what is the best way to Launch to keep consistent ets. do you worry more about leaving at the same boost all the time or rpms

SignUp Now!Transbrake will give you consistant launches.
without a two step or a boost limiter the only way to be consistenst is if you watch the boost gauge or watch a tach or develop a feel for it or dont build anything and drop the accelerator when the light goes green (well a little before then) , you probably wont set any et records but youll be consistent

so why do you need a transbrake to do that if your brakes hold or your not trying to build a whole lotta boost (or none) ?
tbrake will allow you to hold more and possible cut a quicker 60'... but he didn't ask about faster he asked about consistent , you can be consistent leaving at 0psi
if your tires are spinning work on the suspension , better tires , air pressure (in tires or airbags if you got them), or leave with less boost
if boost is creeping fix it
dont try for a killer 60 if there's a chance your tires will roll before you're ready to go or so much that the tires will spin as soon as you leave
save the bonzia 60s for test and tune when you want to impress your friends.
you can run less boost ya know and dial back the time on your window, its not heads up race to the finish line.. its a race to the time you write on the window
stage the same position at the beams each time
leave at the same boost
you still need to catch the lights good so focus on the tree and cut a good RT
shift at same time (or let the trans do it )
run same boost every pass
and if everything on the car stays together it should be consistent keeping in mind temps can change during a day at the track so you need to adjust a little
on my footbrake car (the87) i know that the point where i start to lift the fender is at the point of my converter stall 2750 and 0psi , so thats my build point no gauges no chance of rolling , have an electronic controller (msbc-1) for launch and boost but havent used the launch feature yet but it works great at boost control with an external gate DP, leave it in D and go
my 86 i have been using same electronic boost control (msbc-1) for launch and run with a tbrake so i could hold the boost i needed to leave hard , 60' have be within hundreths each time
used to run a two step(MSD dis4) that cuts the ignition back to hold an rpm they had troubles with wastespark ign random cutout and stock type chips , if you have fast they work fine . when i could get a clean leave it was consistent but there were times if i stayed on the two step too long the car would drop rpm during the stutter and 60 would fall from expected
using an indash tach (gnx sytle gauges ) for shift points since i shoot for 5800 shifts , and a shift lite
I dont see where you guys want consistant et's while test and tuneing. If your changing stuff you wont have them. Also if you racing on a reg race night aroung here you cant use trans brakes in the foot brake class, and pro will get that rearend haded to you because they are using delay boxes.
