i can get 50mph tops on a level road every time. downhell i´ve had 63mph before i run out of road. i find that once i get past 45mph she starts to scream. past 50mph she starts to really shake. my scv can giv some 125´s a chanllege when it comes to acceleration as my friend found out when he tried to race me. do you happen to know how to de-restrict and scv?
