On a straight drag track the OCIR track, doing every start the same way (holding on to the up arrow) here are some of the speeds.
USA 1 13:33
Virginia Giant 13:36
King Kong 3 13:39
Big Foot 5 13:41
Grave Digger 20 13:47
Bigfoot 8 13:50
I dunno take that for what its worth, and as i said on a track with cars Warrior seemed way slow, and Bigfoot 8 had the best control.
Every truck is the same, in speed, acceleration, and basic handling. The only thats different however, for example Outlaws new Bigfoot 8 is set spongey, meaning the truck leans while it turns and gives it more control according to your preference. In all actuality the trucks are the same and in no way does one hav an advantage over others.
Its in the matter of how you set your truck up, You can adjust the setup in which can modify the control/acceleration and speed (by gearing), its all in binedit. You can make a truck have better acceleration with a less longer wheel base, You can make a truck turn better with the truck being lower to the ground. All trucks are NOT the same. They start off the same but its all in binedit and how you drive them. Depending as I said, on the setup some trucks DO have the advantage over others.. You won't see many long wheel based trucks winning on short drags, but you will see the short wheel based trucks excelling at them. An you will not see many stock type handling trucks beating out "Sponge" trucks.
In summary, all trucks are not the same, you can create your own set ups that stick to your driving style better, as well as modifying the truck to excel at certain type of tracks, and aside from stock handling trucks. There are no trucks the exact same
P.S its is not Kozaks Bigfoot 8, its Scotts.
