Why is it that a engine making say 600HP naturally, is easier on drives than a supercharged engine making 600HP? I'm just curious

The supercharged engine produced considerably more torque than the naturally asperated engine.

Chris

What is your torque on your supercharged engine?

Mark

Torque is what breaks stuff....most of the time. Alot of supercharged engines can have the same horsepower as NA engines but, the supercharged engine will, a lot of times, have more torque than the NA.

I believe that my 600sci, which is rated at 600 hp at the prop, produces around 800 ft/lbs of torque.

Chris

and the TORQUE comes in like gangbusters!!!

Blower motors always produce more torque.

That is why a blower boat will always out accelerate an N/A boat even if HP is the same.

Forced induction motors of similar peak power will have a ton more area under the curve....alot more torque across the lower and middle RPM's and more peak torque as well. You need a much better breathing N/A motor to make similar HP because its simply relying on much less atmospheric pressure to fill the cylinders....

As others have already mentioned....boosted motors come on harder and to directly answer the OP's original question will have a far easier time breaking parts than a similar output N/A application which will never hit as hard.

However, a blown SBC compared to say a well designed large cubic inch big block will be very similar in torque and power output and in that situation, the larger N/A engine might even be worse because it wont even need fractions of a second for boost to build.....it will hit like a freight train instantaneously.

But this argument only applies to a much larger displacement N/A application....when discussing the same or similar CID, the blown motor gets the nod for breaking parts....LOL
