Audi 80 Turbo

Here is something we are unlikely to repeat any time soon, not because its super rare or exotic. Its just a conversion that in the real world just isn’t done all that much. Rob has taken this Audi 80, and equipped it with a 1.8 20V Turbo engine originating from a Mk4 Golf (or similar). These engines have small turbos that produce a quick spool that translates into a very fun B road toy.

Even though the 20v engine is a fairly compact 4 cylinder, it didn’t leave a lot of room for a downpipe. The space was so tight infact that we used a 2.5″ tube diameter. This will be more than capable of flowing the 350-400bhp that this car is intended to have.

A little cutting, grinding, and welding later we have the downpipe finished. Using our 2D radius bends to give a nice smooth direction change for the exhaust gasses as they exit the turbo via the bolted laser cut flange, and passing through our stainless steel flexi joint.

With the downpipe complete, we can now begin on the rest of the system. We are using 2 silencer boxes to help keep the noise levels down on this Audi. We also make use of the OEM fitting points as they are more than up to the job of supporting the new system, which is likely to be a lot lighter than the long gone OEM exhaust system.

At Walton Motorsport we primarily design our systems for optimum flow. As you may have picked up on, more flow equals more power! Every bend in the system slows the exhaust gasses down and restricts flow. As a result, we only use bends and direction changes when absolutely necessary.

Finishing the system with a 3″ tip directly from the rear silencer. We felt this best suited the overall appearance of the car.

Unfortunatly this car is currently not complete enough to run, so there is no soundclip to accompany this write up. But hopefully Rob will return at some point with a running car.
