There is a A4 around where I live with a BOV he has it mounted between the intercooler and throttle body he cut into the hose there and fabricated some custom flange it works but he is always telling me how he gets horrible gas milage in it

 

Yeah gas mileage will suffer greatly. Hey Imolas4 do you have a website www.imolas4.com?? do you have ko4s? my dads GNX has 2500 original miles and everything is original. if i can steal the keys from him whiles hes sleeping ill meet you halfway and we can terrorize the streets. Straight up!!!.

 

-Grand nasties run 11's pretty easily, they were one of the few cars i was afraid on in my honda. Especially if they had a nice lumpy idle.

-BOV's serve no purpose other than protection from compressor surge, why on earth would you change to one when a good DV will work better. Oh yeah i remember, FnF made that pssft sound cool. Damn ricers, its called function over fashion, not vice versa.

 

Hey, whatever floats your boat. My dad GN is the '84 Grand National eXperiemt. it was an experiemental engine, and it wasnt build as fast as '85 and '86 GN. talk about a sleeper though.

 

Hey i just purchased the HKS SSQ BOV for my 01 A4 and i was wondering if anyone knew what size welding flange adapter i should use, whether it be 50mm or 60mm?

 

Okay well thanks for the advice guys, since most of u seem to hate BOV's what a about a bypass valve...?

 

you need a diverter valve bov's do nothing but bad tihngs to audi's

 

my next mod might be a BOV no joke

 

yea but you are an exception as is tomritt and a few other choice people

 

i just have to find some way to attach it to my charge pipe
