What kind of interest is there in a custom fabricated intake bonnet? It would be welded aluminum 6" cylinder with either a single 3", single 4" or dual 3" snorkels. It would be supercharger ready but not tested. Assuming you do the mechanics of materials it should be able to handle ~20psi with the proper gasket.
There are plastic pieces selling on ebay for like $50 but they aren't for boast applications and they're single snorkel only. They do come with an air cleaner and mine wouldn't unless I could get enough people to order. I'll have a picture soon but it's nothing fancy. The cost of a single 3" snorkel will be like $50, single 4" $60, and dual 3" being $75. This is only trying to get a feel for the market.
Cold air, cone air filters, ram air, power adder ready, super low hood clearance (you tell me the height you want), and cheaper than you'll find them anywhere else.
Please don't say you're interested. I need at least 4 definate people within a couple few weeks before I get the stock.

JP, do you think with your bonnet you would be able to use a stock hood with an RPM Airgap intake. If you were to put two or more hold down screws around the bottom outside lip of the bonnet you could do away with the center screw and wingnut. Just an idea.

that sounds pretty cool, i'd at least be interested in getting a better idea of what you're talking about.

on a related note, i wonder why tbi and carb users don't adapt tpi air intake setups. it seems like it'd be especially easy on a camaro:

1. use the camaro over-the-radiator plastic piece (sorry, i don't know what it's called)

2. take a stock aircleaner, cut off the snorkel and weld or pop rivet in a piece of sheet metal to block the opening.

3. get a piece of 3 3/4" exhaust tubing (i believe that's the opening size on the tpi throttle body. if not, use whatever tubing is the same size).

a) compress one end of the tubing so it can be cut and welded to the center of the aircleaner housing.

b) cut the piece of tubing to length so that the end closest to the radiator when the aircleaner is installed on the car is in the same position as the flange on the throttle body of a tpi car.

c) compress the end of the tubing closest to the radiator so it emulates the intake flange on a tpi throttle body

d) use the stock tbi connector hose to hook it up.

is there a reason this wouldn't work?

Sounds like a lot of extra work and money to adapt an already restrictive TPI "snorkel" intake. Those things don't flow very well, just use what I'm making and duct the air cleaner over to the side for cold air.

It'll look like that only welded aluminum and your option for the snorkel size/number. Think of it as an alternative to the open element and the other options on ebay that are just as expensive but made from cheap plastic.

where would you draw air from? where would the filter go?

slp makes cold air boxes for tpi cars. i'd think your bonnet might work with one of these pretty well, and it'd resolve the air cleaner question.

has anyone seen one of these slp units on a car? i thought i read they drew air from the fenderwells, but i can't figure out where.

With the aluminum hat you could put the filter anywhere you want. The stock direction is probably best. Just relocate the charcal canister to below and put the filter in that corner.
It doesn't sound like anybody is interested so I'll just make a few and get pictures. Oh well.

I'm waiting for pics.

I'm sure you are. Tomorrow I hope to have a dual 3" done. Time will tell seeing that not to many people seem interested and I've got a busy week ahead of me.

Hey sounds like a great idea i need to do somethin about underhood heat i know it's worth a tenh or two in my monte. I did a test a while back where i took a cheapy outside temp guage and ran the probe in my air cleaner. The only place it wouldn't peg out at 140 was runnin 80 on the highway even then it ran at 135, so if your runnin an open element on your tbi or carb your suckin in some mighty hot air. I may be interested in your bonnet depending on how it turns out. I would like to make my own but some times the calculus gods don't allow me enough time to do so.

JPrevost

You want the intake manifold warm and the air cold. Dryflow intakes are more senstative to intake air temp than wet. The fuel being atomized really cools down the air a LOT. So don't think that your engine is taking in hot air, it's definatly warm but the IAT is just to give you a good idea.
The dual snorkel will be really cool but you'll need to get a couple of those 3" K&N style filers they sell on ebay for like $15 a piece. Or get a single 4" or single 3", it's up to you.

Im really looking forward to see how it turn's out

I think I would go with the single 4" in my application it would just be easyer to route. I already have a 14x3 k&n so i might try to make a box to seal it off that way i can just run some cool air into my box using some flexible hosing....Which brings me to another question where can i get some good flexible hosing that won't melt or look cheezy like dryer hose does.

Flexible Hose -
check out AutoZone or Advance - no pics online, but they have hose from MOTORMITE that is similar to dryer hose, but stronger, various sizes, comes square or round, and is black in color - and specifically made for air intake.

I need to go get some 3" aluminum tubing and sheet metal to finish up the first batch. They're all dual 3" (3 made so far). The 4" version would require the use of the mill and the indexing vice. Those things take a lot of time. Once you see the size of a 3" you'll see why I think a single 3" is MORE than pleny for any Lo3 <300hp. I'll be trying them all out on my maro.
