I'm going blow through so need a carb to take pressure.
my inlet manifold will take down draft best, and can be opened out to a maximum of 1.5", 1.75" at a stretch with the adition of a spacer with a tapering hole down the middle.
the obvious option is a metro turbo carb... but 1.75" su is abit phat on a 750cc engine! and they are rather expensive (don't forget this is a ghetto supercharger setup) and would require alot of mods to make it fit the manifold.
next option is a renault 5 turbo carb - solex 32DIS, would bolt strait onto the manifold, but once again they are expensive, and is going to be hard to jet properly...
last option is a box around a 1.5" su, to make it fit i would need to make a 1.5" bore 90degree elbow.
this is clearly the cheapest option, but have any of you guys any experiance of this? i would make a back peice to sit behind the carb when it bolts on, this would have a turbo through it for the fuel line. i would then make 5 sided box to go over that with just a throttle cable passing through the front - or somthing along throse lines. the only problem here is getting a seal around the throttle cable.
so sudgestions and opinions.
