The turbo charger is powered from the cars exhaust gases this is why you get turbo lag the super charger is powerd directly from the cars crank shaft therefor it builds up speed instantly so there is no lag the power is there right away
That depends on what you are wanting. A turbo is more efficient but has a delay (lag) on accel. A supercharger does not have any delay, but is not as efficient.
The horsepower is engine specific, without the engine code VTEC is all of the turbo lag without the turbo =)
because it's only a 1.3 and because it's a turbo. look up turbo lag.
The twin turbo engine, has two turbos. With only one turbo, there's what they call "turbo lag", which occurs when the car shifts. a turbo works to certain rpms, but when you shift, all the pressure is lost. So the car needs to starts again taking all the pressure. the twin turbo has 1 turbo that works at low rpm and the other one works for high rpm. With this, you eliminate the turbo lag,...for some they call this new system, "misfiring system" like for the Lan Evo 3. They also call it "anti-lag". P.S. :I just stated the previous answer much clearly.
Hi,I guess this is the Turbo forester.The reason is because the turbo has to spin first before the engine burns the fuel you have sent by pressing the pedal, that is turbo lag.
Its called turbo lag it will happen with any stock turbo and not so much but a little bit on aftermarket.
When you press on the accellerator, combustion gas creates more exhaust pressure. The rise in exhaust pressure increases the speed of the turbo, thereby increasing the intake pressure, which is the turbo boost. You will not be able to benefit from turbo boost until the turbo spins up. That's where the lag comes from. It's inherent in turbo systems. Ive only had one turbo car but I know it had an air pressure activated dump gate that would only allow turbo air pressure to enter the intake at a preset PSI. There were ways to increase ( bigger boost) or decrease (more power throughout driving range) the gate release point with rheastats or performance chips.
Low revs between the range of 2500 to 3500rpm cause the lag you notice before the turbo has kicked in because you need around 3500+ rpm for enough air to be dispelled by the exhaust in order for the turbo to operate optimally. it is more noticeable on older cars due to the inefficiency of carburretters and older type fuel injectors thus compunding the effect of a turbo, who'se job it is to force air into the very same (inefficient) carb that is slowing it down in the first place..
It would have been faster, but the designer didn't want the turbo lag, he wanted the throttle response of a normally aspirated engine.
Biturbo is the same as "Sequential Twin Turbo" Basically, you have 1 smaller turbo for lower RPM range, and a larger turbo for higher range. It helps greatly reduce turbo lag due to the smaller turbo can produce boost much earlier than a super single or twin turbo setup can do. At lower RPM, the smaller turbo spools and produces boost - then when you reach a preset RPM or boost level, a staging valve opens and directs air to turbo 2 (large one) and it now produces the boost for the engine. Usually, stage one turbo is turned off, or its boost is sent into the compressor intake of the stage 2 turbo to achieve a higher output pressure. Do not confuse Biturbo / Sequential Twin Turbo with "Twin Turbo". Twin turbo is having two EQUAL size turbo's. Each runs off its own cylinder bank in V or H type (boxer) engines, or off of a turbo manifold on inline type engines. Both turbos share the load equally in producing boost air. (Like a dual core processor in your PC - both run at same speed, sharing the load equally) So, turbo lag still effects this type of setup, as both turbos will spool at the same time.
if it is only in 4 and 5 gear never heard of that i have a 02 myself, the thing might be is that as you accelerate faster in the lower gears you do not notice the lag that you do in 3 and 5, there are several possibilitys, do you have an aftermarket blowoff valve, they put more wear on the turbo if it is stock, or coould be the turbo going out in itself, the bearings, or the fact it is old how manyh miles on the turbo are there, there are several factors the key thing to look for is check to make sure that there is no problem with the other gears, hell could be transmission oriented, maybe the clutch is slipping but you are thinking it is turbo lag...just saying look into all the possiblities, might not be the actual turbo
