Testing Transbrake on the street
I just put a C4 with a Transbrake in my 04 Mach1. It has a MMR stroker,
stage 2 port and polish heads with a custom grind cam. D1 procharged and
meth injected, dual gt fuel pumps with 80lb injectors. Exhaust is SLP loudmouth with x-pipe no cats.
Trans brake launch
after setting carb on fire then staging with fuel pump off final get to go.
1.46 short time 10.51 @ 127.88 short shift into second.
car gets just as good of short times foot braking on this day had a 1,44,
1,45, 1.44. 1.44 1.42 foot brake and 1.46 T brake and an aborted 2.0 hard
right T brake launch.
Trans-Brake lesson 101 - Stephan Racing
Rob Stephan shows us how well a trans-brake can benefit a turbocharged car at building Boost on the startline. The Holden VL Calais
RB30 turbo hasn't been out for quite
some time but has recently undergone the switch to a Powerglide
In drag racing, a transbrake is a mechanism that selectively places the
transmission in first and reverse gears simultaneously, effectively holding
the race car stationary as if the foot brake was applied. The transbrake is
activated by the driver by applying electrical current to a solenoid at the
transmission. With the transbrake engaged (transmission locked), the engine
throttle can be increased to any position (opening) in preparation for
launch without the race driver worrying about the car creeping forward.
Milliseconds before the green light illuminates on the Tree the transbrake
is released (by the driver releasing an electrical switch or by a delay box
"timing out" originally triggered by the driver releasing an electrical
switch) and the car launches forward, its engine already in the higher
power band and the transmission already in low gear.
