Berk Technology Wins Inaugural MotoIQ PTCC Race!

March 8, 2011

Fresh off of winning the 2010 Redline Time Attack Street Tire RWD Championship, the Berk Technology team and their BMW 135i headed out to Willow Springs Raceway to compete in the first ever Pacific Tuner Car Championship (PTCC) race.  The new series is the brainchild of Mike Kojima and pits time attack style cars against seasoned road racers in a half hour long wheel-to-wheel sprint race where the first to cross the finish line wins!  The Berk Technology BMW 135i was placed in the Tuner Over class which features the highest horsepower and quickest cars of the MotoIQ series.

The Berk Technology BMW 135i has already proven itself as a consistent winner in 2010 yet the team continued to refine the chassis in the offseason.  Additional enhancements were made to the cooling system and AEM Methanol kit for further reliability over the course of the 30-minute race.  The new PTCC series allows for any DOT legal tire so the Berk team opted for the Hankook Z214 DOT racing slick wrapped around a new set of VMR Wheels.

Mike Bonanni once again served driving duties behind the wheel of the mighty 135i.  Bonanni set the pace early on by qualifying the car on the pole position against a star studded field with the likes of FormulaD all-stars, Daijiro Yoshihara and Joon Maeng, and GrandAm driver, Brian Lock.  As the green flag dropped Bonanni was first into turn one with the Berk Technology 135i with Brian Lock his Nissan 350Z close in tow.  Bonanni extended his lead over Lock to over four seconds before the race would receive its first and only caution flag.  After the single file re-start the Berk 135i kept the lead into turn one and remained there until receiving the checkered flag as the first ever PTCC Champion!

“This was a really fun and challenging change of pace for the Berk Technology team.  We proved last year that we could make a car that was capable of turning a fast lap.  With this race we proved that we could also turn consistent fast laps over the course of a 30 minute wheel-to-wheel race.  It feels great to qualify first and win our first event in the new MotoIQ PTCC series.”Mike Bonanni, Driver of Berk Technology BMW 135i

Berk Technology would like to thank Hankook Tire, Performance Friction, KW Suspension, European Auto Source, VMR Wheels, GIAC, VFiber, APR Performance, SEIBON Carbon, AEM Electronics, and OS Giken for their support.  We would also like to thank and Redline Track Events for putting on an excellent event.  You can see the Berk Technology BMW 135i next at the fifth annual MFest event in Las Vegas, NV April 22nd – 24th.

Berk Technology to Compete in Inaugural PTCC Race!

March 3, 2011

The 2010 Redline Time Attack Street Tire RWD Championship winning Berk Technology BMW 135i is getting back on the tarmac this weekend at the inaugural Pacific Tuning Car Championship race!  The race will be held at Willow Springs Raceway on March 5th & 6th in conjunction with the 2011 Redline Pro Time Attack, Pro Track Challenge, and Circuit Battles season opener!  The PTCC series pits time attack style cars head to head in a 30 minute wheel to wheel race where the only thing that matters is crossing the finish line first!  There are two classes in the series, Tuner Under and Tuner Over which are mainly separated by power to weight ratio.  The Berk Technology BMW 135i will be competing in the Tuner Over class which features an 8:1 power/weight ratio, the faster of the two classes.  We will see the return of 2010 driver Mike Bonanni behind the wheel of the 135i again as well.

“I am extremely excited to be able to get back behind the wheel of the Berk Technology 135i and perhaps just as excited to embark on the new challenge of putting this car thorough the paces of wheel to wheel competition rather than traditional time attack.” – Mike Bonanni

Berk Technology kicks off the season with virtually the same car we ended with last year.  Hankook Tire is back on board but instead of the incredible Hankook RS-3 street tire that took us to the Championship in 2010 we are now able to run on the equally incredible Hankook Z214 DOT racing tire!  Performance Friction is also on board and we will be putting their innovative new BMW 135i Z-Rated big brake kit through its paces.  KW Suspension, OS Giken, APR Performance, SEIBON Carbon, GIAC, AEM Electronics, Macht Schnell, VFiber, and European Auto Source are among the other returning sponsors from 2010.

More information on the Pacific Tuner Car Championships as well as the other events happening this weekend can be found at  See you at the track!

New Honda S2000 3″ Header Back Exhaust!

January 4, 2011

Berk Technology is proud to announce the official release of our new 3″ header-back exhaust system for the Honda S2000!

We’ve been developing this exhaust for some time now and I think it’s about time to spill the beans. There are a TON of exhausts on the market today but this one has many design features that has not been seen in one complete package. We’re proud to introduce the Berk Technology 3″ Single exit exhaust for the performance minded enthusiast. Don’t be scared by the size baby, let me explain…..

You still hear people talk about the need for backpressure in exhaust threads and to this day many people spread wrong information on the subject. The internet myth that “some back pressure is good” still persists. Let me just kill it now, back pressure is never good and any motor will perform best with zero back pressure. The myth confuses back pressure with velocity (exhaust gas speed) and in our case we are lucky that Honda makes one of the best flowing cylinder heads in the world, bar none. When you mate an exhaust system up with lots of flow capacity without any kinks, flanges, or resonators to deal with you end up with the best of both worlds. The lowest backpressure possible while maintaining exhaust gas velocity for low to midrange RPM performance. This all translates to power production from down low all they way up to redline.

Enter the Berk Technology 3″ Single for the S2000. We designed this to be as light as possible, with a slightly understated look, and most importantly to make POWER everywhere. We utilized a header back design to minimize the extra weight and complexity from extra flanged connections. The efficient layout also allowed us to make the exhaust as straight as possible to keep velocity up for better all around performance in any RPM range. We use a V-band connection and a single bomb proof Clampco clamp that has never failed us in our 6 years of turbo system development and manufacturing. The design of this system keeps weight to a minimum, shaving off almost 1/2 of the weight of the stock system.

Our muffler is a true straight through 3″ muffler with a proper perforated core that does will not slow down the flow of exhaust gas while still offering an excellent amount of sound attenuation without too much harness. This definitely isn’t what I would call a quiet exhaust but it is quieter than some of the already available 70mm exhausts on the market.

Need to stay SMOG legal? We have full custom fabrication in-house and can add a high flow cat to your exhaust. It doesn’t have to be as fancy as the quick release V-band HFC/TP option I have shown at the bottom of the post but it gives you an idea of what you can do.

•3″ Single exit exhaust (76.2mm)
•4″ Straight cut tip
•Header back, meaning the “test pipe” or “High Flow Cat/HFC” is an integral part of the exhaust
•Built in CEL fix is included with the non-catted or high flow catted option
•Single V-Band connection that uses zero gaskets and is quick release with only one nut to remove.
•Extra support hanger is included. Prevents “wobbling” of the exhaust.
•OPTIONAL: High flow cat option with or without quick release V-band connections.
