GSR Autosport BMW 350R: Partial III – Contrast, tuning as well as subordinate
Formula DRIFT is famous as the North American veteran drifting championship series. Autoblog has been invited behind-the-scenes with GSR Autosport, and their motorist Michael Essa, as the team builds, tests and campaigns a V10-powered BMW 350R during a 2010 racing season. This is the third installment in our array (see Part I and Partial II) as we follow the team throughout the creation, testing and competition deteriorate.
The BMW V10 ripped from an M5 as well as transplanted into the 3 Array does turn over upon the first try – but afterwards it starts to explode. The GSR Autosport group shuts it down promptly and dials Peak Speed Technology. A engine and its related wiring are the most worldly part of the 350R. Its digital ECU is tasked with determining fuel, spark, four-cam VANOS, twin drive-by-wire, electronic oil pumps as well as the variable-speed electric cooling air blower. Without delay, the experts diagnose a complaint (exhaust cams) as well as download the few fixes to a S85B50’s ECU. Set straight, the BMW Motorsport engine growls but a hiccup.
Once the engine is warmed, Michael Essa does just what many of us would do – he takes the brand-new 350R for a celebratory turn around the retard at a industrial complex as well as does screaming donuts in a center of a dull travel.

The car, still missing its front fender, metalcover, rooftiles and windows, isn’t exactly done… but it needs to put some time in at a lane to be honed. A group loads the 350R into a sealed trailer as well as heads for Willow Springs General Motorsports Playground in Rosamond, California.
Willow Springs Speedway, a quarter-mile paved oval, is the smallest track at a desert complex (not counting kart tracks). It’s a lousy road co urse, though the open figure-eight is a perfect drift for testing a drifter. Unloaded from the supply, entirely fueled as well as running an engine map borrowed from the performance-tuned travel M5, Michael takes a few prohibited laps to get the feel for a car. Afterwards he takes many, most more.
Over the next multiform hours, shock settings have been tweaked, springs have been practiced as well as tire pressures have been both bled and increased. A last settings are as rhythmical as a recipe for Coca-Cola.
Power does not seem to be an emanate, though weight is (lack of poundage, for improved clarification). The 350R is light in a back Recollect, all was stripped out of the back of the car while 50 additional pounds of V10 were added to the front), so the mutated BMW is run with a full tank of fuel for some-more rearward weight disposition. Calm with the direction of the contrast and tuning, everything is loaded back onto the trailer for a float behind to the emporium.
A next visit is to the dynamometer. Strapped down resolutely, the V10 puts up an angry quarrel and sends about 450 horsepower to a rear wheels. (Thanks to driveline loss as well as the rear differential utilizing a 10-inch ring gear which isn’t exactly energy fit, the best theory says it is cre ation an estimated 550-570 horses at a crank.) A group tweaks a ECU and finds alittle more energy.
Dual days after, a GSR Autosport 350R is removing embellished. A extraneous is sprayed glo ssy black, while the interior is shot bright china (the lighter interior helps a in-car cameras with automatic white balance – no joke). The wheels receive a two-stage powder coat. The y have been coated in splendid white followed by a garishly bright orange – Michael Essa’s signature color. You can’t skip them.
Whilst stock bodywork is retained for rightaway, the custom carbon-fiber widebody pack is being constructed – it will shave another 100 pounds off a curb weight. Lexan windows reinstate a rear units, though the side entertain panels remain glass (the Lexan side windows usually save dual pounds each). Capping the drifter is the lightweight co fiber rooftiles systematic true off a E92 M3 tools sheet.
As you read this, the GSR Autosport 350R is sitting on the grid qualifying for the Regulation Drift Round 1: Streets of Long Beach during the Toyota Grand Prix travel march. Months of tough work, tens of thousands of dollars, countless individual contributions, and a generous assistance of sponsors have done the softly deranged thought of flapping the V10-powered BMW 3 Series the highly-competitive reality.
We’ll tell you how the group did next week.
