B6.4D VS B7D Speed Control and Motor Changes
- Less Timing in the B7D. I took some of the TC knowledge gained and backed the timing off to where the TC guys are running their stuff, so around the 40-44 mark. This car creates a great amount of corner speed, and getting the motor in a more efficient RPM range greatly improves the perforamce of the motor. I put the motor back in what I call the "efficiency" point (most amount of KV and RPM while pulling the least amount of ampdraw underload) theirs always a little bit of wiggle room to run the timing higher, but that can cause heat, fade, rotors tend to fade around the 150-60° so keeping everything internally cool is key. If your motor is running 150 externally, your rotor is probably hotter.
- Fan Shrouds, 1up Racing makes this really cool fan shroud that fits on our fan, and the other popular fans, it requires a little bit of trimming for the B7, but nothing a pair of lexan siscors couldn't take care of.
- Wiring the Fan Direct to your Speedo Control, soldering, I know scary. But this will dramatically will make your motor run cool, I went from running 160, to 120-130 after multiple 5-10 minute runs.
- Drive Frequency, I felt I was lacking a little "snap" out of my car from the .4D and lowering that range from 2-32 to 2-12 really helped make the power delivery feel more direct, so if you ran your frequency higher you can try less to get a wee bit of snap out of it.
If anyone has any questions, concernss more then happy to help, when your running this thing and are thinking about power and have some sort of touring car knowledge, base it off of what you'd set your touring car motors to, then adjust accordingly. Hope this info is helpful! |
