Well overall it was pretty good for the YFZ. The YFZ beat the DS off the line. I will get videos of this for you all tomarrowThe DS did catch up after it got topped out. However I did not have the YFZ topped out because there are only 3 hours on it so I did not want to hold it wide open for too long. The YFZ had the DS off the line by 2 quad lengths. Top speed it is a little hard to say but I believe the DS is a bit faster. DS though are faster than raptors and beat them off the line stock for stock so I bet the YFZ will be able to take Raptor! I will have a drag against a stock raptor and a CT Piped Raptor tomarrow night. The YFZ just kept pulling away from the DS until the DS got topped out.
