well i just raced my buddys attack, and its nose to nose, he has more experience lauching than me, so if he took my srx and me his attack it was dead even un to 180km/h (lake wasent long enough to continue) If i took my machine, and he took his attack he'd get my by a sled on launch and pull a little after. My srx is bone stock (for now hehe) except for minor clutch mods suggested by mr viper. So with some work it can be done, also the conditions yeserday werent good for me, 5celcius above zero and slushy snow, all to help him.
