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

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
