Front bumper air scoop?
 

Does anyone know if there is a manufacturer that makes a cold air scoop like this one? I think this instead of the snorkel would solve a lot of people's problems with the snorkel.:thumbup:

ive been wanting one for a while. im not a 100% sure but that scope for the 350 i heard isnt vehicle specific. i could be wrong, regardless i want one

I haven't seen one yet, but you can always break out the dremel, a utility knife and some bondo and DIY...:D

exactly!

I was thinking of putting one were the fog lights would go.

@JDMenrique Do it!

Interesting idea, thanks for the post!

I'm not sure either, I'd be worried about the curvature of the bumper matching the curvature of the scoop.

or put foglights in like i did :D

Great idea mate, very interesting especially for those of us with the Injen intake

*Patent pending*

I'm sure doggy could fab something up if you ask nicely and he has time.

were did you get the fog lights. Are they factory or aftermarket? Also do you have any pics?

That's great if you don't mind risking hydro induction. A high mount intake port almost eliminates this completely and it's a short /direct air inflow path.

I've actually seen that port in a 350Z. I too believe it may not be car specific.

Good point! After seeing the fog lights I'm getting some! I'll put the intake some ware safer. But my car stays in on most bad days!

There is no point in this, I cut a bigger hole right where the perforation is at the beginning of the nose, I can hear the intake(stock) sucking so much harder now. An aftermarket hole is not needed imo.

its not about noise...
this mod is to lower the air temp at the intake.
somebody posted a log of intake temps between an afe and air raid intake, something like 15 degrees difference at the maf.
this would allow a much cooler air charge to reach the snorkle or filter depending on the intake you are running.

This.

This is not necessary if you are using the snorkel to funnel air into the intake (be it stock or aftermarket).

There is no problem with the stock snorkel or its location.

you can't tell me that this won't lower intake temps. You really believe the stock s orkle laying in front of the radiator/ on top of the bumper beam is pulling the coolest intake charge possible?????:confused0068:

Yes it will lower the intake temp, But it will also makes the car run like crap.

more info?
the maf should calculate for this.

During the conditions you would WANT lower intake temps (ie moving) the heat from the radiator does not enter the snorkel because it is blown back into the engine bay. The only air it would be inhaling is cool air from the front air dam. Think about it please.

the snorkle is covered by the nose cone the bumper creates.
The radiant heat from the cooling system/engine will have raised the temp of the snorkle and the intake plumbing. Thus heating up the intake charge.

LOL, the air is cold in front of the radiator, not so much behind it.

If an AFE has a delta of about 10 degrees above ambient and doesn't even extend into the bumper (but still sucks air from it), then there isn't much to be gained, temp wise, from this.

here is the info i was talking about..
air raid uses the stock snorkle i beleive.

Those tests were done without the snorkel. The snorkel has been proven to lose around 2-3whp on average. Airaid even suggests removing it for the most "power".

so if the snorkle looses power, isnt that related to temps more than likely.
honestly the stock system flows more than enough air or they wouldnt have designed it. so i am going back to the temps are the issue stance on this one.

Restriction and/or flow dynamics are the issue(s). I've done a few dynos (hood open to negate temp difference) between stock with snorkel and stock without snorkel. There was a consistent gain over 3 consecutive pulls without the snorkel.

the hood open thing has been discussed also. alot of people think that opening the hood has something to do with temp also.
I havent dyno'd on this car so i dont know, but i have built a lot of "track cars" over the years from dirt track to "street able" and we have always found temps to be the biggest issue with intakes.

I've been one of the biggest advocates of hood placement on dynos. Intakes like the Injen get artificially (sometimes drastically) inflated numbers when dynoed with the hood open.

While temps do play a part in the power generated, I don't think you're going to see any considerable gains in cutting up your bumper to pull direct air over an intake like VMS, FA20, or AFE. Plus, you also introduce a dangerous factor; water.

The fact is most intakes make their power on how they lean the car out. That has much more of an impact on the power output, than dropping the temperature difference down 2-4 degrees. All of this becomes moot, once a car is tuned to run stable AFR on whatever intake is installed.

I have played the water game before on my starion.... A 20psi vacuum cleaner will eat some water...:bonk:
I am waiting on my fa20 cai... I haven't decided who's tune yet.
I hate the bolt on and get lean manufacturing process that allows products to claim power increases.

Working on that right now. Using the foglight bezels on both sides and then joining in front where the current snorkel is. Going into a sealed box with a cone filter. When I'm finished I will release some pictures. I thought about installing an LED or two in each pipe and connect them to the headlights. That way at night when you turned on your headlights you would see a blue glow in the pipe opening.

That sounds assume!!!! Can't wait to see some pics.

Any pics?

Air turbulence, that is all I know.

how would it create turbulence inside the intake... that makes no sense. the filter and box will still exist.

Just to add what 2forme posted earlier, I did some testing a while back on my stock intake but K&N filter with AVO pipe. This was done using ECUtek BTW. Ambient temps were 3/4 degrees C:

That's from multiple pulls, multiple gears from 30-90mph.

My point of view on this is that an intake scoop wont make lower intake temps, but it may help them drop faster! But ultimately you have to work out will the cost benefit. I don't think the stock snorkel is that restrictive at all. I was at a tuners the other week and he dyno'd a mate's car with hood open and closed, the only reason he did that was to see how good the intake was as it shouldn't make any difference. The difference was 0.2hp (better with the hood open)!

I'm about 6 weeks out. Waiting for the foglight bezels. In my opinion you really cant dyno something like this accurately. Maybe you can if you had a wind tunnel and could setup a dyno in there and had a computer system match the wind speed to the dyno speed.

When it comes to the stock snorkel I believe that Toyobaru had to make a cost effective way to get air into the engine. I'm glad it was outside the engine bay but the opening is extremely small and they put resonators on it to quiet it down. Then they installed a tube to the cabin to give you sound. I felt like the motor wanted to explode the closer I got to the redline. I went with an Injen intake and found it to be a vast improvement on not only the performance level but also the sound factor when the sound generator was deleted. For S & G's I installed a Tornado right after the MAF and noticed another improvement in the mpg's. I can run an entire tank of fuel in the city and still be in the 30's. Saying tHat doesn't sound too impressive but you have to understand you are driving a sports car and not your grandma's Buick; you are going to stomp that thingy on the right to the floor a few times during that tank.

So this is my design. I'm going to keep the intake tube and filter from the Injen and improve it in my opinion by making a completely new box that is 100% sealed and have both intake tubes run from the foglight bezels to a two-into-one junction.........and enjoy! All of us know that it will do nothing on the bottom end but should BE nice up top. And hey, if it doesn't do what I want I'm out 400-500 bucks and about a weeks worth of time. If it does, I have a great product that can be sold to other enthusiasts.
