Seems like somewhere, somehow, $399.00 was mentioned, guesstimated, or assumed (judging by the title of this thread).

i really do not kno y all of yall are bein so impactient, just think all this time as time for us to save up money for more mods for our cars, jeesh, and stop callin Bryan out, Because hes the only one that actually knows sumthin about this intake
I'm going to talk to my boss about posting some pics of the proto set-up.
It's a touchy subject, so please understand if he says NO that it's not to put you guys off, but to protect us from getting nailed by some off shore manu-copier ripping off our design.
The press release that was posted on our site was a bit pre-mature. I do apologize.
Unfortunately, the marketing dept. often gets ahead of the R&D & CNC depts.
The time frames set by the marketing dept. are very realistic, except that it doesn't account for the other projects that are still being worked on.
Regardless, the TPI intake is being worked on now.
No one deserves to be put on the spot like
that anyway in front of the entire site, regardless
of seniority. It could have been stated in a more
respectful way.. but as you say, its a touchy
subject.
I look forward to any information you can
squeak by the higher-up's.
First and foremost, there's a ton of defintions of "TPI". Is this intake going to be a tradition style LONG TUBE runner(SLP/AS&M/FIRST), or a stealthram/superram/miniram type modified intake?
Spoke to a few people over @ Summit Racing that I know. From what they told me awhile back, it'll more than likely resemble SLP's T-Ram design (below pic is for the Mustang);
However, rumor has it that they're now trying to emulate their LS1 design for use with the forgotten TPI engines. If this is so, they'll make a killing (so long as it's reasonably priced, of course)....

I sincerely hope it does NOT got that route.
The LTR must stay.. not that I dont agree with your
statement.. that it would make a killing on sales.
I think it would be smart to develope both LSx and
LTR option for the LB9/L98 line.
I believe it would need to be factory in appearance
with flow and porting capabilites casted in the aluminum..
The biggest problem we TPI guy's have is no metal to work
with.. We can't take what we dont have..
Lingenfelter LS1 intakes cast more metal into thier
design for extrude hone and other provisions..
Only if the Tuned port plenum/runners had that option.
I would like something along the lines of the FIRST
TPI system, but have a more true OEM appearance.
It's pretty expensive but there is a marine intake that is based on the LS1 style intake manifold that will bolt onto our heads. Not smog legal and I forget the name of it for the moment. There was a picture posted recently.
I'm really looking forward to see what the BBk intake is all about. Next week I'm starting on my First intake manifold conversion. If the BBk looks like a better idea I might stop work on it and go the BBK route. By the way my First intake manifold was flowed at 301cfm right out of the box.
In the photo above with the Mustang style intake I'm not sure of the hood clearance especially on the Pontiacs.
Well the boss man wants to wait on the pics until I dyno it. But that's going to be this week for sure (RTV is setting up as I type).
I can tell you that there are no similarities to the SSI intakes for the LS1 or 5.0 in this design. We did not copy or modify any other design.
It's a clean sheet.
It's very difficult to get away from the lower intake's stock design, but we did our best.
The runners are 1-3/4" tubes, they turn straight up from the lower and a plate sits right over them. The plate is the bottom of the upper. The upper is a wide, flat-ish box design that mounts to the plate for a large common area.
I hope I can post pics soon. This is like playing charades over the internet.
Unless part of the round tubing is also the intake manifold. Just thinking. Does sound like the Supperam though.
I was hoping the round tubing would be like 1 7/8" in diameter. With a .0625" wall on 1 3/4 inch tubing that would leave 1 5/8" id.
On 1 7/8" tubing and .0625 wall that leaves 1 3/4" id. Or go 1 7/8" tubing with thicker wall and allow us to hog it out or Extrude Hone it. Our 400hp plus motors need to breathe. Will wait for the design so we can critque it.
I for one I'm glad you are comming out with it. The basic design goes back many years and needs some serious improvements.
There are already enough 'stock' TPI options out there, we dont need another one. A totally different design would be nice. Those that want stock appearance can go get an Edelbrock base (or dig up an old Accel), ASM runners, and port their plenum. Thats about as far as something relatively close to stock will get you, with the too-long runners on a TPI.
I can tell you that there are no similarities to the SSI intakes for the LS1 or 5.0 in this design. We did not copy or modify any other design....
I think it's safe to say that me and just about every other TPI enthusiast out there have seen just about every conceivable configuration possible. All that honestly matter's now is how it performs. LT1 Conversion, SuperRam, Holley Stealth Ram, MiniRam, and my all time favorite, the T-Ram;
I'm glad that we'll be seeing pictures of it very soon Bryan, but I'm highly anticipating how it performs on the dyno. In all honesty, it doesn't matter how it looks, it's how it performs. As we say in the financial world, "we don't pay for potential, we pay for performance". Hopefully your higher ups will give you the nod to strap that thing on the dyno very soon....
man i sure to hope this intake will flow good enuf to feed a 500hp stroker motor, and if not it looks like im gona have to do a LT-1 conversion, hope this thing really flows Bryan
Hey guys this has to be a win win situation. I can tell you I love the superram but its a bitch to install and the price will give you a heart attack. If the price is right its a better deal trust me.
Even if you don't go for a CARB number with it . I would LOVE to see provisions for the EGR included . Up here in ontario ... we only need to have the stuff their ...not a registered part with EPA . I would get one if it had them provisions ..... I would get the stealth ram ...but NO EGR provision

Son of a....I bought AS&M runners because I thought this was a dead issue. In control-freak California it would help to have a CARB number, or at least EGR provisions, since many testers will look for equipment rather than EOs...in any case I'm glad someone is taking a shot at helping TPI guys out
Put me down for one. Believe it or not, I still have the rebuilt 350/ZZ4 cam/AFR 180 motor sitting bagged up on a crate. It will be going in the 92 convertible T/A. It's a really clean white car with a black top that's been completely gone through minus the engine. It'd show off the new manifold well.
Bringing this back up for my design wish list for the new BBK TPI.
1. Have the "intake manifold runner" at the head be straight into the intake port of the head. Not at an angle that the stock and Edelbrock manifolds have in common. There would probably have to be an arc at the fuel injector area of the runner.
2. Have plenty of material on the intake manifold where it bolts to the head. Maybe enough so that it can be easily opened up to a Felpro 1206. In BBK factory form a Felpro 1204 opening would suffice for the stock motors.
4. Have the capability of opening up the intake runners to say 1.75" inside diameter. Same at the intake manifold where the runners bolt on.
5. Material. I would like to see a thermo plastic for minimum heat transfer. Cold air means more horsepower. But if aluminum so be it.
6. Ensure that there is enough material so that bigger throttle bodies such as the twin 58's will fit.
How many people are going to buy this manifold if it requires spending another $500 on another throttle body? I know I sure wont.
Bryan, you probably saw the $3000 price for a SuperRam, but that is for the conversion kit for a carb car. The manifold, runners, and plenum price for a TPI car is about $1000.
Also, in regards to 1989GTATransAm's #1 point above, here is my thread about the way the stock TPI and aftermarket TPI intakes route the air to the heads. http://www.thirdgen.org/techboard/tp...-manifold.html (Visual TPI intake manifold ports)
Thanks Kevin for the post. Bryon if you see this look at Kevins post and pictures 1028 and 1030 and the right molds in each.
You can see where JerryWho altered the Edelbrock runners for a better air entry into the head. You can see the arch. Best if you can do the floor and roof. You may have already done this. If so disregard.
Also if you read through Kevins thread the deficiencies of the current designs are spelled out. With the fresh BBK design they should be easy to cure without difficulty as you are still in the prototype stage.

Thats very interesting. I see Jerry did his homework and looked for the restriction points rather than just wacking away material to make everything larger. One of the biggest mistakes with porting is thinking to make everything larger but in reality this could just be slowing down the intake charge and just enlarges points that didnt need it. By doing this he discovered the most restrictive point and modified it well. I wouldnt mind a tpi intake that could flow 300+ cfm.
I got it started and running today, but they sent me on a delivery truck run that took most of the day .
Unfortunately, having been a chauffuer for 5 years, and a mechanic/technician for 13 years (on and off, but mostly on) over- qualifies me to do alot more than just wrenching at BBK......
Anyhow, I was reading the thread here, and I can reply to some of the questions and wishlist ideas.
The intake will be made entirely of aluminum. The upper box portion of it will probably be die cast for light weight.
It features twin 58 mm bore openings. There are plenty of guys out there with '03-'04 Cobras that make 500+ RWHP with their stock TB which is a twin 57. Of course they can make more with the twin 65 that we offer for that application, but I think I made my point that a twin 58 is plenty big enough for 99% of the TPI crowd.
The idea is to have everything including EGR in the factory locations. These cars are not fun to install intakes on and I dodn't want to make it more of a pain than it has to be, so the single bore throttle body idea is not going to happen.
It will have a low enough profile to fit under a Vette hood. I tore down a Vette intake for the original design sessions. That is where all of the test fitting was done, on a Vette.
Thanks for all of the input guys. It's really helpfull.
In all honesty, That's my determining factor.. sadly
Id rather bust my hide getting a stock Tuned port to
flow nicely or grab a FIRST injection system if it is not
of my tastes.
The look of TPI is infectious, now we gotta figure
out how to get it to flow over 300cfm. Like Allen
or JERRYWHO.. accomplishing the impossible, or
so it seems..
Thanks Bryan for the reply. Just want you to keep an eye out for us that want to run the BBK TPI intake system on the higher horsepower applications. Just put in enough material around the key areas(runners) so that we can open things up abit for more air flow.
Right now I'm progressing on my highly modified TPI intake system but if your design is good enough I will stop in a heartbeat and buy your system.
As I have to have a CARB number to smog, and given the limitations of the stock TPI system, this BBK intake might be the reason for me to buy a 3rd gen.
How many people are going to buy this manifold if it requires spending another $500 on another throttle body? I know I sure wont.
I agree totally !
Glad to hear there will be an EGR in he stock location . It's sweet that BBK is takeing this seriously I will pretty much want one .... after we know the end results ... thanx for listening man !

I know a guy who'd take those runners off your hands, hehehe.....
Pending how this goes I might have the ASMs on the market. But then again, if this goes well nobody will want them Watch all of us from that GP trying to sell off runners left and right.
I can't wait to see the BBK intake. By month's end I should be putting the 383 together and if this clears a Vette it'll probably clear a Formula.
If this thing hits big, Id expect to see alot of wares
up for grabs.. let's just hope some TPIS LTR's become
available for the guys who wanna run stock setups.
I know ill be on the hunt for another set of some
large tubes for my other TPI car. Ill more than likely
pick up the new BBK intake for my daily driver, if..
That's a big "IF"..it looks, & performs to my street
car standards. Which is simple really, being faster
than everything from dig.
I know this may be getting about of ourselves but Id like to see us set up a group purchase for this intake. I know its probably going to be atleast a few more months before its finalized. Even if it required a deposit to ensure they made one, Id be in.
I will be most interested in the basic design and how easily it can be opened up to air flow for higher horsepower cars. I don't expect big numbers from the dyno on a stock car with the new BBK TPI intake system. The exhaust system on third gens needs to opened up to see nice improvements with changes on the intake side.

Cant wait!
Roger that. This could really change how people view the 3G cars in smog-test states if it has EGR.
I think that if the BBK setup extends the RPM range past 6K for strokers I'll be in the market for one. The only thing I'd miss is the look of the LTR setup. But in the end, it's as you say inasmuch as it has to really haul the goods.
