That sounds like a rather high gearing with a helix with a 52 start angle. I don't understand how you can have 5300 engagement even with 5,5 in heel. Something might be binding, for comparison, my srx engages a 4200 with 5,2 gram in heel.
They are notch for racing 660 ...im just not sure if its high gearing or fuel issue ..it does torque alots with the heel clicker

WHat are you running for a primary spring? Sec spring and preload? Sounds like your upshifting too fast on launch.

For 660 I would be on. 21 top. But clutching sounds too like it overloads the motor until it builds rpm.
Its sounds like it ..ill try a shallower helix just for fun and see if the bog goes away ...
Im sure mr viper or tony could chime something about it ����

Just going over Mr. Vipers H/C tips ..... a 34 or 36 finish works well.
It work awsome on top end ...only have trouble out of the gate ..bog went u punch the gaz ..not sure if its over gear or lean pilot ...i try to open up the pilot 3 turn 3.5 and same result ...ill go test with a shallower start angle
Did some check with a shallower helix ....bog is almost gone ...sled hook alot...will change gear for lower ratio ��

Up your pilots to 50 that cleared my bog when using heel clickers
