But is it? The turbo in a drawthrough doesnt 'drag' the mixture through the carb does it?

It can do. They work under atmospheric pressure fuel push. A turbo gives you vacuum pull.
As you climb rpm on na the 'scavenge' effect draws air in at a constant increasing rate iirc
Boosted engines draw air at a higher rate as boost increases. Creating a vacuum pull

Ok, that makes sense to me, though my head is starting to hurt...

You'll have to inspect the turbo compressor
Could say you'll run lean but you can't 100% blame pooling for it. Too many variables

Mine too man mine too. I dont do explaining thingsOk, that makes sense to me, though my head is starting to hurt...
I've probably done every job except mechanic so I'm just learning.....and that seems to get harder as you get older!!

Not too big I'll find one you can use as referencedont be sorry its great to have somebody to tell me all this ! swirl tank it is with this idea
I miss the simplicity of the K10. Everyone thinks I'm crazy cos I get excited at old cars and think most new cars are meh!

Ade from what i see you know a lot , plus , im 18 and i see no attraction to all my friends golfs , bmws and civics , no ECU all the way
I like to research stuff.....even if I don't actually achieve anything
The small nipple should be at the bottom.
The bottom pipe is in
The top pipe is out
Bottom should be a bowl shape. Not too big at the top
Its pretty but it still looks like a condensor to me

Thanks for that picture , my only concer would be if the out put is higher than the input il have to find another way to raise the carb higher than the turbo , thanks a million chaps your educating me more than i have been all year lol speaking of im also out , more exams tomorrrow , thanks again for your help !

When I was first told by an old boy I thought he was having me on. The inside of those things aren't smooth so they cause turbulence which in turn atomises fuel.Sorry but I'm yet to be convinced
Thats why we port polish to create smooth flow but leave very small amount of a coarse surface (smooth to touch) above the inlet valve. For last minute atomisation before entering the combustion chamber
You dont have to fully atomise fuel but it burns more efficiently (more power) when it is
Ok, but I'm still not gonna fit a swirl pot when I build mine
Cheap and simple.....like me

Never said you have toOk, but I'm still not gonna fit a swirl pot when I build mine
just helpsI think it's purely down to the fact that most cars are fuel injected tbh.Good point ! Just wonder why more dont go for this set up in that case ! Better not think about this too much or might get second thoughts

You tube draw thru turbo and theres some cool videos but i found one or two of a vw golf EFI running draw thru ?
baffles me i would have sworn it wouldnt of worked with EFI, i feel way more confident about this set up , it works its just old technology apearently some old mustangs ran it standard from factory
OP
OP
No i dont believeDo you believe for one second with the research I've done in this that I haven't checked out you tube?
i was just saying if it can be done with EFI , and came factory standard at one stage , it cant be to bad
OP
OP
If ade doesn't , i still am
! Have turbo manifold and MA12 head sourced just need collecting , purchase a turbo , make a few flanges and set it up ! And adress timing issue

Have you seen this before ? No ,Just seen the vid, it just begs the question....why?
Is this a unique setup ? Yes
Is it drivable ? Yes
Why do it ? Because. Its unique !

Haha director. I feel bad he put all that work in to not follow it through
Well the obvious is a dump valve. They always go between inlet and turbo. So the pressure can be "dumped" and not backing through the turbo. Not dumping pressure causes turbo flutter
Its more essential for you as your carb is right there
