Intercooler or Chargecooler?

[3sgte]

You dont need reducers if you use a toyota pump and the right size piping, surely a reducer is a restriction.......

Im not sure your getting what Jonno is saying Jim, basically the IC heat soaks almost instantly because of there location and comparitively poor airflow on a RR, so they wont drop off because theres no where for them to drop off too, whereas a CC resisits soak for a run or two then gets progressively warmer.

And Daveb, you know your wrong.............

the reducers are for the cinq rad from 32mm down to the 19/20 mm pipework so no restriction there

also regarding heatsoak on rr days
the c/c's suffer due to no cooling in the engine bay ie all the heat of the turbo and engine soaking into the c/c
try them on the road thrash the living daylights out of the car for miles and miles and then get out and touch the c/c mine has always been cold to the touch

i would imagine if there were 2 fans at the rr then they put one cooling the engine bay then the heatsoak problems with c/c would be gone

Restriction is only a factor if something needs to flow fast - I took rad cap off and looked at water flowing - looks relatively slow. Which is good - if it went too fast, it wouldn't have enough time to cool. So, don't reckon reducers are a factor.

Having said that, totally agree a Toyota pump would be a more straight forward option.

Ok now i am completely lost looks like its going to be an intercooler.

I still don't know whether i am replacing the radiator thats there or whether i am adding another one but i assume i'm adding another one as i would have pipes leading to nowhere, whereas the one thats there is used for the coolant. How do i mount it? In front of the one thats there? Also how do i run pipes from the front of the car to the rear, are there any guides on how to do this? I wouldn't know where to start, what size to get etc.

I'm pretty handy with most things but i need at least a step for a hint lol

If it's going to be an intercooler you don't need another front mount rad...

[Spidey]

If you are going for the CC, most people add another radiator - cinquecento rad came in a few different sizes (can't think of the size off hand but afaik it's in an older CC post, or I can measure it this evening). I just removed undertrays and cable tied new hose onto existing pipes and replaced trays. Other thing is to get the pump in place. I have mine in passenger side of the front bumper). With existing rads, the new rad is mostly already held in. Again, I cable tied it !

I think some may have tried it using existing rad but it's more headache.

Doing the work really ain't so bad - if you're going for it, decide first what pump you're going for and check diameter of pump connections, new rad connections and hose.

That's right, it's not a replacement radiator it's an additional radiator.

To mount it just get some metal strips, either pre-drilled or not and slap it in front of the existing coolant and air conditioning rads. You'll need to put some reducers on the rad and run the first length of pipe, otherwise you'll need to get the bumper off again.

At the moment my hoses finish under the 1st undertray until the rest of the system is complete (hopefully this weekend [-o< )

All of the info you need on routing the pipes to the engine bay, etc is on the forum, you just need to search.

HTH,

Here a pic of my rad:

DaveB - shoosh man.

Haha shoosh yourself, I wouldnt get me started again on the great intercooler/chargecooler debate!

pah! you'll still be quoting references to rs turbos which of course are pointless for our situation. plenty of testing done through this forum on modded cars and the chargecoolers have always delivered better more consistant results.

[Scotster]

Ok thats much clearer guys, thanks for the info.

Also thanks very much for the Pic Nailmonkey, its worth a 1000 words

Ok, so what i need for the moment is

A pump
Cinq Rad
Piping

Where do i get the above items? Pump from toyota? Rad from scrap yard and piping from halfords? Any idea what pump, size rad? Obviously i buy those 2 first then get the pipes after?

Here a pic of my rad:

Jesus! Are all charge cooler rads that big? Does the engine not run a little warmer now?

Steve

[nutter]

the one on the rad tec is actually wider than that. But i don't think it's as thick. I've never noticed any cooling problems, i am running a trd thermostat though.

[Scotster]

I take it its not this one...



As it has 3 inlets/outlets and yours only has 2?

Just had a look at the 2 kits on rogues site. Do you guys run it from the intercooler or just straight from filter to turbo?

Yep, that's my rad and that's where I bought it from, there was 3 outlets but the dremel came out....

Steve

Nope, runs at exactly the same temp (just going on the dashboard water temp gauge)

Edit: the 3rd outlet isn't actually an outlet, it's just designed to look like one.

[Scotster]

Ok now i'm getting somewhere.

Where did you get the piping/reducers etc?

Are you going to run it through your intercooler too or just get rid of the intercooler and just use the chargecooler?

Rogue motorsport have just fitted a RADTECH front bumper rad. so will
soon give it a test.

[DaveART]

The rotary guys seem to like the PWR cooler;

Shame it doesnt really fit in the mr2 engine bay, someone i've seen has fitted it in the boot- which is ok i guess, but not so neat.

I think at the end of the day i'd prefer an intercooler in the stock location, but just from what i've heard the cc is the more efficient cooler. Water-air is always gonna work better than air-air.[/img]

Yes, the Renault lot use them too from www.chargecooler.co.uk , though you can get them in smaller sizes, depends what intake pipe diameter your using..

[philster_d]

whats the deal with heat soak on a cc, rr shows lots of it when doing back to back runs....ie, lots of power lost on 2rd, 3rd runs....
??

Interesting - on the recent ROC RR day the intercooled cars (ICs at the rear of the car on the underside) got progressively lower figures on each subsequent run, while the chargecooled car got progressively higher figures on each subsequent run (that's runs one after the other without coming off the rollers)

(Only one fan, pointed at the front of the car, though it did seem loud enough to be shifting a fair amount of air)

Mine dropped from 274 to 268 on the second power run (first run I went off the edge of the graph )

[Leon.]

Wow, a blast from the past!

So does anyone have any figures and comments about running an IC with WI? Its what I'll be doing should I need to although only aiming for 350fly probably on a ct26 TT hybrid stage 2 (currently got a GReddy IC with spal fan).

[tomwoodis]

205 cc all the way - great results!

Me neither my temp guage hasnt budged since the new radiator went infront of the existing one.

Mine also has a rad for the ac behind that and the ac is working fine too.

Are you going to run it through your intercooler too or just get rid of the intercooler and just use the chargecooler?

Just use the chargecooler buddy it will get all the results you will need. Going through IC as well will be a waste of time

[llenrub]

I haven't read the whole thread but I get the idea.

I bought a ST205, but when I gave it to my friend who builds privateer rally vehicles. He wasn't impressed so he did something else.

The fact that it sits above the engine appears pathetic and is the reason why such a large rad is used with it. So he converted the Greddy intercooler in to a chargecooler and mounted it down in the air intake. Its much bigger, out of the heat and has the additional benefit of air flowing around it. Common sense says it should be miles better.

I'll have it back in a week and we'll see!

[2barGee]

I have got a huge charge cooler and its by far the best mod i have done!!! I have got a radtec rad at the front and mine on the road stay very cold

I am running a stock ecu and i just made 275 and the wheels thanks to the cc i am running
