urosr je napisal/-a:Načeloma se poraba naj nebi povečala, lahko pa se tudi to zgodi, sploh pri vozilih z LMM, sam messer zazna zrak, blov off ga pa spusti v ozračje in ne nazaj u sistem, za LMM, je pa tud res da vsak bol prtiska gas ker lepš pihne, priporočam pa blow off znamke bonalume dobiš ga pri rsr, izredno lep zvok ter kvalitetna izdelava, sm ze tri zmontiru in vsak je deloval super. aja pa še nekaj orginal Blovoff spusti zrak pred turbino ne pa u izpušni sistem.

Blow off in LMM pa res nimata nič skupnega, LMM je v ohišju zračnega filtra in odčitava količino zraka ki prihaja skozi filter, blow off pa samo odvaja stisnjen zrak ki še ostane v turbini ko spustiš plin, s tem se razbremenijo lopatice in os v turbini.

Poraba se lahko poveča samo s psihološkega vidika, ker ti je zvok ki piha pač všeč in zaradi tega še bolj pritiskaš na plin.

Ti ko misliš da gre zrak iz orginal BP ventila v izpuh pa me prosim ne uči, hvala...

lp

Ja kam pa gre?? Zgleda da ti res niso jasne niti elementarne stvari? Original diverter valve ima 3 nastavke za cevi, blow off pa samo 2.

Nono, diverterji pa še res nikol niso spušal zraka v izpuh

hribko je napisal/-a:dajte no,zmente se kako je prav in kako ni!
bolj ko berem temo o tem,manj vem
prosim za konkretne in uporabne odgovore PROSIM

1.a se da narest blow off na corso 1.7 cdti'
2.kje se da to kupit in kakšne so cene?
3.postopek montaže

HVALA ZA ODGOVORE

mgost je napisal/-a:Kakšna pa je razlika med Forge in Bonalume ventilom za isto mašino - Peugeot 1.6 Bencin turbo:

V ceni je kar precejšna razlika: Forge > 70€+, Bonalume > 260€+

Q: What is a diverter valve and what does it do?

A: A diverter valve, also referred to as a "pop off valve", "blow off valve", "boost re-circulation valve", "air/boost bypass valve" is designed to re-circulate the boost pressure that gets built up in the intake manifold in between shifts. The valve at idle (under vacuum) will remain open allowing the air to circulate freely through the intake to the turbo (s) fresh air side. As soon as the the throttle is cracked, ie: the accelerator pedal is moved, the valve will be forced shut stopping the re-circulation of intake air to the turbos and allowing all the boost pressure to enter the motor.

Q: Why should the OEM valve be replaced?

A: The OEM valve is what is commonly known as a diaphragm valve. This valve has been around since the mid 80's and has always been a very problematic part that typically wears out within the first 6 months of operation. An improperly working diverter valve will cause multiple problems. First of all, a improperly working or defective valve will cause boost loss. We have seen a 7-9 HP gain on the dyno on a small displacement motor just by replacing a worn out OEM valve with our Billet valve. Second, in between shifts when the valve is suppose to open to re-circulate the built up boost pressure, if it is defective and cannot open, the built up manifold pressure will "stall" the compressor of the turbocharger causing it to rapidly slow down which can cause turbocharger failure. This "stalling" of the turbocharger will also increase turbo lag in between shifts and reduce power. In addition, the EVO DV will flow 10% more CFM of airflow over the OEM valve.

Q: What makes the EVO valves Better than the Original?

A: The EVO valve is precision CNC machined from billet aluminum. It utilizes a solid billet piston and twin Viton O-rings. All internal components are lubricated with the highest quality RED LINE high temperature synthetic grease for a lifetime of trouble free use. Our custom wound piston spring is designed to react quicker than the OEM unit for quicker boost response and more power. The EVO valve comes with a LIFETIME Warranty.
A: The OEM valve is made of a thin wall injection plastic. The heat of the engine will warp and distort the plastic which causes failure. The internal rubber diaphragm is very susceptible to failure from the heat and constant open and close movement. Rubber will dry out and crack which causes the valve to loose the ability to hold vacuum, thus failing. The weak OEM spring is very slow to react which causes a delay in closing, thus leaking valuable boost pressure and slower boost response.

A wastegate is a valve that diverts exhaust gases away from the turbine wheel in a turbocharged engine system. Diversion of exhaust gases causes the turbine to lose speed, which in turn reduces the rotating speed of the compressor. The primary function of the wastegate is to stabilize boost pressure in turbocharger systems, to protect the engine and the turbocharger. The wastegate is controlled by a wastegate actuator in which the actuator is controlled by pressure coming from the intake manifold.

dual port wastegate configuration allows for a second air signal on the opposite side of the diaphragm. The spring or control side. By adjusting this air pressure with a regulator (VBC) either up or down on this side is like changing the spring pressure. You want more boost? Your raise the pressure on the spring side and the wastegate closes. You want less boost? You lower the pressure on the spring side and the wastegate opens.

aja kaksno elektroniko pa dobis zraven pri enem enostavnem vakumskem ventilu? ledice ksne edin mogoce

razlika v ceni je zato ker so eni narejeni zelo kvalitetno iz aluminija in imajo not batek s tesnili, ki dela praktično večno, in drugi ceneni, ki so iz plastike in imajo notri opno namest batka so zato po nekaj časa zelo nagnjeni k puščanju in razpokanem ohišju/notranji opni.

nima pa nobene veze z elektroniko to.

A blow-off valve is designed to prevent compressor surge on turbo-charged engines. Compressor Surge occurs when the engine's THROTTLE PLATE is suddenly closed, giving the Charge from the Turbo compressor, no where to go. So the blow-off is plumbed in somewhere between the Compressor's outlet and the Engine's Throttle body, allow unwanted Boost Pressure to be vented to Atmosphere or Intake stream before Compressor inlet. So, that being said, it should be obvious why most modern Turbo-charged, direct-injected Diesel Engines would have no need for a "blow off valve". A diesel engine is controlled by fuel, thus not requiring it to have a "intake air throttle plate". In a diesel engine, all mixing of FUEL/AIR occurs in the Combustion Chamber, by design the Diesel operates in EXCESS AIR situations, it can pump up to 600X times more air than it needs @ low idle. A Diesel builds peak power and Manifold Boost when UNDER-LOAD, so when you cut fuel to that engine while under load, the Manifold boost still has a place to go since the engine is still pumping air. The manifold boost tends to drop off quickly since it is being displaced by the cylinders, and since the turbine drive pressure will be less as well. This is why diesels do not provide "engine braking" without the use of devices, (i.e. Jake Brake, Exhaust Brake.), where as a gas engine provides said "engine braking" ability.
