B5 S4 Upgraded 710N Diverter Valve Install

[@JakeB5]

Note: I did actually install the diverter valves in the wrong orientation, and it does make a difference! Don't make the same mistake as I did and put them in the stock orientation!

Jake, I really love and appreciate your mistakes. NOT because I want to laugh at you, but because this humanizes you. As you know almost 100% of KZbinrs will make a video about how awesome this, and that is, within their lives, While cutting out, or editing their mistakes. You on the other hand, are generous(I use that term loosely) enough to include your mishaps. I commend you, Sir. Best of luck in the future, regarding the ins and outs of this beautiful Beast of a car. Please, do not be shy about making videos!!

[@JakeB5]

Thank you!!

Nice, I never knew about the difference in the 2 diverter valves. I’ll have to do this upgrade.

[@JakeB5]

Yeah the stock ones usually go out above stage 1 boost levels, and sometimes even stock boost levels. Good preventative maintenance to replace them

[@eibbernda4885]

love your videos! I am thinking about buying a Audi s4 b5 myself and was wondering if you have had any problems on ur car? 10 things you like the most and hate the most video?

[@JakeB5]

Great idea! I'll see what I can do!

[@TheDonkDonk420]

Problem number one, be prepared to dump $3000 into the first year for repairs. They are extremely expensive and are a pain in the butt to repair... sometimes I wish I bought some asian car lol

[@eibbernda4885]

@@TheDonkDonk420 what should i look for when buying a Audi s4 b5 to avoid those costs?

[@TheDonkDonk420]

Eibbernda there’s no way to avoid it with a b5, each car has issues one way or another even if it’s well maintained. All the big repairs start to happen around 140k miles. Just make sure to have a lot of extra money after you buy one lol it’s the perfect love/hate car relationship 😂

[@JakeB5]

@@eibbernda4885 The car isn't really that bad cost wise for maintenance, if you do the work yourself. I would try picking up a stock lower milage one, because these cars are actually pretty good reliability wise if you take care of it without doing any mods to it. Once you start modding, especially when increasing the boost levels, thats when the issues start. Most of the maintenance cost is due to the stock turbos failing. If you warm up before you rip it, and cool down after, and do proper maintenance, the turbos should last quite a while.

[@skyguy1988]

wait...so when installing these, the vaccum line attachments point UPWARDS, not sideways towards the throttle body like the stock ones did? O.o pls answer! i just installed these and thought you install them like the stock ones were positioned, with the nipples with the lines on it sideways. do these ones have to be pointed UP?

[@skyguy1988]

please answer! does it matter which way it's pointed?!

[@JakeB5]

Sorry man! I don't believe that it actually matters which way you install them, all the Diverter valve is a valve that allows the passage of air when a vacuum is applied onto the valve, and it doesn't matter the orientation. I actually didn't even noticed I put them on differently from stock, and they are operating totally fine in the way that I installed them.

[@skyguy1988]

@@JakeB5 i experiment a lot with this stuff. putting them the factory way makes the factories boost weirdo...with these 710ns. im not sure if they 710b diverter valves need to be installed stem up ? but the boost was a bit smoother when they were installed like you have them here....very odd. maybe 710ns are diff?

[@snaggletoof1927]

BPVs should be installed with the piston/vaccuum connector being horizontal (how the original ones were mounted at the start of the video).

[@activemonkey7325]

Running it "backwards" like the 710N's in the video makes it so the dv spring is holding back the boost pressure during acceleration. Running it the normal "stock" way, the dv will naturally want to be closed, and only opens from the vacuum line signal when you let off the throttle for shifting. I don't know for sure, but I believe running it backwards makes a louder noise is because it is effectively dumping the air faster than the normal position. So in a sense, it may actually be better to run it backwards. The only problematic part in running it backwards, is that you need to have your spring tension high enough, so the boost pressure doesn't open the valve by itself.
