Application: BMW M140i, M240i, 340i, 440i (B58 Engine)
Building on the massive success of over 1,700 X-Series units sold in the Ford EcoBoost market, Pumaspeed has brought its legendary X-Series technology to the BMW tuning world. The X49R is the ultimate upgrade for the B58 platform, designed for drivers who want massive power without sacrificing the driving experience.
Many aftermarket turbos are obsessed with peak power numbers, resulting in significant lag and poor daily drivability. The X49R takes a smarter approach:
OEM+ Drivability: We prioritized spool times to give you a responsive, factory-like feel.
Devastating Early Spool: Gut-wrenching torque available as low as the stock turbo.
Massive Power: Capable of 600whp with the correct supporting mods.
If you are happy with a rapid 550-600bhp and want a car that is responsive on the street with zero lag, look no further than the X-Series.
Max Potential: 650bhp
100-200kph (62-124mph): Proven fast times recorded via Dragy.
Spool: Matches stock turbo characteristics for instant throttle response.
To achieve the advertised power figures, specific fueling upgrades are required:
For Max Power (600whp): You must run the Dorch Engineering Stage 2 Fuel Pump.
For B58TU / Dorch Stage 1 Pumps: You can still run this turbo, but power figures will be lower due to fueling limits (as seen in our test logs).
