If bringing your front tires 2 feet off the ground is not a monster wheelie, what is? I thought your were going to say 1 1/2 to 2 inches ... just for the sake of getting the wheels off the ground..

either way.. lol.. Good luck.

Can't tell 100%. But I like to think the passenger tire is up in this pic.

cut the guy some slack sometimes u want to know you can fly but the work required to make that happen is just not worth the result, if you are really set on this then raise the *** end put some tractor tires on it and bounce around all day!

but here's your answer…good luck...

lets just say your car is uniformly distributed load of 3400lbs (wet with a driver) from the rear wheels forward…and lets say from the center of the rear wheels to the tip of the front bumper is 12 feet…

lets assume the car is completely horizontal and the load is applied to the center of mass…

3400lbs x 6 ft = 20,400 ft*lbs of torque required to bring the front wheels off the ground…

I'm sure somewhere someone can make you a blower that will create 20,400 ft*lbs of torque…but your next challenge is finding tires that will lock up to hold those 20,400 ft*lbs...

actually my friend it's all about dynamics. your statics model assumes that the car does not move forward at all. The momentum created when the car moves forward and suspension geometry shifts plays a large role. drag radials twist under heavy load like a watch spring in order to decrease the sudden impulse associate with drag launches. when this potential energy is converted to kinetic it can help the car get up on it's wheels.

I realize you were just trying to make a rough estimate as to the power required, but I'm sure you realize that the weight of cars is not a uniformly distributed load and cars such as the z are slightly nose heavy which would make your answer even higher.

however most cars are dyno'd in 5th or what ever gear the input shaft to the transmission is 1 to 1 with the output shaft. the lower (smaller radius) gears (where you tend to see cars do wheelies) multiply the engines torque by quite a good bit. If you dyno a car in 1st gear you will get much higher numbers. that being said even if a car made 1000 ft-lb at the flywheel it would need a 20:1 gear ration (including final drive) in order to make 20+ kip-ft of torque

in reality I've seen cars making as little as 900 RWHP do a wheel stand so order of magnitude analysis would disprove the statics model.
