<DIV>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.</DIV>

style="BACKGROUND-COLOR: transparent" face=Arial color=#000000 size=2>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...<BR>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...<BR>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.<BR>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...<BR>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?<BR>Or,
should I go back to Quantum and go through the expense of an overdrive GT6
tranny and leave the 3.89?<BR><BR>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.<BR>The carbs were built by Joe Curto with these
specs... <BR>HS 1 3/4 <BR>metering RF<BR>Float level 3/16<BR>Idle screw 1 turn
In<BR>Mixture Nut 1 1/2 turns out<BR>Jet 1oo<BR>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...<BR>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!<BR><BR>Kindest regards,<BR>Bobby
