RE: [DML] Re: Bolt On Performance.



My problem with all of these "performance improvements" is that 
there is never any data to back them up.  If these things really are
an improvement - prove it.  Put a standard, freshly tuned up car on 
a dyno for a baseline run.  Then make One Change and put the car 
back on the dyno and measure the difference.  Then put the old parts 
back on and put the car back on the dyno.  The first and third runs
should match, the middle run shows the improvement.  

Dave is right - you can't evaluate any new part as a performance 
improvement unless the part being replaced is running at it's optimum
specification.  It's like replacing a 25 year old, flat bald tire 
with a brand new properly inflated tire and claiming that it's 
an absolute performance improvement over the original spec tire.
You aren't comparing to an original spec tire - you are comparing 
to a 25 year old, flat bald tire.

Until there are measurements, it's all snake oil.
