Engine seems powerless until higher RPMs

Ahmad88 · 06-20-2006, 06:22 PM

When i floor it the RPMs raises normally but when it reaches higher RPMs you start to feel it pulling and speeding up quicker, could this mean that i have to change my air filter? cause ever since i've had my supra i havnt changed it and im going to change it really soon because i know i have to change.

thats how mine it soo. it isnt until about 3500 rpm that i feel a pull. ive changed my stock filter and recently went to a cone filter and its still the same. i think its just how its suppose to be

o, does yours sound like a muscle car at around 5,000 rpm? mine makes that kinda roar i love that sound.

damdog05 · 06-20-2006, 08:27 PM

That "is" how the power comes on. Turbo cars kick in when the turbo spools up. N/A cars have valve in the intake manifold that changes the flow of the incoming air at about 3000rpm. To give it more torque.

ok what if you change to an aftermarket intake? will it still be the same?
