Is there such a thing as a TASTEFUL targa top air scoop??

Posted by: 76-914 Feb 12 2015, 04:05 PM

I saw a nice one on a Boxster that precissionchassis built. It's on here some where. I know; thx for nutin.

I got your 6





All that work to feed this, yep air to air intercooler

I saw a Honda Accord this morning with a scoop on the roof.

and this one

Reminds me of a Fiero with an Indy Scoop, okay maybe that one looks better.

FugUgly.

Back to the original question. Did U mean air scoop for the cabin or motor?

Posted by: Mueller Feb 12 2015, 04:59 PM

He said tasteful.... I see that Boxster above and visions of mating season for dolphins pops in my head

air for the engine or intercooler

Posted by: Mugs914 Feb 12 2015, 06:29 PM

Probably not...

But that being said, here are a couple that we have done:

This one feeds air to the cooling fan on a six. It sits about four inches closer to the firewall that a stock six and we wanted to make sure it got plenty of air.


This one feeds air to the intake and fan. I am vintage (as opposed to old) and remember when Formula 5000, F-1 and Can Am cars had high air boxes like this, so while it certainly isn't for everyone, I like the look. This is actually a prototype for a scoop that will feed the intercooler on a turbo race car.


So no, tasteful is right out...

Cheers!

^^^ Hey, I think I've seen that car somewhere.

Posted by: marksteinhilber Feb 12 2015, 10:48 PM

Sorry, but I just saw the huge whale tail too and the two together makes me think Boing 727, just saying '. And I'm not a pilot, unless you consider a 914 is always just taxiing!

Posted by: Larmo63 Feb 12 2015, 10:57 PM

Nothing on this thread looks anywhere close to good, or tasteful. IMHO

Posted by: ripper911 Feb 13 2015, 07:06 AM

What about running a channel from the frunk through the cabin, or center tunnel, and into the engine bay?

Posted by: barefoot Feb 13 2015, 07:41 AM

I've seen images somewhere of a race 914 with a huge duct there the cabin.

Posted by: JmuRiz Feb 13 2015, 09:35 AM

I remember that too, but that was to get cooling air to a 914/4 race car engine bay, directly into the cooling fan.

I do remember LONG ago (like when I was looking at chuxter's site) someone made a 1/2 circle plexi piece and mounted it to the trailing edge of their targa top. It was to divert air from just above the targa top - down into the engine cover grill. I can't find a picture of it though.

Posted by: 914forme Feb 13 2015, 10:32 AM

You mean like these

Posted by: Dave_Darling Feb 13 2015, 11:29 AM

Sort of like those. But the more "traditional" setup is to run a large piece of HVAC ducting (approximating the diameter of the fan) from the trunk back through the cabin, through the firewall, and terminating at the fan inlet. The air was picked up from the headlight holes--which was due to some racing regs intended for Little Brit Cars that allowed cooling air to be ducted from the headlight openings.

Jmu, I think John Rogers had a setup like what you describe across the back of his roof. I don't recall seeing pictures of it, but he described it in at least a couple of threads on the Bird Board.

Racer Chris had one of the HVAC ducts running from front to back. I'm sure he'll dig up a picture for you guys. I remember it looking really cool!

Posted by: d914 Feb 13 2015, 11:43 AM

If its for an intercooler, wouldn't be more efficient to go to an air/water intercooler..
the actual "radiator" could be feed off of ducting from the rockers.. They are typically smaller,,, plenty of places to hide..

Ive seen quite a few setups similar to racer chris's and a roof scoop w lexan pieces feeding the engine..So you could see through it!!

Posted by: JmuRiz Feb 13 2015, 02:33 PM

Found it, from 2002...has it been 13 years already...
Painted the same black as the top would hide it quite well with getting the benefit of added cooling air.

I carved some scoops out of foam that I was going to cover in CF and mount them on the sail panel. I havent finished them yet.

Just to see if they would work I taped some plastic irrigation pipe to the sail panels and drove around. It worked suprisingly well. Looking at megasquirt readings as I drove my IAT readings would drop by 10*.

The CHT readings dropped by 5-10* also

Posted by: 914GTSTI Feb 14 2015, 11:36 AM

You got me FOTFL . That is some tasteful idea !

Posted by: mgp4591 Feb 14 2015, 01:25 PM

How about something like that underneath to funnel the air up into the engine compartment? The airfoil in the pic not only cools the engine it also fills in the negative air pressure area behind the passenger compartment letting it slip thru the air better.

Posted by: Dave_Darling Feb 14 2015, 03:25 PM

Counterproductive. The top of the engine bay is where the cooling air comes from, and it exits under the car. The top and bottom should be separated by the engine tin. Ducting more air underneath the engine will result in less pressure differential across the cooling fins, so less air flow--so less cooling!

There are flaps under the front of the engine bay on later cars; they produce a slightly lower pressure under the car to help pull the air through the engine a little easier to help cooling.

Ah, I see... I'm not thinking air cooled enough... Could work for a water cooled conversion for taking heat off the exhaust tho.

Posted by: Maltese Falcon Feb 15 2015, 12:33 AM

Harold von K / 9146 turbo.
He used 2 of these air scoops from an open-wheel race car of the '70s era.
It was exceptionally fast, sounded wicked, sticky and threw flames, but the scoops looked like something at the harbor
The air scoops did work well for engine+intercooler chores.
After this car retired its club racing turbo duties...it was returned to its first livery: an original Kremer Bros. built+raced 9146gt .

The well-known black SCCA Kirby 914 had a similar cooling air arrangement. I saw it many years ago when the SCCA Runoffs were held at Road Atlanta. (As I said, many years ago!) It had air intakes at each headlight opening, which were ducted in the front trunk in a Y-configuration, then combined to form a single round duct through the cockpit to the engine bay. The type-4 engine cooling fan had been stripped of its blades, so the cooling air delivered must have been adequate.

I always thought these scoops like a 904 would work. But if done wrong, the car would rust even faster

Posted by: Maltese Falcon Feb 15 2015, 09:48 AM

This simple air scoop was made from a cabin defroster duct ,some flex tubing and a bracket. Just used on track days to direct some cold air on to the intercooler.
