I'm the type that has to makesure the vehicle will do what the speedo number read. Buried the needle in a 65 mustang past 120, hit 132 in a 4 cylinder Camry had to back off and didn't get to 140. My toyota truck 110, I bought my son a 350z but haven't had chance yet to many curves although the curves are fun. Going to brake the chain and not try the wife's Mini Van.
