Comments on Run #:
1. Little rusty since last time I went to the drag strip. Did a
long burn out and crossed the staged line. Smoke were
everywhere. My stock tires were nicely clean and warmed.
Spectators were like "what the H*ll a lexus doing on the strip"
After the burn out, they know what is coming next. The Reaction
Time (R/T) is pretty. .500 sec would be optimum. Over all the RT
is not bad. 60 foot time is terrible. 2.438 seconds. That
signified that traction is a problem or the launching rpm is too
low. If I can get my 60' time to 2.0 sec, that will reduce half
second off my ET. The terminal speed is very good. Remember,
this is 1/8 mile very short.
2. Tunning my methanol injection to come earlier. The first run,
I did not see the activation of the methanol system until the
end of the race. It was set at 8 to 8.5 psi. lowered to 7.5 to
8.0 psi. ET was better, but my terminal speed was lower than the
first run. This is due to that I start to brake before i cross
the finished line. The spectators is getting the messege that
this lexus is fast and its a sleeper.
3. I continue to lower my methanol activation to 6.5 psi. My RT
got better along with my 60' time, however, its still
unacceptable for 2.366 sec. The final ET for run #3 is 9.267
with 81.38 mph. Run #3 i power brake and idle at 2500 rpm. If I
launch at 3100 rpm with slick, this will be a jaw dropping
The car felt very strong from launch to finished. 1/8 mile track
is just too short for mid to high rpm car. Over all, I think
people give a new level of respect with modified Lexus LS400. I
hope you guys should take your car out to the track and have
Next time on the track, I would like to mount on some slicks in
a quarter mile track.
New Stage II dyno sheet and 1/4
mile run will be available soon. Stay tune for eyes
