New to SAAB,

Any Advice on improvements or maintenance?

It is an automatic, metallic green :roll:

There's an element of self help required here... read the rest of the posts!! And try being polite- it will get you a lot further!! :roll:

93, sometimes posts get overlooked, especially on a day where the board is a bit busy. Then they drop out of sight pretty quickly. Sit down, gather yourself and issue a polite reminder to bring your post back to people's attention.

Your query is fairly general, so it will help if we prioritise things. My number one priority would be to ensure that the car is in excellent repair before improving it (by "improve", do you have performance improvements in mind?)

If you have a service history for the car, see what hasn't been done, according to the Saab service schedule, and do it now. I recently did this on a CSE auto. In fact, I did all the items that appear at any service, regardless of the fact that it had reportedly just had an oil and filter change, new plugs, etc. See http://www.quasimotors.com for a service schedule if your car didn't come with one. Also see http://www.saab9000.com where I have documented many procedures along with photographs.

Pay particular attention to the coolant, spark plugs, oil and filter (it goes without saying) and especially the transmission fluid and filter. The auto gearbox on the 200hp engine is only just up to the job and careful maintenance is reported to help extend its life. At 151K miles, it is unlikely (but possible) that it is the original transmission. It is more likely that the original died between 80-120K miles.

You say it is running well and that is good to hear. Don't wait until a problem appears before considering maintenance as Saabs in general and the 9000 in particular don't respond well to this type of reactive maintenance. Once a problem appears it can cost a lot of money and time to fix and too often things go downhill from there, hence the 9000's reputation in some markets for being unreliable, troublesome and extremely expensive to run.

Once you've got that sorted, what sort of improvements had you got in mind? Is there anything you feel is particularly lacking - cornering, acceleration, straight-line traction, load-carrying capacity :!
I'm afraid there is little we can do about the colour without spending a fair wad of dosh on it :) (See my signature to see which colour I have a fetish for :roll:)

Most of all, of course, enjoy owning and driving what I consider to be one of the best cars ever made.

'Fraid not Bill, bearing down in your rear view mirror as ever... :wink:

A very magnanimous reply on your part, I must say...

PS... Off to the dyno lunchtime today for comparisons with/without the water injection running... will try to post results later.

I try to allow people one mistake. If I make a mistake once, then I can claim to be learning. If I make the same mistake again, then feel free to call me stupid.

I'll be interested ho hear your dyno results. I've still to get round to having mine done.

Fair comment...

No dyno yet! :x Got to heffin garage and their dyno PC died. Hard disk failure :evil: (as eventually diagnosd by yours truly after having got in the BIOS tyhen taken the lid offf the damn thing!!)

Still, gave her a quick blast to check fuelling and that's sweet as a nut- the guy commented on how welll she pulls all the way to red line- that's the big difference I notice post water injection and Abbott intercooler.

Of course you'll be removing these anti-competitive items for the Abbott track day... :o

I'll hold you to that (and I'll bring my spanners) :!
I assume you're not far from me. Which dyno do you use?
With all that pull to the red line, what's your intake arrangement?

Guest

Like I said, you'll have to catch me first!!

I'm Leighton Buzzard based. I've used several dynos. For convenience, yesterday I tried to use the one 3 minutes doiwn the road from work in Chalfont St Peter. Not exactly the most celubrious or modern of establishments but they're close and cheap.

Other's I've used include Power Engnieering in Uxbridge- v good, do a lot of Scooby/Evo tuning, guys really know their stuff although not that familiar with Saabs (not many are tho'). A bit closer to home I've also used Autocraft in Houghton Regis. Gavin there is very on the ball and knows his stuff.

If you want contact details, let me know.

By ringing around loads of places I've managed to find one with a slot in Great Granstead(!) this morning (but the guy did say he had problems with FWD wheelspin :suprised; ). Maybe later there will be some plots...

Oops! Forgot about intake...

It's standard apart from using an ITG foam filter. Except that the Abbott intercooler is there as well of course, and given that it flows a lot more air than the standard, I think that's the major factor in keeping the resistance down. No, actually I don't think I know because I instantly notice the difference above 4000 once it was in (and the turbo overboosting!)

The fact that there's not many induction kits around suggests to me that the standard 9000 intake is pretty satisfactory. I think Speedparts do one tho, but there's no figures for any improved power etc.

I might have a word with Abbott (Giles recommends the ported head next!!)

Abbott reckon that air induction cuts torque on a 9000 - I have an ITG Maxogen on the Elise (supposed to add up to 9% power & torque too), but Giles said to steer well clear.

Do Saab tuners bother to port heads and change cams/verniers as it seems like a common and effective route to more power in an Elise/Caterham?

Oops, missed the last comment! Check prices of porting specialists before you go to Abbott - look at the Elise archives at http://www.british-cars.co.uk/cgi-bin/gen5?runprog=lotusbbs&access=41758556806021&mode=a rchivesubject&subject=2050. Tonnes of stuff there. Dave Andrews seems to be one of the expert head porters - his e-mail add is DVAndrews@aol.com.

Well I got there no probs (SatNav is a wonderful thing...)

But sadly he didn't have a plotting type road, so we were only able to do some static measurements...

I guessed peak power would be at circa 5500, so we measured in 500 increments up from 3500.

Results? 225hp/242lbft- AT THE WHEELS!!!!!!!!!!!!!!!!!!

Allowing for a nominal 25% (varies between 20-30%)transmission loss that's circa:

300hp and 322lbft at the flywheel (and I reckon we didn't get to max torque either)

Or taking the limits of transmission losses

280-320hp and 300-345lbft :evil:

Without water injection, power dropped by about 10hp.

Track day here I come...

BillJ

Sounds good, but 25% transmission loss? :o Perhaps on a Scooby, but I'm told it's nearer to 10-15% on the 9000. That would give you about 270hp/290lbft, which sounds more reasonable.

I suppose Abbott would know the transmission loss. Then again, I think all their dynoing is done on an engine dyno rather than a rolling road.

Where was the place you went to and how much did they charge? Even though their facilities are limited, it might be interesting to compare measurements on the two cars from the same equipment. And I suppose when it comes down to it, power and torque at the wheels is what matters.

I'm told a standard Aero can measure at well over 200hp at the wheels.

15% is about what I've had on a previous corrected run... perhaps I should have been more specific... the guy running the road reckoned that there was between 20-30% at the flywheel on top of the readings recorded- he gets that comparison against their own dyno.

At the start he said that his road was normally pessimistic on figures... they were all very impressed at the amount of power anyway.

However, I'm not so sure how fair a test it was- the "hold it at a steady speed and match the power" technique is far more prone to heat soak losses than the "automatic" put it to the floor and plot the graph technique.

I'll arrange to get an automatic plot run done in a couple of weeks; if you're interested maybe we could book a double session for comparison, although there won't be much cost saving I imagine. I say a double session because that's the only true way to compare- the next day or week will have different temperatures, humidity atmospheric pressure etc all of which have an effect.

Previous readings prior to engine rebuild (better compression), intercooler and water injection at a different road were a corrected 248hp and 310lbft at the flywheel.

BillJ,

Thanks for the guidance and advice .. :cheesy: The car has been well maintained, to the book and documented in the service manual

I do plan on doing the 155 k service which includes a tune-up, trans fluid change,etc.

I put a K&N air-filter in it. No further mods so far

OK, Phil, list of questions coming up:


Is it manual or auto?
Do you want it to go faster in a straight line?
Do you want it to go faster through corners?
Err... do you want to be able to stop going fast when you need to? :o
Do you want it not to wander all over the place when you're cruising?
Do you want to accelerate without wheelspin and torque steer?
Or is there some other area of improvement I haven't mentioned yet?

OK, The car is an AUTO 9000 Aero :roll: 200 HP

The car loves high speed on the Highway, cruises nice

I wish to add some low-end, quickness, "pep" :o

It corners well already, Potenza Bridgestone tires do a good job

Thanks, Phil
