Hey man!! whats up!? your theory is correct BUT only applies from a dig and/or a low speed start!! now when both objects are moving and starting an acceleration test from a high speed the weight is no longer a factor due to the momentum of both objects at a high speed!!.. i took physics, and i verified it with my professor!! its more then possible!! NOW lets get back to the build POINT of this thread!! --- _[View the full topic](https://forums.speedlife.net/t/ka-t-2jz-and-rb26-engine-build/114014)._
