Discussions of HP as measured on a dyno or boost response/RPM as measure in the car during an accel leave out one important factor toward good drivability and time to speed road performance. That unfortunate truth is all turbocharged engines must first perform N.A. before they can deliver boosted performance.

Some increase compression ratio. Why? Obviously to make the motor stronger N.A. so it can better pull itself up to that magic time when the boost needle responds. However, ultimately this motor will make less power on a dyno than one of 7.5:1 C.R.

No one wants be “off boost” but it is a fact to be dealt with. Most component evaluations on turbocharged engines require on road performance comparison and subject driver input of drivability. These considerations can make your Porsche motor respond like the performance engine it is, or frankly a bunged up high torque diesel wantabe.

Throw away the boost indicator and give it a try.
