I dont know if this has been discussed before but my bother and i were having a conversation about how he took his porsche on one of our local highways and hit 185mph, the discussion turned over to my car were my brother said he was pretty sure that my top speed would be around 160-165mph based on gearing NOT horsepower. anyone know what a '93 rx7's gearing will let you go up to in speed (considering you have the hosrepower to bring it to that speed)?
