pompei Posted December 28, 2015 Share Posted December 28, 2015 Why have them? I'm looking at you Mr Impreza and I can see you too, Mr Kia Sedona. Show off? My Saab 9-5 never needed one nor do the myriad turbo diesels out there. Are they really necessary? Discuss. Link to comment Share on other sites More sharing options...
garbaldy Posted December 28, 2015 Share Posted December 28, 2015 When your vehicle runs an intercooler then they work more efficiently with cool air hence the bonnet scoop, if they can be put elsewhere they can get cool air through the grill but some engine bays are well cramped so easier and cheeper to slap them on top of the engine and cut a hole in the bonnet Link to comment Share on other sites More sharing options...
lincolndanny Posted December 28, 2015 Share Posted December 28, 2015 Technically some Imprezas did as the intercooler is on top of the engine. Brilliant idea that"Hey lets put this cooler above something hot" Link to comment Share on other sites More sharing options...
LessThanEqual Posted December 28, 2015 Share Posted December 28, 2015 Imprezas have a top mount intercooler. Link to comment Share on other sites More sharing options...
willswitchengage Posted December 28, 2015 Share Posted December 28, 2015 Old engines - air intakes directly above the carbs/supercharger.No longer work with cars with complicated airbox systems. Some cars have them for the intercooler which obviously makes sense, but that's just a packaging issue that they're not in front of the radiator. Doesn't the BINI have a fake one?

skattrd Posted December 28, 2015 Share Posted December 28, 2015 The way I see it is if you have a top mount intercooler then you need an appropriate scoop with ducting. If you don't have a TMIC you don't need a bonnet scoop.TMIC with no scoop = not great cold air supply for IC, unless there is serious ducting in place.Bonnet scoop and no IC below = knob or engine runs too warm Link to comment Share on other sites More sharing options...
Lacquer Peel Posted December 28, 2015 Share Posted December 28, 2015 Some Peugeots and Citroens used TMICs without a bonnet scoop, albeit in a relatively low state of tune.I can see why a 300bhp Impreza with a TMIC needs all the air it can get, and a 90bhp Peugeot can make do with a grille scoop.

xtriple Posted December 28, 2015 Share Posted December 28, 2015 There's a big green thing parked outside with an intercooler under the engine cover on top of the engine. No scoop and adds a whole 25hp so wildly efficient! Link to comment Share on other sites More sharing options...
stephen01 Posted December 28, 2015 Share Posted December 28, 2015 I need a scoop for the panda mainly to stop it filling the air filter with water, but at 18 quid, I'm out. Link to comment Share on other sites More sharing options...

garbaldy Posted December 28, 2015 Share Posted December 28, 2015 The mad one eyed look is not for the intercooler though it's the air intake,That's the intercooler in the huge opening in the bumper hence no bonnet scoop, Link to comment Share on other sites More sharing options...

MarvinsMom Posted December 28, 2015 Share Posted December 28, 2015 no surely the Rover P6 NADA has the most number of scoops on one bonnet.... SWMBO has a suzi vitara, all throbbin' 1.6 litres and 69 bhp of it... that has a scoop too, though i think that will add absolutely nothing to the performance of the vehicle.it has nothing to add to the car other than it look good* apparently.

John F Posted December 29, 2015 Share Posted December 29, 2015 My Maserati has venturi-style vents in the bonnet, but that's for letting hot air out rather than ramming cold air in. Link to comment Share on other sites More sharing options...

KruJoe Posted December 29, 2015 Share Posted December 29, 2015 Some motors were fitted with scoops for the heater, old Pandas, I'm talking about you, and Rover Metros too I think. Didn't they have two, but one was a fake? Link to comment Share on other sites More sharing options...

fordperv Posted December 29, 2015 Share Posted December 29, 2015 I presume on the 19 16v it was just to lower the temperature of the engine bay, iirc the exhaust manifold was on the rear of the engine next to the bulkhead Link to comment Share on other sites More sharing options...
