Ready to take your BMW twin turbo to the next level? How does an additional 80hp and 80tq to the wheels on an otherwise stock car on pump gas sound? How about up to 180hp and 155tq to the wheels on a fully modified car on race gas? Then Burger Motorsports’ new Juice Box 3 is just the product you’ve been waiting for. Bettering upon previous models, Stage 3 improvements include crank position for full 4D engine mapping, air intake temperature for on the fly thermal loading adjustments, direct solenoid control for precise spike free boost control, throttle input for factory like drivability, and fuel pressure control for diagnostic invisibility. In addition, new internal safeguards such as over-boost protection, boost spike protection, and maximum allowable boost solenoid offsets have been incorporated making the JB3 one of the safest tunes available.
Burger has also made installation a snap! Because the JB3 was designed from the ground up specifically for the N54 platform, Burger was able to optimize the unit for reliability and ease of install. The JB3 does not require complicated external power or ground taps which can leave tell tale signs of modification or trigger detection codes, making it the only true plug and play N54 system available. The JB3 box and harness are designed to fit discretely in the ECU compartment with no visible signs of modification. JB3 is offered with two wiring harnesses. Plug and play (PnP), and professional (pin-out). The PNP includes color matched sub-connectors and does not require counting/extracting ECU pins. Installation takes only 15-20 minutes. The pin-out (suggested for more experienced enthusiasts) uses OEM BMW pins in similar manner to JB1 and JB2, and has an install time of 30-45 minutes. Neither version requires the solenoid bypass or any vacuum line changes making removal a snap!

We have installed the Juice Box 3 on Bottle’s 335i, and he loves it. Installation was straight forward as indicated by Burger, and the performance was right on the money. Look for possible track footage in future posts.
Spearco Intercoolers introduces a new large capacity, high flow, front mount intercooler upgrade for the BMW 335i coupe and sedan, increasing horsepower and torque. Made for those looking to increase the horsepower and efficiency of their 335i to match the great factory torque delivery, Turbonetics heat exchanger brand Spearco, now offers bolt-on upgrades for the 2007-up 335i coupes and sedans.
• 14.38 horsepower average increase over stock at higher boost levels
• Averaged 14.3 pressure in and 14.1 pressure out – Only 0.2 pressure drop
• Temperature drops average over 125° F and 10% better than stock
Details:
• Bolt-on intercooler kit…no modifications required.
• Bar and plate core design – designed for rugged conditions and high boost levels.
• Computer modeled core design – high effectiveness and low pressure drop.
• Works with all ECU upgrade programs.
• Strong aluminum end tanks and piping replaces the weak factory plastic
• Installs in under three hours
• Part Number 15179
BMW owners can now enjoy the benefits of increased flow and more efficient air to help dramatically lower intake air temperatures to increase power. By using a massive 6″ thick W.A.V.E. Technology core, the Spearco front mount intercooler dropped charge air temperatures on average of 125 degrees on the twin turbo vehicle. In addition to lower intake air temperatures, the pressure of air exiting the intercooler compared to the pressure entering the unit was only an amazing 0.20 psi drop. The stock unit has over one pound of pressure loss/drop due to the factory unit’s lack of efficiency and limited size. When the stock unit is upgraded to the Spearco you will have less heat and more power due to the ability to quickly and efficiently move the pressurized air through the intercooler assembly.
Once the initial investment is made, the result is a lifetime of free power and improved fuel economy. The intercooler reduces charge air temperature entering the engine, increasing the air density for increased power and torque, while reducing the overall thermal load on the engine and cooling system as exhaust temperatures are reduced at the same time. This results in less transfer of heat to the cooling system, and engine compartment and assists in maintaining normal temperatures on long hard power pulls. Since the intercooler is mounted in the factory location there is no need to worry about making any modifications to the vehicle. In addition to power and performance, you can anticipate an increase in fuel economy as the cooler, denser air creates a leaner air-to-fuel ratio.
Spearco’s drop-in replacement intercooler upgrade features W.A.V.E. Technology bar and plate cores for increased strength and efficiency by utilizing the maximum surface area of the cores available each core is pressure tested to over 200+ psi. Hand crafted and precision welded, each Spearco assembly is fabricated to strict tolerances and every unit is pressure tested underwater to ensure a leak free intercooler assembly. The Spearco Intercooler upgrade drops in place very easily in 2-3 hours time. Combined with higher boost pressures, the Spearco 335i front mount intercooler provides a win-win combination of additional power and increased efficiency.
Turbonetics introduces compressor anti-surge and turbocharger protection for the BMW 335i coupe and sedan. Designed to minimize wear on the internal bearings of the turbochargers and provide increased throttle response, the 335i BOV kit combines increased durability and performance.
BMW owners have always understood the link between form and function. Just like the factories the vehicles come from aftermarket parts need to live up to design and performance. The Turbonetics 335i BOV kit surpasses both standards. As today’s cars become more and more finely tuned to wring every last bit of performance and fuel economy, certain parts are called on more than others. The forced induction system on the 335i’s N54 engine platform is pushed to greater limits with small twin turbochargers come from the factory running higher than average boost levels. With higher boost comes added stress on the turbochargers rotating components. A well designed and efficient blow-off valve kit helps to alleviate unnecessary wear and strain on the turbochargers internal thrust bearings, turbine wheel shaft, increase lifespan and improve performance.
Kit features:
• Twin Raptor Blow-Off Valves easily handling 600+HP for maximum flow and efficiency
• High flow BOV filters to prevent particulate entry and noise suppression
• Polished aluminum BOV’s for high strength & clean looks
• Filters are removable for increased sound appeal
• Polished aluminum horns available separately
• Precision machined adaptor flanges to mount to factory positions
• All hardware, and accessories necessary for installation
Why are blow-off valves important? The turbocharger is moving large amounts of air while under boost, and this pressure is being delivered to the engine while the throttle is depressed. As soon as the throttle is lifted the butterfly closes in the throttle body preventing the pressurized air from entering the intake manifold. Because the engine is still moving exhaust gases and the inertia of the turbocharger is turning the turbine and compressor wheels, the air literally stacks up against the throttle blades. Pressure builds up within the system’s piping extremely quickly and once it reaches the compressor wheel the air actually flows back out of the compressor inlet and limits the compressor from rotating. Because of the air reversing direction the pressure drops allowing the wheel to spin and once again raise the pressure. This process of up and down pressure and air reversal is surge and the result is the fluttering/barking sound that comes from the turbo. Surge is very detrimental to the turbocharger, resulting in various stresses being placed on the unit. The compressor wheel has high loads placed on it as it tries to move against this wall of air, and as high pressure air finds its way behind the compressor wheel. Compressor surge can result in the compressor wheel spinning on the shaft, shaft breakage, bearings to have unnecessary wear and potentially create contact between the wheels and housings.
The compressor blow-off valve is placed after the intercooler and before the throttle body to help eliminate the pressurized air. Vacuum controlled, the BOV receives a signal from inside the intake manifold or just after the throttle body, pulling up on a diaphragm, causing a valve to open inside the unit. The pressurized air that is discharged is then routed back to the inlet of the turbocharger or vented to atmosphere protecting the compressor from surge and assisting in maintaining the speed at which the turbochargers wheels are turning improving throttle response and drivability.
