I finally got around to doing some 0-60 runs in the SX AWD while recording through track recorder on my Torque app. Here is my thoughts:
Brake boosting from a start does NOT help, it actually hinders straight line performance. Letting off the brake and mashing the gas without brake boosting results in a progressive build to about 17psi in first gear (will not likely be the case for FWD). Brake boosting results in a much slower build of boost, often hitting around 10psi at the top of first gear. If brake boosting allowed our cars to build boost normally, we'd likely get a better 0-60 time.
0-60 times of magazines are all over the place, and I can't seem to get mine to do better than 7.4 seconds. Maybe my best run was still slightly uphill, but I have not yet beat a 7.4s 0-60, which I find disappointing as I could almost hit that time with my old 164hp Ford Probe GT. Magazines are testing anywhere from 6.1 seconds to 8.3 (which I think was for the FWD), I'm not sure why there is such a large discrepancy. I want a 6.1 second time. I don't see how I am doing it wrong, as all you need to do is mash the throttle pedal. I have driven plenty of manual transmission FWD "performance" cars in the past, so I do know how to launch a vehicle.
Our gearing seems to be different than the Optima SX. When people do a 0-60 run in the Optima, they hit 60mph in second gear around what looks to be 6000rpm, but mine is doing about 53 or 55 in second at the same rpm, and needs to shift to 3rd to hit 60.
One final note, although I would need to do some data logging to see if it is true, it does feel like the boost builds a little more quickly when starting in first gear in manual mode rather than starting in drive.
I will end this by saying I KNOW it is not a "performance vehicle", but I am a little disappointed I'm not getting low 6's from 0-60. I'm only at about 2100ft above sea level, 8430 miles on the paper filter, plus maybe 50-100lbs over the stock weight due to running board additions and a full stereo change. I only weight about 150lbs myself, so I'm on the lighter end of "test drivers".
To alleviate the "slowness" of this car (although it is still fun to drive), my plan is to pick up a LT1 or LT4 C4 Corvette next year, which will also curb my no-manual-transmission blues. The C6 will follow in a few years after
