checkin out to see if any body out here has a chargecooler in the mr2 on gt4 celica just thinkin should be of huge benefit on paper comments please lads lassies and dogs

I had a ST205cc in my last 2 - kept intake temps very low.

Was so good that I am going to put one in my current 2 as well.

Some see it as a lot of work to install - I don't think its too bad - you'd get the whole install done in a day.

I'll try look later butI think there were a few CC vs IC threads on IMOC over the years.

The way I look at it was that Toyota put a CC in their GT4 rally car, so it must have been efficient. I know the core was probably thicker etc but the point is that they chose a CC over an IC.

Some CC setups allow for a very tidy looking piping setup also

The above ones are aftermarket setup, the below one is GT4:

one more for good luck..

This guy (in the USA) is making 736whp too so apparently cc's work pretty good..

Thanks, Quandry - you've just answered a question I had. The St205CC does fit with the TRD brace

haha cool

deadly lads good advice my mechanic reckons it not a big job to do and should go in no bother i wonderin do ya need to take intercooler out or can ya run both??

You couldn't run both at once without a lot of joining pipes, and it would not actually help you any.. That said you wouldn't have to take the old intercooler out, it could just sit there disconnected. Depends how clean you want your engine bay to be.

Yes, as Quandry said - doesn't make sense to leave it in. Stock IC isn't great anyway and extra piping would make it very messy, possibly more lag etc

On my last 2, I took out the stock IC and I'll be doing the same again on my current 2. And with it out of the way, with the extra space you can get more air in for general engine bay cooling.

You wouldn't want to run with the CC and the IC...

One of the biggest benefits of the ST205CC is reduction in lag, due to the very short inductiontract between the turbo and the intake manifold. Pushign the air through a side-mount (which will also heatsoak) would be rather counter productive

But yes, get an ST205CC. I love mine... highly recommended

Where did you mount your pump ? Last time, I mounted mine inside front bumper passenger side. This time, I was thinking of mounting it in the engine bay, down near pass side intake vent.

Mine was put on by 3S / Toyota GT when the last owner had it, and they put the pump onto the gearbox

Cool - I'll definitely do it that way then

I got a little eBay air temp sensor - must put it in when I am installing my CC.

Although, the more gauges you have, the more paranoid you get watching them and worrying !!

thats all i needed to know thanks alot

right lads did ya hear this onei was talking to rally machanaic workin on a gt4 rally car today asked him about the chargecoolers he showed me his one uprated 6000 euro one on the celica and said they nearly arent needed in this country because of the weather basically he thought i was mad to do as he reckoned whatever benefits u get the car will be much harder on go go juice he reckons it like drivin half choke all the time he also said it would need a water line to it for it to run good dunno but i inclined to take his word for it

Yes you need to run a water pump etc, not sure why he thinks they're worse than a sidemount for air restriction though..

That doesn't make sense, then again, if your paying €6000 for a charge cooler, perhaps alot of things don't make sense.

Spidey has done this mod on an MR2 and his impression seemed good.

That sounds like he is saying it wouldn't run great without the water cooling - but it would run good with it ?

No-one was ever suggesting running it without water cooling !! If you run it without water - yes, it would be crap because sitting over the engine and no air or water cooling. And because you'd be feeding hot air back in, it would be like running on half choke ! But, we're not suggesting to run it without water cooling.

But once you run it with water, it cools very efficiently (up to a point - think people say the ST205 CC is good up to around 450hp).

Last time I had mine, I done a very hard run from Dublin 15 down to Westward for a Dyno Day - so, a 45 min run down and lots of boost ! When I got down, I was able to put my finger in the water and it was barely luke warm

I'm not disputing what your mechanic said - I just don't understand the points the mechanic made - why would we not need them with Irish weather. Climate isn't tropical but after hard driving, intake temps will go up.

Not sure either why its harder on juice - because of extra weight ?? CC and IC prob similar weight. So, only extra is weight is hose, front rad and pump. Maybe 5kg ?? In a 1200kg car, 5kg is an extra 0.4% weight increase.

Yep - a 6000 euro CC isn't needed. But picking up a second hand ST205CC for 200 quid is a huge improvement over the not so great stock IC.

haha

Lads, if you have an uprated IC though, a good fat one, is it then worth going CC? I cant really see that it is unless ur running stock IC.

A good aftermarket IC should be fine. A CC will have a slight advantage for city/traffic driving where you are not getting any airflow on the IC.

IMHO, a lot of mods make differences on the track or the 1/4 mile - even these are about shaving off fractions of a second etc. For Road cars, the differences will be negligible.

The way I see it - heat is the enemy of an engine - so, I want to cool intake temps as much as I can - not so much for performance but for longetivity.

Cheers Rob, in that case im happy enough with my IC, may just get a pair of Bomex scoops for more air forced down both sides, fir induction and for IC....sweet.

The thing with the ST205 unit is it gives you about the shortest induction tract you could possibly wish for... this in turn reduces your lag, making your car more usable on the road

For that alone, it's really worth considering over and aftermarket SMIC IMO

ok lads calm down sorry i got bit mixed up i know ya need the water system with the cc but really what he is sayin that the advantages of the low intake temps means the engine will use more petrol am i right i not a mechanic or know much about it and he is the only person who has said he couldn really see the benefits but this man is a toyota nut and that why i wary i know it do no harm to car and could benefit itbut is it relly worth the hassle he has a stock cc there for a hundred but it really iis nearly 6000 euro for uprated cc for the rally celica ok slipsliderg

In high boost applications fuel density is sometimes used to offset excess heat. Therefore if you use a CC keeping the charge cooler, you use less fuel. I can't really think of any scenario where it's going to use more fuel, unless you factored in the electrical draw of running the coolant pump, which is likely to be pretty low..

Don't worry - no-one is annoyed - we don't do annoyed on mr2.ie

I think people were just confused, thats all

Yeah, the standard st205 CC costs about 2600 euros new, so I'd belive a rally version costing 6k. I got mine core for about 200 euros - so, for that price, I think its worth it.

dont mind me lads bad day i may go for a spin and chill the fuck out insurance nearly up any one recommend a good insurance company to give money to !!!!!

good bootmount and water/meth injection.

When my new nozzle kit arrives this week I will be injecting water/meth both pre-turbo and pre TB.
