After all, we know what happens when a big auto manufacturer tries to be sneaky with emissions don't we?
The reason for this is to help manufacturers meet strict emission standards and still offer a warranty on their performance-oriented cars. Modification #4 - Downpipesįactory catalytic converters are notoriously restrictive. Where some companies sell front and rear sway bar sets to get the desired results, our bar was designed in conjunction with the factory front sway bar for optimum handling.ĭue to the stiffness of this sway bar, we require the use of our Rear Subframe Reinforcement Brackets to ensure everything stays mounted where it should, and the improved handling of your Audi B5 remains superb. So long understeer! This will help the car to pivot through the corners and remain flat while doing so. Compared to the stock rear sway bar, our bar boasts a 213% increased sway bar rate in the "soft" setting and an impressive 330% over the factory bar in the "stiff" setting. The 034Motorsport Solid Rear Sway Bar is constructed of 25.4mm diameter solid spring steel, and features two different settings to dial in the handling to your preferences. It's alright though, we've got just the answer to help neutralize the handling characteristics of the B5 and lessen body roll through the turns. A stock B5 S4 wants to understeer and plow forward through a corner when pushed to the limit, that's just science. This sort of weight distribution may help when searching for traction in near blizzard conditions, however having all of that dead weight hanging off the front of the car doesn't bode well when canyon carving. The layout of Audi's legendary Quattro drivetrain means that your engine is sitting almost entirely in front of the front axles on a B5 chassis car. They are direct replacements for the factory diverter valves, and are fully serviceable should you ever need to. Constructed from billet aluminum, our valve features a spring and piston design that can handle increased boost pressures for a longer life than the factory units. For a bullet-proof solution however, we recommend upgrading to the 034Motorsport Bypass Valve.

Once a diverter valve has failed, your car will feel like it has gone from 100% to 1% and no longer be able to build boost.Īudi did eventually update their design with the 710N Bypass Valve, using reinforced rubber to withstand higher stress. Factory units are plastic, and use a fragile rubber diaphragm that are prone to ripping once boost levels exceed factory levels. The weakest, or first component to give after an ECU flash is likely to be the diverter valves (aka: bypass valves). Once the boost has been turned up in the form of the Stage 1 tune, this will start to flow significantly more air through the intake tracts of the motor, and push some components beyond what the factory had intended. Modification #2 - Upgraded Diverter Valves

This is the only upgrade you will do for under $500 that will yield gains of 65HP and 87TQ! Be prepared however, because once you feel the newfound power you will be hooked. Don't believe us? See the dyno graph below of a B5 S4 with only a Stage 1 tune and no additional modifications. This simple upgrade will transform the car from docile and dare I say sluggish, to an eager and willing machine that feels as if it should have come this way from the factory.

This software flash can be performed in a matter of minutes through the car's OBD2 port and doesn't require any additional supporting modifications.
I think it's fair to say that if you're looking for the best "bang for your buck" upgrade for your B5 S4, a 2.7T Stage 1 Tune is it. For those looking to study up on Audi's biturbo 2.7T, and learn the basics of the emerging "modern classic" B5 S4, this article looks to provide you with a baseline of the top 6 modifications you can perform and why. Some suggestions are reasonable, addressing maintenance items and troublesome factory parts to improve reliability, while others throw caution to the wind and urge you to jump into upgraded turbos over all else. There's a plethora of information floating around in the web regarding the Do's and Don'ts of modifiying these cars, and sometimes it can be difficult to make sense of it all. Yeah, you read that right, twenty years ago (almost)! Since that time, plenty of aftermarket tuning companies have taken aim at improving the B5 S4 and everything its 2.7T powerplant has to offer.
It's hard to believe the first B5 Audi S4 was rolling off the assembly line at the factory almost 20 years ago.
