Hey guys

I got my car dynoed again today and I just want to try and clarify the difference between rwkw's and 4wkw's on GTR's.

The last time I got it done on a rwd dyno and it came up as 253rwkw at UAS.

Today I have the same mods as last time but just adjusted the boost response i made 257kw @ all 4 wheels at CRD.

Now Jim at CRD said to me the difference between rwd and 4wd is around 30kw give or take and that sounds a bit too much to me. When i tested my car today, it felt like maybe at max an extra 10-15kw at the wheels difference(but thats just my judgement). I also read somewhere here people were saying around 4% difference between 4wd and rwd for r32gtr's.

Also last time my stock injector duty cycle at full power were at around 80-82%.

Now Jim reckons I wont be able to make anymore power safely because of my injectors maxing out which I assume would at least be 90% plus? But need to confirm this later.

Stock injectors max out at around 280rwkws or so?? So does this make sense to assume its around a 4-5% loss between rwd and 4wd? Opinions wanted please!

Cheers

I had my car dynoed at Melbourne Autosalon in both RWD and AWD within a span of 24 hours of each other and no changes were made to either the dyno or the car except for the removal of the driveshaft.

In AWD, my car made 604awkw and in RWD, the car made 617rwkw.

Regardless of how the dyno was configured intially, all the settings for both the dyno and the car remained the same. The only thing which changed was the ambient temperature and humidity in the Melbourne Exhibition Building which would be considered as negligable.

Hope this info helps.

    • Cats are called Bella, and Donna...  Like that poisonous plant And I remember your 2 monsters, I remember making a little bit of wee when you let them out... LOL I have already installed cat doors into the laundry where their kitty litter is, and the sun room, apart from the cat doors there's not going to be any permanent mounted stuff on the interior walls (interior doors are cheap and easy to replace) I will get a outdoor cat cage thingie once I finish the landscaping out back... https://catnip.com.au/ The only off limit areas are the main bedroom and the gym room....but, currently the cats are curled up in bed, in the main bedroom with the Mrs.....LOL, the off limits for the kittens to the main bedroom lasted about 5 minutes with Jackie I currently only have 1 free standing huge cat tree multiple level scratching post thingie in the lounge room, but, I will be getting another one soon now that I'm happy with the furniture layout in the back room and have a perfect spot for it  
    • All of this is making it seem clear that running the Coppermix twin was definitely the way to go, especially in hindsight with how insane tariffs have gotten and the strength of the USD vs yen at the time.
    • That sounds like no chance of even importing one for road registering then Now I see why Duncan wants to check LHD rules for Targa...   I wonder how "bolt in" the AWD would be if you got one imported from the US and swapped it to an AUD one
    • Not to mention they drive like a bucket of bolts! yuck!
