Re: 173 vs 141 rwkws times 14.4/ 14.6????
The dyno's are just not that good for comapring these cars.
I ran with these guys at WSID and look at the hard facts that I know and can vouch for:
Soxx's ute manual 1600kg email@example.com 173rwkw 4th gear 32.7Kmh/1000rpm
Loxxr6 XR6 Series 1 manual Sedan 1540kg firstname.lastname@example.org 141rwkw 4th gear 32.5Kmh/1000rpm
jonbays AUII Fairmont wagon Auto 1650kg email@example.com 142rwkw 3rd gear 33.7Kmh/1000rpm.
If you accept that the 400m is all about power to weight modified by gearing and launch then its clear the manual XR6 sedan has the best launch and the lowest gearing so its going to go well. Soxx's ute rear leaf springs are too hard compared to the XR6 springs even lowered. The terminal speeds tell us who has the power though soxx's extra 2mph doesn't sound much but it means that its got much more power. The wagon compares badly but its the heaviest an auto with only three gears and all of them higher than the others so its not surprising. puting the terminal speeds and weights into tci calculators I get 192kw for soxx, 175kw for loxxr6 and 162kw for the wagon.
The basics are power, weight, gearing, traction and launch. Dynos lie a lot too. It would be intersetng to see the cars on the same dyno same day.
