Can anyone please tell me which is the best option? A friend of mine has recommended that I get a chargecooler for my S2 as he says that there the best option?, my uncle has got a lotus turbo with a chargcooler on it and I know it works very well, but looking around I,ve not seen many rs turbos with chargecoolers on?

Any info would be appreciated as I don't want to wast my money

Thanks in advance,

Ant.

 

theres your answer

 

depends what you use the car for. unless its for 1/4 mile sprints then im pretty sure that a big intercooler will suit your needs!

 

The answer is price. Chargecooler is considered the next step after a larger intercooler. If you have the money, a chargecooler kit will be better. But a larger intercooler is more value for money.

 

i've got a chargecooler on mine. works well to be honest.i've just bought a act gauge so i'll let you know how well soon i guess the only downside ( could be an upside for some ) is that it's not as obvious as a large intercooler i.e can't see it very well,and i guess they are quite expensive.

pics below, you'll see it's not very 'in yer face' like a mahooosive i/c

 

Well, what would you like? Good ACT:s undependant of speed? Less needed volume to fill up when spooling up? Then go for a charge cooler, presuming there has been some intelligence involved when designing the system.

 

Sorry to but in

But whats the difference between the two? How does a chargecooler work as oppose an intercooler? same principle?

Thanks

intercooler cools the charge air by havinf air flow over what is princably a radiator! the larger the surface area the better the cooling (aprently) ie more cold ait that hits the intercooler (front mount on rst's) the better and cooler the charge air will be!

A chargecooler works by cooling the charge air by water! so it doesnt matter if your sat in traffic you shouldnt get any heat soak! (but theres mix opionins(sp) on this!!

HTH!

 

Bud weis...either im tripping out or your pics have movinh silver specs ! like its been added by photoshop! might just be me tripping, got one hell of a cold!...

 

think your trippin matey

 

i agree with what james said but..........

you wont suffer heatsoak with a chargecooler when sat in traffic - they will keep ACT's lower than an intercooler. but once you have taken it for a blast the water will heat up and make cooling less efficient. next time you are stood in traffic the benefits of the chargecooler will go out the window due to heatsoak!

 

James, ur tripping

 

the water is kept cool by the radiator sat at the front of the car where the intercooler usually is. the water jacket on mine is just behind by the gearbox.the water is continuously pumped around this radiator and water jacket so why would it suffer heat soak? the cool air as you drive keeps the charge air inside the system cold so when you come to the next lights, you'll be just as cool as an i/c, if not cooler.the water in this system is not connected to the car's engine coolant in any way, it's a seperate system altogether.

 

The larger radiator you have to cool the water the more efficent the chargecooler will be. Water can hold many many times more heat than air. There is limited room for a intercooler on the RST so a chargecooler solution is more effecient since it doesn't need so much space. The chargecooler is efficent even with a small system. The radiator can also be fitted with a fan. Escort Cosworth had a chargecooler, so did the Lotus Esprit.

My plan is to convert the original intercooler to a chargecooler with some soldering or welding. A radiator (heater core size) and a pump is also needed.

 

i have a chargecooler and it works brilliant no overheating or detonation runs nicely on 18psi and thats on a standard bottom end

 

charge coolers were good in the early days when the cars were new and nobody wanted to make major mods to the car to fit big front mount intercoolers.. however, the cars are generally making much more power than they were 10 years ago and the charge coolers just can not reject the heat at the same rate that the turbo makes it.The net result is the water gradually running hotter and hotter.The other problem (apart from cost) is pump reliability- once the pump stops you are in serious danger of detonating the engine.
There also have been many problems with chargecoolers leaking water on high boost cars.
Lotus used a charge cooler on the Esprit simply because it is a mid-engined car and it was very inconvenient to use an air to air cooler...
simplicity is always best in our opinion.

 

a good technical answer i would like to have written myself!

its personal opinion - but i would always prefer to use an intercooler myself!

 

Intelligence..of course, I designed that one (pace)!!!!!
mind you it was about twelve years ago-lots of things have changed since then

 

There is limited room on a RST and the airflow isn't the best, so water will be the best heat remover. Water can store alot more heat than air.

 

indeed..provided the water system can reject that stored heat!
The later generation front mount intercoolers are far better than charge coolers- especially for high boost applications.

 

A radiator is uasually easier to fit because of it's smaller size, but the chargecooler will get more efficent with the size of the radiator increasing. An intercooler setup requires less maintnance and care so a chargecooler is recommendable if your are an enthusiast, like me.

 

Ive got a Charge Cooler (Pace) on a stage 2 Escort s2, and the temps are low, ive never had a problem, and i always push the car hard, im going for a Stage 3 set up, and will be using the Charge Cooler.

PRO ALLOY MOTORSPORT, how much would a bigger radiator for it be, as it is a bit small???? how bout a monster rad that looks like a intercooler???

 

If you are going to do that you might just as well get an intercooler, if the pre -rad was to be made to look like an intercooler you would need to use an intercooler core..you would also need to change the fan for something slimmer so we could fit the big cooler in.
The next thing you would need to change after the pre-rad would be the water tank-making it bigger.

 

wayne/proalloy any chance of a pre crimbo discount price on ya large front mount!?

 

yes bud.. they are £400.00 inc vat..untill christmas...
