Hi again.
I shorted the exhaust elbow to 1-2 cm and drilled the two holes in the silencer like AOA (but without shorting the tailpipe) . Now, the resonance effect is between +- 7500 - 8500 rpm (from 6000). Its cool, but a little "problem" is that from 0 to +-7500 rpm the torque is too weak :(. So above 7500 rpm is the real "turbo boost" effect
.
I thought that the torque in low rpm doesn't be sooooo weak.
Is there any possibility to get out this torque hole? (now is this: zero power, zero power...full power
and I want: zero power, more power...full power)
Have the shorting the tailpipe any effect on this? Or doesn't this opening of exhaust too much for 60/2 cyllinder?
My setup is 60/2 and I have adjusted the exhaust window from 31 mm to 29 mm (and reduced cyllinder head) and my ignition timing is 1.6 mm gefore top dead center.
Or should be more on less in this setup?
Thanks!
