most of the product tests ive seen or read about that have been done, airtec usually fair very well often beating the more exspensive options (cue the M.A.D and spec r fanboys saying tests wernt done right lol)

 

ohh my dear sweet lord , im going to have go make another cuppa tea lol



this is hilarious ,

considering the spec r design cooler isnt there design !!! it was made by jenspeed !!

mark himself commented he tested one 7 years ago that ran bottom feed entry and exit feeds ,

so what exactly have they done to create a whole new cooler ??



turn it upside down pmsl !!


and on a sub note , im just tring to locate a pic from gatebil in 2005 , that ran a top feed ent /ex cooler like spec r's in a blue escos ......


i understand the mad /spec r crew are going to back there lads up ,


but id get the facts before fully slating other peoples work ect,


couldnt agree more mate ,

personally im not biased to a tuner at all , for me my car would be built with a part from every tuner in the uk if that tuners part does the job and is the most competively priced on the market ...


its been done to death in every other form of production and sales


some one undercutting someone else and then passing that product on to the customer is general practice ...


personally im happy that its starting to filter down to the cosworth market. for too long it seems the rs scene gets hit with " cossie tax " on parts , were other brands reap the benifit of cheaper performance parts ,




just my two cents worth .......


beef

 

well said beefy

 

But he is completly wrong.

Mark

 

If you cant see what is diff from the spec r one to the jenspeed one then I must suggest you should have gone to spec savers

Mark

 

heat exchanger technology, particularly fin design, has come a long way in 20 years with advances in CFD

 

im sure they have,,, so we change our old design rs500 cooler to the latest fandangled model,, we lower our air temps by 3 degrees,,, and we gain,,,,, ummm 2 hp,,, well worth the 500 quid?

 

No I have seen 30 to 40c reduction with the spec r cores at 500+hp.
Not tested one under 450hp to say on the reduction.

Mark

 

so realistically until further testing is done at least 90% of us wont see the difference or feel the benifits of the, in my eyes overpriced spec r cooler? factor in the % of us that will only use it on the road and not track then even less of us need a spec r one and would be better off with the likes of airtec if it produces the numbers

 

you don't just gain by the heat exchange being more efficient - you also gain by the compressor having to do less work

 

shhhh thats my leading question in the other post about "testing" lol

 

40 degrees reduction,,, surely you should be looking at lower the temps by using a different compressor?

 

i had an airtec rad and cooler on my rs turbo and no complaints about the rad but the cooler was shit. when i drove the car hard the temp guage used to go up very high because the cooler seriously restricted airflow to the rad. when i changed the cooler this problem stopped completely and i could cain it all day

 

Without testing it would only be a guess based on what we see on the 330+hp cars but I would expect to see a 20c reduction,
Spec r can still make the old style RS500 cores but noone asks for them now,
20c is prob 10hp on a 330hp car so its up to the owner to say if its worth it for them.

Mark

 

So your saying use a diff comp wheel to reduce airtemp when the 500 style cooler cannot cold it down,
I say fix the problem with the cooler and the onlly way you could drop it 40c with a turbo swap would mean fitting a GT42 to a GT30 car bit of a over kill.

Mark

 

sounds a fair gain, but until these are tested back to back on varying power levels i guess its all speculation anyway

 

lol

 

so what temps did you see with an rs500 intercooler,, then after fitted the fandango?

 

Correct thats why I said guess.

Mark

 

On Rods a Ades we were only seeing 7 to 8c above outside temp and about 10c on a GT3071 car and seeing 50c above outside temp on a Pro alloy int.

Mark

 

was pressure differential measured on both coolers? as thats one HELL of an improvement if DP was near as dam the same

 

We didnt measure the drop on the Pro alloy but the figs we got fot the spec r one we were very happy with.

Mark

 

Was this a pro alloy rs500 item or their 100mm?

 

RS500 one.

Mark

 

That does not surprise me, their 100mm is more on the level of spec r

We did a basic comparison on temperature only on two engines running the same turbo and boost levels and peak temperatures were only a few degrees apart but the spec r seemed to cool back down slightly better. However this was the early pro twin 50mm cores I hear the new 100mm core is better

 

how well do these compare to the std rs500 item ?

 

i think to truely evaluate an intercooler you need the following information
inlet/outlet air temps plus ambient air temps
mass flow rate
inlet/outlet pressure (and pressure differential,)
a steady airflow rate at the intercooler
relative humidity

i think without knowing all these its hard to judge which is best.
does anyone agree with me or am i just being silly?

 

You cant compare the Spec r is massively better and the figs where close to what we saw on the Pro Alloy.

Mark

 

so if you were to replace a std rs500 cooler what would you reccomend fitting ?

 

Where d'you hear that from? Cracks me up when they say 'I heard this' and 'I heard that' - bollocks.

 

That's as maybe. If I purchased this kind of product and it needed to be bent/cut to make it fit I'd make it fuck back.

 

i wouldnt if it was 300quid cheaper than its nearest rival lol

 

When I said this about the Hart inlet I was told "You just expect it to fit without any hassle?"
Rich

 

the spec r cooler aint a no hassle fit on escort cossies either especially the extra wide one which requires the crossmember to be chopped off!

 

I will just settle with my 70mm Airtec...it will be more than capable for my application.

 

nothing at all wrong with them mat

 

I know mate..My cars not a track car or strip car...And it only ever gets a quick squirt of the loud peddle.

 

I hope not as i've payed for mine of AS, now i know of Steve feels

But mine has a take off for a dump valve which i'm not sure is coming on them std

 

don't be stupid and bring science into it

 

Your worried about a £40 difference. So £360 ish when mine was about £700
