Is it beneficial to recirculate dumped air back into intake. I have an HKS ssqv for which an attachment is available to allow this. Any advice appreciated

Thanks

Hi,
I'm no expert but my understanding is that the recirculated air assists the turbine spin up quicker hence reducing the 'lag' feel which can be experienced.

If you understand how the turbo works, excess air after the turbo creates back pressure reducing the turbine movement when the accelerator pedal is released. Releasing the air using the recirculation valve and returning it to the exhaust inlet (on the turbo) gives the system a head start spinning up and that in itself reduces the lag effect.

Remember : the air being recirculated is atmospheric not exhaust gasses.

The principle sounds good to me so I'm sticking with it

Hope this helps

There have been loads of threads on here about the pro's and con's...........do a search..........but in the end its a personal thing I think.

Thanks for your reply. My understanding is the same however I am advised that the HKS SSQV is capable of dumping massive amounts of waste air and that this amount of air will not readily fit into the intake thus causing back pressure as refered to by yourself. Also forcing air into a fixed space causes temp increase does it not.

I think i will leave to venting atmos.

Hi,


Interesting point how it can dump even more air than the standard fitment. This must mean the stanard unit it adjusted for smaller amounts I presume.

I guess if you wanted to recirulate the air in this way you would maybe require you engine re-tuned or a different turbo unit.
