B&M Holeshot 3000 2800-3200 RPM Hi Stall Torque Converter B&M offers a wide range of performance torque converters to fit almost everybody’s needs. All B&M converters are precision engineered, spin balanced and pressure tested. Performance converters are furnace brazed for strength.Suitable for VT VX VY VZ Holden Commodore & HSV LS1 5.7lt Gen3 V8 4 Speed Auto 4L60E The B&M environmental drive train development lab is a key tool used in the development of every converter designed by the engineering staff. Precision engineered, tested and the success at the track provide prove that B&M torque converters are the finest you can buy. A higher than stock stall speed as delivered by the Holeshot converter will provide several advantages and benefits in vehicles with modified engines. Many modifications, particularly big cams, tend to reduce low end power and torque. The high stall converter allows the engine to launch the car at a higher rpm where more torque is available. The Holeshot is generally a very good choice for the typical street machine that is looking for better launch capability and more strength. Street rods with modified engines will also benefit from a Holeshot converter. Furnace brazed impeller, precision steel alloy pump drive tube, heavy duty needle bearing between stator and impeller (not a thrust washer), needle bearing between stator and turbine & a furnace brazed turbine all combine to make this converter stand up to the punishment of a high performance application. Unlike many other options on the market, these converters retain the Electronic Torque Converter Lock for relaxed highway cruising. Specifications:
Why do I need a B&M torque converter? The reason for considering a B&M torque converter boils down to performance. Higher stall speed is the key. A higher stall converter allows the vehicle to accelerate better from a dead stop and may provide tyre smoking performance. What should I expect from a performance torque converter? Strength and durability is an additional benefit if the converter is properly engineered. Furnace brazing is used to strengthen the converter internally for high performance, racing and heavy duty applications. What is stall speed? Stall speed numbers are listed primarily to rate the converter’s performance level. Typically, the number assigned, 2000, 2400, 3000 etc, lets you know what to expect from the converter. If a 2400 is selected, you should be able to footbrake stall the converter to about 2400 RPM. This should provide anywhere from 500 to 1000 more RPM to launch, or accelerate, the vehicle from a dead stop, as compared to the stock converter in the vehicle. This increase should substantially improve the acceleration capability of the vehicle. Lighter cars, 2800 lbs and under, typically stalls a little lower than the above mentioned numbers, therefore you should choose a converter with a higher stall number for optimum performance. How does the engine’s camshaft affect the torque converter’s performance? The camshaft will affect the torque curve of the engine, which will affect the performance of the converter. For example if your 350 cid engine produces 230 lb.ft. of torque at 2400 rpm a B&M HoleShot 2000 converter will produce 2000 rpm stall speed. If you install a 268-degree cam into this engine you will raise the torque curve and at 2400 rpm your engine will produce less torque. Thus the 2000 stall converter will only stall at 1800 or less. However with this new cam the engine will make much more power above 3000 rpm. Keep in mind when the torque curve of the engine is raised you will need more stall speed in the converter to allow the vehicle to accelerate at low rpm (below 3000). A good rule of thumb for advertised cam durations up to 248 degrees, a 2000 or 2400 stall converter is a good choice. Advertised cam durations up to 268 degrees, a 2400 or 3000 stall converter is a good choice. Advertised cam durations over 272 degrees, a 3000 to 3600 stall converter is a must. Fitment notes:

Volkswagen designer gets 2011 lifetime achievement award
Tue, 21 Jun 2011Volkswagen Group designer Walter de'Silva was chosen for this year's Lifetime Design Achievement Award at EyesOn Design, which ran over Father's Day weekend in the Detroit area. About 260 invitation-only vehicles were in attendance at Sunday's car show on the grounds of the Edsel & Eleanor Ford House in Grosse Pointe Shores. They were chosen based on this year's theme of "Designing for the Future." Only car designers who have previously won the Lifetime Design Achievement Award were allowed to vote on a winner for 2011.
Mercedes SLS AMG E-Cell – First prototype
Tue, 22 Jun 2010The subtly painted Mercedes SLS AMG E-Cell Prototype We called it the Mercedes SLS AMG eDrive when we first talked about an electric SLS Gullwing last year. Although to be fair that’s what Mercedes called it when they gave us some info and confirmed they were working on creating an electric version of the SLS. But it now appears to have become the Mercedes SLS AMG E-Cell Prototype.
