The Audi system requires DV's........ NOT BOV's!!!!!!

This topic is probably the largest and most widely covered topic among those with 1.8t and 2.7t engines.

 

BOV gets my vote. HaHa take that everybody else on this audi forum

 

"Ignorance is bliss." ....huh David_K??

 

True that, Mr. Moderator, True that.

 

Hey guys, i was talking to somebody at APR and he told me that instead of buying expensive DV's, the s4 can use teh stock TT valves and work exceptionally. He also said that it is what they use in everycar there. ($33)

 

Very true. They are known as the 710N valves. They have been used quite well by many owners of 1.8t and 2.7t engines. It is a good alternative for those who can't afford or don't want to pay the extra $$ for the Baileys, Forges, etc.

 

that is quiet the difference in price... $66 for a pair, or $318 for Baileys.... difference is practically Short shift kit for the car...
are those 710N really that good? and why in the hell didn't Audi put them on originally?

 

interesting discussion, still can not get what is better..

Here's my take on the issue:

It has come down to a matter of subjectivity now.
The expensive DV's have their merits and the 710N's have their low cost benefit. Some people conclude that you can buy three sets of 710N's for the price of one set of Baileys and thus have two backup sets in case the others fail.

If you are a diehard track racer and you need the best in performance because every ounce of response could mean an additional 0.10 second of ET, then you will argue the Bailey, Forge, or other expensive units are the way to go.

If you are a scientific nerd or just geeky about data, then you might be excited to do all the trials on the DV's out there and come up with something like this report.

This is a long standing argued subject which has many supporters of each and every DV available. I suggest you read as much as you can - all the user comments and data available - then make your own decision based on your gut feelings. To each his own.
