Hi folks,

i'v been reading these forums everyday for the last few months and i thought it was abt time that i say howdy :D

me and my 'green machine' (see signature) will be havn our 1 year anniversary and i thought that i'd get her a special present ie

Unichip and a K&N panel filter :badgrin:

Questions

1. can i expect a Ralliart spec power output ~ 180kW at the fly ??

2. 0-100km/h of around 6.5s?

3.what sort of fuel econ? i usually get under 10L/100km for highway and abt 11 - 11.5 L/100km when i'm enjoying myself :p

I think you might just get the 17kw gain you are after, just. My 1st year Ann. is comin up too, 26th April :D If you get it done let us know how it goes 8)

Doubt it. Typical gain from a Unichip is 5-10kW tops. Remember, the Ralliart has more work done to it than just a chip upgrade.

What's the rated kW power of a TJ Sports vs Ralliart in their std forms?

refer to this thread (http://www.aussiemagna.com/forums/viewtopic.php?t=6525&start=20#88173)

OK RATED POWER IS A S FOLLOWS
Ralliart 180 kw 333nm
Sports/vrx 163 317nm
If you fit a UNICHIP and a filter also do extractors the it will have a higher output.
I have done these to my VRX and it is now quicker that a Ralliart.
KW gain is important but the torque gain is more important for every day driving.
The fuel economy is now a bit better than before but of course depends how you drive.
I would say do the mods.
Even if you got 10 kw from the chip and 5 or 6 from the pipes you are even and the torque will be better.
JUST DO IT
you wont regret it

hmmm...

gremlin reported a 14kW gain (163 --> 177) from the install of a Powerchip..
but as i understand it, these chips are not tuned..

i think i read the k&n panel gives abt 3-4kW ??


any thoughts on the 0-100km/h assuming 180kW ?

also is Croydon Motorsports the best place in Sydney to unichip installed?


cheers

Correct, Powerchip's aren't tuned. Did he do a dyno run before and after or was he quoting what their site says?

Whether a panel gives that much of a gain is debatable. That's something I want to investigate at our next dyno day. Thing is, chassis dynos aren't as accurate as desirable. Even a back to back power run within the same 3 minute bracket will return a different result.

revelstone2 you got pacemakers extractors? How much did the chip set you back? Well if you have 180kw and 333nm of torque assuming you have a manual you might do 0-100 in say 6.71 ( ha claimed ralliart times by MMAL :lol: ) Ha sorry, you will probably do 0-100 in 6.6 i would say with those 3 mods.

Ralliart Auto 7.12 sec 0 100kmh
Ralliart Man 6.71 sec 0 100kmh
so I would imagine you are looking just sub 7 in manual
again depending on your driving

i think krish if u dont intend doing anything else atm, u could get close to the gains you want, K& N panel on these meant to give about 4-5 Kw and a unichip maybe 10 Kw esp if u have it tuned for running premium unleaded, powerchip calim 10 Kw for 95ron and 15Kw for 98 ron and a unichip should be able to do the same, those options should in theory take you to around the ralliart output from a sports.

wow does a panel really give that much? :shock:

If you want real figures, just look at Manual's (ex?) car..

muffler, over-size (70mm) TB, extractors, CAI and a greddy E-Manage = 145kW ATW (193hp ATW)..

going by the rough estimate of hp ATW = kW ATF (at the flywheel), that's around 190+kW which is well past Mr Ralliart.. and all that's without cracking the engine open. Throw in a set of Stage 1 or Stage 2 cams and you're looking at something truely evil. :evil:

dont think the guy wants to go that far atm, i got 170 kw at the wheels from a 3.0 and auto without opening the engine.

the panel is meant to give that gain.

oops correction, 170 hp atw, anyway point is that only a dyno of a Sports with a unichip and K&N panel is any use here, not dyno of car with lots of other mods.

lol moody :oops:

You know you guys are gonna force me to modify my Ralliart now with talk like that. :lol:

Turbo turbo :badgrin:

What are your list of mods, Altera98????

I gather you have a 3.0L Auto Altera at 170hp at the wheels (~127kW). What else do you have?

Ralliart, u still win mines bigga than yours... for rear wing. So find a better excuse like blowing off commodores!

white devil my cars got wildcat extractors, 65mm t/b, K&N pod, Greddy ecu, FSE fuel pressure reg, and slick 50 friction treatment. still stock muffler and regular unleaded btw.

Is the 180kw of the Ralliart and 163kw of the VR-X figers at the flywheel and not at the wheels?

Flywheel. That's what manufacturers can quote as they can use engine dynos. Us plebs can only quote wheels results.

All you Ralliart drivers out there, dont be too worried about these modified sports and VRX's just yet.

The 180kw claim seems to be a conservative figure.

I had my car on the dyno last week and it showed an output of 147.7kw on the front wheels.

That is totally stock standard.

To me, that means more than 180kw at the flywheel. Can anybody comment on that ??

Now, if i go and spend some cash on the car to do the same mods as the other Magna boys, im sure there hopes of chopping up a Ralliart will surely not come true.

Either way, im not out to dishearten or race any other Magna drivers, we should all be banding together against the rival models, but, i do get annoyed when a Magna sports boy with a sports exhaust says he can out do a Ralliart.

Bring on the mods to my Ralliart - "Hello, this is powerchip, how can i help you......."

hey dude...
converting kW to HP your dyno figure of 147.7 kW = 198.07 HP at the wheels...
using the old rule of thumb that HP at the wheels is about the same as kW at the flywheel,

soooo your Ralliart has approx 198kW at the fly(ppls, correct me if my calcs are wrong)

Now, i originally made the this post to get an idea of what sort of performance gains i could expect from a unichip and panel filter and the Ralliart was a useful point of comparision!

I wasn't trying to say that I could chop Ralliarts after these simple mods!
Ralliarts are Ralliarts and Sports are Sports...

I just thought it would be wicked to enhance the sleeper image of the Sports even more by upping the performance...

Can you post the dyno sheet on that one? Damn, if you did pull 147kW ATW you have one freaky ralliart. Off course all dynos are different, but still. That's huge. Congrats.

147 kW ATW is huge - almost 200kW (198kW) at the fly..

but there was a post about a week back where a guy was talking to someone from engineering dept of a local car manufacturer and he reckons that the figure that manufacturers quote is at the fly and is the absolute minimum of the 10 engines that they dyno.. the most ideal situation is that the engine in your car is 8-10% better than quoted..

so if we look at this Ralliart ~ 180kW stock + 8% for being lucky + ?% due to the dyno, ambient temps etc etc... 147kW ATW is possible

but i'd hate to deal with the torque steer that the 200kW FWD beast produces!!

I have the dyno sheet here.

And it was no fluke or no freak as there was another Ralliart there as well from the same place as i bought mine from and it put out 145.1kw at the wheels.

Needless to say i bought the one which put out the 147.7kw !!!

I have the Dyno sheet and if i can get my hands on a scanner, ill post it up.

But, if you want to clarify it, the place who dynoed both the Ralliarts was Silverwater Automotive Services (SAS) which is quite a well known tuning shop in Sydney.

Give them a call to question it if there are any queries.

And yes, the torque steer is crazy on my car. It really does detract from a otherwise great car.

Especially in the wet, this thing is dangerous.

Fitting a strut brace tomorrow, lets hope that settles it down a bit.

hey ralliart boy!

congrats on your freek car! :P
but....

yours must be the tip tronic, cos the manuals' have LSD which "should" reduce/stop any torque steer right?

just a bit off topic, i personally, think since adding all those extra poinies at the front treads, im more then confident that my beast steers in a better straight line then when it was stock :neutral: perhaps im putting too much power throught the drive line which advertsly locks both wheels? cos ill post some vids of me at the drags, and you can see this thing will follow a straight line without hesitation.

no idea.

BOoya.

What's all this namby pamby talk I hear of people not being able to handle the torque from a powerful front driver?? The trick is to actually drive it like a front wheel drive car.

And I've never understood this concept of "too much power". There is no such thing!!

where did anyone say they couldnt handle the torque, i was purely trying to point out that my car seems to enjoy the straight line much more now lol

Wasn't actually talking about you BOOYA. Ralliart Boy said he couldn't handle the torque.

LOL. sorry!

i confused you for that other ralliart owner! damn screen names! both had ralliart in it! lol

as you were capt'n :cool:

No worries BOOYA. I'll let you off with a warning this time. (by the way, where have all the emoticons gone?)

Also, on the subject of dynos, how much should I expect to pay to get one done?? (or several)

from my experiences' from using dyno's in the NT and Adelaide, they seem to average round about $70bucks a pop.

a pop would prolly be around 3 "runs" with a dyno print out.

but dont expect any tuning, just expect to find out approx how much your car puts out.

tuning a car is normally around 90 to 120$ an hour! :redface:

thank god i have a sponsor with a dyno! lol

It's not a matter of not being able to handle it, i have had a lot more powerful turbo front wheel drive cars.

It is a matter of enjoying the drive and i dont enjoy it when my car wants to go anywhere except straight. But, i have plans to settle that down.

It is a manual too so maybe the LSD is helping.

Also, the Dyno was paid for by the car-yard who took two Ralliarts down for comparison purposes so im not sure how much it costs.

sounds like a good deal!! (the dealer supplied Dyno!!)

as for dyno's, and they're inconsistancies, it can also depend on what setting they're on, 'shootout' mode is the most common but this can be set up incorrectly as well!! (i've seen it done, on a Gen III which on its first run gave 260rwkw!!! haha, second and correctly set up run yielded 197rwkw, thats more like it!!), they have a correction factor that can be changed... (some sneaker/dodgy operators play with this between tuning!!)

all good though.. good to hear some good figures... and even better to hear 'lesser' magna's coming up to speed!!!

Those polyurethane engine mount bushes that RPW sell (I'm sure any engine place could do it for you?) should help reduce torque steer too, shouldn't they, by reducing how much the whole thing flexes. No idea what the cost is..

on the off chance Mitsiman reads this thread - have you done this to your TT?
