Following on from Lee Reynolds thread ad the converstaion I was having with James (EIL132) I have pretty much decided on the 4x4 Cos intercooler converison, which necesitates (sp) custom short-height rad and reversed charge-carrier for single pass set up, ala;





Now this, I'm told, fits beautifully behiond the S1 grille, and with the half height rad (so that the cooler sits on top of the rad, not in front of it) there's no engine cooling issues, and the i/c is in prime location for maximum air flow.....

BUT!

Now I've been looking at EsCos inter/charge coolers



Is this gonna be worth it or is there no real difference over the Saff 4x4 one, and how much longer is it than the Saff cooler, as if it's much longer it might not clear my headlights



(Also, does anyone (inc tuner or breaker) have a knackered or damaged EsCos cooler I could have to fook about with to see how it might fit?)

 

Thrush

I dont profess to know owt...so this might be irrelivant BUT fron this pic



wouldnt there be a lot of heat soak being so close to the turbo????

 

That had crossed my mind..... Pondering on the idea of a plate between turbo and cooler to try and deflect some heat away - but not sure how this might disrupt air flow through intercooler

anyway - can anyone give me measurements of the difference in length between the two coolers? Cos last thing I wanna do is buy one for £40-£50 and it have no chance of fitting

 

I do a lot of in traffic driving as its my everyday motor...so id be concerned over that!

Juts ordered my GRS now

 

GRS i'd say

 

Mine don't and won't be doing much driving at all As it ain't a daily driver.....

I did think of the GRS, but tbh, for reasons outlined in the other thread - I prefer the Cossie cooler for the single pass set up and cos it don't overlap a radiator like the GRS does.... I knowthe 4x4 coolers have a very efficient BERH core and for the ammount of boost I should be running (current 12, but max probably ever be will be 18 tops) I don't belive I need to full size of the GRS one...... Plus I like the look of the reverse charge carrier

Had a look just now with the 4x4 cooler I got and judging by the pic of the EsCos one, I don't think it will fit, in relation to the charge carrier.... so std 4x4 it looks like it is

 

Cool.

Will that smaller Rad be up to the extra cooling tho Thrush?

 

Well according to Scott, it is longer (due to no intercooler on one side) and thicker so it should keep to the same level of capacity IIRC..... I'll probably bung a couple of 8" / 10" fans on it tho to be sure.....

Still not sure if fitting a metal plate between turbo and cooler would disrupt airflow around cooler

 

The only time i have noticed heat soak is at standstill, once you are moving and there is air flowing through the intercooler, the temps drop very quickly below 40 degrees, Unfortunatly there isnt a great deal you can do with the front of a S1, especialy if you dont want to cut about the front of the car. The thicker rad does work as efficient as the standard height item, how ever once you are at a standstill again the heat build up does happen quicker due to surface area being smaller, so any breeze that 'may' help keep it cooler in traffic isnt as helpfull.
I have fitted to mine a 9" kenlowe fan, fitted on the front left of the rad and a Pacet 10" fan on the right hand rear, when both are on there is ALOT of air being forced through the rad, Temps do drop fairly quickly, and normally in traffic the temp guage, with both fans on, on a hot day wont go over 3/4.

I have designed mine in this way as its predominatly a track car and is hardly ever used on the road, but there is no reason why it cannot be fitted to a road car especially if its only running a stage 1 chip. And its something abit different. Its the first time i have seen anyone trying to progress the intercooler options for the S1 in along time.

 

Some pics of my GRS setup on my Orion. As a comment, removing the standard S1/mk1 Orion type of front grill makes a HUGE difference in water and underbonnet temperatures. I know it's a big NO NO for S1 people but modding it will make big improvements. Might be a good idea to do a cut-out version for track days.

 

oi thrush that my picture

oh by the way there 50 mins left on my auction on that cooler

http://cgi.ebay.co.uk/ws/eBayISAPI.d...e=STRK:MESE:IT

 

oh and it does fit

some minor trimming to the front panel which put the cooler virtually flat behind the grills, it clears the headlights no problem, a few bits of welding needs to be done and thats it, bits only need to be changed if you want to use the standard height rad, as the outlet pipes dont quite clear the end tanks of the radiator.

 

oh and for info i was going to do it reverse of how it is in the picture, the chargecooler on the right.

as there's alot more room on the right hand side of the engine bay.

Oh the designs and things i had planned for my track car

and now its gone

 

pro alloy...
no water temp probs.. no inlet temp probs... no reverse carrier.... no high boost probs...single pass... standard hoses... no expensive fitting bills... no jacking up bonnets....don't need to move the water rad..... fans included

www.proalloy.co.uk

 

And no money left in the bank Sorry Wayne, jsut cannot afford it fella

Gonna go for the 4x4 one I think, rather than the GRS or EsCos charge/intercooler....

now mine as it is now highest it goes to is 2thirds under lots of heavy boost driving (on hot ambient temp/high humidity days) and MAX 3/4 in traffic/standstill if the fan is on....

So is this good? I always thought that was a bit hot TBH But then I am only used to my 3i which never even saw half way and my last S1 the rad was fooked and was in the red within mins after you first get boost

 

thrush i got a 2wd cossie coller with 1 end tank cut, turned and welded im not gonna be using if ya want it 80 quid som i get me money back, remeber i had to have it cut and ally welded though hence the price

 

2WD no good for me Ginge, plus if me bro don't use the one he got then I got a 4x4 one for £30 Also, what do ya mean by "cut and turned" ???

 

end can was cut and turned, look at jame's site and ya will see

 

addy?

 

eil132.com

how long ya been talking to him for

 

Tried that - said no page found, so thought it had changed or summat

 

Right had a look - no good to me at all Ginge - since with the S1 you mount it up top rather than down below like the S2..... So having the outlet port turned means the boost hose would have to come up thru bonnet

Can't see it catching on

 

lol!

Thrush that sounds like its geting hot mate. Mine (b4 the sender went 2 days ago) never got above just higher than middle in traffic. And your turbo aint water cooled so 'should' run lower temps???
