Just Had My Car Nistuned With The Z32 Ecu, Just A Question About The Torque

[ryan101]

i just picked my car up it a rb25det stock everything except exhaust and fmic and boost contoller running 11psi and now nistuned ecu

last time i had my can on the dyno ( everything was the same except the ecu and 10psi ) it made 325nm and this time it made 567nm, my questions are does that sound like too much and would nistune plus 1psi make that much of a difference?

the rwkw was 186.4 last time and 187.9 this time, im not complaining just wondering if thats an error or if is sounds right?

Peak torque readings from a dyno graph are pretty meaning less unless some one sets it up correctly.

In your case the new figure of 567Nm is wrong due to not being set up correctly.

This is pretty much part of the large debate happening in the other "peak kw" thread lol.

Damn thought I had something special lol

What would be a safe nm of torque for a stock rb25?

[PM-R33]

From factory they are rated at around 319Nm.

My friends R33 GTR recently made 400rwkw, and apparently made 1800NM hahah. I would take the torque figure with a grain of salt.

thats tractive effort.

The kW rating is related to torque by the following formula: Torque Nm = kW x 9550 divided by rpm.

You torque is the power at any point, divided by revs x 9550.

Then you'll have to work out at the engine, which is about 20 to 25% extra.

I'll guess with 11psi you have peak torque of (240/16)*26 = 390Nm

using your calc i make it out to be ~450nm at around 4400rpm
