Was a shame I only made it right at the end of the day, but still put the car on the dyno and had a bit of a chat with Jamie and a few others that were hanging around.

i dont know if its 40kw out or a certain %. My friends 100% standard evo 7 made 150awkw. Does that mean its got closer to 190 with a standard exhaust and standard boost?

A stock standard Evo will not be able to make 190atw. It's probably around the 170ish mark or high 160s.

190kw will require stage 1 mods and increase boost.

However, as many have said, different dynos have different readings.

Hey Antony! I PM'd a pic of your exhaust.

Got some last minute pics.

More so about 145 - low 150ish.

Thanks for that mate, definatly explains alot :blink:

No worries buddy! :D

Yeah thats about right, well at the Kamikaze dyno day, a stock White EVO 7 I saw made about 150 awkW's.

Cuz me and afew friends put a bet on see what it will make and I said 150kW. LOL!

but yeh 200 is easily achieved with an exhaust/cai, ecu and boost.

I was there also (had to go check up on my car thats been sitting there.)

Theres too many variables when it comes to dyno readings so the debate would never stop.

Interesting.

A comparison between my dyno RE Customs and Kamikaze is only 15kw difference.

I logged my run and I attributed it to the fact I had bad fuel and knock.... I've been on holidays for a month, hence the bad/old fuel.

I made 207kw at Kamikaze and 222kw at RE.

The plot thickens =)

Came by at the end of the day and was pleased I could get my car on & off within 20 minutes - no waiting = happy :(

Car is pretty much stock, just a catback exhaust. About 150kw, 11psi MAP reading (my boost gauge reads about 13-14psi, so which one do I use as the accurate figure? Boost restrictor's in place so I figure the lower reading of 11psi is probably right). I figure about 150-160rwkw is about right for a standard gtr, unless someone tells me otherwise?

So you are saying that Dezz's car with a GTRS, injectors, 18psi, etc is really only making 218rwkw. Only 10-20rwkw more than most R33's with std turbo; i really don't think so :(

Or my setup, that is maxing out a 500hp turbo can only produce 284rwkw; highly unlikely.

The dyno is very low reading, but what i thought was consistent, so not all is lost as you can still compare mods to rwkw, between other cars.

Just for the record, with my previous setup, it was dynoed on 3 different dynos (EAS, Autosalon and Racingline) and the 3 read-outs were within 7rwkw of each other. So i am very confident that the EAS dyno is reading accurately.

Maybe it was the way they strapped some of the cars down. My car was strapped that hard that the tyres were well into the guards. This does not allow the car to "climb" onto the front roller and thus will lose traction. With some other cars, the guy running the dyno kept re-adjusting the straps, not sure why he didn't do that with mine as he even commented that the car kept losing traction and the graph clearly shows that at 5300rpm. The other guys that did most the strapping really had little idea, as the main guy kept fixing the straps, when he cbf'd.

same with my car

garrett turbo, 19psi, injectors, pfc etc and making 180rwkw??

i highly doubt it

edit: like i said before standard/standardish cars were making roughly the power they had, where the more powerful cars were down

As long as you use the same dyno to test, thats all you need to worry about etc.

I could get you all a 600rwkw graph for mine, or one with 120rwkw... big deal.

As long as your tuning on the same etc to notice differences, all you need to worry about.

Dyno days are good for a cheap 'check' of AFR/Boost etc

Like @ Dr. Drifts night, i was on 15psi, i thought i was on 12psi, obviously something has changed i need to look at :(

Problem with dynos is that there is no uniform rules on how they should be run etc etc...

whos to know exactly which dyno is the "correct" one.

go run a mph at the strip it will be a good indicator of whether your power is accurate or not.

I disagree. We're talking about legitamite dyno runs here, not temp sensors stuck near exhausts etc.

You can argue that the results are comparable to other cars run on the day, but even that can be disputed (see Aj's vs nick's for example) but at the end of the day you can't argue that that the dyno was giving low numbers for cars with normally decent power.

Hi all, thought I post my result, my car did 140kw on the day its a stock R34 GTT with std boost, only mod is exhaust not full exhaust system, and pod filter. I thnk wen i put on the Sau sticker i got an extra 5kws on each side. :blink:;)

Either it was my first run and the day was great fun, nice 2 meet some of u guys. :)

I was told the dyno was running low on the day at Kamikaze... But ppl are debating weather it is or not...

Friend of mine ran his R32 GTR, which was stock (air box, exhaust, cat and boost) all factory.

He got 155kW at all 4 wheels at RE Customs back in March 2008.

I was expecting alittle more out of the R33 GTR's...

If I were you I would be putting in a aftermarket Down/Front pipes and a high flow cat and it will free up your exhaust a lot more, especialy for GTR's.

+ Other things can effect a dyno run, like doing an oil change will help, check your spark plugs, clean your air filters and the type of fuel you use... A small things can add up...

    • I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless   
    • Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.
    • You need to know I am sorry for this.  
    • As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1    
    • Nah. H2S. H2S is "rotten egg gas", which is what is associated with no cat. SO2 is equally nasty, and if you've ever smelt it you'll know all about it. More of a choking, acid in the back of the throat sort of thing. But you can only smell it in a narrow range up to about 1ppm. Above that, it irritates your mucous membranes, but you don't smell it.
