Torque =???

[simonm]

I am going through the motions with a new van, i have 2 options

 

1 120 bhp 300nm torque

 

2 150 bhp 375nm torque & add blue

 

It will spend its life overloaded and towing like every other arb vehicle, so the more power the better...but...what can i compare the extra 75 nm of torque to? the power of 75 cats pulling it? or 75 rocket engines or anywhere in between?

 

If the difference is hardly noticeable then id rather not have the extra cost of ad blue! any ideas?

Torque is force x radius or turning force . Torque is of great value I think . Imagine a 300hp tractor verses a 300hp sports car . on the flat the sports car wins . Ask them both to pull a full grain trailer and the car will struggle big time . So if you dont want to go fast but pull heavy loads its torque you will benefit from . If you just want to get from A to B quick then ........

Stubby`s on it, torque turns wheels. HP is pub talk to impress mates

 

Edit. Torque and where its made in the rev range are where you need to be looking. Torque is worthless if you need to scream the nuts off an engine to achieve it.

I understand torque is the pulling power, i just dont know how much difference 75nm of torque would actually make, or what to compare it to.

More hp and torque is better, and adblue isn't a major headache. Most garages sell it now and trucks use very little of it.

[Jimwilli]

With my extremely limited mechanical knowledge your looking at around 20% more on both hp and torque between the two.

 

How that directly relates is beyond me.

[cornish wood burner]

375nm =276 ft lbs

300nm =221 ft lbs

so 55 ft lbs more

Fiat 500 twin air is limited to 100 nm in eco mode more in normal, if you want a small car comparison

Hope that helps

75nm is approx 7.5KG force metres. So the difference is the equivalent of putting an extra weight of 7.5KG one metre from the point you're trying to rotate.

 

Not really sure that helps, reading it back!

You can bypass the adblue system anyway

Hi

 

Stubbys reply is spot on

 

Torque is turning force in either Newton metres or foot ibs, thats the same torque as in a torque wrench.

 

The more torque an engine develops, then the better it will be for towing
