I had my r32 GTR on 2 Dyno's

At croydon at all 4 wheels it had 139kw

At Unique Auto Sports it had 178kw at the rear wheels at 11psi boost (same as @ croydon)

At Unique Auto Sports it had 208kw at the rear wheels at 14psi boost

The only other mods the car has is exhaust and BOV.

So at Croydon, where it made 139 awkw you were also running 11 psi boost? 40 kw seems like a big difference even taking into account the difference between 2 and 4 wd. Did you quiz them at all?

Yeah I had 11psi boost at Croydon. I had only recently got my car so I was unsure of figures. They told me that was a fairly normal awdkw figure for a GTR. I thought it was a bit low thats why I had the car checked at Unique.

This is really interesting. Prior to purchase I had my car dynoed at an independent 4 W dyno shop here in Canberra and it pulled 180 awkw. Yesterday at Silverwater Auto Services who apparently pride themselves on the accuracy of their dyno it pulled 130 awkw.

I know dynos aren't dynos but given that both runs were on the same boost, about 9 psi, this presents me with a bit of a dilemma because I don't know if there is a problem or not; 50 kW is a hell of a big drop although I note that it's about the same as the increase you experienced going from four-wheel to two wheel dynos. I really don't think it it was in 2wd mode the first time but it must've been.

Did the guys at Unique say anything about whether they felt that power readings there were fairly typical of what your car should be producing?

does your car feel like it has lost a shitload of power since u have had it??

coz im oretty sure u would feel that sort of power loss?

Bretto;

No I didn't notice, I agree that I should / would have. But I suspect that the dyno here is optimistic.

Good news is that the problem has been found by the guys working on it. Would you believe the throttle wasn't opening all the way?! Checking for power loss Rule 1: Is the throttle opening fully? I guess neither they nor I believed that it could be the case but...there you go. Latest reading is 168 AWKW at Silverwater on standard boost ie .7 bar and with an exhaust. Doesn't explain the difference in inital readings, but I'm happy to put that down to an optimistic dyno here.

Thanks to everyone who responded.

i thought the figure was about 140 awkw standard. My r32 GTR started with about that figure then i added a power FC and full 3inch exhaust and got it tuned, gave me 180 awkw then i fit an AVCR, HKS filters and screwed it to 1bar boost and it gave me 210 awkw. I also read that GTR's pull 140 awkw in standard form in an issue of Hi Performance Imports.

    • Hey guys, I have dipped my toes into the pool of skylines finally and figured I would get amongst the forums and make an introduction post! My name is Callum, I'm from the north side of Sydney, and I am now 6 months into owning my 1992 R32 GTS-T (already having half of that time off the road in true nissan fashion). It is originally an AH3 car but at some stage of its life it has been resprayed in and out in TH1 with (in the sellers words) extra purple, parked next to an actual TH1 car it is a fair bit lighter in colour. It has also had the original RB20 swapped out for an RB25DET NEO which I presume to be out of a Stagea going off the AWD sump that has been sealed up. I won't go super into detail with mods as I want to create a build thread post soon. Unfortunately the car seems to have had a hard life as many of these have being previously a cheap sub 10k car, and I have barely any history on it so if anyone happens to recognise the car or thinks they may have any history I would LOVE to hear it as I am a bit of a nerd when it comes to car history, the seller had it roughly since 2020 I believe and was from Parramatta area if that helps. Look forward to being a part of the community, I have been to 2 SAUNSW events already (one being in 2022 prior to ownership, and once more a few weekends ago) so you could say I am not brand new to it but can definitely be more involved via the forums! (side note: I am pretty new to forums and struggled to attach pictures of the car, is there an easier method than having to have the pictures on facebook and copying the link from there? would love to know for future reference cheers!)
    • I have GT2860R. I'm not sure if they are -5 or -7. Do you know? These are the exact ones.  https://www.enjukuracing.com/products/garrett-rb26dett-gruppe-n-turbo-upgrade.html?srsltid=AfmBOopSCzHaDtf7nggL6R8KrD8RJP4wxBJitmkRmswmv2SaEbAVcxTe And to be honest, i think the car was the most enjoyable to drive on the streets when it was 280hp (205kw). I could enjoy all the revs to redline i wouldn't be going crazy fast, but just fast enough to know that you are working the car.  
    • If i used a cooling system pressure tester, would it show me a leak with the head gasket? Ive used one before to chase down a leaking coolant hose. Not sure if this will work on the oil-cooler warmer. 
    • Hi all,   suspect this is a common problem. I think I missed 4th gear a bit when I shifted down from 5th. Now it grinds into 4th with the downshift. Is it the sychro and what do I need to replace when I open the gear box up?    added a photo of my new titanium intake I just installed and built. 👍💪
