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.

    • Well, I'm not clicking on a link to f**king bookface (never have, never will), so I can't really know what the complaint here is about, but.... There's nothing particularly wrong with forcing people to have a higher license category to drive super/hypercars. Note that the laws are not about modified cars - only listed standard cars, because there are not supposed to be cars modified enough to meet the law's category limits anyway. If you have a modified car that falls into those power limits you're already in trouble anyway. What is wrong is the bullshit on-line "test" to get the upgrade, instead of any actual work and training.
    • Meh Don't have Facebook anymore but watched a YouTube about it, they also talked about them not being able to use and "sports" modes, not really sure how they would enforce that apart from logging the Db for the cars that have exhaust valve activation in sports mode Apart from all the high end sports cars and supercars that make the sort of power they are talking about standard, I cannot see it bothering anyone else, unless of course road side tests now include having a dyno and scales on site to test the power output vs weight What is it? 500hp per ton? And if the only additional cost is $60 or so, as the video stated, I cannot see that being a war stopper for the people that outlay a few hundred thousand dollars on a performance car In fact, I see it would be a ego boost for some, because they have a "special" drivers licence for a "special"person with a "special" car And if I did have a modified car that made over the limit, there's no way in hell I would apply for a "special" licence, I could see the authorities checking your licence against your rego, so if old mate applied for a licence, but owns a, say, R33 Skyline, that may trigger an inspection of said car as to why, and how, that old mate has a R33 that would fit the bill of making over 500hp per ton Again, meh, not something I believe will be a real issue to 99.9% of people

    • Hi, I'm a new member who has been lurking for a while. Ive been looking to buy an R32, 33 or 34. GTT/GTST for some time now. I'm close to pulling the pin on one,. My question is around roadworthy certificates in Victoria. What can you get away with as far as mods go?  Would a car pass RWC with a haltech dash, aftermarket manifold and high mount turbo as long as ride height and noise was ok? I come from a muscle car background, I'm learning more about our beloved Skylines as I go. I don't want to drop my savings on something to find out I need thousands to get it on the road. Cheers for any input/advice.  
    • The first year I did Putty Road I was driving the old Honda Jazz work car. Being the rear vehicle of the 2nd or 3rd group to make sure no one got lost. The GTRs in front couldn't work out how I "was with them in the twisties"... They didn't like it when they found out I was only cruising and chilling in the Jazz like it was a Sunday drive with my Nan in the car.
