webber carb
Turbo Mini Forums

I am toying with the idea of using a webber on my turbo project, anyone got an idea of if i can get hold of a plenum for these? or will i have to go the custom route?

If i remember right janspeed use to do these as in the yellow bible. But youll probably be better off getting one made.

No Janspeed used a Dellorto.
As regards plenums, it'll be a custom job i'm afraid. I seriously wouldn't bother with a Weber or Dellorto in a blow through install though, stick to the well proven and much easier to tune correctly SU.

don't you have big problems trying to run possitive pressure thought a Webber/Dellorto? I know it can be done with a pull thought turbo.

Ask Jukka. The only one done back to back tests on these.

If you use weber or dellorto in a turbo application you have to update the seals. They are available as the Lotus Esprit turbo used them, but it would be an expensive task.

Only reason i would use a Weber is for Suck Through to get the throatyness, otherwise i would leave well alone, as the lads say theyre meant to be a cowbag to setup.

youll also need the laterplastic floats as the boost/fuel pressure might crush the wafer thin brass ones

after reading your replies and having a scout about on the link from vegard.

Think ill just stick with SU, although go twin if i can

why bother mate?

a single su can do anything you could possible what a carb to do..

"did you know you can toast potato waffles?"

1) Its a WEBER carb i.e. only ONE "B"

2) Its really not worth reinventing the wheel. Single SU has produced in excess of 200bhp.

Would it not be possible to use 2 SU's..?

I drill holes in everything..!

Anything is possible given time effort and money, but has to be weighed up for benefit gained versus time effort and money expended.......

why?

I dont think anyone has tried twin su turbo? Not as far as i know anyway. You can calculate til numbers are coming out of your arse, but the proof is in the pudding. If you can do it try it! It may give decent results??

only way is to have a go, so i may aswell try, if it is successful or not ill let people know.

I did see a weber manifold (maybe in Vizards little yellow book) that you could also fit twin SUs on. They were nice and close and it would be easy to fab a plenum for.
