Do you have enough power?

[USC]

Hey Guys,

do you feel like you have enough power in your AH sri-t?? I think I am too used to it as I cant feel the difference between driving this and a normal aspirated car anymore!!

also, do u have a rubber block in the front suspensions? I noticed that the other day???

[MatsHolden]

Sounds like you've still got the blocks in for transportation that should've been removed on the pre-delivery check.

[oneightoo]

i never felt there was a HUGE difference in the astra turbo from my calibra.. theres a nsw member who'se turbo was only a nose ahead of my cali at a streetlight grand prix..

[Tfer]

Don't know about the AH Astra SRi-T but I know my Veccy has long enough legs, and is deceptively quick :)

Do I feel as though it has enough power? No. With just the normal mode on (not Sport) it does feel more naturally aspirated. Having not owned a turbo car before, it has taken a little getting used to. Even this morning, I was like come on come on, cuz I took a slower corner in third (instead of second) so had to wait for it to come on boost. Sport is better, with more noticeable shove. I also had the dealership i purchased the car from kindly leave a rubber transport block in the front suspension. Ended up taking it to a dealership I didn't like for them to help me get it out. Called first to see if they could help me out, as it was midday on a Saturday. The new car manager said sure, bring it down we'll sort it out. Get it down their and the absolute %@*&heads couldn't help me out at all. So i got all the jack and that out in the carpark of the holden dealer, jacked it all the way up and yanked it out myself.

[RudeOne]

Does the sri have a sports button like the vxr that shortness the accelerator travel? that always makes for an interesting drive ;)

[USC]

well if u like USC i'll take ur sri-t and u can have the cally :)
:D :D

she`s still sweet though ;)

oh regarding the rubber blocks, they are in the springs!!! on both sides of the front suspension! i tried removing them but they are really tight!! very hard to remove....hm...can anyone check their sri-t please? i dont wana wreck anything...

bloody hell, if they were supposed to be removed prior to delivery, Im gona be so pissed off with Holden...they REALLY SUCK!

[USC]

yeh, I drive with the sports mode on ALL the time:D ..with it off, the car is very sluggish....hahaha

dman it! shouldnt they have removed the rubber blocks?? there was a sticker in the glove box when i bought it saying to remove them which I thought the dealer had done!

are they at the top of the springs and have big teeth that just go in between the springs? just wana make sure we are talking about the same thing.
i might get them to remove them at my next service if they dont come out.

apparently, they did a mechanical check prior to delivery...idiots....

Yeah it's a black rubber block, maybe 12cms long by about 3cms wide from memory and it sits very snuggly in the spring. If it was me, I wouldn't be driving around with it in. If you are able to jack it up yourself with the kit in the boot, you'll be able to pull it out. Pain i know, but at least it's out.

I havn't driven, so can't comment on the AH Sri t but sounds like they're slugs compared to the TS Sri t.....even alot of mag reviews have said the same.

I have test driven the VXR and wasn't impressed, so maybe the lower power Sri t does need more guts :rolleyes:

As far as rubber blocks been left in there, that's disgraceful !! More shame to GMH......

How long have you been driving with them, hopefully no damage has been done, you must have noticed, the ride wasn't normal at all or car sitting a bit high ???

It's a dealer thing mate, it's their responsibility to remove them. And yes they definately have to be removed.

[blueraven]

Hey Guys,

do you feel like you have enough power in your sri-t??

Yes.




(the stock car has very smooth and early boost, which makes them feel slower than they really are.)

[USC]

yeh, GMH is disgraceful...they should train their stealers to prepare the car properly. Ive been driving with those blocks since new!!! No wonder I couldnt notice any difference in stiffness of suspension when sports mode is on.

Most people wont know about those blocks...unless they are quite technical...

I m gona try remove them myself...im so lazy..cant be bothered getting the jack out...haha...

definitely wont be getting a holden again.

re: power ..i think the car still feels a bit heavy..:D...need a B4 engine in there...

[bornwild]

Nah, step on it in 4th and see how it gets from 80 to 120.....quick ey

[oneightoo]

even quicker in 3rd..

[bornwild]

even quicker in 3rd..

4th is an internationally recognised standard :p:p

[cbrmale]

I can't comment on the SRi-turbo as I haven't driven one, but I have driven other turbo cars and they generally have a sluggish feel at lower engine revs, with the extra performance becoming noticeable once you wind it up. Turbos have lower compression ratios than normally aspirated engines, so off-boost performance can be quite average.

My own car is a SRi 2.2, which is an interesting combination. The 2.2 is very smooth and very torquey with a sharp top-end if you want to go there. There is no doubt that you have a more powerful engine than a 1.8 under the bonnet. And push the sport button at your peril, 'cause the extra throttle response on top of all that torque can be awkward to manage.

As for the transportation blocks, I am sure that GMH have documented pre-delivery procedures for all Astra models. GMH cannot be held accountable if certain dealerships don't following procedure. Just make sure that the issue is raised with GMH, the new car survey forms are one way to do this.

[blueraven]

with an sri-t you need to stay between 2.5 -5.5k to keep it in optimum power/torque...

[Wraith]

Agree.

If she's stock, torque starts to drop off sharply after 4,500rpm, even with an agressive map, she'll happily rev to 6000rpm, but there's no point as the torque curve is way gone by then.

I've found on mine best and quickest performance is had in the 2500rpm bracket from 2,500 - 5,000rpm, I change all gears at max. 5,000rpm (even 4,500rpm produces good results) and it seems to be the quickest result.

On a heavily modified engine, the optimum rpm band will move up.

[blueraven]

80-120 in 4th - just under 5 seconds...

80-120 in 3rd - under 4 seconds...

100-180 in top gear - 10 seconds...


Got midrange? :D

[xplosv57]

This thread has been very helpful, was considering an AH SRi-T but if they're sluggish and slow, may have to look elsewhere...

And with regards to the suspension block, should've been taken out at pre delivery, but best thing to do is, take it out yourself then throw it at them at your next visit, those blocks are fun to throw around!!

Don't have an AH SRi-T but I think we all feel the same at some point - hence why we all start MODIFYING!

[SIMid]

Might feel sluggish when you get use to it, but I went for a cruise with a Golf GTi, 3 MPS and Civic Type R on the weekend and all I can say was the SRiT kept up with them, especially with the Golf and TypeR. MPS was a bit difficult along the straights.

But still, wouldnt mind a remap when the time comes! :p

Agreed, am organising a drive soon of an AH, have driven a few modded TS SRi-T's before....

LOL well the B4 had nothing against a certain boat anchor commodore over the weekend, corners it would been better, but nothing in a straight line!!!

[dieselhead]

nah, the diesel is slower than a VXR for sure. anything else, I mean AH Astras, bring'em on! :)
not talking here about cars with $15,000 worth of mods on. if you limit your modding budget to say $1,000, I can't see a petrol turbo being able to compete with the CDTi.
the SRi T is not too bad off the line, but when you start rolling at speeds over 80 km/h in the diesel faster. you guys should see how an 140-ish kW oiler accelerates in 4th or 5th with "sport" button on!

do I have enough power you may ask? well, I thought it's not too bad until I read about this bloody Alfa 147 JTD (pretty much same engine as mine) making over 180 kW and close to 500 Nm... now that would be just enough for an Astra IMHO

[USC]

Actually the 888 Astra CDTi is little more than a brake/suspension + wheel package + ecu remap and it keeps up with the VXR...evidence that the engine has what it takes.

pfft - crap excuse

As for the AH SRiT - was lucky enough to punt one around the track when Vic members went to DECA earlier in the year, and was pretty surprised with what it felt like even with "only" 147kW. You just get used to the power that's all.... First time I launched the Rex I got a headspin, now its like meh - same old same old..

[digifish]

... First time I launched the Rex I got a headspin, now its like meh - same old same old..

You will get used to anything.

I always note that my CDTi will pull in 3rd from 60-100, on the transition to an 80, zone quicker than my brain can react to the fact that I am 20 over the limit ... at the end of the day any moderatly quick car is almost impossible to enjoy legally around town.

true..but if you do all that to an SriT, it would probably leave the diesel miles behind. Top speed in a petrol is always better than a diesel as it can have higher revs.

I agree diesels are pretty cool and I love the huge torque...

ps: the sriT can pull from 60-100 in 6th gear pretty quickly.

Hang on...the VXR/OPC/HSV Astra *is* an SRi with 'all that' done - bigger turbo, remap etc....

The 888 is just a remap in the engine department.

cant see the same mods going onto a CDTi with the same results.

YOu have no idea how wrong you are :) I agree that stock vs stock the cdti is the faster car on the road in a straight line, wont comment about handling, but i have seen how quick martins cdti is, and the gap between my cars performance and his stock car on the freeway is not as big as i had thought. i mean hell, all it takes for him to get 400nm of torque is a greenbox, look at all the shit i have done and 422nm.

400nm would also tear his gear box quicker...

you wanna know why the diesel is cheaper? 16" alloys, no leather and no climate control. and lesser stereo i think. all things equal i doubt the diesel would fetch less than a SRi Turbo.

[Shaun]

USC its like anything. After awhile you become used to it and it feels slow. when you modd it it will feel quick for a while then you will be come used to it again and be thinking the same thing.

$400 for re-flash? where can you get that?

The Ecu re-flash can be done on a CDTi, too. Let's just leave it out for this exercise...
After re-flash done or Green Box is installed you get about 30% more power and 25% more torque. If you want the engine to run smoother, get a Simota Carbon induction kit in for another $220, or a K&N panel filter for $100. That's all you need to do! Isn't that cheaper than modding a petrol turbo?

Can I ask, what is the power/torque output of a re-flashed SRi Turbo with few other mods within $1,000? Real figures on dyno, not legends, please...

[digifish]

if the cdti was a faster car...it would sell for more than the sriT....

I don't think so...there is a big mental hump to get over for most people to switch to diesel....and for good reason, it's a very different driving experience to that which the average boy-racer is expecting...

digifish

[Wraith]

if the cdti was a faster car...it would sell for more than the sriT....

Without taking into account the good or bad of turbo diesel vs turbo petrol, I think you'll find that the main reason why the Sri t outsells the CDTi is because of the car configuration - ie: 5 door vs 3 door !

I'm pretty certain in saying that if we had a CDTi 3 door AH, the turbo diesel sales would be on par or exceed the Sri t sales ;)

Now that's more like it......

Like I've said before, if you could get a decent car in the current hatch size market with a diesel making at least those figures above (200kw+ would be better and I'm sure they'll eventually get there) then I'm a convert and would consider an oiler :)

Only thing then, would be to find a fix for that awful black cloud that would be constantly following you around....

According to him, 335i is a bit quicker off the mark but the 335d is way quicker from 80-120. :) It's about 50000Euros over there. However, the 335i has one advantage over the 335d....it's available in X-drive :D

Is that Wright??


Car has down pipe, intake, iridium plugs and flash tune only. Running at 15-16 pound peak boost the AH's (Steve's and mine) produced in-between 142 and 148 KW at the wheels.


I have run the car down the quarter mile in the mid 14’s so I have no doubt these figures are accurate. The Dyno was done by Torque Performance who are thought to be New Zealand’s top tuners.


Many stock cars were tested that day and power figures equated to factory claims, so I dunno maybe my cars a freak

agree with him /\/\/\

both at the same dyno day and mine made 148kw at the wheels , same intake , tune, etc

now with the sports button on its a handfull , if i can take a photo of the dyno sheet i will post it later

Just as a side note took the new WRX for a test drive and thats ment to have 168kw at the fly , granted the engine was new etc but that felt slow in comparison .

from what I read, the VXR has just a few internals strengthened, that's all. that's why I wonder how much more can you squeeze out of that engine.
anyone that could throw a link of two for us to find out how high VXRs can go?

Stock standard they can go a very long way......

Components wise, it is a much stronger engine than that of the Sri t.

The turbo (K04) will flow to around 230kw and 460nm !

With further tuning, (cams, turbo) but still same internals they can go to over 250kw...

Regals do a high torque tune, which can generate over 500nm !

Check out the U.K. tuners Courteney Sport and Regals for all the info...

Or German tuners EDS etc....

bet you i can squeeze a shit load out of it! my 1.8l is in the zone of 420 fly wheel horse power

and blow it in a couple of weeks....:naughty: :p

[blueraven]

impossible... there is no way in the world that the K03/04 (assuming its same turbo as on Z20LET) will flow that much power


Yes. Impossible.

i am using a stock vxr turbo(K04 variant..of which there are heaps) which is identical to the sri-t turbo aside from having a better cast manifold, and have 200kw~ at the wheels.

So obviously its impossible. Especially considering there is more than half a dozen guys in the UK running similar power (all quoting circa 300hp at the fly) with the same turbo, i think some even still have the std sr-t turbo. Again...impossible!

and the difference between a LEH and LER is: forged pistons, compression ratio, crankshaft and under pistion oil sprays for cooling....and a few other things i think.

[blueraven]

and blow it in a couple of weeks....:naughty: :p

not true. he has had that kind of power for quite a while now...

[dieselhead]

how on earth would you manage 250 kW through the front wheels of an Astra Coupe? :confused:

[Wraith]

OK then, start saving for the BMW 335d, 3.0 litre 6 cylinder twin-turbo 210 kW and 580 Nm torque from 1,750 rpm. I don't need to say it corners too. Will accelerate to 100 km/h in about 6 seconds... Despite its performance, it still does 37 mpg (combined cycle).
There you go.

That sounds good, but would depend on it's cost, compared with the 335i and when you look at the figures of the petrol turbo, I'm still not impressed with the oiler !

You can now get flash tunes (Xede) for the 335i that put it to 300kw and 500nm, stock standard the petrol turbo develops 100% of it's torque (ie: 400nm) at just 1,600rpm !

The stock 335i is in the 5sec zone 0-100km/h in fact it's quicker than the E46 M3 ! imagine the flashed examples performance.

The only reason I'd buy the oiler is for long range/economy....and would still have to get rid of that annoying black cloud following me around :D

[Wraith]

how on earth would you manage 250 kW through the front wheels of an Astra Coupe? :confused:

The original question was how much/what's possible - these numbers ARE possible with petrol turbos !

Managing it is another story and I agree, those numbers are definitely too much to manage for FWD but LSD and smart electronics can help - such as the MPS 3.

[dieselhead]

yeah, we all know how well that works on the 3 MPS...

about the 335d: I agree, it ain't cheap, but what it is telling us is that other manufacturers will follow suite. I heard some rumors about GMs next version of 1.9 CDTi, should reach 150 kW stock easily. Recently, GM bought big into VM Motori, the Italian mob responsible for developing the oilers used by Opel and Alfa. How much a twin-turbo V6 would put out you reckon? 200 kW should be within their reach, surely. just imagine a HSV wagon with that engine on!

[Wraith]

All the info on future diesels sounds good, but until then I won't convert :)

As for MPS 3's LSD and power curtailing in 1st and 2nd, it works just fine - I've driven one - have you ?? I'd bet you'd love it and prefer it to your oiler (green box or not) for spirited driving ;)

I'm sure Dug has explained it here all before too :)

[USC]

420 KW at the fly wheel!! thats crazy! thats about 350 kw at the wheels right?

[Apex]

Not sure of the conversion, different cars loose more than others.

Funny, my Corolla is more a handful with 90kw than my Astra is with nearly double that. I wonder what the ideal limit for an Astra would be. 200kw @ the wheels??

[blueraven]

With an uprated clutch and an ATB Quaife DIfferential :) (lsd).

Yes, it can be a handful.

He said HP not KW. And yes he is a crazy Mofo, but his car is definatly a labour of love and quite possibly the most rapid barina/corsa on the planet.

I wont be chasing any more power, the car is brilliant in anything other than first gear, more power would only mean faster highway acceleration, and trust me, i have enough.


(rolling at 100 in top gear i still pull away quite quickly compared to the cdti in 3rd :) and as i have said before, the cdti woul dbe every bit as quick as an ah sri-t.

I disagree, we (my fiancé driving) left a customer of mine’s Astra diesel for dead when our car was stock. Maybe they just feel quick :confused:

Your customer don't know how to drive. :cool:

[dieselhead]

well, fact is the stock SRi T is about 0.5 seconds faster to 100 km/h than the CDTi. Left for dead? I wouldn't think is that dramatic, really :)
I left behind a Range Rover V8 Supercharged (291 kW) yesterday. We took off at the lights, the 4wd charged a few metres ahead of me until I changed into 3rd, when my oiler really took off. You should have seen the guy's face! Am I proud? Of course not, that's a stupid 3 tonne monster... No match for my light diesel, despite costing 6 times as much :) Now who said here cars are faster the more they cost, or something like that?

[Apex]

Im just telling it as I saw it :p
FFS you diesel drivers have the car equivalent of short mans syndrome.
Everyone agrees the diesel goes ok :boohoo:

[bornwild]

BTW how did you get the little apostrophe to show above the 'e' when you wrote your fiance??

[xplosv57]

I'm sure my car can beat cars worth 10x as much, but if i had the money, i'd rather have the more expensive car cos it's most likely better made, get more looks and more so would have better resale value!!!

...just like like you petrol heads! why all these expensive mods and ECU re-flashes? that's because we never have enough power!
the only difference between us diesel drivers and the rest of the world is that we love Nm more than we love kW. Oh, and we keep an eye on that fuel gage, only because we care about our poor planet :D

[USC]

I wonder how would diesel engines go if they created diesel spark plugs..hehe...it might reduce the noise as the diesel wont rely on just compression to burn anymore..

[dieselhead]

you're talking about the Diesotto engines from Daimler, are you? there is such thing being tested as we speak, that works as a diesel in the lower range but switches to Otto cycle at higher revs. so you get Diesel torque, economy AND petrol like power.

"This 1.8 liter DOHC inline-4 engine with variable valve control can produce 238 horsepower (177 kw) and 400Nm of torque, but consumes less than 6 liters of fuel per 100km - not on a small car but in the current Mercedes Benz S-Class!"

[USC]

Actually, I was talking about making diesel engines burn diesel like a petrol engine, ie, using spark plugs--which will lead to less smoke and noise. I see daimler is doing the opposite with petrol engines to try get more torque..thats very clever!:D I love technology!

[bornwild]

Daimler is actually using Diesel fuel...in a petrol-like engine...

[USC]

dude, its a gasoline engine that combines the advantages of both conventional petrol and diesel engine, ie, it will burn petrol without spark plugs at low revvs for more torque. It does NOT use diesel fuel. It uses petrol but has the characteristics of a diesel.

[bornwild]

Really? I remember when it was just announced on worldcarfans they said it was diesel....bugger that's not bad ey using petrol hmm

[coyotte]

Prior to my 04 SRi turbo, I had a 2.2 litre SRi. The power difference is VERY noticable, (even if you do have the 2.2lit. "sports mode" on).
An extra 30 plus kws (depending on mods) does put you back in your seat when you plant it).

I take it your 2.2 SRi is the old model, not the current AH model? The direct injection 2.2 has more low-down torque than the previous incarnation of the engine, although it is not a particularly sporty engine. Hotter than a 1.8 and very good with an automatic, but not meant to be a competitor with the turbo.

Indeed, I suspect the current 2.2 Astra models (which are exclusive to Australia) evolved out of the need for a hotter automatic.

[Kippa-Dee]

bah. all this bitching about power. I'll trade my Barina for one of your Turbo's anyday, THEN let me hear complain about lack of power.

hate to brake it to ya but theres not much difference between a 2.2 to a 1.8ltr:cool:

but a massive difference for both to the turbo, even if the turbo is stock

[Vectracious]

Have to agree with Gav - on many a cruise I've been on, there has not been much between (and I'm talking Astra G here) a N/A SRi and a 1.8.

[bornwild]

well the extra 400ccm are only good for a bit of extra 'smoothness'

[luvpsi]

the turbo's extra torque and linear power delivery play a major role here:D

[cbrmale]

Have to agree with Gav - on many a cruise I've been on, there has not been much between (and I'm talking Astra G here) a N/A SRi and a 1.8.

Well, the current 2.2 is significantly different to the older version of the engine: the direct high-pressure (120bar) fuel injection allows a 12:1 compression ratio for a start. 120bar is about 1,700psi.

The AH 2.2 will do 0-100 in the mid eights, which is not particularly sporty but still hotter than a 1.8. The 2.2's big thing is torque, and lots of it. The new 2.2 puts out more torque (180nm) at 1,500 rpm than the 1.8 does at its torque peak of 3,800! This is why the 2.2 works so well with an automatic.

And the torque keeps on building from there, which makes the 2.2 great for flattening hills and for overtaking multiple cars and trucks (which is what I wanted). And it goes without saying that the 2.2 is good around town too.

The shove in the seat or extra power feel between the 2.2 and a turbo would be more from the substantial torque difference than the power difference ;)

A very close friend of mine has a TS 1.8ltr sedan, compared to a another friends 2.2ltr hatch, there is a very noticeable difference in power and go...however both feel like total weaklings compared to my heavier turbo convertible, even when it was stock....both those guys freak out when they ride in my vert, at how much stronger it feels and pulls and my vert would be slower than a turbo hatch because it weighs alot more :)

[oneightoo]

i've had both the 1.8 and 2.2..

gotta say the 1.8 picks up in low revs a lot quicker, but overall the difference between the two is very noticeable.. the 2.2 is a better drive..

haha..I agree...2.2L will pull a lot better, especially if you have 2 or 3 passengers in the car...you will notice the difference a lot more then...
