Went to the local carpet track for some laps and just working on lap times. They added a huge and amazing drivers stand and added the timing system to the carpet track. Next time I'm down I will get my name and class into the system. First thing was the pinion. The pinion backed out but was still in the car so I got that all patched up. I am still running the 20 tooth pinion and the motor is still having some heat problems. I tried to fit a 16 in but it wouldn't fit due to the motor mounts sliding back. So the lowest pinion I could use in the buggy is probably a 20 or 19. Next was battery heat. Battery was getting warm and puffy after each run. Today I took a look at them and they are not puffy anymore and IRs are still great/ok. Should have a few more runs on them before I should get new batteries. Next was the front shock. I didn't break the shock, what happened was the screw for the piston backed out, piston came off and the shaft came out. I didn't bring any oils and I didn't want to dig into a shock there at the track so I took one off the slash and put it on the buggy. Didn't fit well but it worked. If it works, it works. I did let my dad drive the buggy aswell, he isn't a great or fast driver like I am. But I think he liked how it drove and the set up and all. Looks like they are still expanding the carpet track and making layout changes with expanding the track. They should be having some mini b/t racing and hopefully some 1/10 racing soon in the next couple of weeks. I did bring the slash but the slash had wayy to much traction and parachuted over the jumps. And racing the slash isn't probably the best idea so I will only be racing the buggy and the mini b if it is running. I had an average of about a 13 second lap after I got used to the car and track layout for the day.
Tonight:
I analyzed the batteries and they look fine now. Next time at the track I will let the battery cool down first before recharging or store charging. Currently I am charging at 10 amps. I might charge at 1C (6.1) just to see how they are. IRs are still great/ok. Should be able to get a few more runs with them. Once they get bad I will discharge them and not take the risk of a fire or pop.
Also tonight and tomorrow after school I will be rebuilding the shocks. I am currently applying the carpet set up (from the B74.1 high traction carpet and turf kit) I am putting 50wt oil out front and 35wt in the rear for the shocks (all Associated/Factory Team oil) I am going to get 15k oil for the front and rear diffs. I think I will stay with 200k in the center diff and move up to 500k if needed. I also changed the shock positions on the suspension arm and camber link positions on the shock tower. I will also be getting a variety of different springs just to experiment. I will also be getting a RPM camber gauge and a toe gauge if they make one, and a ride height gauge. My uncle has a temp gun so I will see if I can use that for the motor and batteries.
For the motor heat problem: Would it be best to gear down to the 72 tooth spur? Currently running the dirt kit set up 78 tooth spur.
So far all if looking good. Will be at the track again in the next few weekends since there is a some car shows going on around the area. Also the MD auto show.
Here are the lap times for Saturday and IRs of the batteries.
