Warning about dragrace starts with torque converter
For those of you who go to the drag strip and have an SSR with automatic transmission, not the temperature warning for the torque converter in the following quote off a website that sells dragracing equipment:
"Stage control or starting line control cylinder and valve kit.
This is very useful for not only *DYO cars but class cars as well.
For DYO race cars it allows you to stage the car at idle with the throttle pedal all the way open. The valve opens the throttle wide open once the transbrake is released, then just before the delay in the box releases the engine is at the chip limit set in the MSD. This does several things. One it prevents someone from burning you down on the start line. This is not so much engine temperature but trans temperature. We have observed the temperature of the fluid coming out of the converter while at stage rpm will skyrocket from 160F to 280F in less than 2 seconds. This is not only hard on the converter and trans but causes inconsistency in the vehicle elapsed time. Neither of which is a good thing. The solenoid powers the cylinder in both directions. When you activate the unit the throttle pedal goes to the floor and the car continues to idle. When you release the unit the throttle pedal is already on the floor held there now by your foot and the cylinder is powered in the other direction to open the throttle. By installing a optional bleed valve you can regulate how quick the cylinder will open."
You've been warned . . .
This is why I NEVER use that "foot on the brake while revving engine up" technique.
