    Re: Finally: G-Tech performance results for '02 996tt!

    I must say that I am a bit suprised by how well the M5 did. It must be the new 500 hp version they tested. I can't believe a sub 400 hp, 4000 lb, 4-door car whipped some "real" sports cars. My brother has an '01 M5 and it is fast and all, but I don't see it doing that well...

    Thanks man,

    I hopped on the C&D website, and it's a May 2005 review. Basically, they compared 7 items priced under $1,000. Some were accelerometers as we discussed (using an electrical field in the unit that detects change during acceleration). The G-Tech Pro RR has an accelerometer that measures vertical plane acceleration, important, since during hard launches, the car's (a Pontiac or GMC Envoy ) tail tends to squat and the nose can lift (wheelies! ), so acceleration 90 degrees from gravitational forces is more accurately measured. One uses the GPS system (the AX22). They concluded that some, including the G-tech, are reasonably accurate, and they liked the G-tech! The VBOX was the "gold standard" equipment for C&D, but pricey.

    I just watched the Ultima 0-100-0 videos. That's amazing stuff. He makes the perfect launch, only uses 2 gears to get to 100, then brakes without ABS (I assume) with only a nary of lockup at the end. It does look like he stalls it at the end, though! That's quite a car!
