Ive had an idea, would this give the yb more low end power??

i was thinking the other day, and thought the yb needs to breath all the way through the intercooler back through the blower right to the airfilter when its driving normally.....

what would happen if you had a t piece boost pipe on the inlet plenum side and ran a airfilter next to the header tank(obvesouly with a heat guard)

here the thing it would need a flap before the air filter which moved so when theres no boost presure its open and soon as positive boost say 2psi blows through it shuts it off...


surely having a filter right next to the inlet would help the engine breath easier and make more power and cause less lag and use less fuel off boost...

what do you think?? the flap could be similar to the mfi unit on the rs turbos made of metal and can move easily either way

Sounds far to complicated, and even if it did work then what makes you think it would give more low down power?

The air won't be cooled, and as you then have no exact control over boost you couldn't guarantee what presure you would run, in fact I think it would cause endless problems as it draws in to much air which isn't monitored.

Also, it would draw air in from the easiest route possible.
And even a turbo'd car on no boost is still spinning at a very fast rate to still expell the exhaust gasses and control the intake air volumes.
Mapping would become more or less impossible for this form of setup.

but surely if the flap was very loose when the car is in vacuum it would keep it open as so soon as it hits 0 vac and then 1psi it would push that flap shut and the higher the boost the harder the flap is pushed and better the seal would be.. to shut that filter off....

all na cars have a filter right next to the throttle flap it must be a far less restrictive way of air flow... the air woundnt need to be cooled down as it only bonus is off boost driving..

mapping wise it would only need to be mapped in the vacuum area and may be 1 or 2 psi
of boost

surely the map sensor would pick up the different pressure...

surely driving off boost would be far more responsive

wouldnt make a difference due to the comp ratio, it would need to be higher...........then your're fucked when on boost.

Only way round is sequential turbos like everyone else has done FD's/2JZ etc
