Unless the Huracan comes out with aero and tires similar to the ACR (which also has 650hp/610lbft), it's not even going to be close without massive weight reduction and/or significantly more power.

918's lap would be much higher if you cut it to 650hp and 415 lbft (which is probably what the Huracan SL is.

You can't compare a racecar setup to a 918. Of course a CS will be very fast. Change the suspension back to that of something you could actually use on the road car though, and it will be way slower.
