Guys I am confused!!! Soxx's car ran a 14.4 at wsid with 173 rwkw
and Loxxr6 ran a 14.68 with 141rwkws.......

Soxx is running dev 5 head cam xorst and a nice 9inch diff.

Loxxr6 is running an unopened xr6 hp au unichip..and xorst

So why is there so little difference?Maybe these drivers can enlighten us as to why?

Dellboy999

what diff ratio, and what gearbox ratio, what gear did they cross the line, what was the 60 foot times.

Check my sig for that info.

My times came down to dumping the clutch at around 2000 and hanging on. That and pure luck haha....probably.

Oh and its a manual.

Too many variables to condend with. Weight, gearing, launch grip, gear changes, track conditions, temp, etc etc.

I *think* the cars were comparibly similar in weight.

I never changed out of third gear when I did all my runs @ WSID except when I botched second to fifth....

Also alot of difference in the way the 2 drivers launch...

Also don't compare dyno printout's when comparring two different vehicle's, they will be different on different occasion's, there is to many variable's to take into account here.

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 14.4@96.5 173rwkw 4th gear 32.7Kmh/1000rpm
Loxxr6 XR6 Series 1 manual Sedan 1540kg 14.7@94.6 141rwkw 4th gear 32.5Kmh/1000rpm
jonbays AUII Fairmont wagon Auto 1650kg 15.6@90.1 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.

It appears to me that dynos mean nothing...Id like to see the times with a dev 5 and unichip if anyone has them..

useless

I agree totally Casper but Rick had done his best time there so is Loxxr6 just lucky?I would find it hard to believe...Loxxr6 has got to be stoked with his results
