Very nice bibo!

I love your boost gauge, it has the same color and style with the instuments panel.

Have you noticed any difference in performance after you installed the Alta map sensor spacer?

Thanks, yes the color match is amazing it looks original.

I am not sure about difference in performance after boost port installation, maybe a little bit but I am not sure.

But why would it make a difference ? unless if it's leaking ? Do you have any experience with that matter ?

The only thing that worried me was the fact the MAP sensor gets elevated from its original position.

Most MAP sensors have a temperature sensing element that protrudes inside the intake manifold or piping where they are located. It is supposed to measure temperature directly from the airflow.

By elevating the element, you get the temperature sensing element out of the air flow. So I was worried there might be weird things happening, because the engine management is very sensitive to things like that.

Since everything is fine performance wise, the spacer should be working ok.

Until today we have had a couple of cases where a digital DEFI boost gauge was installed using the wires from stock map sensor.

But there were severe problems (too much knocking and boost problems) because the DEFI gauge altered the voltage level of the sensor to the ECU.

Plus, the DEFI gauge never worked properly without its own map sensor (as I had pointed to my friends earlier) because the 207 map sensors have a different range and transfer function than the DEFI map sensor.

yes everything is working fine.

before I got the ALTA adaptor I used to connect to the car sensor and it used to give weird reading 20 PSI ( 1.38 bar )

What concerns me is that the ALTA adaptor is made of aluminum which will get so hot from the engine and might make the sensor send false manifold air temp.

[salex]

No worries.

Chances are you will have very high intake air temperature anyways, specially when you get your RC tuned.
One tuned RC with stock intercooler reached 98degrees Celsius on the dyno today (at 6000rpm, before finishing the dyno run).

Ambient temperature was 13 degrees C. Cold day. When we went on a test drive, it would easily reach 54 degrees C on 4th gear. That is dramatic.

[bibo207RC]

hmmm, it seams IC is a must especially in my country the temp is 40 degrees in the summer.

salex, under full acceleration I hear a whistle from the engine, is this the normal turbo sound or can this be the sound of my stock dump valve leaking boost ?

Thanks

[salex]

That is normal! These turbos make a whistling sound, which you can really hear when you have an upgraded air intake like yours.

So basically an IC prevent the engine from losing power due to higher intake temp. and maintaning it's power rather than increasing the original rated power ?

To increase the engine's power, you need to get higher boost.
But all turbos raise intake air temperature when boost rises.
The higher target horsepower, the larger intercooler you need.

For 175hp the stock ic is more than enough. But for anything over 200hp the stock ic is very small and the power drop will be noticeable in warm weather (>18C).

That is the reason why you get very high intake air temperature, which stops the engine from being efficient. The turbo raises boost, but the stock ic is too small to lower the air temperature effectively.

Very nice


if I had a RC, I would also !

Thanks, new night picture added in my original post.

Great !
Any pics of the gauge at day ?
(sorry for my english...i was at school....a long time ago lol)

it is very nice....
good integration in the board !

I agree with salex.
You have to listen him carefully.
Is a person that knows very much this sector and of course because of his job see many cars (especially 207's)and many situations

did bibo do something to the BOV?
that relief sound pssst is quite loud..

or any suggestion to make it louder without using hks products and external manifolds or welding?

[Sotiris Bouzikos]

just add an intake kit with free air filter and you will be fine

[salex]

I think bibo is using an intake kit. That is why you hear the bov.

or any suggestion to make it louder without using hks products and external manifolds or welding?

Yes. Use an intake kit. No manifolds, no welding, no hks products for our cars. Just what they already have.

Even a high flow air filter in your stock filter box will let you hear the engine more!

[RC_power]

yes you are right i already have an inbox KN filter.
that whistling sound is ok in every rpm.
but when i pull back my foot after pushing in the low rpm that bov sound is week to me.
i hear that some turbo cars making loud noises after releasing accelerate.
i know they are blow offs sold in every where and it is not worth to mount my rc..
i ll try the open filter like apollo and listen the relief sound
