Re: cam upgrade for 85' 4ksq
I would not do the exhaust unless yours is ready for replacement anyway.
Unlike the Coupe GT, the 4K quattro has the best exhaust system Audi put on
a normally aspirated motor. This exhaust is worth 5 hp over the Coupe GT.
I use the Schrick 272 cam in my 4kq. with the factory exhaust in place the
car picked up about 10-12 hp at the top end. You won't notice the
improvement though unless you push the motor to the 4000- 6000 rpm range.
Below 3000 rpm there will be slightly less power. Remember a cam doesn't
make horsepower, it is a tool for adjusting the torque curve of a motor to
your driving style and needs.
