I'm just having an FMIC fitted on my MY96 turbo and I want to reverse the main scoop to draw air out of the engine bay, as I no longer need it to feed the top mount.

My mini bonnet scoops at the front should draw enough cold air in.

Obviously it's not just a matter of turning it round as it widens at the front, so the hole is the wrong shape when reversed.

Has anyone done this?

If so, how did you do it? Does someone make molded reverse scoops?

Any help/advice appreciated

Cheers

Seen this done on a sccoby on here, it was a new scoop specially made for that bodykit he had on.
Sorry i don`t know much more but to the point it positivly looked utter sh*te with it the other way and every one on the post said the same, just keep it the way it is they look the bis anyway.

Reversing the scoop is a common thing to do in Japan when it comes to a front mount ic. Do-Luck do a scoop that can be mounted in both directions, otherwise, you can go for a complete new bonnet, like the Cusco or Zero/Sports one which is specially made for front mount intercoolers.

If you need futher information, mail me offline. Oh and don't listen to people that think it looks shi*te, they shouldn't have bought an Impreza in the first place, a TT would also be fine for them......

 

The air movement that the scoop would create pointing forwards should mean there's some fast (well, ish) moving air down the back of the engine with the intercooler gone. This movement should help suck air (well, a little ) from the front of the engine bay. And so might even be better than revesing the scoop

 

how about fitting a sport bonnet and getting your own scoopage done to suit?

 

I saw a black one in a mag from Japan that had the standard scoop reversed and it looked awesome.

Sport bonnet is a good idea but I've just shelled out for an Aluminium one and a respray, so that's a no-no.

Have you read this? If seen this debate a few times now.

I remember someone saying, i think it was Bob Rawle, that leaving it where it is provides a nice blast of cool air onto around the turbo piping etc. Personally, I prefer it the way it is.

OK this isn't gonna be much help to anyone but I'm sure someone on here had completed some tests and proved that reversing it was no good at all.

Doesn't the scoop help to reduce under bonnet temps by pushing air over and around the turbo and out the underneath of the engine bay?

Someone had however fitted an evo type scoop in place of the original scoop and this had proved to be very successful.

 

Rich,

I deal with this sort of thing fair bit and believe it is best the way it is. With it back to front, you would need some air force from somewhere else to force the air up and out of the scoop. With it the right way, the overall circulaton will be better, as there will be incoming cooling air into the engine bay. As the air is no longer going into the top, IC it is all directed to the engine bay, so some good cooling.

It may be worth while piping some of the scoop air to the Cone? I know you have small scoops too, so may be of no benefit.

Or just make a grill and surround to go in the scoop hole, that way air can flow though and out the top.

less hassle than reversing a scoop

 

Cheers guys,

Thanks for the replies.

Looks like I may be better off leaving it then. Not sure I like the Evo style vent idea (would feel like a Scooby traitor)

Keep the ideas coming anyway.

Cheers

torque developments in barking essex were doing a lot of work on a white scooby that had a reversed scoope, try calling them & asking if they can help, or leave it where it is & stick an oil cooler where the tmic was

 

How much would you want to sell the bonet u've got on atm for? mail me ofline if you like

 

What about the Zero/Sports one?

 

I did some fabrication work for an Irish tarmac impreza that had been running with the scoop the wrong way round, The driver didn't like it because when his engine let go he got an immediate screen full of oil and as a consequence had a small off. So we put his scoop back to its normal way round and made some ducting that directed the air around the back of the engine and onto the turbo. Not sure whether it actually cooled the turbo or not but we did get a lower temp in the FMIC, presumably from pulling more air from the front of the engine through and over the turbo and out the back. I may be able to get some pics if you are intersed.

 

Hi Rich,
When I fitted my FMIC I intended to get rid of my scoop to improve aerodynamics. Did a lot of testing using max/min thermometer at various positions in the engine bay and monitoring the throttle body charge temp.
I was very surprised by what I found.
I totally removed the scoop, partly and fully blanked the resulting hole, replaced the scoop and experimented further with partial scoop blanking and channeling of the air and so on.
Your bonnet is different in that you already have two smaller scoops at the front but for my car it was VERY clear that the scoop should remain in position along with the backplate on the innerside of the bonnet. The existing grills remain with blanking plates in position. A small fairing encourages a bigger proportion of the air to flow in the direction of the turbo and d/p. This I think is important.
My conclusion was that the air comes in to the front of the car, over the engine and down the transmission tunnel carrying away heat from the turbo etc. I do not think there is any merit in altering the air flow beyond what I have done for my car now the TMIC is removed.

 

Thanks for all the replies guys.

Think it's best to leave it as it is.

Cheers

Rich

 

That Zero/Sports one is loverly - oh - I am dribbling at the thought...
