I have noticed that Nismo's tend to dyno a bit higher with the same mods, relative to non-Nismos. Initially I thought this was due to different VVEL tuning, but it seems as though they are not different (or there are as yet unidentified other tables in the ECU to play with).

Now my thought is that this is probably more likely due to noise (random differences dyno to dyno reading) and that some of those non-Nismo dynos were on modded but untuned cars.

I can confirm that the OEM H-pipe and catback is MUCH better than either the OEM non-Nismo or Weldina Nismo Y-piped exhaust.

Wut about S-Tune exhaust? Eh?

What's the difference between HP & Torque in real world driving. The 370z has the same torque as the old one but more horsepower? So where would one experience the difference driving

In a nutshell, torque gets you off the starting line and HP gets you across the finish line.

If your getting the Nismo for more HP your doing it wrong

"Where horsepower determines how fast a vehicle can travel, torque at the wheels determines how quickly that speed can be reached. The greater the torque figure, the faster the acceleration."

HP sells cars, TQ wins races :tup:

Extra horses come from Momma horses...... Just sayin.

lol, none of that is true.
HP=(RPM * T) / 5252

A car with high TQ relative to HP simply means it doesn't rev up as high as should.

How fast a car accerates, after the car has passed 5,252rpm is a funtion of THE AREA UNDER THE CURVE. The curve a function of the rpm ranges as dictated by gearing.

This is why something like a 290hp NSX with much less TQ, destroyes a 370Z in a straight line.

Torque is only useful really for 0-60 times and trucks that need to pull things.
In sports cars where you're in gears 2-6 much more than gear 1, HP is much more important.

Sorry, I wasn't clear.

S-tune = Weldina = Nismo Y-pipe = Crap.

The Nismo "take-off" exhaust with H-pipe is MUCH better in terms of power and quality.

Both sound good, but power aside, I kept getting cracks on the S-tune Y-pipe that needed to be welded... terrible :shakes head:

Eh... not exactly... as something of a rejoinder: "HP will win the race, while TQ puts a smile on yer face" :D

Lol @ tq is only useful for 0-60 times. Really? So after that, tq isn't a factor?

OP, watch this... it can help you understand TQ and HP relation
