That is funny. My car on 24lbs(550whp) started to to ruin the clutches in it. When i would go down the track the car would keep changing power from one wheel to the other. Like an open diff peeling one tire down the track. Yes quaiffe is the best and it has a lifetime warrenty. What do you think they told me when i called them and told them my quaffie wont work with my 26 inch slicks and over 500whp? It is not designed for those power levels let alone 700hp. Just like your car a clutch can only hold so much power. The power is going to break the first weak link(quaiffe). 700hp on any diff will flat out destroy it. 700hp will destroy a whole tranny. I will show you prove after i destroy mine.
