RE: cam upgrade for 85' 4ksq

["PAT MARTIN" <MARDKINS@classic.msn.com>]

I would disagree with this.  I put the 2 1/2" system on my car and it really 
helped.  Big power gain up top and no loss at the bottom.  Better yet the 
throttle response was much better.
The coupe vs 4kq difference is the manifold more than anything.

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.
