Max Boost level

[milosusa]

Hi to everybody, I am new to Arctic cat Z1 engine, actually using them in RZR buggies, but really like to know more about them.
Have a couple question about boost level those engine can run on pump gas and race gas.
What is maximum PSI which could be run on the stock thickness head gasket and head studs on pump gas ?
Same as above, but with thicker head gasket installed ?
And what will be max PSI boost on those set up, but with the trace gas VP110 ?
And one more, did ECU automatically rise the boost to compensate for the elevation changes due the information from the ambient pressure sensor be different ?
Any help will be appreciated.

What elevations you riding? And yes it will compensate the boost levels for different elevations.

Thanks Snowmow, elevation from sea level (mostly ) up to 5000 ' .

don't know what the max boost is at that level. I ride much higher: 8000-13000ft. I know at 11000 ft I seen 32+ psi on the boost gauge on my 2012 1100 with the EVO BC275.

Just curious, Evo BC275 is a reprogrammed ECU ? It is on the pump gas ?

Yes. Reprogrammed..... The 275 is a 100 octane tune. The 250 tune is 91 octane.
