Dear Craig,
The Cossie is strong, but I don't want to have to cut short my track time because the engine is getting too hot. The mods are there to keep everything as cool as possible when giving it EVERYTHING. Before the oil cooler was fitted, by the end of the session the oil would get up to 130+°C at which point it would cause a top-end (6000+ revs) misfire). Obviosuly not wanting to have to slow down (so the Scooby boys could catch up again!), I fitted the Laminova cooler which has dropped the temp down to 110°C when used hard. The water cooling has also been removed from the turbo (to stop it from heating the cooling system) and the radiator is double the size of a standard one.....

With regard to calling me a lucky *******, which car are you referring to?

Best regards
Mike

Dear Craig,
Shurly shome mishtake, you actually saying that! I know - its another wind up!

Mike,

Now you are making me laugh out loud

This is possibly the most amusing thread ever on the BBS. You are indeed fit to grace these web pages and a true petrol head

(Still an ugly B*****d though )

Cheers.

Dear Diablo,
I just hope that for your sake you are a "looker", 'cos if I ever get to meet you I will be taking photos to put on the board, just so everyone can see how "attractive" you are!

Anyway, at least I'm in a real car (as in a FORD!) - that particular one happens to be THE car that holds the 0-60 record (mean of 3.07s!) and all with a palty 480 bhp (but £35,000 worth of XTrac transmission - girly 4wd again!). It will soon have over 700bhp, as the owner has decided to run it on "rocket fuel" (rally term for the high octane stuff that the works teams use 107 RON and £20 a gallon!), so that he can re-take the 0-100-0 record (lost to a COSWORTH! powered Dax Rush). See our May 99 Newsletter for a write up of the ride I had in it!

In fact why don't you have a read about our club and my car by looking at the following:
January 99
Article entitled "The Need for Speed"

March 99
"The Need for Speed - Update"

May 99
"Father Christmas Pod" (Our group goes to Santa Pod).

June 99
"Revs Top Speed Shoot-out"

July 99
"The Need for Speed"

August 99
"The Need for Speed"
"Ultimate Street Car"

Once read, please let me know what you think... (I can take it!)

For such a great handling car there do seem to be a very large number of Imprezas written off on track days and normal roads.

Somebody posted something about a salesman showing off to a customer and destroying the car, and I have heard of quite a few others going the same way.

Have I misjudged the number of write offs or have are a lot of owners onto their second Scoobie already?

this is not intended to be inflamatory but I certainly have the impression that the car tends to bite back hard.

Dear Anders,
What I have learned is that "off the shelf" chips are a total waste of time. Every single engine (even of EXACTLY the same type) is DIFFERENT. Some will make more than the quoted bhp and some less. Obviously a "guestimate" chip does not have the capability to take any of this into account. Even the ones that can be adjusted on the rolling road are a waste of time, as the conditions on the dyno fluctuate and cannot be kept at a constant level. The ONLY way to map a plot accurately for any car is to take the engine out and put it on a proper bench dyno (you don't see the BTCC / Formula 1 teams mapping on a rolling road!). This way you can replicate any situation over and over again, take the engine to its absolute limit (by listening for the detonation with head phones plumbed into the engine). This way, you know when the engine / injectors / cams / turbo have reached their limit. As an example, say it starts to go lean at 35psi at 4000 revs, this can be seen on the lap top (and heard through the det. cans), so you know that to go above this boost would be detrimental to the engine. Accordingly at this point in the curve either more fuel could be added or the boost could be backed off by a couple of pounds for a degree of safety. You can then take the engine back to the identical position and loading to see if this has made a positive increase to the engine or made things worse. This is done at 500 rev incriments until the engine has been remapped to suit the new components that have been fitted and then engine runs at its most efficient at every 500rpm increment. This obviously allows you to try loads of different permetations to get the absolute best out of the engine (more fuel, less fuel, more ignition, less ignition, more boost, less boost etc. etc.). You then get a perfect curve that has the settings stored in the memory of the lap top. These can then be "burned" into an ordinary chip, and you then have a program that has been designed SPECIFICALLY for your car and your modifications and more importantly YOUR engine. Harvey has built engines to IDENTICAL specifications and they can still vary by 5-10bhp, for no other reason than no two engines are ever truly identical (just like people!). This is why you should have it done properly and why your engine has let you down....

If you require any proper advice on mapping the ECU, you should speak to Ahmed Bayjoo, he works in conjunction with Pectel (the engine management people) and is employed (free lance) by many blue chip companies to help them with their mapping. Harvey Gibbs is where he takes all his engines to be mapped as it is one of only a handful of engine dynos in the country that can be used by the general public (Harvey is also a superb engine builder in his own right, being responsible fo EVERYTHING on my car apart from the mapping which was done by Ahmed).

Hope this helps.
Best regards

Hi guys...

I managed to drag myself away from my young 18 year old girlfriend.. *oh what a hard ....life*

I agree with Mike... every car is slightly different.. but I would like to say that, the skill is knowing what the weaknesses are in an engine..and knowing how to operate within then. If you are going to completely rebuild the engine then fine...you know the base to start from, you have eliminated the weaknesses (well, actually moved them to else where) - This is why you go to a Tuners (specialist), you are meant to be paying for their expertise and knowledge..*tries not to laugh*

The problem most scoob tuners will have, is lack of experience... how long have these tuners been working on Scoobs ? a year..maybe two... That is the problem... they are after money.... how much development work did PE do into the ECU and the engine ? not much if they dont know the internals of the Impreza engine... the same goes with GGR... they have never modded an engine.... they have rebuilt one for someone....cant remember why though.

Another problem is that the Scoob changes quite alot... introduces new technologies and weaknesses...and remves old ones.... its difficult unless you stand from scratch

A few people slagged off the Jap tuners... but they have got it right... they go internal...sort out the weaknesses... yes it costs more....but we arent talking about a 2K R5 GT....we are talking about 20K's (40K in Anders case) of car.... do the good right... or at least plan it... dont suddenly go for a product when it comes on the scene...

I know this is all common sense sort of stuff.... *shrugs*... But its this sort of stuff thats over looked...

Anyways...

Dear Mr Mike RuinsBirds.

I would like to point out that Pete Croney's incident was a direct result of fuel spilt on the track by another car which was not black flagged as allegedly the marshalls had disappeared.

My 22B was trailered back, before that fueling was adjusted it had been fine for 29,000 miles managing 0-60 in arround 4-4.4 seconds.

Not being a true petrol head I never bothered with the quater mile as I would end up on a ban sooner or later and I need a car to get to my various hospitals!

My engine failed 600 miles after it was remapped.

Now on a serious note, it is becomming apparent that so called safe tuning options via remapping are far from safe or imune to potentially dire consequences!

What advice can you give to Impreza owners out there regarding stage1/stage2 tunes?

I.E. what lessons have been learn't in the Cosworth game?

Have Cosworth failures moved in to the next market?

Dear Weaver,
Thanks for the compliment, and although I am happy to supply bits and pieces through the company that I am a partner in (R & B Motorsport - as a side-line to my every day job), I would NEVER profess to being expert enough to carry out the work that I only have a "limited" knowledge of, prefering to leave this to people (such as Ahmed and Harvey) who really know what they are talking about. There are already too many self-professed experts out there who are only too happy to rip people off and then run and hide when things go wrong, leaving people stranded with cars that are useless to drive (if they can be driven at all!). I would rather hold my hand up and say that although I have a "passing" knowledge (just speak to Ahmed, and then you will feel that you know very little!), I do not feel "qualified" enough to work on the cars. That way I know I can sleep easy at night with a clear conscience! However, with my limited knowledge, I can at least point people in the right directions and share MY experiences. Frighteningly enough, there are STILL a few supposed reputable companies that profess to know lots, but when it comes to the proof of the pudding their programming is complete s h i t e and worked well, once and on one car, so they used that as the model for every conversion since (scary).

I would point out that there are a couple of owners in your club that have got the "right" idea. The one whose brains I would pick is Mark with R19KET (Possum equiped car). He has gradually fettled the car into an exceptionally quick Scooby (by himself) and would be able to tell you how best to go about it. He has self programmed the ECU in gradual steps to get the performance that it now has. However, you cannot run before you walk, and he has lots of other little tricks to help him achieve the "perfect" map and to protect the engine from letting go. Eg. a digital exhaust gas temperature gauge (which will give you warning when the engine is about to go into terminal melt-down mode! - Stay below 900°C and you should be okay...), a proper fuelling meter which tells him when the car is running lean / rich or spot on, and an accurate digital boost gauge which can record peak boost etc.

I could (and would) listen to the likes of people like him all day, as the car has done the miles and is still in one piece (proof of the pudding so to speak). Therefore ANY mods should really have these precautions in place before carrying out the work, and then you can "see" if thinks work or are stressing the engine. NEVER, NEVER by a chip for a Scooby - you're asking for trouble. The Possum ECU (or equivalent) is THE way to go (and no, I don't sell them!).
Best regards
Mike

Mike,

Clubs like yours need time and effort as well as just enthusiasm and its nice to see you guys taking the time to write all that up on your web pages.

(Must have lots of free time while your Cossies are in the repair shop )

Seriously though, ever thought of placing some pictures in the newsletters to illustrate the antics?

As far as being a looker? me? Hah Hah. I'm even uglier that you

Hey Mike and all,
Haven't checked the BBS all weekend cos I've been away. The nice nurse's even gave me a lovely white coat to wear and lots of yummy smarties to stop me being silly while I was in the room with the soft walls .
It's not good when you hear of stories such as Anders, if I remember rightly this was how the Cossie got it's reputation for popping engines. Bad chips kill engines faster than anything else. Read your posting abot engine dynos etc. spot on mate...ever thought of setting up your own company you've certainly got the knowledge and enthusiasm. Having read the other thread about the situation it's sad when a supposedly reputable company treats a customer like this and one who has obviously spent a relatively large amount of money with them. Are there any instances of this happening previously on Cossies and what was the outcome?

Right back to the important stuff

1. I told you it'd be tuned
2. Crashed on spilt fuel, are you sure you weren't there and it was diff oil!
Keep it coming
Regards
Luke

i have to agree with mike completely on the engine front. I have vast experience of competition cars, including Group A cossie and prototype V8's.
The secret to power output and SAFETY on a turbo engine is the mapping.
I do all the mechanical engine building etc, but when it comes to mapping i use the experts. My 350BHP road cossie uses an Ahmed Bajoo mapped ECU with the correct flow rate injectors and 3 Bar MAP sensor etc.
My group A Cossie forest rally car uses a mountune Group A high compression, Elf fuel mapped ECU with ALS and WI.
It took a couple of years of very expensive mistakes with the cossie to weed out the rip off merchants in cossie tuning. I suspect the same will apply to the impreza. All i can say is buyer beware, dont believe a word anyone says untill there is substantial history with the conversions available.
Finally, remember the cossie was designed with Group A racing in mind, the impreza most certainly wasn't.

Dear All,
Thanks to one of YOUR postings (thanks Simon!), I have just heard that the Cossie has just been voted No.1 in the latest Top Gear Magazine report. What can I say (apart from the magazine is s h i t e - which is why I have to rely on the likes of Scooby owners to read it ).

Your comments on the review would be most appreciated, as I have yet to read it!
Best regards
Mike

Dear Stef,
Don't own an RSOC baseball cap, and no it isn't an M5. All I can tell you (without you taking the ****) is that it's turboed and 280bhp totally unmodified.....
And if it is that cold, I will be in the car positioned as close to the track as I can get!

It wouldn't have 4WD would it and a name beginning with 'S' and ending in 'ubaru'?
If it has I've got a nice dress you can borrow especially for those 4WD occasions

Dear Stef,
Have entered a team in the karting for 5th Dec (so Craig if you reading, I'll be able to show you how to drive properly - as in rwd!). Can anyone tell me the format of the karts (i.e. engine size, and configeration - twin engined, single, positioned behind, or beside the driver etc.?).

Thanks
Mike

As I've said before, a thread with this title could really run indefinitely as there is always jovial banter to be had with Rainbowman & Co.
Not so sure it'll be so jovial if he breaks another diff' on Sunday though, especially if it goes when he's running against ME!!!

Stef.
PS Anyone got a hacksaw I can borrow?

Dear All,
I will be at Donnington at about 10.00am, and as I would only recognise Stef's car ('cos of his dodgy number plate!), could you please look out for me and come and say hello. Will be in red thing: M5 MJR as I can't be a r s e d to a swap the diffs over on the Cossie seeing as Santa Pod is the following day.
Thanks

Perhaps you should wear something recognisable, like a RSOC baseball cap or something, as you're unlikely to sit in whatever it is all day!
IS it a new M5 you're coming in, or just a coincedental reg?

btw - slightly off the point here, and based on the comment about the numberplate...Stef - were you at Silverstone last year in a green scoob?? If so - Ive never ever seen 1 car, with so many people in it, in so many gravel traps!! You were an entertaining pub story for several weeks afterwards!

Nightmare.

I do have a green 4 dr and I was at Silverstone THIS year, but was not allowed to take passengers.
However, I was at a track day at Donington earlier this year when I managed to spin into the gravel with THREE passengers on board!!
It was only the one gravel trap though!!
It was the last lap of the session and my tyres were completely poo due to the heat (excuses, excuses!), when I simply gave it too much too soon out of Coppice or Macleans (the blind right hander beofre the main straight).
I was still relatively new to track days (obviously! ) but no damage was done.
It was, in fact, the last time I have ventured into such territory. The 'sideways' tag has remained since. I do not intend to go there again though!
If it's not this occasion that you are referring to, it wasn't me you're thinking of and ignore this reply altogether!!!

Dear Stef,
To achieve that time it would have to have a power to weigth ratio of in excess of 400bhp per tonne! So unsurprisingly I DON'T believe it (and I'm sure you don't either).

Dear Craig,
I'm sure you'll get to hear what the car is...

Dear Liam,
If I was going to spend that kind of money, then I would get an F1 Le Mans (700bhp and shorter gearing!). Apparently the insurance for a boggo F1 is £36,000 p.a. for someone my age etc....(ouch!). But then again if you can afford the £25k services (and the car!) this would be a drop in the ocean!
