Warre2

Anyone who has driven a Hummer H3 has commented on the lack of power. Even with a manual transmission, the acceleration leaves a lot to be desired. In an effort to resolve this concern, European automotive technology company, Antonov, will be showing its innovative 2-speed supercharger drive system at the Specialty Equipment Market Association (SEMA) show next week in Las Vegas. After mounting the unit on the power steering pump bracket of the I5, the supercharger is overdriven at 1.36 to 1 from off-idle to about 4200 rpm under hard acceleration, then mechanically steps down to a 1 to 1 ratio at higher RPM's. The higher speed of the supercharger impellor increases power and torque to the rear wheels by an impressive 58 percent at lower engine speeds changing the personality of the H3 dramatically. Antonov is also researching other applications for its multi-speed mechanical drive systems. The smaller displacement hybrid engines could use some forced incduction as an economical means for more low end power. The Autoliv system can be designed as a 2, 3 or 4 speed unit allowing the supercharger to be tuned to the specific needs and calibrations of the powertrain application. This really sounds like a cool technonlogy, and one the H3 certainly screams for. Hot rodders have been switching to smaller supercharger pulleys to achieve this affect for years, but at higher RPMs there was always a chance of overspeeding the supercharger and causing heat-related issues with the rotor seals. Wouldn't it be great to set the boost level of your engine based on RPM; even better, if it were switchable from inside the car? In a Mustang GT application, Autonov was able to "hide" the compact supercharger/drive unit under the intake manifold. Reminds me of the NOS bottle hidden inside the heater core box with jets plumbed under the intake manifold of my '68 Camaro. Could this the newest trend in "secret" perfomance mods? Antonov Unveils First Two Speed Supercharger Text & Photos courtesy Antonov plc Worlds first enters series production The world’s first two speed supercharger drive system to enter series production will be demonstrated by Antonov, the automotive technology company, at the Engine Expo exhibition at Stuttgart in Germany next week. The following week, the racing driver Peter Kox will demonstrate the technology at the Zandvoort race circuit in the Netherlands. And see the results: http://www.antonov-clubsite.nl/000000962f0...0001/index.html http://www.antonov-clubsite.nl/000000962f0...fa03/index.html Antonov has given on the 16th and 17th may 2006 a demonstration with a Ford Mustang and a Chevrolet 1.8 ltr. Both cars where build with a combined Rotrex/Antonov AMM 2-speed step up supercharger. On the URL above all movies who are made at race circuit Zandvoort (The Netherlands) concerning the driving performance off both cars.

In 31 oktober 2006 it will be demomstrated at the SEMA show in Las Vegas. Very good movie!!!! http://www.nmratv.com/index.php?stream=htt...&playlist=1 There is also a http://www.AntonovForum.com Here we have all kind of discussions about this Antonov technology. http://members.lycos.nl/magpie69/Antonovpatents.htm (About all the Antanov patents and historie of the Antonov company and much more information).
