#1 IMO if it has reg. treaded street tires on the front
go around the water box (when ever feasible)
so you don't drag water to the starting line
back into the water box, get them wet
then move to the forward extreme of the water spot
#2 then;
pump the brakes up to pressure, get the front locked with the line lock
let off the brake peddle, engage the trans in the gear you think or works best
you know your car best, then let em' rip, it's a little trial & error
different rubber compounds & different styles, require different type burnouts
disclaimer;
I also suggest to not do the burnout in the middle of the box, in the puddle
it will sling excessive water into the wheel wells & could drip down onto
or in-front of the rear tires, won't be good either way
IMO it's just a good precaution/practice to take, it won't hurt
just simple logic & experience
(dedicated drag car like a couple of the guys here have
& they usually have speed rated front runners style tires,
low resistance rolling etc. & with very little tread or depth to the tread,
no big deal to drive thru the water, pull out of it & start the burn out,
BUT; it's not a street treaded tire, that holds a shitload of water)
I can't remember if you have a Tremec or (IIRC) a Passon 5 speed
a Passon 855 5 speed has a (direct replacement for 833)
2.56:1 1st, 1.92:1 2nd, 1.40:1 3rd, 1:1 4th & 0.070:1 5th O/D gear
if I read & remember correctly
with the tires wet,
it should be no issues getting them to start spinning
even with a stock-ish 440-6bbl
with a 541cid beast, you plan on having it should be a walk in the park
2nd gear will work too,
just don't let it get away from you,
you don't have to spin it to the moon in a burnout
or bang it off the rev-limiter either
that may be a crowd pleaser but your engine builder will hate it
& then once the smoke crosses the tire surface, you can "usually"
just walk it forward, then good to go...
of course unless;
you find the need to get more heat into the tires
which is a slippery slope when it comes to drag slicks
or how tracks are prepped can affect it too
or especially drag radials you get too hot 'sometimes'
is as bad as not cleaned or cold tires in many cases
the rubber balls up when too hot & it works against you
disclosure;
not all cars, tries/slicks or drag radials or burnouts are equal
a 12 sec. street/strip car, with 450-ish crank HP
with shitty low profile of any make Drag radial with 'little to no sidewalls'
vs
a 8-9-10 second car with 700-900 crank hp
running real bias drag slicks 29" & up, or real radial race slicks
will be different too
that's my experience & my opinions, take it or leave it
find out what works for your specific car, not by committee
