Qashqai 1.2 turbo (Acenta SV)

Post by Active » Wed Jun 08, 2016 7:15 am

Hey,
I've ordered Acenta SV with 1.2 turbo,
I wanted to ask if I can install on it blow off to the turbo and if it will hurt the engine or the car in anyway?

Thanks.

Hi Gel, I think Active means this device - take a look at the attachments, but whether the QQ has it already installed I have no idea. Being new perhaps it is already installed and Nissan should be contacted or asked, because playing around with or adding something like this could well be a big problem for the Nissan Guarantee - Dave ;)

A bad idea.

Because the ECU monitors the flow of charge air entering / exiting the engine, it will have assumptions of how much air exists when u remove your foot off the accelerator (hot compressed air gets returned to the front of the turbo compressor to reduce the boost pressure but keeping the turbos RPM high). If you discharge the compressed air to atmosphere you will get an engine warning after a while because the car thinks u have an air leak.

I used to have one of the blow off valves on my mini cooper s, sounds great, makes no difference in performance I could feel & after a few miles of hard driving would throw an engine warning light and reduced performance. The car ECU would need engine management coding to stop the fault warning.

If u want to increase performance then the best method is a "ECU REMAP", not one of those crappy black boxes.

Anyways, your driving a crossover / suv not a sports car. A dump to atmosphere valve would make people who hear your car think your a total W****r. :shock:

Hey Dave,

You are not old and only as old as you accept yourself to be.

Bros in Singapore install the racechip ultimate and our 1.2L dig-T become quite a beast !

We only have all petrol variants here, 1.2l dig-T and 2.0L ....how we wish we have the 1.6l dig-T to slap on the racechip ultimate !!!

Cheers.

Richard

just to clarify. As above, all (most) turbos either vent back to the inlet, or vent to atmos. As standard, nearly every turbo'd car out there vents back to the inlet.

you can only fit a vent to atmos BOV IF you car uses MAP to read the air pressure (ie it reads absolute PRESSURE the inlet manifold). If your car uses MAF (reads the air FLOW at the air filter/air pipe) then in general you wont be able to fit a BOV as it will upset the metered readings. I'm not sure what the Qashqai engines use, but I would imagine most modern engines now use MAP and maf is a fairly old and unreliable system now, but still used I assume in some engines.
