Bravo Belinda the New Bravo T-Jet

No errors at all, litterally all you are doing is removing the recirculation in favour of a cone filter. No errors just a silly tishh noise

So did you basically replace the Bypass valve with the cone filter? Sorry I can't find the original thread but this does look like a rather interesting mod and I'm trying to get my head around how it works.

Not replacing it at all, it works really well as is in my opinion.

All you do is stop it from recirculating back into the turbo, in favour of a cone filter to improve response and of course the sound

Ahhh okay, so it's basically a really cheap alternative to getting a Aftermarket Blow Off Valve, that sounds nice and works just as effective? I'm not quite sure how it would help improve responsiveness unless it's less restrictive than the recirculation pipes and allows for more air to be pressurised between the compressor and intake manifold when shifting gears.

It would be exactly that yes

Like I said, it's probably all in my head, but it seems better..

Well I think it would actually be the case because those cone filters are quite constrictive to an extent. I fancy this mod quite a lot actually. Although I must warn you now that the air isn't getting recirculated the Mass Airflow Sensor aka MAF is getting incorrect readings and cause problems. I've read on a couple sites and will quote the problems associated with it. " In the case where a mass airflow sensor
(MAF) is used and is located upstream from
the blowoff valve, the engine control unit
(ECU) will inject excess fuel because the
atmospherically vented air is not subtracted
from the intake charge measurements. The
engine then briefly operates with a fuel-rich
mixture after each valve actuation.
The rich mixing can lead to hesitation or even
stalling of the engine when the throttle is
closed, a situation that worsens with higher
boost pressures. Occasional events of this
type may be only a nuisance, but frequent
events can eventually foul the spark plugs and
destroy the catalytic converter , as the
inefficiently combusted fuel produces soot
(excess carbon) and unburned fuel in the
exhaust flow can produce soot in the
converter and drive the converter beyond its
normal operating temperature range.
An alternative method for utilizing both a MAF
and a blowoff valve is to have the MAF
located down stream between the intercooler
and the throttle plate. This is known as Blow-
through rather than the traditional Draw-
through set up. Care must be taken as to the
position of the MAF to prevent damage to the
sensitive element."

Yeh but it sounds good

Hahaha yeah I know it sounds good just don't want him to break his beautiful Bravo. There should be away around that problem though, so it can be running smooth and sounding good

Luckily for us then these vehicles don't have a MAF?

They run off a MAP sensor in the intake manifold. I tried looking for the MAF last week and after not finding one, I googled it and sure enough these engines do not have a MAF sensor.

Unless of course, my car is missing mine. In which case I wouldn't be clocking 40+ MPG.

Honestly, I can't see how that mod would have any adverse affect

That is honestly like the best news ever, I'm so totally gonna do this mod :slayer:

 

[aross95]

Hi i like this mod too ,is there kit to buy or did u make some or buy seperate parts ,thanks ?

 

[RobBravo]

I bought the items separately on eBay.

You need:

1 x 25mm breather filter
1 x 25mm solid alloy pole
1 x 25mm hollow alloy pipe

And some jubilee clips

Hope this helps

 

[aross95]

Hi ive found the filter £5.50 but cant find the pipes ,any links ,so i can get the right stuff and some info on how to do it once the stuffs here , im not to good at this stuff , thanks ,apreciate it

[aross95]

Yeah thanks very much ,did u just take off the rubber hose and put the filter at the top hole and block off the bottom ,or is there something else , sorry dont mean to be a pest

 

[RobBravo]

Yeah that's exactly right

 

[aross95]

So u think this would work to block off bottom piece

 

[RobBravo]

Of course it would, that's it's job

Hi after ordering the stuff it came last week ,but didnt fit right so i ordered same but different sizes and its fair to say now its done ,i love it the noise it makes is awsome ,although my wife doesnt like it as i seem to be driving around now with windows down and stereo off so i can listen to it lol but thanks for your help ,much appreciated?

I'm glad you like it mate

Any1 had steering wheel problems with the bravo sports the leather seems to be thin any ideas how to fix ????
