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 result.
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 fun.
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 tuned for eyes popping-jaw draw dropping results!
