Would anyone be interested in an roots blower manifold if I manufactured one?

[firebird_1995]

Its the oem unit used on the gt500. I didn't do the twin mount. That was pocket on ls1tech. Gene Zebley did a custom intake for a whipple (i believe) on an impala. I actually spoke with him last night about another build I have been working on. It was very well built but it couldn't be tuned and managed to twist up a few rods in the process. It was a low profile mount. I'll try to post some pics of it.

Interesting. Correct me if I'm wrong, but the Cobra m112 points to the passenger side and the GT500 points to the drivers side.

I really haven't started looking for a tuner here in Houston. Everyone here is much more interested the the LSX than LT1. Swapping over to the 24x should solve it somewhat, since its essentially just a Chevy Express van.

Let me know if you stumble upon those pictures. I've very interested!

M122 inlet is on drivers side

You can discard my no thats fine. The reality is though that most people who say they will buy something wont follow through when it comes down to it because they dont put any forethought into a project. If you get 10 people who say they will buy it expect two people to actually poney up the money.

Look around on the forum and look at all the builds where people say they are going to do something and don't. Plus I dabble in a lot of hobbies and I can tell you I have seen tons of stuff like you want to do . Most times they don't get passed the drawing board. When they do like I said most times the people who said they would buy bail . Ill be impressed if you can do it for the cost you think you can. Because a member of another forum had a foundry cast intake grates for a jetski and the grates cost half of what your estimating your intake to cost. They are a fraction of the size and complexity.

Wow, that's a beauty. Sits a whole lot higher than what will fit under the fbody cowl.

Under promise and over deliver. I really hope the cost isn't that high, but I'd rather say $700 and bump it down than say $200 and have to move it up. I realize that while 10 people say they are interested, only a few may buy. Its more about the interest in a roots manifold being on the market. Having the option instead of being stuck with a centrifugal super charger. But when you vote no on an idea based on the fact that FI isn't cheap, your not providing anything useful. You wouldn't be interested in any FI application, but again that is my fault for not wording it correctly.

I also completely agree that most projects never go completely through, but that's not how I work. Personally when I have an idea, I first approach it every possible issue that I will need to over come. I put a great deal of thinking into the idea before I started the previous thread.

I have quite a few things I've built that people have said wouldn't work:

The cast is near completion, with the exception of a modification to the outer pannel. I stopped updating the thread due to a lack of response by the community

Not to be rude but big difference between building a computer and casting parts. Your seem to be an entry level back yard enthusiast when it comes to this. You said in another thread that all you have ever cast was some trinkets so once you get the initial design will you incorporate an actual foundry or just do it all your self. From what you said you will get all the aluminum free my guess is that this means scrap aluminum will be used to cast intake manifolds you plan to sell. How will this effect the casting as if it is scrap metal how can you be assured of the grade or quality of the aluminum. As posted in another thread several concerns have arose to the how you actually plan on casting a piece like this. how are you going to machine the mating surfaces?

I think these are legit concerns. If you are going to sell parts to people you have to sell to quality parts you cant just wing it and sell a bunch of manifolds to people and make it their problem. I followed the project of have the intake grates cast. I can tell you now that the foundry they used wouldn't do it unless it was a large order. They needed to sell at least 150-200 at a rip.

Another thing to think of, or not forget, is that casting is cheap process for a reason, it gets you sorta ballpark to final product. You will still need extensive milling on the intake flanges, where the intake meets the block areas, and where the blower mates to the intake. Then you will need to make sure you can control your mill work for the hole patterns and threaded inserts... castings are tough to control shift etc, and if this is a backyard endevour, be prepared for a lot of trashed molds until you can get things to be semi consistent.

I sound pessimistic but doing casting stuff in terms of CAD and semi big runs, is horribly time consuming. Casting design work is one of the trickiest cause of the non exact process of casting itself.

I understand the difference between casting aluminum and building a sheet metal computer. Like I said before, The aluminum would be from either a bad LT1 head or a cracked LSX block, depending on how many I decide to make. I have full faith that the aluminum (once chemically cleaned) will be pure enough to to use.

For machining the surface (SC plate, heads, block) I plan to try myself with a milling machine at my buddy's shop. If I feel that I don't have the skill to mill them correctly, I will pass it off to a local machine shop. I plan to at least try and mill the prototype myself, if it comes out straight and true, then perhaps I will continue milling them myself, if not - machine shop.

I also don't expect orders to pour in. What will more than likely happen is I make one for my T/A, my buddy's truck, and maybe 2-3 extras for the future. If I sell out of and need to make more, then I'll make a few more. I understand what you mean by quality, I wouldn't ever want to sell something that causes harm to another LTX member. I would be putting my name on the line if I sold half-ass castings that didn't fit/caused damage. My username is my REAL name. I can tell you, there are not to many Nate LeDuc's in Kingwood,Tx.

I get what you mean, where the manifold meets the SC mounting plate will need to be milled true, the block/heads will need to sit flush, the ports will need to match up reasonably well. I plan on over sizing the mold about 1/8" to allow me to machine if to the correct size. I've put a great deal of thought into the casting design. I'll post pictures once I start the design, but I do agree, the runners are going to be extremely difficult.

Well good luck to yah. Post up pics of it as you go along. If nothing else it will be interesting. I honestly hope you succeed.

Much appreciated. I'll post updates as I go along.

I'm still interested in what everyone else has to say!
