would anyone know the stock australian spec of a 2000 itr

i tried search but they are all the US versions with roughly the 155hp to 160hp

which seems fairly high for aus spec

if 160hp at the wheel then it's 120 kw at the wheel hp-kw = (hp/4)x3 = correct?????

that's awfully high isn't? considering the stock aus spec wrx is 98kw at the wheel

can some one please enlighten me?

thx again

 

One thing I'll say is that stock WRXs dyno lower due to the AWD driveline losses.

 

The 227hp WRX and the 195hp Rs here lay down about the same on the dyno IIRC.

 

yeah i forgot about the 4 wheel drive thing there!

but could anyone please give me some numbers in KW for the aus spec itr please?

 

141 KW @ the crank.. hmm Google says that's 189bhp.

http://autoweb.drive.com.au/cm....html

If the average baseline dyno for a USDM ITR @ 195bhp on a DynoJet is say 160 whp...

the AUSDM ITR in the same conditions on the same dyno would be around 155whp or 115.58 KW


that's not scientific in the least and I'm kind of surprised the Aussie R doesn't make as much power as the USDM. Doesn't it have 11.1:1 comp pistons? Which tells me you guys have a good fuel to allow that.. hmm.

yeah thx, buti know the 141kw but i need numbers at the wheel please!

anyone else?

it can vary, depending on ambient temp, how the dyno is calibrated, what you had for lunch.. j/k

anyway I added more to my post above.

 

I'm beginning to wonder if the Aussie R's power rating was a little underrated.

 

thx alot for the info

im using 98 octane and i got a mugen intake, and mugen catback exhaust tuned with vafc2 on a 32 deg C day and i only got 108kw... what's with that?

problem is i didn't have a before graph...

It would def be good to have a baseline graph from the same dyno, on a similar temp day. What kind of dyno was used?

89.6 degrees Fahrenheit, that's a little warm. Was it a humid day? Did the engine have time to cool down before the dyno pull? I'd ask about fans blowing on the engine bay but I don't know if that really helps too much.

 

i really appriciate your help! but the place i took it to, they had to drive the car to another shop around the corner because they don't have their own dyno, so i wouldn
t have a clue to see what was done... but those numbers do seem low...

however so the car seems alot smoother... so either i gain some mid range or i lost so top end... i dunno sort of hard to feel...

they seem to be a very acknowledge tuning place, they used to have there own dyno but the business split and he started again.

but friends dc5 aus spec did 114kw at the wheel ith I/H/E and spoon throttle body, which i think doesn't do anything...

anyhow thx alot for the infomation

 

No problem at all! I wish I could be more helpful. It's been a long time since I had a car dynoed. My R dynoed at 155whp stock on a cool morning when it wasn't really warmed up fully (my mechanic just had me throw it on the dyno at a dyno day between paying customers' runs).

The most important things are how the car accelerates and when it comes to the dyno graph, the area under the power curve. A nice flat torque curve is good, as well as a smooth power curve.

You might want to try an Archived search with your mods as the key words to see if you can find power increase information from other users.

 

yeah, they guy did a very good job in regards to a very flat torque plot and very smooth power curve and don't get me wrong i really like how's he has tuned it!

only thing is you don't get that surge of vtec pull anymore this is due to the smooth graph, which is better and safer for cornering, no more vtec jerking when coming out of corners

just that numbers seem low that's all...

thx alot!

 

108kw isn't too shabby at all

What type of Dyno? Theres just so many variables though. Did you do a run before you started modding?

 

Your numbers are about spot on; on a Dyno Dynamics Dyno in Shootout Mode in Aus a stock DC2R pulls between 90-93kw atw. But Freakygeek is right there are too many variables, don't worry about the actual numbers just try and look at the gains made from your mods (if you have a baseline run).

 

Here is a simple thing... Most ITRs have a 16% drivetrain loss. I had 16% if the caR actually has 195 at the crank.

 

thx alot for the input guys! yeah i found out it was on a dynamic dyno, at 100 ramp

i talked to the the tuner and he was not concerned with numbers at all, he said the most important thing was to make sure the power curve was as smooth as possible as well about flat torque plot, he said making sure the vtec engagement was in the right position was another important factor, and that what they were the most impoartant things. what ever number comes out then so be it he said. but also he mention that on a colder day would have had slightly higher numbers. he said if i was corncened with numbers he could easily adjusted to anywhere between 10-15kw etc but then i lose the smooth graph, there are just too many varibles with dyno, place weather etc...

but i never knew the aus spec and us spec had such a difference in power!

anyhow thx alot for all your input

 

how do you post images?
like to share my graph with you guys

 

just worked it out

http://www.we-todd-did-racing....D.jpg

 

but it's just a link how do you place the image onto honda tech itself?

 

like this:

(img)http://www.we-todd-did-racing.com/wetoddimage.wtdr/wODgzNjQzNnM0MTNkZmQzMXk1NDE%3D.jpg(/img)


replace the ( ) with [ ]



looks good

 

thx alot for the heads up

now i can post images up to share

 

Looks like you have a very nice power band to enjoy

 

sorry im still new to this, when you mean power band do you mean smooth power curve as well as a flat torque plot?

even thought it doesn't feel so fast because of the smoothness(not as great vtec surge)
i still love it

but feel more confident around corners, i was worried about during apex that with an unsmooth graph, if i were borderlining vtec it would be fairly unstable...

but now cause it's smooth no little suprises coming from the power band.

like to thx craig from Gensis racing in blackburn victoria great job!
