getting the 07 ready for track openings
my son matt and i spent last couple of days working on his 07. dropped engine out, redegreed 08 race int. from 110.5 to 108, stk. ex. cam from 106.5 to 104.5 as we we're hitting rev limiter with power still climbing with original setting, will strenghten bottom and midrange and hopefully be all in before limiter now. all valves were within .001 of each other, plugs looked good so tightened up gap for nitrous, dwayne at cycle concepts was helpful in choosing the right clutch and discussing gearing. ordered dragpac with several different spring combinations and 530drz2 drag chain. engine back in almost finished, uping the nitrous jet two sizes, retuning on different fuel and reprogramming nos mini to bring nitrous in quicker at a little higher start percentage. also extended axle slots on adams arm 2 inches, turned the alu. axle blocks around, drilled, retapped for new axle adjusting bolts, looks great and was able to pickup almost 2 inches in wheelbase with chain adjusted. installed new vortex black cat 5 530 rear sprocket also. feel like we have resolved some issues we discovered on our first two nitrous passes. we're looking foward to a good test and tune day and getting dialed in for next year. good racing guys.
