Theoretically , what would be the top speed of a 1,000 crank horsepower 7 speed Manual (1LE ) package Z06 ?
I have a friend with a Suzuki Hyabusa that thinks his bike is the be all and end all . I know these bikes are fast , his even more so as its been Turbo charged .
Just looking for info so i have some ammo for back up

the biggest factor on a turbo busa is someone who can get the power down without looping it / wheelspinning etc.

Impossible to say for sure without knowing the bike's specs - how much boost what tyres etc etc.

WHo cares though, he loves his fast bike, let him be happy till the day he gets smoked by someone faster.

Point taken , however , i would still like to know what the top speed of my car could be /is

You and your buddy could go to this event to test your theory and hope not to be a Darwin Award winner trying to prove out your theory

this z06 with an xpipe but otherwise stock so the owner says— went 204.

For the Hayabusa, it depends on how much power the bike is making, but bikes are aerodynamically poor, so it takes a lot of power to achieve high speeds. They were reaching 235 mph top speed (in less than mile) about 10 years ago, Since then, the limit of power has gone from around 300 hp to 500+hp, with top speed increased to around 250 mph. With cars at high speed, there's the risk of blow over, although assuming the Z06 has enough front end downforce, this shouldn't be an issue.

As for the Z06, assuming stage 1 aero, top speed is about 195 mph with 650 hp (according to Road and Track). Top speed increases approximately with the cube root of the increase in power, so 1000 hp would translate into about 225 mph. Gearing would need to be changed, as 225 mph is redline in 6th gear, and 7th gear is too tall.

Even a stock first gen Hayabusa, making about 160 rwhp with total weight of bike and rider a bit less than 750 lbs, translates into a Z06 making 800 rwhp, with total weight of car and driver about 3750 lbs.

I have a Callaway 757 M7 1LZ with stage 1 aero and was told by Callaway that the top speed of the 757 with stage 1 aero is 212 MPH. I don't know how much more MPH you would get with the extra 250 HP but it does take a huge amount of power to get very small gains at those speeds.

According to him , the bike is making 300 to the tire !!!
I know its fast just wanted to know or find out what speed the car would max out out .

In terms of power to weight ratio, that translates into a Z06 with 1500 rwhp, except, the turbo busa will be wheelie limited until around 150 mph. MotoGP bikes are around 260 to 270 hp, and limit power until around 150 mph, but they're much lighter than the Busa, which is why my guess, the Busa might be able to use most of that 300 hp at around 150 mph.

Bikes are aerodynamically poor though, so top speed will be somewhere between 240 mph and 250 mph, and reach that in not much more than 1 mile from a standing start. A 1000 hp Z06 is going to take more than double that to reach it's top speed.

Thanks , i know its one thing bragging how fast a Car or Bike is , however , trying to hit those speeds takes some nerve . I would imagine more so on a bike .

One advantage of bikes is there's no chance of lifting (or worse yet blow over) as there is with a car, as there's nothing to trap air under the bike's fairing, and the front end of the fairing produces some downforce. Turbo Busa's with stock fairings reached 235 mph about 10 years ago. A moto gp race bike recently (June 2018) reached a speed of 221 mph at Autodromo del Mugello (Italy) during practice for the closed circuit race. I seem to recall that even modified, the C6 Z06 had a speed limiter set to 205 mph, which would provide some margin below the speed at which there was a risk of lifting. I don't know if the C7 Z06 has a risk of lifting enough to lose traction at either the front or rear end at some high speed. As a bad example, the original Audi TT had 148 pounds of lift at the rear end at 125 mph, enough to create incidents on the Autobahn. Audi added a rear spoiler and tuned the suspension for understeer to compensate on later models.

An example of RX7 at 215 mph, lifting the rear enough to lose rear end traction and spin, then flip over. No sudden stop, so driver was ok, and deployed chute near the end of the video.
