wow this was an old thread. i still think bbk should bring out a small block intake. this isnt just for our cars, but for any small block. i think they have a market for that

why would you care about an EGR, I mean being from canada and all?
We need to have it up hear. If it came with it , you have to have it . Thast why I care about the EGR . I would have had a stealthram already if IT had one too.
i know i would if it was 50 state legal... but i said screw it, and decided to do the LT1 intake conversion. finally gonna dump TPI. a 350 motor peaking at 4100 rpms just doesnt do it for me
a 350 motor peaking at 4100 rpms just doesnt do it for me
Mine peaks at 4900 with the crappy stock heads/ZZ4 cam. Others are peaking higher than that too. One guy is makeing power to 6000 rpm on here . With TPI . Just wanted to toss that out. Sure it takes some work but it can be done. Not saying it's the best idea to go with .

Kinda funny, my '86 Prelude Si tops out at ~5600. Not that high in comparison to a pushrod V8 for a SOHC 2.0 gutless Honda thingy. Good for commuting -/+ 3000' of elevation though.
BBK hasn't completely forgotten the TPI's. They have an AFPR and intake gasket kit, and several throttle bodies as well. Not very complex but it is something . . .
They haven't put out a 4.6L intake manifold, so hey, there is reason to not give up on them yet.
Hey, I got a message back from a Brian, a honcho in R&D IIRC, at BBK. He says that the TPI design is still in raw casting, no maching work has been done nor has a prototype been completed. Because of other, more pressing projects they won't be getting to the TPI design until this coming sumner most likley.
Wow that's promising news, I can't wait to see how this thing compares to the Stealth Ram. I wonder if it's the LS1 style intake, or if they went with the dual plenum style like the Mustang's got. It'll be interesting to see if this materializes.
Guys, I don't know if anyone has checked the date of the original post!
It has been bout 2 years to the date. (- 2 days)
If this had even a chance of making them revenue, it would be done by now.
Maybe when thier business slows down to the point they are scratching for product ideas, then maybe..maybe this will be looked into being finished.
I don't see it ever happening and glad I didn't wait.
Just FYI, I visited the BBK engineering facility a while back, and they have a finished prototype base, but the top isn't yet even roughed out. They told me that they had back-burnered it because they had been concentrating on the red-hot Mustang 2 and 4 valve modular motors, and now are hard at work on an intake for the new 3 valve ('05 and later Mustang GT) intake. I can understand, its a much better market than the TPI stuff. I don't know if they'll ever get back to it, but it was in the works a few years ago.
Well after a very dodgey phone call with them. All I could get was " If there WAS an intake ( IF) it wouldn;t be released untill at the very least ....the end of 2007.

I spoke with Brian Murphy, president of BBK on Saturday regarding their TPI intake. They have not ditched the TPI intake idea, they are still going ahead with it. They are working on setting up tooling and equipment to manufacture them, and he was explaining to me that this is often a time consuming process. I spoke with him regarding some details as to the intake's design, but he wasn't sure about some aspects of the intake, which leads me to believe he is not involved in the intake's design directly. To my understanding, the intake manifold, runners, and plenum will be one piece. I assume this would mean that there will be fuel rails included with the manifold, as the stock rails probably won't work. Runner length will be somewhere around 16-18 inches.
As far as availability, its looking like it will be available in the second or third quarter of 2007. I understand completely why this project has been in the works for so long... there are markets with larger demands than TPI, and those would obviously take priority.
The problem I see is what motor is the new TPI going to be designed for? Will it be a compromise that will include the 305 motor? If so it will hurt the 350 and up crowd.
Maybe they will make two. One for the 305's and low end 350's. Then another for the high output 350's and 383's.
I hope the runner length includes the heads. If not that is to long. 16-18 inches is OK if it includes the heads. Also the cross sectional area of the runners and intake manifold need to be taken into account.

I would it expect it to be runners and manifold (more mid power).
Stock manifold runner length = 8"
Stock runners = 11.25"
Stock heads = 6"
Total Stock Runner Length = 25.25"
I just happened to find you while Googling "TPI intake."
I'm finally test fitting the first TPI intake proto on an 88 IROC here at the BBK R&D facility.
As long as there aren't any major set backs, I'll be dyno testing it on this otherwise stock car in the next week or two.
At this time, I can tell you that it is in "working prototype" form and I am not authorized to post any pics right now as things often change quickly.
I will post dyno results on here as soon as I get them. The runner lengths and all of the hard details are still open for modification based on the dyno results so please be patient.
Hopefully this is good news for those who are interested . It looks to be a promising product for those in need.
I'll post up with the info ASAP.
One more thing-
I can't respond to every post here, but there is one subject that I will address.
BBK and Edelbrock have not been partners for about 5 years. So don't worry about any cross-marketing, or re-badging of their products. I know there are lot's of you guys out there that have BBK EDELBROCK on your throttle bodies that are going "what"? right now, but don't worry, it's all good.

Bryan, your post should create a fire storm. Some of us on here are working on modified TPI systems and have some experience with test results. I hope you are open to input and critique. What the market really needs is a TPI system to cover the modifed 350 and up motors or really hot 305's. Some of us live close by to your facility if you would want some input.

Given the different dynamics between the base 305 and say a high strung 383 stroker, what are you guys designing for?
Runner length is part of the problem along with the CSA. This can be addressed in various ways and I hope you are open to suggestions. Another is the entry angle of the intake manifold runner into the head. Another is the cross sectional area of intake manifold runner. Don't know if you are making a plenum or not? We have some ideas on that to.
Sounds very good. I hope the 1.75" diameter is the inside of the runners. I know that csa by heart. Hehehe. 2.404 square inches. Now if the intake manifold runner is also 1.75" diameter and gently tapers to say 2.00 insq at the head you might have something. Actually it needs to taper to less that 2.00 inch squared for stock heads but if it can easily be opened up to meet the minimal CSA of the aftermarket heads that would be real good.
Also the entry angle into the head needs a nice radius and not a sharp angle as on the Edelbrock TPI manifold and the stock one.
IF this is true, its great news. it will open up a great option for those of us who want to stay with a LTR TPI intake.
hopefully it will have provisions for EGR.

not from the horses mouth you haven't ... all other stuff was hearsay

It's a large, open plenum with 1-3/4" tube runners that bend down into an all new lower intake with larger than stock ports.
I have a few questions that I'd love the "horse" to answer!!!
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?
If it IS a long tube design (good for us stock nazis ) what are the performance expectations/goals? Maybe I should allow you to be a little more generic: Would this compete with a ported plenum, and aftermarket runner&base combo like Ede, SLP, TPIS, ASM etc. etc, or would it be more like the FIRST system which is a legit choice for higher end performance?
Another plus for you to keep in mind are those of us who need intakes that will stay under a sock hoods with a strut tower braces. In the next year I'll be looking for a intake to feed a strong (360hp) high rpm 350ci engine.

don't get me wrong, but i understand how management works sometimes. they just kill a good ideal for no good reason. unfortunately, the bean counters are needed, but too many times they seem to not understand whats going on.
i don't know how much you poked around here, but i think you can see what a good LTR TPI intake means to the guys here just from this thread.
thanks for letting us know that the BBK TPI intake is alive & well, im looking foward to seeing some pics
a question i have, will BBK make a base for the later model Vortec heads for us gen1 small block users?
Seems like somewhere, somehow, $399.00 was mentioned, guesstimated, or assumed (judging by the title of this thread).
----------
Hmmm. I wonder why I have to click a box if I want my sig to show up when I post......
Being that this is totally fresh, I'dd love to see it beat out all the others (LTR,SR,HSR,MR) I'dd buy one I would think then.
And fit under a TA hood with a STB (yeah, I know that's asking alot LOL)
