Just fitted a new Airtec rad , also got a used Airtec intercooler that's had twin fans fitted. I've read that the fans are better fit between the intercooler onto the rad. Call me anal but t don't want to bend the fins on the rad when the intercooler has already had this done to fit fans. How much will it effect cooling if I go onto the intercooler. Running standard at mo but going to fit a turbo systems chipped ecu so not sure what bhp I'll get but been told 180 / 190 ish is expected. Advise appreciated please.

 

Also once I fit the ecu , I'm going to need setting up where do you recommend ? I'm in the northeast.

 

I'd say it makes a massive difference. In my opinion the intercooler doesn't need fans as the points in time where you want to cool the charge air is when you're on boost - motiring along at good speed with good airflow on the front of the cooler.

The important times you'll want to cool your water is when you're sat in traffic with no air flow at all and if your fans are pointlessly blowing air through the cooler when its not needed all your rad is going to get is any moving air that comes out the other side, which won't be much.

I'm sure other people will disagree but for me the fans need to be on the rad or you'll forever be wathing the coolant temps and having issues especially suck in queues in the summer, i.e. on the way into every show, ever.

 

I believe it's all in the fitment of the rad and intercooler.

There is a benefit to charge temps to putting the fans between the two as there's more intercooler surface exposed for cooling.

As for coolant temps, as long as the intercooler and rad are butted up nice, tight and square you will be fine. Air will take the path of least resistance, so if you have a gap, less air will flow through the rad, more around the rad.

If you put the fans on the rad, it still has to draw warm air through the itercooler anyway to cool the rad.

I have my fans fitted to my Airtec intercooler which is tight against the Airtec rad. I rarely get above N on the temp gauge when stood still in traffic. Operating temps generally around the R.

Not disagreeing with mannion just offering a diferent opinion.

Do guys still think a stainless rad is a better choice over std copper rad?

 

My fans are on my rad I have airtec rad and cooler

 

Fans are on my airtec cooler,does not over heat in traffic at all ,even after a couple of hours

 

I'd put the fans in between the rad and cooler that is the better way than having them on the front of the cooler.

Got mine on the IC and seal fitted to the rad with draft sponge, like this all the air from the fans is forced through the "standard" rad, instead of just blowing out of the sides / gap due to the air being turbulent after the IC, The amount of air that comes through the rad from the fans is amazing and trail fitted with out the seal before hand and found little to no air flow. My bumper is a standard 90 spec no cutting etc, the only mod was the blank in the lower mouth was removed as the bumper is 3i not 90spec turbo.
Temp wise even when the weather was warmer at 20-50mph it ran at the top of the "R" and at 50-70mph it runs at the bottom of the "R". In traffic on a standard fan switch the fans cut in at near the top of the "O" and off at bottom of the "O" which is exactly the same as it did with the old EFi 3i motor.

I did it this way as I didn't want to cut the bumper.

I have fitted a turbo bonnet recently which helps with removing the engine bay heat.
