The 2JZ-GE engine in the 2002 Lexus GS300 is rated at 215HP/218TQ. VVTi basically optimizes the timing throughout the rev range, so there is basically no flat spot. But a GS300 has about 3,600+LBS to tow around so all of its 215HP struggles to launch the car. It does its best in 4th gear past 100mph.

I used to be able to kickdown to 1st gear around 35mph in the Max and get a chirp. Even more so with the downpipe. Cold weather (40 or lower), I'd have to careful because I'd spin all the way to redline in 1st and part of 2nd gear on a 2-1 downshift. It was crazy TQsteer making me swerve to the right. I wish I still had that car :(

OK well the Aurora is 4000lbs stock....

As I remember correctly the GS300 only launches harder because it is RWD. Any FWD car will loose off the line to a close matched RWD car because of weight transfer ( most of the time ) Besides, like I said my dad has 112k and my frined has 30 k, and no VVTi or any of that techno crap. The GS in the summer can BARELY even chirp the tires from a dead floor, its low end isnt exactly crazy. My dads aurora pulls the hardest off the line......now coming to think about it my regal at about 10-20 km/h seems to pull the hardest out of all 3, then it dies out pretty fast.......and it only has 170 and 225 lb ft, I guess its where TQ peaks.

Speaking of the SC300, I have a really cool video clip of a SC300TT absolutely annihilating a Cobra Mustang on the street, it isn't even cool how bad that cobra got blown away. Also have a few supra clips, 2 clips he blows away both a CRX and a Saleen Mustang. But then in 1 clip he gets absolutely smoked by a Mclaren f1. I have about 55 clips of different races.

TQ to weight ratio favors the Aurora so a skill Aurora driver shouldn't have a problem getting a better launch if he/she can control wheelspin. The GS300 doesn't have enough TQ to get its arse moving with even a slight chirp so it basically bogs.

actually launching favors fwd, alot more weight over the front tires. the front end of the aurora doesn't really pick up or drop reall suddenly. even when i slam on the brakes, the front end dips, but not nearly as much as other cars ive driven, the car more like "squats" than dives, so there'* even less weight transfer when your taking off the line

Launchinhg doesn't favour FWD, although the weight is all up front, there'* all this weight transfer. If the Aurora was RWD with the same specs, it'd be a better launcher?

Crap? With variable valve timing, wouldn't you want more low end torque AND high end power? VVT can do that

I have a clip of a Merc E55 AMG, the new supercharged ones, just with street legal drag tires or something (I forget), annhilating an '03 Cobra, also the */c ones - and the Stang had mods.

Those '03 S600s, with their twin-turbo V12s, have what, 700+ torque at looooooooow RPM? Makes the Series II SC look... wimpy

... and yeah, that E55 vid - the guy did like two jumpstarts before the race could've been started properly

FWD is much more consistant than rwd. i have no problems launching the aurora at all, foot to the floor and go, no traction problems. if it was rwd it would be much easier to break them loose.

most fwd cars with a good amount of power like the ones you'd race, also have fairly tight suspension, so the front end won't pick up as much. (less weight transfer) GTP'* pull off some crazy 60' times stock, better than a thunderbird supercoupe, which engine has basically the same characteristics (less hp, but more tq)

if gtp'* where rwd it would be much harder to hook up. then again, you could put bigger meats back there, getting much better times, but apples to apples fwd launches better. my car'* about equal with my dad'* truck in performance (2000 sierra 5.3, ext cab, 4wd) in 2wd its hard to take off without breaking the back tires loose. its the "z71" so it even has a limited slip, he has wider tires, but i can launch harder and easier. our ssei which is really torquey, like the z71 launches much harder too.

if the aurora was rwd it would be a worse launcher, but much much funner.

when i was reffering to the front end dipping, i got sidetracked, talking about something
else, then i related it back to what i was talking about (i ramble on sometimes...hehe)
