i run a focus rs engine in a mk6 fez and run the standard chargecooler and custom rads

problem i have is once its sat in traffic around town the chargecooler gets warm very quickly and soaks the heat up from the tubular manifold

would a intercooler set up be better for me

what are the pros and cons of both systems??????performance etc???

obvisually water injection would be used on a intercooled set up

what boost you running then if you need WI?

would of thought a charge cooler would be better whilst in traffic


intercooler needs airflow

simhopper

im on a standard frs turbo running 21/22

another reason id like to change the current set up is for space

at the min id struggle to get a gt28rs in but ideally id go for a gt30 or gt3071r

i thought that aswell

sounds like a awesome car

How much power do you need sitting in slow moving traffic ?

simhopper

but once the chargecooler is warm it does take a while for the temps to drop

only reason i ask this is engine advantages have released a intercooler kit for the frs

if you had a choice of either of the above what would you choose and the reasons why????

Rhys

I would much prefer a good Intercooler, Less to go wrong etc.

Hold up, am I the only one to ask the obvious..........

where the fuck did you get a Focus RS engine from ???!!!

Jamz

A Focus RS ?

simhopper

frs are common as shi7e now

the diff gives you a false sense of security then it bites..........theres a good few bean up for breaking

pics of the car have been hosted in the builds section

Yes mate...............

Mr S1

can't say I've seen any more than 2 or 3 but if you managed to get one mate fair play......................

so i presume your not believing him then?

sim - get a piccy up

No - didn't say that................did I ?

Mr S1

iTrader: (2)

Didn't dis-believe you before - wondered where the engine came from.............looks good fella

who cares

chargecoolers vs intercoolers

Unless you're going for over 300bhp, I would stick with the charge-cooler with an enlarged radiator.

The thing with fitting an intercooler, is that it isn't any good unless you can get plenty of airflow without restricting the radiator too much. Obviously, you also have fitment / packaging issues with an air to air one, as you don't want to ruin the look of the car by cutting bits of bumper away....

Ginge !

sim cut out were that grill is and allow some sort of venting in the bonnet

at the moment all the air is going under the car from what i can see

simhopper

im already at a estimated 300bhp and plan a little more before it goes

only thing left to do is turbo upgrade

Mark Shead

If your charge cooler pump is running all the time then fit a fan to the charge rad this will help, if you cannot contain the heat under boost then change to a Intercooler.

simhopper

thats all done along with the number plate recess has gone aswell

As you already have the charge-cooler bits, the sensible thing to do would be to get it all running and then just measure the ACTs to see if the chargecooler is coping or not. Why waste money un-necessarily? TEST don't GUESS .

Ginge !

that would have been a good point to post a sublte link to the act gauges on your site

# note, you will need 2 gauges to measure in and out temps


(i deserve commison )

The gauges are incapable of reading anything above 69.9deg, so are only suitable for post cooler temps . But nice try, and thanks for the plug .

Ginge !

its winter though so shouldnt make a difference


ok ill get the maplins link

I run both Intercooler & Charge Cooler.

The Boost goes into the Charge cooler that feeds the intercooler.

I am going to remove the Charge cooler and go for the simpler design of a large front mount intercooler. there is less to go wrong with an air to air intercooler, charge coolers need water pumps, water ect...

sat in traffic It makes no difference what charge temps go to, your not going anyware. The other way would be to remove the RS Fan assembly, which is a set of small "Suckers" and replace with some slimline 12" kenlower "blowers" on the back of the air con rad. Place them low down just behind the intercooler or charge cooler rad and it should help air flow - Oh and wire them to an overide swith on the dash so they can be permantly on in traffic..

Thats my set-up and is 110% Tops!!

vroooom ptssssh

what about an escort cossie intercoolerchargercooler you know, bit of both?

Nimmy

Had this problem with my FRS through summer. Now run an intercooler which is better then the chargecooler but doesn't help those temps whilst idling or in slow traffic. So cut a hole in the bonnet and have a manual switch for fans. Problem sorted.

There are pros and cons to both,

I mean getting very technical then you can look at the Specific heat capacity(SHC) of air against water, for instance SHC of air is 1005-1030 J/kgK but water is 4187J/kgK this means that it takes about 4 times as much energy to change the temperature of water than it does air, so when the chargecooler gets hot it stays hot longer, but it also takes longer to get hot than an intercooler would, theoretcally anyway.
the other pros and cons would be the packaging issues like Mr. Rainbird suggested, in all fairness I would be inclined to follow suggestion and see if what you already have is coping.
