There was practically no time to despair.
On the first qualifier, the car’s settings were on the mark. The tires were producing more than adequate grip, and the GT-R GT3 was blazing through the Nordschleife at an excellent pace, with other cars looking as if they were standing still. Halfway through the Nürburgring lap where luck plays a huge role in terms of traffic, the GT-R GT3 had been able to come through at a great pace, weaving through the cars just in time, and coming to the long flat out section towards Klostertal I thought to myself, “This is a good lap, it’ll probably wrap up pretty good.” … and that might of made me a bit too bold.
Rushing out of the high speed left hand corner of Klostertal in 5th gear, a car appeared in front of me.
The Dynapack is a type of “Dynamo” that is used to measure engine output, but unlike a roller type where the car is placed on top of the machine, the dynamo for applying load to the car is connected directly to the wheel hub of the drive wheels. Because it is connected directly to the hub, you don’t have to worry about tire slippage as you do using a roller type. You can then change the loads on the car as you like.
This means that you can almost completely recreate driving conditions with the car at a stand still.
We can do things that are like magic; like keeping the engine rpm exactly at 3000 rpm even at full throttle. Its easy on a Dynapack.
This makes it like a machine that was tailor made for recording engine sound.
Since then, we have asked Tanabe san of Amuse for his help in recording engine sound, and the cars with high quality sounds in Gran Turismo are generally those that have been recorded on the Dynapack.
The intake and exhaust sound of a car always sounds best at the engine’s full open, fully loaded condition (under full acceleration) in its power band. (Recently there have been cars that are tuned to sound the best under load conditions encountered in daily use, before the full open/fully loaded state. A good example of this are cars like the Lexus LFA and the Ferrari 458). All “drivers” know, that engines sound the best when the car is at full throttle under load of acceleration, in its power band, when the airflow through the engine is the greatest; when the engine is “flat out”.

On GT PLANET, a Gran Turismo news fansite and one of it’s biggest forums, there’s a consolidated wishlist of things wanted in Gran Turismo (http://www.gtplanet.net/forum/board/kazunori-yamauchi-qa/) and all the items listed are things I totally agree with. And the top item on the list by far, is the “improvement of sound”. (ReadMore)
