Stock motor + 100LL = ?

[obr]

How much boost can a guy run on 100LL on stock motor WITHOUT headshim on an Apex? Is it the same on the RX-1?

I know alot of guys are running 17lbs on 100LL but that is with the shim, on MCX...

But, if running a completely stock motor, no shim, can you go to 12, or maybe 14 on 100LL?

I wouldn,t go over 12lbs at low elevation.
