Some good answers above. My torque is around 450, its still manageable with 275 tires. At low boost, 380tq you will still have full control with same tires.
To expand on this a little further.
Torque is what pushes the car forward. HP is a sum of torque and rpm.
What matters more than anything is the torque curve.
A car that make 550hp but has a steep torque vs a 500hp car with a flat torque curve.
The 500hp car will be much faster and also more challenging to drive "tire spin"
How many of you drive you car at redline? HP is a measurement at or very near redline.
vehicle weight will also have a influence over drive-ability. The heaver car will need more grip for the same amount of torque than a lighter car.
While I'm going down this rat hole... Driveline mass will also have a influence as well. But this isn't measured directly by a dyno. It effects rate of change.
A supercharged car that has low end torque vs a turbo setup that has steeper torque curve will drive differently.
My car only makes 440 rwhp but 300 fbs of torque at 2000 rpm. it will spin the stock rear tire all day long.
I had to go to a good 285 rear tire and still can't get on it with the Traction control on.
The car weighs 3000 Lbs with a very light drivetrain
If my car made 100hp more i don't think it would be usable on the street. On the race track that is a different story.
