Blowthrough carb prep
I'm curious about EXACTLY what mods have to be performed on a sidedraft carb for it to be workable in a blowthrough application. I was under the impression that it was imperative to have the throttle shaft sealed at both ends, but when reading through Maximum Boost the other day I noticed what seems to be a contradiction to this. The book states that almost all seepage at the throttle shaft is merely annoying and doesn't effect the carb's performance. Did I misread that or what? BTW, I'm using a Dellorto 48mm. Thanks for the help guys.

Info I'd like to know... I'm thinking about ditching my entire shitty EFI system for a blowthough... but ultimately I hope EFI with a standalone would be better... but much more money....

Blowthough carb setups are a thing of the past now as aftermarket EFI has gotten so much cheaper. (and much much better than a blowthrough setup)

Leakage around the throttle shaft is negligable.
