The run up to see the Tucson guys will nail down your car weight for sure. I am guessing the MK2 FFR comes in close to about 2400 pounds max. That is with a driver and as you drove it to the scales. John am I close or can you help with a more educated estimate? Until we hear different lets use the round numbers of 2400 LBS.... maybe a bit high?

The web is full of huge HP claims but a quick scan showed me engines with your goodies averaged from 350 to 450 HP. Found one guy claiming 535HP but had very worked heads and more goodies. I know it is all just chatter until you get the pulls on paper but ballpark numbers at least. If she weighs 2400 LBS and use 350 Hp minus 15% drive train loss then you get 297.5 rear wheel HP so 8.06 pounds per horse and @ 450 hp - 15% = 382.5 and 6.274 LBS per horse. 8 .06 or 6.27 pounds per horse is pretty respectable.

A Shelby GT500KR with advertised 540 Hp minus the same 15% = 459 HP and at 3900 pounds tips the HP per pound to 8.49 LBS per pound. The Shelby is supercharged and uses advertised HP but bet it is a real number. Just bench racing but the numbers are a hoot to compare. The old days you were lucky to get over 1 horse per cubic inch to the wheels and that is in a tank with a zillion pounds.
