I wanted to see those peoples with Carb what kind of mods have you done to get enough fresh air directly to it?

 

intercooler....



but before the turbo setup... i ran some flex pipe from the top of the carb down in front of the radiator. used a k&n filter. didn't notice any difference, so i went back to my racing beat open canister which gave me back my throttle response. i say humbug to these cold air intake setups on carb'd 12a's. get a heat shield over the header and do more for getting hot air OUT of the engine bay. that's your best bet overall

 

heres mine, an old and crusty pic



thats it on my old S3 and the pic speakes for its self so i won't ramble on about it, except that i've got another car now and i plan on modifing the air box further

 

How did that huge intake hose work for you? and where did it connect to?

 

there's a write up somewhere on how to do it. search for "home depot intake"

you could also:
get a carb hat and run piping in front of the rad. and have a K&N there
use the rb intake
use the stock air filter assembly with a K&N in there with piping in front of rad.
use a headlight cover scoop and run piping there- use a heat shield
hood scoop and filter right there- expensive
Use stock airbox and take filter out then piping in front of rad, K&N there- Maybe?
