New intake manifold to compliment the new edelbrock head

[krom]

custom billet intake for $400

Make one and cast the rest...
as if the tooling required to do a casting is free, and falls from the sky, and the foundry wouldn't mind stopping everything they are doing to pour you a dozen.


A total POS made in china, sheetmetal intake, for one of the most popular engines in the world the ls. sells for $500, on ebay. A quality custom intake for one of those engines is in the thousands.

With the potential volume, there is no way any one could design, test, and manufacture for near the price guys on here are asking for. Hell at $400 a pop, you couldn't do the R&D, nevermind building one


This chinese POS 4 cylinder intake goes for over $500

Krom,
Before you ass u me I was stating cast was cheap and at flea bay rates I wasn't. I was stating through my statement yes cast is cheaper vs. billet and machined. Who the hell would cast a dozen you dip stuff? You would cast hundreds to make it cost effective and then yes you may get a foundry down enough on the price. Lets me ask ass u, have you priced it in cast at hundreds before desktop dyno the statement (ass u me) I am nuts? By the way, (me) means me not you.

Really I am not surprised, you are likely one that runs 20/50 Rotella in your engine too when it needs 10/30 .

Krom you're exactly right. I'm trying my best to get the cost below $1,000 and that's charity work. With me eating all the costs of r+d and many of the other production costs.

Also a cast design would require all new r+d as it would be substantially different than the modular billet design I have in mind.

Most billet intakes are $2500-$3,000. I'm trying to get the jeep community the same quality and get you guys to stomach half the price. I'm not trying to get rich off these, just contribute to the community and cover my costs.

mountaneerjeff,

That's great and I am not meaning to rain on a parade but here we go again. I have average build on a 4.7 stroker
with $1800 in mocking up, machining, and assy. $2000 in parts for blocks heads pumps etc cuz i don't half ass it
while its apart. Another $1600 in fuel injection/ignition work etc. and now we want to toss another $1-1.5 k in there.

Hmm, geez I'm at $5400 with a cool set up, (lot o fooking headaches getting there with a 7120 head), and an intake added puts me now then @ $6900 smacks.
Why don't I just LS the deal and call it a day? I mean the stroker idea is cool and all but it's getting hard to find items to build and if one doesn't hop a stroker up a bit more to take advantage of what would now be equivalent to a tunnel ram, it's pointless to even think about. Can you imagine a tunnel ram on a stock small block?
Like fitting a fire truck hose into your sprinkler for the yard! Yes it would elevate the Edelbrock head. Does it make sense? Not for most.
Now if you are dragging it in sand mud asphalt etc at WOT on a heavily modded stroker, then god bless ya and send us some video bro.

Here,
By the way, NONE of you mentioned CFM capabilities.
I'm gonna let all the desktop boys in on a little secret. It's called CFM and here are the specs on the jeeps 4.0 and suggested 4.7 specs.

Specifications:
Stock Jeep TB: effective bore dia: 54mm, effective plate dia 59.8mm inlet dia: 62mm Effective flow rate: 415 CFM (being generous)
Stock height from mounting flange: 65mm
68 mm Jeep PERFECT Hi-Velocity Throttle Body: Effective bore dia: 68mm. effective plate dia: 68mm, inlet dia: 72mm Effective flow rate:750CFM
PERFECT Hi-Velocity Throttle Body height from mounting flange: 73mm
Intake manifold port size: 62mm

Now do you understand my "tunnel ram" thoughts?

Here is another secret: Get you an older 4-6-8 intake from Clifford, yes they still make them even NEW $ 319.00, and port it to gasket match. Then get you a GM TBI kit from Howell and be done with it. You'll need to mini mod the pin alignment holes on the intake a touch to the head but welcome the info and save big money. You'll end up around 650-700 with some massaging on the CFM if ever needed fitted to a 7120/0630 head or heck get ya an Edelbrock.

Jack Clifford got some of the best results from a Holley 390 CFM carb for god sake!

Best to all the desk top boys out there on this thread.

I've said this before about the Edelbrock head and now I'm going to say this about an aftermarket performance intake manifold for the Jeep 4.0/stroker crowd. Why didn't anybody cast one ~20 years ago when the volume of sales would have been much higher, or even 15 years ago when the first strokers were appearing on the scene?
Making one ten years after the 4.0 engine went out of production will cost a good deal more in real terms 'cause the market's now much smaller. Even at $1000, I can't see it being cost effective for the average stroker enthusiast especially when combined with a further $1500 for the Edelbrock head.
With the cost of used Chevy LS V8 engines coming down, they're becoming an increasingly attractive alternative to the high performance I6 stroker especially for those who have an AX15 manual tranny.

P.S. I've just realised that this is my 2000th post!

Because Edelbrock did Not have the foundry size to produce a head as long as a I6. They Just got a new facility and ability to be able to do such a long casting. SO Now is when they released it.

An aluminum Jeep 6 cylinder head has been available for much of the last 10 years from Hesco. True the price point was $2K. I have no real idea of how many heads Hesco sold. I do know Hesco is not willing to spend the $150K required to replace their tooling to keep the HESCO head on the market. That should give you some indication of what HESCO thinks of the market now. I hope Edelbrock makes a bunch of money on their aluminum Jeep head. For what it is worth, I do have a HESCO head for a future stroker. But very frankly, I think money is better spent on the cast iron head or spent on something else.

Also for what it is worth - I watch a group of three custom intake manifolds built this Saturday. Much like the proposed design here.
Only trouble - they were for a turbocharged Toyota Supra. I did not ask what the selling price was. Maybe I should have.

Krom,
Before you ass u me I was stating cast was cheap and at flea bay rates I wasn't. I was stating through my statement yes cast is cheaper vs. billet and machined. Who the hell would cast a dozen you dip stuff? You would cast hundreds to make it cost effective and then yes you may get a foundry down enough on the price.

Really I am not surprised, you are likely one that runs 20/50 Rotella in your engine too when it needs 10/30 .

At the sales volume we are talking about, billet is cheaper than cast, without the design its impossible to figure the break even point. But would you front $30,000 to $50,000 out of your pocket for this project??

If you are bored, and want to figure out how much it might cost try this: http://www.custompartnet.com/estimate/sand-casting/ don't forget to add the core, and machine work

I know some guys near detroit that could take the cad file for this, and in a couple days hand you a composite manifold that you could bolt on and run, cost may be comparable to billet aluminum, but I haven't worked with them in quite a while.

[CandyCaneXj]

Anyone ever consider being a part time welder and making these?

[Cheromaniac]

Hesco dabbled with the same concept (dubbed the "double trouble") a while back but I think they've abandoned that idea.
Kudos to anyone who can pull it off and make it work.

[SIXPAK]

Anyone ever consider being a part time welder and making these?

Hmm, that intake seems famaliar! lol

[CandyCaneXj]

Who made it? I want one! haha

[mountaineerjeff]

Anyone ever consider being a part time welder and making these?

you do realize thats my pic, right? lol.

The intake manifold is still a work in progress. like most side projects itll take a little time given current priorities, but I havent forgot about you guys.

[Cheromaniac]

Here's a pic of the Hesco "double trouble" to refresh a few memories.
