a pro turbo engine built correctly with a high cfm turbo will generate well over 4 bar of boost or 56 psi even more wit high rpm motor with nitrous
This isn't a very well phrased question as you could mean how much horsepower does adding a turbocharger produce, or you could mean how much horsepower do you get from replacing a factory wastegate on a turbocharger with an aftermarket one. However, neither of those questions can be answered concisely without specifics of the application.

Pressure in a turbocharger is regulated by various components such as exhaust gas pressure,condition of blower and impeller blades,condition of gas passage on suction and exhaust side,condition of air filters,closing and opening timings of exhaust and inlet valves.

Trouble code P2262 means: Turbocharger (TC) boost pressure not detected
Types of turbochargers Turbochargers are of two types and they are pulse and constant pressure type turbocharger. Pulse type turbocharger: In pulse type turbocharger, the exhaust gas directly enters the turbine side and drives the turbine with the exhaust gas energy. The connection from the exhaust side of an engine is directly connected to the turbine side of a turbo charger. The pipe connections from the exhaust gas towards the turbine side are generally small in length and exhaust grouping is provided to prevent the blowback of gases from one cylinder to another. Constant pressure type turbocharger: In constant pressure type turbocharger, the exhaust gases gets collected in a single exhaust gas reservoir, where the pressure is maintained constant so as to avoid any fluctuation in the exhaust gas energy pressure. The exhaust gas is introduced to the turbine side after maintaining the pressure inside the cylinder. Materials: Turbine and compressor blades: Steel or nickel alloy. Volute casing: cast iron Bearings: steel or gun metal.
The blow-off valve should not be confused with a waste-gate. The waste-gate is a device that by-passes the turbine wheel of the turbocharger, limiting the shaft-speed of the turbocharger. Therefore, limiting the boost (pressure) that the compressor generates and keeping the turbocharger from over-speeding. A blow-off valve is mounted in the intake plumbing between the turbocharger compressor and the throttle plate. The blow-off valve is a second safety measure against the turbocharger over-boosting and damaging the engine. The blow-off valve is more commonly used to keep the turbocharger spinning when the throttle plate is suddenly closed. When the turbocharger is generating maximum boost pressure at full throttle and then the throttle is suddenly closed, compressed air coming from the compressor slams against the throttle, generating extremely high pressures that travel backwards to the compressor stopping the compressor from spinning. When the throttle plate is again opened, the engine must spool the turbocharger shaft again. The effects of this high pressure can also be very damaging to the turbocharger.
boost pressure, as you call it, will not show on gauge,if you have one, while engine is at idle the turbo pressure does not boost but runs all the time according to the revs of engine
A motorcycle turbocharger typically costs between 3000 to 7000 dollars depending on what features are used and what kind of power is needed for your bike.
No it's water cooled, but it is supplied with engine oil pressure for the bearings.
A boost gauge in an internal combustion engine has the role of a pressure gauge. The gauge indicates the manifold's air pressure or a turbocharger or supercharger's boost pressure.
