Track Results For 2006

Below is the spread sheet that we will be using for collecting data from the testing.  The goal is to change one variable at a time to see what impact it has on the various time and speed measurements taken by the track.

Cylinder Head Flow Results 

Here's a graph of the head flow data.  The heads are AFR 205cc Castings.  The Part number is 145, not 1450.  AFR specified the 145 is either a custom port or an as cast head that was ported elsewhere.  I bought them from another racer unused, never bolted on.  Regardless, as shown by the graph they flow better than a typical AFR 205cc out of the box and yes the runners were cc'd and they are 205 cc's with a 58cc chamber.  The peak flow number on the intake was 321cfm @ .650" lift.  

 Compression Ratio Comparison

Here is a comparison between the 2005 combination and this years (2006) combination.  This data sheet shows the difference in static and dynamic compression between 2005 and 2006.  The graph at the lower right is the 9th pull on an engine dyno from the 2005 set-up .  533 Horsepower and 449 LB-FT of torque, not too bad for a 10.46:1 pump gas engine.  The jetting noted at the top of the graph may seem a bit excessive, and it should, but it is due to the tune of the carb being setup for one fuel and using another.  It was setup for a fuel specific gravity of .760 and the fuel used on the dyno had a specific gravity of .714, which caused the need for increased jetting.  After calculating the static and dynamic compression ratio of this years set-up, there should definately be a significant improvement in both ET and MPH.
