Our power to weight ratio is about 6.2:1 with driver.  The car weighs
2175 wet with no ballast.

To keep things in perspective, we have been developing these cars
seriously for about 5 years.  Some of you may remember Mary and I
running our white car(now blue and white) in San Fran region back in
96-97 :)  Long before a cobra was a twinkle in James eyes hee hee hee  

Getting a FFR to this level is somewhat copy and paste now... but that
was after many many years of development.  It included a totally new
rear suspension (IRS) and a total redesign of the front suspensions
ackerman, roll center and SAI.

The original is listed in BP and FFR falls into this class under section
15.11 a
        "Due to the extent of modifications permitted in GT- derived
cars classed within the prepared category, it is possible for a replica
to meet the legality requirements for the corresponding original model
provided the engine, track, and wheelbase remain within allowed specs...
The 10% increase in mim weight does apply to such cars." (somewhat
paraphrased)

In BP, the weight is very high for this car considering its wheelbase...
something like 2750lbs.

We do not fall under NOC "not otherwise classified"  We transfer to AP
based on weight and motor size following BP specs for the original cobra
as stated in Apendix A for AP.  With the minimum weight + 10%  I think
2255 or 2250 depending on if you add the 12 inch wheel penalty before or
after the 10% replica penalty.  Motors over 5.1 add another 200lbs.

This has been confirmed with both Howard Duncan and Doug Gill of SCCA.

Our hope it to gather peoples interest in running FFR's as prepared
cars.  They are just a blast to drive when prepared correctly and as
Chris said not to expensive.  If someone was really creative, I think
one could be done for well below $20K.   I've even mentioned the
possibility to FFR about developing a stripped bare bones car just for
this purpose. Chris and others have also mentioned this. We have about
3500 of these things cruising on the streets of the US.  This year we
will have over 5 drivers running AP in FFR's at the nationals.  Next
year I think we could get 10+ drivers running in AP.  I just hope the
SEB doesn't do anything to kill the apparent momentum we are gaining.
