I had a dyno run with the mbc, sports exhaust, TBTC rework, turbo silencer removed, K&N funnel mod. Can't remember the numbers.

But HP is a bit silly. Unless you are wide open throttle at real high RPM's you are not at peak HP.

With the MBC you now have boost and torque comming on much sooner which is a big improvement. You have boost long before the engines rated at 200hp in their stock trim. And you have lots of power in the 1st two gears. So as far as spirited street driving goes, you have some real advantages.

Note that the modified ECU's also still have the same BPC valve and the inherent boost delay of a bleeder valve. So in many aspects your vehcile with the MBC is superior.

A HP fixation is of little value. HP is measured on a dyno and is quazi steady state and that ignores boost delay and reponsiveness.

For you to get more HP with your vehicle, you have to work to eliminate some of the restictions in the intake and exhaust that cause boost to drop off at high RPMs (CFMs). The stuff in deans<underscore>list on the NG900 BB is a good reference. The Viggen IC retrofit really makes a big difference too. With the MBC the pressure tap that feeds the MBC is often at the turbo. Thats quick and dirty, but causes boost droop at higher RPMs. There are all kinds of issues involving the pressure tap location. I will not go into detail here.

Glad that you are happy with your results. Now that you have 'boost fever', whats next?
