I keep  a 3.65 for the long tracks and a 3.89 for the short  ones.  At Cal 
Speedway or Willow I too run out of revs (7800) hence the  gearing.  I can't 
imagine you'll ever require a 3.27.

Well  SHORT weekend at Texas World Speedway with CVAR. Friday was test and 
tune day,  I'd paid for the weekend... should have learned my lesson by now...
With  the lovely T50 having a 5th gear, on the LONG straight I was shifting 
into 5th  at the start finish line which carried me well into turn 1A... lots 
of top  end...
Now with the GT6 4 speed gearbox and my 3.89 locked diff, I'm  redlining 
(6000 rpm) AT the start finish line and just taking my foot out of  it.
Bob Kramer says build the car for TWS... I'm just wondering if I should  go 
back to a 3.27 differential. I feel like I have plenty of horsepower, as  I'm 
running 3rd and 4th gear the whole way around...
If I'm not running  terribly hard should I run without a locked diff?  Can 
the welding of a  locked diff be done with the gears in place or should I 
remove 
them?
Or,  should I go back to Quantum and go through the expense of an overdrive 
GT6  tranny and leave the 3.89?

One more question.. I have 175 SU's on the  GT... at about 4000 rpm it's 
leaning out, like hanging there, if I let off the  gas a bit it will catch up.
The carbs were built by Joe Curto with these  specs... 
HS 1 3/4 
metering RF
Float level 3/16
Idle screw 1 turn  In
Mixture Nut 1 1/2 turns out
Jet 1oo
I emailed Joe once asking if I  could purchase some needles that would let 
the car run a little richer, I  think that is what I need but don't know for 
sure...
Probably the wrong  weekend for a query, but I know all of us aren't at the 
Glen, although I got a  really nice tee shirt from the event!

Kindest regards,
Bobby  Whitehead
