Turbosmart’s Performance Guide: Porsche 911 Turbo (996)

The Porsche 911 Turbo is one of the great legends of the supercar world. Few other pedigree sports cars offered the same blend of everyday useability and extraordinary speed.

The first of the watercooled 911s, the 996 has become the bargain of the 911 family on the used car market, and the Turbo model has depreciated to a point where it offers a serious performance car for reasonable money.

If you have been lucky enough to land yourself one of these legendary turbocharged sportscars, Turbosmart has a range of simple bolt-on performance upgrades that can help take your 911 Turbo experience to the next level.

Even Stuttgart’s best is built with compromises in boost control. Turbosmart’s precision-engineered bypass valves, blow-off valves and internal wastegate actuators offer improved turbo response and reliable performance for both stock and tuned 911 Turbos.

Turbosmart Upgraded Bypass/Blow-Off Valves

Even in unmodified vehicles, the 911s standard turbo bypass valve and wastegate actuator leave room for improvement. The 911’s bypass valves are responsible for preventing the turbo from experiencing compressor surge, by relieving pressure within the intercooler piping that builds up when the throttle is suddenly closed. However, the standard bypass valves are constructed of plastic, struggle to hold boost and degrade over time, causing boost leaks. In tuned vehicles running increased boost levels, the problems with the standard valves become even more apparent.

Turbosmart offers direct replacement billet-constructed Kompact bypass/blow-off valves. These are available in both OEM-style Plumb Back style, in which the vented air is recirculated back into the vehicle’s intake, and a high performance Dual Port variant, which provides a head-turning vent-to-atmosphere blow-off valve sound. Turbosmart’s Kompact valves are capable of holding extreme boost levels, and keep the Porsche’s turbochargers safe from compressor surge.

Turbosmart Upgraded Internal Wastegate Actuators

Turbosmart’s upgraded Internal Wastegate Actuators for the Porsche 996 Turbo provide better turbo response and greater sensitivity when managing boost pressures. The standard wastegate actuators can be forced by exhaust back pressure at high RPMs, causing boost to drop off and the car to feel flat at the top end.

Turbosmart’s IWG-75 Internal Wastegate Actuators are developed with the ultimate in performance in mind, improving boost response for the factory turbochargers. They have larger diaphragms and stiffer springs than the standard units, meaning it is harder for them to be forced open by exhaust pressure, giving you better performance throughout the rev range. They are also designed with the highest quality materials for ultimate durability and heat resistance.

The IWG-75 is available in two different base pressures. The 7PSI variant is ideal for stock vehicles, while the 24PSI variant is great for tuned vehicles running increased boost pressures, where the standard actuator is overcome by exhaust pressure before peak boost is reached. The IWG-75’s locking collar design makes spring changes quick and simple, should a different base pressure be required.

All of Turbosmart’s products for the Porsche 996 911 Turbo are direct replacements for the factory parts, and require no special tools or fabrication for installation. It really couldn’t be easier to unlock the extra power from your 911 Turbo.

Team Turbosmart’s Odi Bakchis wins Formula Drift Round 6

Team Turbosmart’s Aurimas ‘Odi’ Bakchis has won the sixth round of the Formula Drift championship, held at Evergreen Speedway in Monroe, WA on August 5-6.

After qualifying in second place, Odi’s impeccable technique and style throughout the event saw him edge out his competitors in each round. Driving his Turbosmart-equipped supercharged LS7-engined Hyundai Genesis Coupe, Odi came out victorious against Forrest Wang, Frederic Aasbo, and Ken Gushi to make his way into the final.

For the final battle, Odi went head-to-head with championship points leader Chris Forsberg. Bakchis led the final battle with a precise lead run where Forsberg made contact with Bakchis and spun in the infield. Once in the chase position Bakchis exhibited extraordinary car control as he stayed close to Forsberg, yet still avoiding contact when Forsberg again over-rotated on track. Bakchis was unanimously awarded the event win by the judges.

“I’m really happy with the win,” Odi told Formula Drift following the event. “I really want to keep this momentum going into the next round and am excited for the rest of the season.”

Odi currently sits in fourth place in the overall championship. Round 7 heads to Fort Worth, Texas on September 9-10.
