The debate between NA and forced induction is something that will never die. It鈥檚 fair to say if you want power you go forced, if you want response you go NA. If you want big power with response you get some stupid displacement V8 or V10 but then again, they don鈥檛 have an econo-mode like a turbo car does out of boost. Now, smaller bore turbos, twins or sequentials can be a bit of sweet spot where you get all the pull without the lag. But what if you try what the Japanese have been doing for many years? Going with the instant response of a supercharger and couple that with the overlap of a turbo to provide the rest of the boost? Now that鈥檚 progress.
Admittedly I wasn鈥檛 super familiar with this technology because North Americans weren鈥檛 big on forced induction in production cars. But in the 80鈥檚 the turbo technology hit the market like a roundhouse kick. And spawned all kinds of marketing catch phases and products that integrated the word 鈥楾urbo鈥 in them some capacity. But it wasn鈥檛 until I went overseas that I realized there were hybrids using both turbos and superchargers and tiny 660cc engines to optimizes their inherent lack of torque and horsepower.
Dennis Wang of Fountain Valley, CA realized that his NA 3-series sedan needed more kick. Sure the 3.0L inline-6 lurking under the hood of the 330i is capable but a total boat anchor compared to what it has become. When it comes to building something that gets noticed in Los Angeles, Wang made a smart move and turned to Ben Abutin of High End Performance. High End is of course, killing it at the shows and in all of the magazines, showing no signs of slowing down with their bold moves in the sport compact world.
Abutin鈥檚 crew fabbed-up a custom manifold to house the Garrett GT-30 ball bearing turbo now forcing the chamber with air. But further upstream is a custom centrifugal supercharger, high-polished and tuned to light the 6-shooter up immediately. A K&N conical filter draws in air into a maze of 2.5-inch polished intercooler piping eventually landing in the custom intake plenum. Dumping the spent gases is a TurboSmart 48mm wastegate while unneeded air is vented through twin TurboSmart blow-off valves. Post combustion, exhaust heads into a 2.5-inch downpipe and bumps up to a 3.5-inch midpipe and flows out twin exits. What the forced induction can鈥檛 accomplish, the NOS fogger system will feeding the motor from twin 10-pound bottles. The whole setup was tuned by Split Second resulting in a combination pushing 400whp out of a stock motor running 7psi.
Under the chassis are all the right moves considering the Ultimate Driving Machine already has lots of right moves from the factory. The dampers were replaced with a set of KW鈥檚 Variant 3 coilovers for high adjustability. The factory sway bars set to understeer were beefed up with some Eibach units for desired stiffness and tail-out driving. The stoppers are some Ferrari-caliber gear from Brembo ready for any conditions. In the rear are 4-pistons with 345mm cross-drilled 2-piece rotors but upfront are 6-pistons with massive 380mm brutes.
To accommodate the brakes, Wang needed some serious rollers. Wheels that would not only clear these brakes but fill out the wheel wheels for the flushness that is basically mandatory in a project of this magnitude. Wang chose the C20 from HRE, a charcoal wheel with a polished lip. The wheels are 19x9, and those are just the fronts! The rear rollers are 19x11-inches cloaked in Falken 452s measuring 315/25R19!
The widebody look of the car did not come easily. It is a combination of rare parts, custom parts and more labor than most enthusiasts could stomach paying for. The car is fitted with a full AC Schnitzer bodykit, modified to accept the custom widebody. The rear wing is custom as are the carbon fiber mirrors and kidney grilles. The carbon doesn鈥檛 stop there with AC Autotechnic carbon fiber B-pillars, Fusion door sills and a Vorsteiner double-sided hood. Lighting got a boost with genuine Euro E90 tails and headlights fitted with Fusion HIDs and angel eyes. The project was resprayed in Artic White and given a custom triple stripe a la BMW Motorsports.
Inside the fiery 4-seater, is well, a cage that makes it only a 2-seater. A Chromoly 14-point cage weaves around the cabin protecting the occupants and making the car solid like a chunk of billet. The Recaro SPG buckets are drapped with Schroth 5-point harnesses (well 4-points for men). Fusion provided many of the interior carbon fiber accents including: steering wheel, wheel trim, e-brake, shift knob and various inserts. The balance of the interior got a custom suede treatment wrapping the: armrest, wheel, airbag flaps, door panels and headliner. The cage also doubles as a great mount for many accessories, the obvious being the harnesse but a camera, bottles and even the Defi gauges. Above the driver is a unique setup of the Defi gauges including: boost, EGT, oil pressure, water and oil temperature. Boost is regulated with a TurboSmart e-Boost2 and the AFRs are displayed with an Innovate wideband gauge.
Since this E90 hits the show circuit in addition to being one hell of a SoCal cruiser, a load of audio and advanced multimedia was injected into the project. Probably the most striking upgrade was all of the Apple gear onboard. A fully functional Mini Mac is installed along with a 20-inch Apple cinema display as well as a wireless keyboard and mouse. The audio comes courtesy of Helix, where a full deployment of speakers, subs and amps is found throughout. Up front are 6-inch two ways with 5.5-inch 2-ways in the rear doors and another pair in the trunk. Power in the quartet of Helix 10-inch subs is a pair of 1300W Helix A1 amps. A single 6-channel 640W Helix A6 and A2 1300W runs the balance of the components. The flush mount DVD player is connected to the I-drive as is the rear backup camera for ease of toggling between sources, that also includes a Nintendo Wii.
Lots of labor and plenty of innovation is paying off as this Bimmer is cleaning up at shows. The crowds at Bimmerfest 鈥08 couldn鈥檛 even wrap their heads around what they were looking at. The judges however did and gave Wong鈥檚 creation top honors with Best of Show. And a High End Performance car yet again makes it into the mag, no bribes required.
