put 3 pairs down for me, any more views in DXF?

can be a tad shorter if you like will save money in a cnc model and will suit bonnet clearance

hey i finish the first prototype drawing of the castings

if i can get a group buy for these mini manis i could get them cast pretty easliy

Will be good to see some cad pics if possible in time and the beauty of these mini manifolds is a log style turbo manifold can be designed to be more compact and neater straight out.

ok kids im back again i been layed up with a bad back but im starting to heal abit now so hopefully it will be full steam ahead now again

seems this is a good topic to head into im gonna get some flanges cut asap and start there with welded 90 deg bends with a flowed join like you pic while i work on the billet drawing and the bends with have blocks welded on as then injectors can be added at a later date

No I know you are not been nasty but you often fail to read the whole thread, either way it was mentioned that these would suit a variety of setups never a blowthrough turbo but if thats what someone wants to do its up to them.

To repeat this is not the easiest thing to make as you suggested earlier and saves alot of hassles.

Its ideally a small part for HyFlo to play with using small billet pieces by separating into 2 units that can be used in a variety of ways, if you want something more substantial with equal runners or more to suit your needs it wouldnt be cheap or simple.

This is something to suit the tinkerers out there that either want to go carb, turbo or many efi. Never we talked about or suggested blow through.

So to wrap it up... it will suit
twin carb
sucky turbo plenum
and efi if need be

carby turbo can work if you set it up as suck through, as you are now suggesting, but i was thinking you said that the carbs would be manifold mounted, making it a blow through setup

is that mightyboy the bloke i would have seen with his mrs in a mightboy too at a jap classic day? looked cool, suck through setup

i'm yet to see a regular motorsport car with carby/turbo and that would certainly be because of reliability/maintenance issues

the design would benefit from a flat surface for injector boss install if wanted

I am semi-interested in this as i have the ability to draw/design and have cast such things, so dont think im just being nasty

so what is the main purpose of these? to mount two carbies or for a suck through turbo setup or injection or just any of the above?

carby supercharger works well been in plenty of them now
There is a professional installer of superchargers with
a mightyboy 660cc using an SU like for most of his customers
and there are no issues goes like stink day in day out.

carby turbo works if you know what your doing most dont follow through with a full dyno or have the time. Lots of little things like water/meth injection are not implemented and there are plenty of carb A series that have worked in the past. Not to mention there are tons of A series minis running all over the world with inferior cast iron heads doing it and doing it right.

The "runners to the inlet ports" are THE HARDEST to manufacture, make or produce from scratch, to weld a bit of pipe on the end of these to suit is plain jane easy and takes alot of the headaches out of the equation.

To tap some brass injector bosses is also easy facing the ports.

To make a dual downlet plenum just as easy once you have the flange.

Don't hate me just consider me the devil's advocate......
I'm just asking the obvious questions that one would ask if wanting to buy these or research if there is a market to sell these to...

I don't get it? what are you going to put on the end of these manifolds?

carby turbo is a world of hurt, don't bother

so if it's for injection it will need injector bosses

plus why ask hy-flo to make it if you already have picture of one someone else is making?

plus making the plenum is the hard bit not the runners, so if people can make their own plenum for it i'm sure they can make the runners

plus i don't think there is a large market for this, carby's wont fit on the end and will be hard to support, injection is way more money than most are willing to spend
