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?

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

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

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

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.

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

hey i finish the first prototype drawing of the castings

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

Here is the modified one I did on photoshop just need to be a tad shorter so 2 into 1 blend happen a little earlier of smother closer to the top. Also top should be tapered closer to the pipe to weld on so there are no discrepancies with flow and made a tad wider on the main inlet. So just a few mods.
