Aluminium Manifold?

[alun n]

...well, yes, but its mines...precioussssss.<br>
<br>
Oh, all right then. I was thinking of selling it for lots of money as I can't afford the webers to stick onto it so I"ll devalue it by replicating it instead! But you are right Scott; Club supply and therefore Club benefit.<br>
<br>
Friction? Well to the uninitiated I thought it the simplest explanation. Obstruction, change of direction, particle collision yes, exacerbated by friction from the sides of the vessel which even with a gas its contribution should not be underestimated; even with the best gas flowing preparation at molecular (or even particle) scale the surface would still have huge chasms evident which would interupt and slow the gas.<br>
<br>
Then of course as the particles slow down may have a contributory cooling effect on the gas...<br>
<br>
Then there is the coander effect which as the gas cools and slows it drops away from the sides of the vessel, the dropping particles having further retardation effect on the particles which are still in directional travel, but at 160 psi plus this probably happens much further down the exhaust...<br>
<br>
Specific heat capacities of cast iron versus aluminium...<br>
<br>
Air flow around the head versus the manifold...<br>
<br>
Effect of the fan...<br>
<br>
Differential of heat within the manifold which can be coped with by Cast Iron but probably not by aluminium...nobody wants a warped flange!

What a response!<br>
Gone a bit tits up at the mo as we have so little work on<br>
all the pattern shop and foundry have been sent home for 3 weeks!<br>
Patt man says the core box would be a long time making<br>
if done in lunch times ( I'd never dream of doing homework in works time , honest! ) the inlet man for the webbs from memory would be a lot simpler. Sounds as though the original plan wouldn't have worked anyway...<br>
Best laid plans an all that...<br>
if the inlet man seems a goer, i'm prepared to do the leg work to make it happen, can even get machined faces/<br>
fixing holes done no probs! Though most you guys seem to have huge garages full of bridgeports ,lathes and spray booths.... im struggling with no driveway, not much money and a happy shopper skt set.<br>
Any one got a pic of said fanimold (luv that term )<br>

My wife's already got a warped flange!

Not great. But I hope it gives you some idea.<br>

some of us have to go to work Dave....then wait me turn<br>
on pc (2 teenage girls+MSN = long wait)<br>
Cheers carsreunited for pics. Appear to be 4 x straight through which would be easier than the ex man as thats<br>
2 inside 2 if u know what i mean..would be easier to make core box/pattern.<br>
Spookily, those pics were taken on my B'day, shame thats not me prezzie.<br>
Wife gave me socks (miss heard me when she asked wot I wanted)

I was just referring to the flange bit. I was sat at work most of the afternoon wondering whether I should post something similar...<!--EZCODE EMOTICON START :D --><img src=http://www.ezboard.com/intl/aenglish/im ... /happy.gif ALT=":D"><!--EZCODE EMOTICON END-->

[ddu]

my missus would probably like the idea that someone was thinking about her flange..<br>
all afternoon though? wot a job you have Dave

It is Phil. You want to see the plumbing from the drivers seat to the bag!<br>

O.k Got bloke sorted to make all relevant pattern equip<br>
But is there a demand for these?<br>
Pattern time/development costs are lookin about 2K!!!<br>
Willing to stand this but dont wont to knock 4 out over 2 years!<br>
To make viable need a large amount of interest/buyers<br>
also, I love my dolly and all things related , but dont wanna do all this without me making dosh on it.<br>
Is it patented still? lots to confirm b4 I do anything..<br>
Also, would need one to look at/work from.<br>

They go for about £150 on ebay. This 'value' will diminish as supply outweighs demand.<br>
<br>
I doubt you would get 20 orders at £100 each<!--EZCODE EMOTICON START :( --><img src=http://www.ezboard.com/intl/aenglish/im ... /frown.gif ALT=":("><!--EZCODE EMOTICON END--> <br>
<br>
I know the pain in such investment. The repair panels I have made just about pay for themselves by the time stock reduces...and then stock needs replenishing!

Economics are looking a bit shaky on this! I initially thought you were talking about a lunchtime job to get the tooling done on the cheap. Do you have a part cost on top of that tooling? If you do go ahead, you could probably sell some to Sprintparts in Oz.<br>
<br>
Did you see the thermostat housing? And the injector bosses? If anyone wanted to run injection it could do with some bosses for attaching a fuel rail too.<br>
<br>
Great idea though, if you can get the cost down.<br>

Passed pics onto pattern maker, he's aware of whats involved.with the right info on injectors,location/angle etc, an extra "pad" could be added to the pattern for people to utilise if req'd,or simply leave or grind off if not needed..<br>
it seems a shame that these resources and my contacts in automotive tooling maybe wont be used..<br>
been quoted about £30-35 per casting and £25 for M/c<br>
These are from third parties as our overheads are pretty high and this reflects in our hourly rates..<br>
