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.

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

      That looks good, but I think you're going to need much beefier side skirts now.

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
