Just wondering, how would the boost machine work with a Revo Stage-2?

Default Just wondering, how would the boost machine work with a Revo Stage-2?

Which is supposed to take the K03's potentials to its limits. Or respectively, how would the BM work with a Revo set at HB-9, which apparently doesn't leave much potential on boost increase?

Any help appreciated...

You'd be better off to dial down the REVO, then bring it back up again with the boost machine. The smoothness of delivery, spike control etc have some good benefits even with high boost software. It's more than about boost! APR/BM guys are running 18-20psi. Anything much above that with a little KO3 and you're probably just cranking out heat, not power...

Default since we're asking about this...

are the revo sp3 and bm the same thing? e.g., do they basically do the same thing, or?...

Default So Steve, can't you just increase boost with both the boost-machine and an SPS-3?

Too much boost = no result? Can't these 2 co-operate?

SPS3 controls (electronically) the Command or requested boost from the ECU through the N75. Boost machine is a line "conditioner" that pneumatically controls the actual wastegate signal..BM can go up, but not down from what the computer is requesting..

Default Answer just above..>>

They work together just fine.

Remember...SPS3 just alters the N75 frequency. The solenoid is relatively slow in responding to boost demand which is the reason for spiking. The BM controls the actual air signal, so clamps it even before the N75 can get control.

Default My boost machine and my Revo (with SPS3) live very well together.

The biggest thing the BM gives you above and beyond Revo is the "instant on" boost, in low throttle situations. As Steve said, the conditioning is nice too, but it shines in the lower boost applications.
