I hope the link works. If it does if you guys want to figure out your scale speed by this chart and your car info we can compair performance. Then we will have a better idea of what makes for better performance. That is if we are honest. Please post your results here.

Scale speed By chart
 

At 20 ft my Skyline took 1.72 sec. on average Not the best speed not the worst.
Acording to the chart That is a little better Than 136.6 mph. That is at 1/24 scale speed but still cool. Im not sure but I think that equals 5.69 actual mph.
I also have to keep in mind that the differential is slipping on one of the axles so it may get better after I fix that.

try glueing the diff on the inside to lock it up, it's kinda like having a posi it will give way better traction, im sure there is a post on how to do it, just search, well worth it imo
