While i'm hunting the classifieds for a 3R, I came accross a 2.5 car on ebay that has added 2 radiator fans to his intercooler, my first thought is that it was a silly idea, but I guess if your stuck in traffic alot, it would help intake temps, but then in traffic you wouldnt get any benefit as you cant use the dense air and put your foot down

So is it as daft an idea as it appears, or does it have merrit ?

He's also removed the rear spoiler which looks good, although I wouldnt do it.

Image can be seen on the fleabay advert - I am unassociated with this car and do not wish to promote the ad, but I couldnt find another way of adding the image of the engine bay

My previous car had water sprays on the intercooler, a lot of work was done to test the system and the end result was that from one extreme to the other, you could gain 2hp.

The consensus was that removing the pump and distilled water container made a better improvement in weight saving !! then if you used the space created to duct cold air to the intake filter, it was far more useful than the water spray.

However, I left mine in place, preferring originality over the extra debatable hp

Hi folks

I have owned my 3R for 3 years now and cringe at my original post above !
However, I have not added fans as yet on the IC, I haven't come across a need. I'm running the original IC which gets hot, but that's its job.

Still thinking a "suck" fan on the back of the IC might help and would hinder airflow less. But as I say, I may be trying to fix a problem that doesn't exist.......... jury is still out

Hi Rob
Congrats on the car.
I recommend you do some searches here but also join the Fbook group. This subject is covered in detail in the past and you'll find loads of useful info

I havnt had a 2.5, but I think 370hp is about the best compromise between work costs and returns. Check out people who have had problems at 400hp with a 2.5 in the past.. I may be wrong.

Have fun researching
