Have a search, there is a pic (I think by Turbo Dave) that shows how to connect it up.

i have searched high and low... but didnt find what i was looking for.. i did find one pic that helped me make the conections already made in the pic, but i still dont know what to do with the rest.. any help is much apreciated.

thanks

your a star mate.. i had already found the first threed, but the second one is much better...

althought i still cant see where the outlet, thats outlined in yellow in my pic, goes.. is it for the wastegate?

The yellow connection is the Vac advance for the Dizzy

great... thanks mate.

hi everyone, i know this is an old thread, but i have a question(probably a stupid one) is there a reason why i cant take the vac feed for my dump valve from the outlet with the orrange circle in the pic? i ask this because i noticed a carb spacer on mini spares with a niple for this purpose and that sits just a bit in front of this outlet, and since there is nothing between the spacer and the part where the oullet is, its seems logical to me... but what do i know...

as long as its on the engine side of the butterfly then yes, it should be fine.

133.5 bhp 123 lb torque 116mph @6640rpm 9.5psi
Shakespear RWYB 14.995 91.83mph

thats what i thought... but thought i would confirm as i have never seen any body say that its possible....

No you can't.

I can't remember the exact reason, but this feed is not just a straight hole to the manifold side of the butterfly.

You'd need to check the HIF44 but on the HIF38 that take off is
_definitely_ not on the engine side of the butterfly when the
throttle's closed.



Nial.

hi guys...

i just had the carb off, and this outlet on the hiff44 is on the mani side of the butterfly...at least from what i can see...

but maybe its like will h said, the outlet is on the maniside, but maybe its not a straight hole down, (didnt check this)

It is just on the manifold side of the butterfly on an HIF44 (I've just looked at one too)

On a lot of SUs it is neither before or after but right in line with the butterfly (when shut) to cover the hole.

In this case I would say the size is the issue - it's only meant to operate a small diaphragm in the dizzy quite slowly.

Dump valves usually use 4mm or sometimes even 6mm signal lines as they are meant to operate quickly, this connection is less than 2mm.

Schrödinger's cat - so which one am I ???

oh ok... thanks for your insight rod s... i gues there is no harming in trying it out and seeing how the dump valve works then?
