Couple of quick questions for those who've upgraded to a full front
mounted intercooler on their series 1.

What cooler are you using?

what fan do you use?

A mate is thinking of buying one for his mk3 project, and seein as you lot are a font
of usefull knowledge thought i'd see if anyone has any recommendations, or have good/bad experiences when using one!


CheeRS in advance.

JesseT

GRS on my mk3. Here's two pictures that tell you quite much about fitting it. Never mind the red color car. The pictures are from a time when it was in my mk1 Orion.



So minor cutting and bending for the front panel to fit two 10" Kenlowes. Also the front mask need to be finetuned from the back and the lower mounts need to be cut. It's a bit easier with a single fan.

gaz s1

pro alloy front mount with the fans supplied with the cooler no issues whatsoever fits perfect didnt have to cut front panal either, no temp issues either so no horrible jacked up bonnet.

timturbo

ive heard gd things bout grs front mount but then u have buy fans seperately and comes out cheaper than pro alloy ones

PeterD

Ive got the pro alloy i/c and rad kit, its very good and pro alloy's customer service and warrenty work is bang on

timturbo

how easy to fit mate? do u have fan operated switch?

SafeChav

JesseT, have you got any pictures of the other side, from within the engine bay.

Ive always wondered how the rad etc bolts up, theres so little room in the front panel of a MK3.

I just cut mine out

JesseT

The rad bolts as usual and does not need any mods. The IC is not bolted to anything, it's just pushed tight to its place by the rad.

SafeChav

really?

I would never of thought it would fit! Most series 1's have issues with the OE fan alone catching the front panel

PeterD

not too hard to fit tim but i you would probably need to cut the from panel to fit well as per the pics at the top of the post.

one thing i would say though is while your at it try and get a hold of an 82 degree thermostat.

a good way to go would be to have it more like the s2 kit and find a way to hold your fans onto the radiator behind the cooler instead of in front of the cooler.

the theory being that the when the fans kick in at 90 degs they then have to blow through the cooler to the rad which if your sitting in traffic will warm up anyway, the fan cowlins also can deflect a bit of air around them when you have a set of more compact 10 inch jobs, not causing a massive problem but id presume the benifits of what ive just aid would be a bit of a bonus. might even get a free pony or two through the cooler

timturbo

yer mate thats a gd idea ive seen fans on rad and wondered why as see dem on cooler why use an 82 thermostat?

PeterD

mainly just so it opens earlier.

so you can be run the coolant through the system a bit earlier, through the rad and fans then the engine.

helps when just pootling about if your rst's tuned and generating more heat which is sometimes the case with a big front mount i/c blocking the airflow thru the rad in traffic or just sitting about.

Jake tell the P to get a GRS

orion_rst

So u're saying that between rad and the front mount i/c there will be no fans. Doesn't it create problems with hot engine temp in this way? Especially in warm countries like the one I live in.

Cause I might go for a custom made i/c or fit something like from a Mitsubishi EVO if possible, below the radiator with custom brackets to make it fit in the middle of the bumper. What do you think guys?

JesseT

Yes, the temperatures might go up if sitting in traffic, but the S1 has less room than S2 in the front and it's very hard to fit the fans in between the rad and IC.
Optimum would be not to put them one after another, but custom make something that would put the IC and rad over each other like the Cossie has as standard. Someone had this arrangement in an S1 here. i still have the pictures on my hard drive.

orion_rst

Could you please send them to me? Or post them here please? I would really appreciate it.

Do you know any details about this intercooler or who fabricated it for him? Thanks

Btw... looks like you have megasquirt. Do you recommend it? Is it difficult to setup/adjust?

orion_rst

In the meantime I checked on Forge Motorsport website and they make some universal intercoolers that might suit my needs. What do you think about forge intercoolers?

JesseT

Found them:



It's only a 4x4 Cossie cooler by hte looks of it, so not the best possible, but the idea is good for an everyday car in a hot country.

JesseT

I get this type of questions all the time. It's like any other ecu out there with the exception of being open-source and it costs ~100£. It's just as good as the guy who installs and maps it. Ability to read adn understand instructions is also mandatory for whoever is fitting it.
Some good things for RST's is that it can directly use all the cvh efi hardware (flywheel, ignition, sensors, idle valve, etc.), and also support the turbo related things (mappable amal-valve, charge temp based ignition timing, can use cheap (~20£) Motorola 2.5bar, 3bar, 4bar maps etc.).

SafeChav

JesseT, that radiator in those pictures must be tiny in height. Who's car was that?

MJC

That is Scott R's S1. The rad is not as high, but it is wider and twice the depth . I have the same setup on my S1 as does Shawn. Works very well

SafeChav

Where can you get that setup from? I like the look of that

PeterD

stick to mk3 parts ya purist bastid

seconded though, what kind of power levels are going through that lot?

Get ya facts right you Mk4 WANABE

Look at the pictures it is on a Mk3, maybe u just dont know what a proper Mk3 should look like

MJC

It is all custom made. Consists of a custom made rad, modified 4x4 cossy cooler, reverse charge carrier and two 8inch fans. I'm personally, only running 14psi of boost. But there is the potential to run much more. I would have thought it would be fine up too 25psi or so. Sadly my engine and fueling isn't up to that sort of spec though

orion_rst

Thanks for the pics JesseT. But I don't think that's capable for my intentions... I use it mainly for drag racing and maybe a ride on sunday, but definitely not for everyday. I think a Pace double size intercooler would be more efficient than that. What do you think?

However I was thinking of something even better... maybe something universal like Forge Motorsport have (although I fancy more GRS, like everybody afterall!). I saw one on a Vauxhall Nova or old Corsa I don't know exactly but the front of the car is very similar to that of an Escort MK3. The intercooler was situated starting from behind the bumper and stretching further below, leaving from the top of the bumper upwards clear for the rad. And it was pretty wide in size

MJC

The cossy cooler setup is far superior to a double capasity pace cooler!" I wouldn't have spent £500 on it otherwise The double capacity pace coolers are pants. The GRS etc front mount coolers on the other hand are very good and will handle what ever you can chuck at it. I wouldn't have thought my cossy cooler is far off the performance of a GRS and there is no pressure drop across this cooler what so ever

orion_rst

Thanks MJC. But is it a standard Cossie cooler or is it modified? And from where can I buy one please? Cause if it is as much capable I would solve a big headache!

MJC

It is a standard 4x4 cossy cooler with the end tank modified to suit the rs turbo. You can't actually buy this setup off the shelf as its all custom made. Your easiest option would be to go for a GRS front mount cooler. They are about £300 and then you will need twin slim line fans about about £200 total. All this is available off the shelf!"

vroooom ptssssh

Ive saw a 2wd cos rad (looks simmilar to the one on scott R's if its not one?) with a twin 2wd cooler setup on an S1, cutting of ront panel and nearly all of the grill was gut away to get it to fit tho!
