[V8Vairs] 4.56:1 diff explained

[GnKHOFFMAN at aol.com]

Wow, a double test drive.  I think he really likes the V8 Vairs (of  course 
all of us come up with multiple reasons for driving them as much as  
possible).

Paul, is your 283 the aluminum block car?  If so, I would keep it  as is; 
it is totally unique (of course all our cars are built to different  
purposes).

Let us know how the second test goes.

The tach  I installed for the CPG testing was set to read a six cylinder 
engine.   Totally my error.  Move the slide switch on the back of the tach to 
"8"  and voilla!...my diff is back to a 3.55.

Frank " the professor"  Parker was thinking about what might be going on 
with the car in the middle of  the night, did the math in his head and emailed 
the correct problem and  solution. Frank came over with the right equipment 
to verify the  tach's accuracy across the range. It is now right on the 
money.   Thank you once again Frank.

I now think the Corsa tach, if I  can get it to work properly, will be just 
fine.  6K is plenty for  me. 

Don's deadline for the article is  today.  He is off to Paris for the auto 
show tomorrow and will be  back Saturday.  He wants to retest the car on 
Sunday.  During  the first test he shifted at the indicated 7.5K redline which 
in reality  was about 6K.  He wants to retest at an actual 7 or 7.5K.  6K in 
the  car without an engine cover sounds like 10k. The numbers should  
improve. My only hope is the whole thing stays  together.

I also want to thank all who took the time to  respond.  I am truly one who 
is "getting by with a llttle help from from  my  friends."
