JB - you're spending some serious time on that Brera!

Any idea what difference this latest mod will have Sharper throttle, less lag

I always notice a drop in performance in hot summer weather compared to a nice crisp cold winter's morning. Air temp is important.

Just out of interest, what car do you drive when it rains

Hi, thanks m8, temp was taken with a probe dangled over the intake mouth, no rolling road yet, volume of the new intake vrs the old intake is aprox 25% greater in volume/bore, and 2ft shorter.
Yeah as you say, 99% time the rain/puddles won't be a problem, you could say that we should avoid deep water anyway because it can crack our cats/dpf inners

lol, thanks m8, busy! busy!
Yep throttle,spoolling, should all be better, as you say the colder mornings show this up well.
When its raining I drive a diesel C2 with hydrogen kit to stretch the economy, its effectionalty called the hindenburg!

Re: Brera Cold Air Intake

Whats the water4gas all about? Read a few reviews on it a while ago and thought it sounded a bit like snake oil.. Did you buy the books?

Re: Brera Cold Air Intake

Hi Pud, yes I spent many weeks reading up on this, and yes there are many inflated clames for massive economy and this just is not possible, but small gains are.
The basics are no engine burns 100% of its fuel in the combustion cycle, the hydrogen burns some of this unburnt fuel to deliver a small amount of extra energy per "bang".
The result is less throttle is needed and this gives the small gain in mpg.

Re: Brera Cold Air Intake

Might have to 'aquire' the books through my 'sources' and have a read.

I'm pretty sceptical though, it sounds like a scam, like a fuel magnet or something..
