going of a 5min sedan run I evaluate my run before looking at the data. Did I carry good corner speed with the car setup and if I didn’t was there enough punch to get me out of the corners since I didn’t carry good speed. Also how was it down the straight? Did I top out too early or was it still accelerating when it was time to let off? This is signs of under/over gearing. I then go to the date logger and look at the graph and track the trends and determine if I can improve with a gearing change of adjusting can timing. Sometimes can adjustment a few degrees equals a huge jump going up or down. Too much timing makes the motor fast but bring in heat and gearing down doesn’t always help find that happy medium. If the motor has a strong rotor I have found that lower can timing and proper gearing to get that top end speed back will be just as fast as the higher timed motor but not run as hot or experience motor fade that we’ve seen locally from the Team Powers V5s and V6. The V6 came out late and only team guys had them for the Roar Nats but had that motor come out earlier in the year when it was hotter I bet the message boards would have been lit up with unhappy customers because guys crank the timing to the moon and ridiculous gearing. Team guys still had issues at the nats cranking timing from what I heard.
This is what has been working for me and I’m no factory type driver but I have been doing okay locally club racing. Also getting the data after a run is also similar to your testing under load as that vehicle is the load for me. Testing on my bench is my starting point and the main thing I get out of it is that I can always get the same can timing on a motor after disassembly and it shows me how a motor is doing over time ….ie rotor fade, sensor status. I’m not Jim Dieter by any means……just sharing what’s kept me competitive out here in Nor-Cal.
TICK, TICK, BOOM …………hahahahaha
