Intercooler or bonnet scoop or both?

[ssray]

Am i right in thinking that you should have the biggest intercooler you can fit? as this will act as a plenum chamber and a small one may restrict air flow which would defeat the object?

on the australian site some kind hearted soul has done a flow test on loads of different intercoolers. very useful..

which site mate?

aha - thanks muchly... wonder if you can squeeze one in without a body lift
Anyone fitted a dump valve thats not OEM? Read a while back some were thinking of it but was just wondering if anyone did bother...

keep looking on the aussie site.. some of them colonials get quite adventurous with the tuning....

Didnt know you could beat box mate

Loads of intercoolers on ebay - Audi S3 anyone? MR2's Supras Imprezas all look pretty good...
i gott say though I love the original Impreza bonnet scoops

[Vagrant No2]

the standard intercooler is mounted on top of the engine, so the scoop flows the air through it...
aftermarket ic's are usually mounted below the rad so you don't need a scoop.

vented bonnets for engine cooling usually have rearward facing louvres (like on the ford cosworth/renault GT turbo) these increase the airflow through the engine bay.

on the highly tuned "hot hatches" you will usually see the front bumper cut away to expose the larger intercooler.

I don't believe it ! Matt got something correct and intelligent .
Forward facing bonnet vents 'ram' feed air through a top mounted intercooler . But rearward facing vents to to help draw ait from the engine bay .
Your average car vents the engine bay under the car but these Surfs have so much packed under the bonnet there is not much room for air flow .If you mount the vent forward it could make things worse (IN MY OPINION) as the air could 'stall' in the engine bay . The rearward facing vent would help the air escape in the direction of travel and hopefully increase air through the rad and engine bay . May also defrost your screen in winter

What bonnet scoops were made for, nice.

p.s. you really need your speakers on for this.

the info and know-how being shared here is really really helpful!

thanks so so much!


that is why hot-rodders have their hood scoops opening facing towards the windshield for the purpose of not creating turbulence against the radiator fan.
this way ALL the hot air is pushed out in one direction out of the engine bay instead of it circling around it.

now i understand even further.


no wonder my friends who have no bonnets installed, lifted their hoods, the area facing towards the driver.
