Zero PSI turbo - Toyota Yaris Forums

Bluevitz-rs · 04-14-2011, 02:37 PM

My ass told me so when my boost gauge read 0 and I was only at 2000 rpm. As soon as I took the turbo off, I didn't have nearly the same pull at 2000 rpm.

The whole point of it is to make a high flat torque curve from low rpms for efficiency.

Edit: Ok, the point I'm trying to make is that an N/A engine is only sucking in as much air as it can due to volumetric efficiencies. As RPMs go up air inside the air inside the intake track speeds up compounding the effect and power is increased. With the turbo, you have a constant rate of air being pushed by the turbo eliminating the need for high RPMs to achieve the desired torque.

Holy crap, sorry for thinking outside the box.
