General Stilo Specs?

[alfanige]

Even with running an additional 120bhp over standard on the 2.4 doesn't cause it to overheat. We have never had any problems long term or short term on any car, on the road or on the track.

Our test Alfa has done 95k of which 80k has been at over 200bhp, demonstration runs, testing, track runs, etc all without heating issues. I hhave had Fabia vRS at 190bhp round and round airfields until the tank run almost empty and it did not waiver more than a couple of degrees over normal, which would be expected given the sound thrashing it got.

Not a single customer has come back and advised their car has run hot, be it petrol or diesel.

It would be interesting to know where you got your information from, no doubt some PC whizz on a forum somewhere who instantly became a tuning wizzard with hearsay from a mates mate, who heard a bloke talking in a pub.....

I am not just speaking on behalf of ourselves, the same applies to any tuning company! If you drive the car hard, you will work your cooling system harder so if it is not up to scratch it will be found lacking as it would if you caned the car anyway.

Oh dear confusing isn't it?

Not really, but thanks for the derisary comments anyway

I am aware of BMW's 2.0d and 3.0d's being a problem because they already run a high state of tune. It seems the assumed 'safety margin' was not as big as expected and so models with a remap suffered problems once getting to around 100,000 miles. The reason I did not quote manufacturers on here was that along with BMW there was another marque but I can't remember which, so rather than 'bulling' away I tried to keep to the facts as best as possible (I think from my post you can tell I am not the most mechanically minded person). Others on here may choose to 'bull' their way through, but I don't.

My mates Octavia vRS (236bhp from 180) did suffer from overheating problems. This might be due to a problem with the cooling system anyway, as Nige suggests, but remapping it is likely to have exhaserbated the problem. Not to mention the problems with the clutch slipping on his car too. This is an engine that in standard tune can do 225bhp (or is it 237bhp with the new TT Sport?) so there is clearly more work required on some cars than plugging it in to a lap-top.

I am not saying it WILL go 'pop', but I am just suggesting people need to have their eyes open.

So where did you get the information from? The problem is that someone else will read your comments and instantly themselves become a forum technical guru elsewhere beleiving it to be true and so on.

The BMW 2.0d and 3.0d do not suffer from any overheating problems and they are not running in a high state of tune, far far from it. The 3.0d can take 260bhp day in day out as we have proven with a 330d auto that has now done over 80k since being remapped (now well into 130k in total). The 2.0d, which is used in many other applications, such as the Freelander and Rover /MG 75 can also be taken to much higher outputs again without issue.

The 1.8T is a slightly different situation. You HAVE to make other modifications to take them more than 45bhp over the standard output, the same as you would if you wanted to go higher than a safe margin on anything else. If the people that tuned his car didnt warn him of that or if he didnt head their advice then that is a different story

I wasn't having a pop at you personally, just the fact that you get posts like yours on forums from people who know how to open a lap top but not how to open a bonnet.This helps no-one and just spreads bull**** further.

I take advice as you clearly know more than I.

It's a shame that people aren't allowed to pass-on information they have gained. If there is then evidence supporting remaps (and the evidence you have of the cars you have 'done' is very useful) then that is all well and good, but some of us (me) with more negative aspects need to be convinced further.

There are those of us who understand the principles of thermodynamics and how a turbo works that may take longer to catch up with the 'win-win' principle or remaps. The gains we see on N/A cars (5%) seem perfectly reasonable within a standard engine (I suspect manufactuing tollerences won't be far of this anyway) but adding what can be 40% seems to require more than changing the fueling and air capacity.

It's a shame that nobody is willing to convince me with an understanding of what happens; the better solution seems to simply marginalise me. Shame

You were "marginalised" simply because you seem to have posted what is incorrect, hearsay and nothing based on any fact.

N/A engines can be taken up more than 5% as well, we have 320i's on the dyno at over 15% increase on standard, again going very strongly without any issues many miles and years afterwards.

The heat of the engine is dissipated by the cooling system, a cooling system that is designed to work in extremes of temperature without modification AND designed to tow, in some cases up to 1500kg, then you will see how much over engineering is put into modern cars.

I am coming from a point of experience of doing the work on cars, and we have not had any of the issues that you seem to be privy to from your sources, nor have I heard any stories of any other tuners having had any issues, so may I ask again where your information comes from?

I grant you that 15 years ago with an old belt driven fan on a old Sierra (Ok they were viscous but I am making a point lol) pulling an old Eclipse up Cumbria may well be seen with the bonnet up and a perplexed pipe smoker looking into the steam wandering what went wrong.... but you don’t get that now (and not because smoking pipes is unpopular)

Once again, I am not having a pop at you personally, just want to know what source of fact you gleaned your information from so I may check it out and see if there is anything we need to be concerned about as I am more than prepared to learn from the experience of others if it will help us overcome or be aware of anything new.
