Re: blow through carby accesories
have you though much about blowing through a 465?? 465`s are vac sec carbs, you will not have a hope in hell in opening vacum scondarys when under boost without a few mods.
however i have done it but it wasnt too successful, i had to drill and tap the top housing and run a hose to the intake before the turbo, but then the secondarys would open way too early and cause a huge flat spot (too much vacume). i mucked around with different springs and ended up putting about 4 springs in there at once to try and a reasonable opening point.
Cut a long story short vac sec carbs arent real successful for blow throughs use a double pumper instead.
