Message	Smacking rev limiter and high rpms is hard on the motor. Should always try to keep it up high enough to spin but not super high esp in those conditions where there is no load so to say on the motor. Its like free revving almost. 1990 Acura Integra (Daily driver/Gas saver) 1994 Nissan 300zx Twin Turbo (Weekend car) www.SVZA.NET
