horse power mods!!!

[capturedbyrobots]

Any ways my idea is to make atunedpipe with expansion chamber but add a choke per say behind the exhaust chamger that could be manipulated to breath better as You go throw the rpm range , Even just a gear changer and cable to keep it simple/.
.Imagine a powerband that will take you threw a range of 3000 rpm instead of just 7 or 8'''hundredrpm.
An alternative is to do some testing with a couplesprings and see if you could get this restrictor plate to work automaticaly from the increase/decrease in p[ressure caused from accel'deaccell.v

Has anyone put an intake reed their Happy time?
