Stock RWKW?

[Mr Hardware]

So this is a bit of a silly thread
but i'm keen to know about what is the usual stock rear wheel kw's of the STANDARD AU motors.
IE i know that the AU non-VCT I6 is about the 110kw mark or so
there's probably the usual 5-10% variance depending on just about everything
So what are the stock rwkw figures, roughly for the:
HP I6?
EGAS I6?
VCT I6?
175kw V8?
185kw V8?
200kw V8?
220kw V8?

i don't really want to know about modified cars. ie if it's more than exhaust and cai i don't want to know about it. the more stock/factory the better.
thanks!

175kw-115rwkw
185kw-125rwkw
200kw-140rwkw
220kw-160rwkw

I think its somthing like that.... But don't hold me to it, im not an expert....

[mrghia]

i'v been told that kw at the motor is about the hp at the wheels?

[The Monty]

I think its about that. HP's hafe generally been around the 125-135kw mark. Wicked engines.

Yep, for an auto, it's usually pretty close to that. For manuals, HP figures are a little higher. You multiply kw by 0.746 to get HP (or 3/4 as an estimate).

So, in theory:
175kw = 130 kw at the wheels (175 hp)
200kw = 150kw at the wheels (200 hp)
157kw = 118kw at the wheels (157hp)
etc.

sweet i got told something that wasn't bulldust.

really? are you sure 118rwkw for an I6? brendan mock told me they were about 96rwkw stock lol
not saying youre wrong but im pretty interested

[HLC]

i had my AU put on a dyno the day after i had a 2.5" exhaust put on. and it pulled 117rwkw.

which equates to 157hp at the wheels lol. i then saw a stock AU on the same day pull around 110rwkw.

As a guide - yes.

i think JMM are conservative a bout their figures because they lump e series and au into the same category of power figures and aus generally make more with the same mods
also if they do some work on a car and it doesnt come out very well the promised dyno figure might still be achievable with their very happy dyno. also if the car comes out fine and achieves more than promised the customer will think "oh my god, you guys are the best!" because theyve gotten something they didnt expect
you will notice most places dont promise exact kw figures because its a legal risk of false advertising so for jim mock to say you start off at 96rwkw and with our such and such package you will get to whatever, a 20rwkw difference might be much smaller than that
check out the dev1 package...

this promised 116rwkw, which i personally would be disappointed with if i had aforementioned mods

[5L]

lol JMM conservative in there figures.

personally i think there figures are abit happy



back on the topic on figures it depends on autos and manuals

an auto will suck alot of power out, compared to a manual.

my 220 did 175rwkw stock, and about 170rwkw is about right for a manual.

the auto 220's get about 160rwkw

[Mr Hardware]

Thankyou to all who contributed with factual information, i'm wiser for it now.

also two comments here
foolish is the man who ever doubts JC - he's like an AU god
and it seems stattic just makes things up as he goes along

dont know what i did to you to begin with but youve been making rude jabs at me ever since i put up my thread in the au build section
im not gonna sit here and talk crap but if JC says 118rwkw is a good indication of a stock figure how is 116rwkw with the Dev 1 kit not conservative?
not saying he is wrong but please explain that one to me someone

[au11futura]

here you go guys just an example for the stats, this is on my car but you can check your own on the link i have provided.

http://www.redbook.com.au/used-cars/...eNum_Int32%7c0

[au11futura]

just go to the left hand side were it sais badge type click on whatever car you have then go to the more details button. It shows kw@rpm fuel econ, and all sorts.

[Stattic]

theyre just flywheel figures, were talking at the wheels

[au11futura]

what dont tell you can't work out at the wheel figures from flywheel?

it's a good site for people to check out general stats mate dont critasize people trying to help others.

End of conversation thanks.

[Stattic]

lol are you kidding? i did not criticise you in any way, i was stating the conversation is about rwkw
the flywheel figures have already been neatly posted and are pretty common knowledge and the idea of the thread was to work out the stock rwkw from the flywheel figure so make that a criticism for every other person in this thread including the original poster who asked
also i would assume another reason the thread was posted could be that people could show their stock dyno figures in case people did a before/after on a stock car before modding etc
yeh thanks for your link i know youre trying to help, as was i before i was shot down, i meant no offence i was simply stating its not really the proof the thread is looking for

[au11futura]

sorry mate ohh well i tryed. well that makes two of us who have been shot down haha but hey what do you do?

From what i have heard and understand about JMM is that there figures are never and thats why there called MockWatts : Going on that package you have posted up there i would be disappointed to my EB runs 115.7 with a sports exhaust from the cat back.
As for my AU XR 8 on G&D dyno i got 156 as a stock car, Dyno figures will always differ from dyno to dyno and day to day.

[Stattic]

lol not much mate i think we leave this one be, no sense arguing, nothing to gain talking to people who are here to assert authority rather than discuss normal people

lol well there we go
not just talking jim mock but any au with headers, cat, 2.5 system tuned etc would be pretty poor making 115 lol
but yeh as i said probably let this thread go lol

Yep, granted the calc of 118 seems high, but it is 75% of the quoted flywheel figure (do the maths, and you'll see it's right).

So what does this mean? It means that taking 75% of flywheel to get rear wheel power is ONLY A GUIDE. What does that mean? It means if you get either side of that figure at, say +/-5 or 10%, then that would be about right. For example, the last AU I6 I had dynoed stock was my VCT at 121rwkw. For a rating of 172kw at the fly, 121 is in the ball park (75% of 172 is 129). Oh and my wagon was 110 at the wheels (for a rated engine output of 157 - again, close enough). Then again, my AU2 V8 (rated at 175 stock) was 132rwkw, which is about spot on 75%.

Funny thing is, as the flywheel KW increase, the 75% figure gets better and better in terms of accuracy (75% of 220 is 165, and someone has already said they got 170 in auto form - close enough in my books).

So the 75% thing is a guide only, and will vary from dyno to dyno, and day to day (better in cooler weather compared to a hot day, etc), but it is a good rule of thumb.

[Stattic]

yes i agree it is only a guide
also the other variable people havent mentioned so far is that an engine is 157kw from the factory, you dont expect a 10 year old engine to be making the exact same power over time especially if its been thrashed a bit or poorly/not serviced

Listen here, newbie. I call it how i see it. I asked SPECIFICALLY for rough, ballpark figures for rwkw. You then come and take a dump in MY thread about all sorts issues that i specifically didn't want discussed, like variations and modifications and different dynos etc. I've been around long enough to know all of that. Everyone else in this thread was able to respond to what I asked for, you were not, that's why i had a go at you. Cop it on the chin mate, you were out of line. Pull your head in and people might stop having a go at you.
End of discussion. Back on topic.

JC, i'm interested in what you say about the 75% figure. So are you saying that say, the lower the power the more ambiguous the rear wheel figure?

[RG]

Guys enough.

As for the facts;

• JC is an Oracle of sorts.
• Mockawatts exist.
• Rwkw figures are just a guide, different dyno + different day + same car = different figure.
• I care not for length of membership, threads belong to no one
• People need to learn respect.
• People need to calm down
• Some need to read before they post, outlandish statements we know are untrue will anger some.

That is all.

[MrXr6Tickford]

Everyone had better calm down ok. Stop this kiddy talk, we are all grown up's here.


Damn it, just beat me Russ hahaha

[Mr Hardware]

's cap'n.

[blueoval]

Using JC's method of reasoning, I have calculated my power output AS A GUIDE.

Im currently getting 175rwkw. Approximately 235rwhp. Does that mean that I have approximately 235kw at the engine? I have an auto btw.

[mrghia]

yeah give or take a little bit.
