In real life do the drivers change down to 3rd to get out of
the turns at Martinsville. I find that to set 4th so I'm not
over-reving at the end of the straights the engine is getting
right down thru the turns and I feel that I can get back up to
pace as quick if I stay in 4th.

No. They use a gear ratio low enough to pull the rpms through the corners
and then are near,or at, red-line at the end of the straights. The only
time they change gears on an oval is on re-starts and pit stops.

Eddie,
Not true on all ovals. Drivers at Pocono will downshift heading into 3.
With that execption, you're 100% correct.

Incidentally, the Jerico transmission is now being employed at several
tracks (not just Pocono anymore), and some teams are counting on it
exclusively for an entire season.

Hmmm.... I guess you don't define Pocono as an oval :-)
I think the reason they don't do it at Martinsville is that they
have enough power at 90 mph to break the rear end loose coming off the
corner in 4th and have to feather the throttle anyway. So - no benefit to
shifting. 150 mph at Pocono is a different story.

"That's restrict plate racing."
BTW, real life drivers don't shift down at Martinsville.

Except that most teams now use a Jehrico transmission, where a clutch is
not necessary for shifting. The gears simply fall into place.
The extra horsepower simply isn't needed. It's hard enough to keep the
car straight with the spped coming out of turns in fourth. Wear and
tear on the transmission is, I'm sure, a factor also.

You are right. Pocono slipped my mind(I am kind of an old fart and
mind-slipping is a common problem with me). I kinda put Pocono into its own
little category anyway. It is an oval, with road course characteristics.
Thanks for the correction anyway, Tom.

Some of the drivers prefer to use the overdrive gear both on the main
straight, and the Long Pond straight (the stretch between turns 1
and 2). Rusty Wallace does this, as well as some others.
Then again, others employ the method above--using the overdrive gear
only on the main straight.
One year at the Brickyard, Mark Martin tried shifting on the long
straights, but abandoned the idea the next year. So Pocono is the only
"oval" where the drivers shift during a lap.

The clutch is never *needed* for shifting the Jehrico or Richmond
transmissions, nor is it *needed* to shift your street car. (Except
shifting into first from a dead stop.)
The only purpose the clutch serves is to take up slight mismatches in
RPM between the mainshaft and layshaft in the transmission. The reason
it's easier on the Jehrico is that the dog gears are more widely
spaced and are tolerant of a little more mismatch without rejecting
the gear change and/or breaking.
If you do it right, you can shift a street car without the clutch...
