See post #118 on page 3 of this thread. I didn't neck down the ram-air boxes. They are the same dimensions as the lower filter box. I used 3M SMC two part epoxy. It takes a specific gun and mixing tube to dispense it. I got the ABS strips and ABS sheets in various thicknesses from a local plastic supplier. I also use a craftsman air-saw with a blade made for wood/plastic to cut the bottoms off. It doesn't gum up the blade or clump the plastic like a dremel tool would.

I hope that helps...

For those of you trying to maximize air flow:
http://www.funkz.net/firebird/firebirdmod22.htm

Instructions on how to modify your throttle body, it should give a small increase in flow, but more notably improved throttle response, I did it myself though I still need to finish sanding the inside to smooth it out.
Unfortunately I can't say how much of a difference it will make since I've never driven my Camaro (bought with non running engine) also rebuilding the engine to not even remotely resemble stock output levels...

1bad91Z

iTrader: (1)

Well, thanks for posting the info, but most of the info in this thread is in reference to maximizing air-flow to the throttle body (V8 TPI throttle bodies).... , not the throttle body itself.

Project 3.4 Camaro

Yeah, but if someone is going to that kind of lengths to make the airbox flow better, I imagine they would want to do this mod as well if they haven't, plus its cheap and relatively easy, albeit rather time consuming, all you really need is a dremel with bits and some sandpaper, and patience. But I think its something a lot of people don't even think of, and all the airflow to the throttlebody in the world won't matter if it cant get past.

1bad91Z

iTrader: (1)

Although I do see your point, most people aren't concerned with the air-flow of a V6 throttle-body. Also keep in mind that the stock V8 TPI air-box is plenty adequate for even a modded naturally aspirated V6.

I'm not scolding or ragging on you in the least, so don't think that. But, this thread is about a high-flow air box that would normally be used to feed some form of a tuned-port injected V8 Camaro (beings it wont fit on a Firebird).

This summer, I may be fabricating a few more lids to be available for purchase (time permitting will limit quantities), so if anyone would like one made, let me know to get your name on the list.

On a side note, I read that a member here on TGO is working on modding a bird for a camaro style tpi lid. Should be interesting!

There are several pictures of lids that I have made for people here on this thread. Look through all the pages on this thread and you'll see contruction of one, installed pics, and others that I have made for people, along with results that people gained from the new lid.

Haha about the sister pics.. and thanks for the compliments!

Just finished one yesterday (it was a pre-paid order, so it's already sold).

I have three more core lids left and I will be making them into high-flow lids as spare time permits. I'm shooting for the end of June to have all three done and available (unless they sell out to pre-paid orders first which is what happened last time).

I'll try to get the owner of the above lid to take a pic when he puts it on his car but he has to buy the silicone connecting sleeve and insert first. But, if you want to see lid pics and installed pics, just scroll through all the pages of this thread, there are plenty of pics!

A Personal Note to {3rd GEN RS }-----------

WHat I think Mikey is trying to convey to you, and was very polite about it, is that your enthusiasm for a V6 part is inappropriate and distracting from this specific thread. It's absolutely great info and has a place as a seperate link and I even learned a couple things off of it.

The Ultimate Focus of the TPI Engine is to mantain Flow-Velocity. Disturb that velocity, say by too large of a intake valve head, or by a break up the air-swirl pattern at the hood intake design such as the too tight factory air lid...

So we're constantly trying to visualize a balanced system in our mind the whole entire way, through point A to point B. So we want lots and lots of continual crisp, quick air flowing into that portion of the TPI system. There needs to be the velocity precision of a maxed out soda straw with no bumps nor any other imperfections. It needs to be flowing perfectly in a directional pattern. The problem is that a straw will only flow so much velocity before it's air speed maxed out, which is why we don't get the high rpms of a carburated system. By Michael enlarging the factory air box, he is, in effect, enlarging the straw. With a larger straw, we can then focus on other parts of the TPI design, such as, now how does adding a RAM AIR set of lower intake boxes change things?

And we still havn't even stepped up to the variables of the several designs of throttle boddies (as you brought up) and their effects to that Air Velocity. If we loose velocity at any point during the intake system it creates total headaches.

Now I lack the vocabulary to explain the process well enough, but maybe you can get a glimpse as to why he was trying to redirect your well deserved enthusiasm. Eventually we'll all be doing that type of work to our Throttle Boddies and/or doing things such as adding Air Foils. In Addition, the Throttle body you select will have to match up to the long term Airflow Upgrades or eventual Forced Induction each step along the way.

So you can get enthused about every sectional part of the TPI system and the fun ways to improve each step of the intake system. But for now, it's just the factory virgin tight air box and the opportunity to 'open 'er up to a usuable air speed that we need to stay on task with!

Great Luck to You as You Wade Through it all! Nitro-Nicky

I think he realized that the stock air-box would feed a mildly modded V6 with ease. Modded V8's are a little more "hungry" for air than what the stock lid can feed.

Anyways,

Thanks for compliments on the lids! It's nice to hear that my time that I put into them is appreciated!

Enjoy!

ASE doc

Gorgeous! Very nice work. Ive been dreaming about doing this myself for sometime. Youve proven that it will work. I would really like to see the design of your ram air boxes too. Ive done functional hood louvres on my IROC. They really help keep underhood temps down. Ill post photos of that this summer.

ASE doc

My old TPIS catalog shows foam filters that are claimed to out flow K&N. Have you seen these? Would they help?

1bad91Z

iTrader: (1)

There is a link on this thread somewhere to my ram-air boxes thread. It has pics etc..

As far as your louvers, I'm sure it helped quite a bit for under hood temps and I do think that mod looks cool! But, if you wouldn't mind, try to keep this thread about air-lid related info, otherwise this thread would be 20 pages long!

1bad91Z

iTrader: (1)

I would stay away from the foam, IMO.

I've seen flow tests that show foam not flowing as well as people think. K&N's are what I use.

I think we need a TPI air flow specific message board. I'm still trying to understand how to get that air speed up to support 6000 rpm, and it sounds like many of the others here who are asking questions are after that type of info.

If you have TPI air flow questions, DON'T ask them here! Mike is busy fielding questions specifically about his Air Lids. We need him to stay busy modifying new ones, not running to his computer every time it 'dings' on this thread!

I'll start a TPI air flow thread that will connect with Michael's labor intensive High-Flowing Vaccuum Big-Block Sucking Double (DD) Big Mama, Must be 21 Air Lids. Nitro-Nicky

I dont have a high flow lid yet. However, my 355 TPI rev limits at 7000 and gets there with authority. I raised from 6500 because I was tired of hitting it every time I upshift from 2-3.

Just to share info, I run 6" connecting rods, 10:1 flat tops with 1/16" low tension rings, Trick flow twisted wedge G2 heads fully ported, a TPIS ZZX cam (240/240@ .050 560/560) Accel superam base heavily ported, TPIS large tube runners, heavily ported plenum, and 58mm trottle body. Trans is custom built 700R4 with auto manual valve body, 2,300 stall.

May I ask what type of guage you're using to measure your RPM scale on? My factory dash unit gets increasingly inaccurate the higher the rpm's go up; so just a curiosity question.
However; whatever was my correct rpm number on my old engine, the rpm number did increase just over 630-700. Nitro

I was going to piece together a quick reference air flow thread that covered all the various separate parts of our intakes; such as: Ram Air-Filters-Filter Housings- and on up, but after taking the time to reread all the *Stickies* to the TPI message board, it seems I've forgotten that most everything is covered up there already with MUCH better detail & coverage than I could ever offer.

Although I did go out and purchase a two piece timing cover so I can switch from a Cali smog legal cam to something 'different' post test. Nitro-Nicky

Update -
I have started production of the pre-ordered lids. I may have two more available that are currently unspoken for. After that, I'm out of cores and might not be making anymore until next year around summer time if I re-supply. I should have all of them finished by end of July.

If ur mod makes these airboxes better than the stock piece fully modified, i want one. Ive got every mod done to my airbox short of reforming it, and it is performing better than i expected. the map is only dropping 4 kpa wide open on a 540 horsepower engine. I can see now why there never were any aftermarket air intakes made for third-gen camaros.

1bad91Z

iTrader: (1)

What mods have you done to your airbox?
Just because you only lose 4 kpa, doesn't mean that your airbox is feeding your motor enough cfm.

My lid not only increases the snorkel diameter, but it also has a greater plenum volume and eliminates the pinch spot in the first bend.

I have one left available for pre-order.

The three lids currently in production for people who have pre-ordered, are almost finished. They are on schedule or slightly ahead of schedule to be finished before end of the month.

DSmith

So does my 383 if you look at the factory tach, in fact I can peg it out with ease. BTW, 7000 on my factory tach is only about 3500.



92RSZ, I'm not running one of his but mine is basically the same. I have a stock air box as well as one modded like 1bad91z's (not don't looks as good). I have no idea what kind of power I'm putting to the ground but you can feel the difference between the two on my car.

1bad91Z

iTrader: (1)

All who have one of my lids all report nice gains from it. I felt a nice gain on my motor with the high-flow lid vs. the stock one.

The more mods done to your motor, the more gains you will pick up by letting it breath better.



On a side note:

The 4th lid in this batch is still up for grabs. It will be the 12th lid I've done for people and I'm all out of core stock lids after this one is modded and shipped.

This will also most likely be the last one done this year due to school starting up soon.

After this one sells, I'll be requiring customers to ship me their stock lid (provided it's in good shape to start with) for modification due to being out of cores and no time hunt more down. There will be a slight break in the price beings you will provide the core.

Ive got ram-air boxes installed (no fog lights), cut out the baffles, smoothed the outlet where it attaches to the throttle body hose, did the coffee can mod so the hose wont pinch shut, and k&n filters. 4 kpa is pretty impressive on a mostly stock airbox, but 0 is better i know.

Don't forget that you need to gut the bottom of the lower air filter boxes to get full benefits of the new lid (no sense choking off the air before it gets to lid)! See pic attached..

Also, you will have to get connecting sleeves (reducer for MAF, or straight silicone sleeve with 4 inch aluminum insert for the Speed Density guys).

I will be putting some more time into them this weekend. Spare time is pretty scarce lately, but they are coming along.

In response to some PM's ....

There are now a total of 12 high-flow lids in circulation (not including mine). I'm all out of stock core lids to make more out of and I don't know if I'll be making anymore this year due to lack of spare time (1 full-time job, 1-part time job, and school). Maybe summer of 2011 when school is out for summer break, I may be able to make more, but this will require you to ship your stock lid to me to modify.

So we'll see next summer, maybe lucky number 13 was the end of the production run!

To be continued...

First, let me say that Im not trying to steal your thunder on these awesome lids. However, I am a fabricator from way back and it feels like Im being lazy if I dont build my own air lid and ram air system. Especially since I have more time to spare than money. I have a question though as I look at my air lid and your high flow lid. It looks like you focused most of your resizing on the bottom edge of the unit. Is this just an optical illusion?

1bad91Z

iTrader: (1)

I raised the whole bottom side transitions to eliminate the factory pinch spots (yeilding more plenum volume while still clearing the factory hood), then modified the neck to accept the 4 inch outlet. Hope that helps!

ASE doc

Thank you. I used Play Doh to check clearance. Lol. There really is quite a bit of room there. I came up with about 5/8".

skinny z

I've always thought that this was one of the most clever ways of adapting the OEM TPI inlet to a high performance application.
Years ago I had proposed combining 1bad91Z's lid with a traditional 14" element base (eliminating the OEM twin filters.)
Hood clearence (with an RPM Air Gap manifold) is the main issue.

Just noticed this post by DSmith. I really dont wish to highjack my freind's thread with this rediculous argument. However, in the interest of truth, I must make this clear. Im an old guy and Ive built plenty of high revving NASCAR small blocks. My engine is an FI version of one of those motors, without the restrictive rules.

Until you build a motor just like mine, with all the tricks that went into mine, do not pretend to know what it is capable of. Even if the factory tach were not reliable, which mine happens to be, my MSD Digital 6 rev limiter is. As is the fuel cutoff point in my ACCEL DFI. When the DFI used to cutoff fuel at 6,500, on a hard pull in 2nd gear, it was quite unsettling. Now when the MSD pulls out ignition events to clip revs at 6,900, it is still quite noticable, if not quite as upsetting. My 355 hits my 6,900rpm rev limit set point WITH AUTHORITY Period.

ASE doc

Back on topic, Mike, my good freind, would you be intersted in making me one of your air lids. The more I think of it, Assembling the materials and doing as fine a job as you do, may take more time than I really have to spare. I will certainly send you my OE lid as a core once I receive yours. I would almost send you mine to modify, but I will need to drive the beast this winter to the shop for brakes and other work that Im doing.

1bad91Z

iTrader: (1)

Thank you for the compliment!

I don't have any more cores to make one for you. I would need your lid to modify.

Also, I won't have the time to do so until summer of next year. (I have a full time job, part time job on the weekends, and part time college student). I don't take summer courses, so if you can hold out until then, I may be able to make one for you.

Brendan91Z

Hey 1bad91 sorry if I missed this but overall did you raise the lid about a good 1/2 inch? Im planning on attempting this myself since I have some fabricating skills. I also was going to do a carbon fiber rap and glass it to see how it comes out as an experiment. Btw awesome idea and nice work man!

ASE doc

Thank you. I will talk to you about it next summer.
