What level of modifications produced that time?
My 400EX in full cross country trim (i.e. heavy) produced 9.599 @ 66.86mph - (not a stock engine)
My C-Dale in 100% stock trim produced a run of 9.476 @ 68.19mph
I haven't had my 450R to the paved strip yet -- but I have had it at a 300' dirt strip many times.
