I Know this is an old thread, but it's about the only thread on this I could find.
Sentra's time sounds about right. I fired up Gran Turismo 6. I used the 93 Silvia Q's to simulate my 96 S14 base model. The Q's has a NA SR20DE. I added the sports exhaust and the intake kit (which I have) and bumped the power limiter setting down to 152. Supposedly The KA makes around 156 stock. I set it it at 152 to simulate the 124,000 mi I have on my motor. I figured I have lost about 10% HP over the years and the upgrades probably only amount to 5-10HP at most. A KA makes more torque than an SR20, but a hair less peak HP. The power limiter caps the peak HP but not the torque, so cranking it down to 152, it should give a pretty good approximation of a fresh stock KA, or an older one with mild upgrades. I then added about 30kg towards the rear of the car to simulate half a tank of fuel and the spare/jack. I am assuming they account for a 180lb driver in their simulation physics.
For the run itself, I used the cockpit view (it's just a blacked out windshield shaped frame on this car since it's not a "premium" model). All assists were turned off. Transmission was set on manual. I used a Logitech Driving force GT on simulation setting with FF set at max. ABS was set at 0, since I have a base model (no ABS). I also limited shifts to 6500, since that is the KA redline.
The most difficult thing to simulate is the "fear factor". You tend not to have that sense of impending death when sitting in your living room without the violent g forces tossing your body about. I altered my driving style to be deliberately more cautious, as if I were driving in a real car and did not want to prang up my car and/or live out the remainder of my life in a nursing home with tubes stuck in every orifice. That said, I probably still pushed it harder than I would have in real life.
I turned in a time of 10:17. very close to Sentra's time. Sentra said he was stationed in Germany, so I am assuming Sentra is in the military and not a professional racing driver. A professional would likely be capable of 10 to 15 sec faster.
Based on this very non-scientific experiment, I would conclude that "normal" people with advanced driving skills, or amateur racers. would turn in a time around Sentra;s 10:27. A fearless professional would likely be able to turn in a time close to my simulated time of 10:17, possible a bit better.
