well, i went to a local track end of june. i had a less than stellar showing. i could not get any traction because i am running some cheap too skinny tires. 4 runs @ 16 flat with 2.3 60 ft. needless to say i had a few problems. traction was bad as i said earlier. it would spin badly in second gear also. i do now have a 3.55 geared posi in it. it would also power down near the end of the track, just lose power. so after 2 runs like that i began logging my runs on a laptop. my fuel system will do this. what a neat tool to have. i can log air/fuel mixture, rpm, spark, water temp, boost, timing, intake air temp and many other things. it showed me some of the problems i was having.
i have been running the timing very conservative and @ full boost it was set @ 20 also have been running the fuel mixture the same way and had it at 10.75-11 @ full boost. i ended up logging 2 runs.
the next day i took it out and started leaning up the mixture. eventually getting it close to 12 to 1 under full boost. that woke up the motor quite abit. then i started bringing in more timing 1 point at a time and testing. so far i have brought it up to 24 with no signs of pinging. with the timing increase the motor is really starting to wake up.
i am going to get some bigger tires (enough to fill the wheel well) and try again in mid august. tom
