weber carburettors

Post  gtpswift on Wed Feb 16, 2011 1:50 pm

who has run their GTi engine on weber or similar carburettors, I know its old school but its also cheap (nasty possibly) and different and sounds great and would simplify the justy conversion. I have a matched set of 40's and can get a mainifold easily enough, but was wondering about the ignition side. will the gti ecu run only spark...im guessing not thus a spark only ecu would be required...any thoughts. any advice from anyone whos tried it.
Cheers,
GTP

easyest way would be to use a mk1 dizzy, vacume advance etc
but one of the old racers (hamgar) used a weber setup with the std mk2 dizzy, it had no spark advance but with p+p head and grp a cams it made a handy 135hp @8600
he kept the ecu for fuel cut incase of a crash

Hi JP,

I have been told that Webers are old design.
If you didn't have them, I was going to say use Derollo carbs( spelling mistake me think!) instead.
Bruce aka Hamgar did use std ECU and DCOEs. He did have my mk1 dizzy to play with also.
iirc, he did say he always had engine check light on but it worked OK.
He think he could get more but he was winning his class, he did think he needed to.

Cheers
Atchi
