on lonnies its an EA electronic brake , the solenoid is inside the pan
stage car in first gear foot on brake , hold trans brake button , take foot off brakes , pedal down build boost , let go of button, hold on!! and be ready to shift 1-2 (or 1-3) real soon
for those on stock shifter make sure you have a detent plate that will prevent accidentally bumping into N , lightning rods dont have that problem
i see you have the TR6. thats good , i personally wouldnt use that brake without some sort of a rev limiter . the 200r4 1st gear is very short and on alky it had better be an ignition limiter like theMSD dis4, bailey 2step or TR6 ignition. you do not want a chip limiter or the limiter in FAST orXFI too that cuts fuel as a rev limiter. the bailey is nice in that you can also use the 2step to limit RPM while building your launch boost and the timing retard to improve spool time
with the 200-r4 i actually like the manually activated stageright brake because you need to bump out of first to release the brake allowing 1st gear shifts automatically after you come off the tbrake, giving some time to shift 2-3. i would see 1-2 shift within 45feet of the line and would manually shift 2-3 around 300 feet
and i hope you have some improvents to the driveshaft and the rear because the transbrake will find the weak links
