I've never had any problems with my S280 and Whoosh v3, and I make ~370 whp and torque on E40 with my setup @ ~34 PSI.
Car has run bottom 12's in the 1/4 mile with a slipping clutch.
2860 with a V3 is just fine, no sense spending a bunch on something bigger when it's not needed!
You'll blow up the stock engine before you over-power a Whoosh V3.
