How do you benefit from a Thomson Supercharger? As most owners know Harleys are not high RPM motorcycles. With a modern Harley Davidson red lining around 6000 RPM, there isn’t much to be gain from supercharger that produces max boost at 5500 to 6500 RPM. The Thomson Supercharger uses a patented fixed displacement roots design, which delivers large gains in the low and mid range RPM. Our design is very well suited for the low revving v-twin engine, because of its rapid boost rise. This means USABLE , ON DEMAND power for your Harley.
Although many roots supercharger manufactures have gone to multi lobe rotor design, Thomson Supercharger uses a twin lobe rotor design. Working closely with Don Hampton of Hampton Blowers ( The true king of supercharging), We have fit our case with the new Hampton Super II helical rotors. Don Hampton has spent 25 years developing his record-breaking rotor design, and has allowed us at Thomson superchargers to bring that technology to your motorcycle in a more compact form.
We have spent years planning and performing R&D to specifically size and optimize our supercharger for your application. By utilizing the Hampton Super II design we have been able to increase not only thermal, and volumetric efficiencies, but the internal volume of the blower case as well. This allows us to supply you a much larger C.I blower in a much smaller package.
Our patented belt drive system allows us to tailor boost levels, and curves to your specific riding needs. It also provides you as the consumer with multiple levels of performance. Pulley ratios can be changed in a matter of minutes. The drive system also acts as a security for your engine. If for any reason there is a major component failure in the supercharger, the drive belt will simply slip or break, leaving your engine free of damage. Be assured the engine will still run with the belt detached, it will simply run with no boost.
The Thomson Supercharger was created as an alternative to traditional power parts/ modifications, although it will work along side with these mods. Stroker kits, big bore kits, cams, heads, porting/polishing, carburetor …..ETC. These are all great products and have there place in the motorcycle industry. The problem is, they produce power at great expense, and lots of down time. They also allow little to no adjust ability of power without more major parts changes, and expense, and almost all can not be reversed. Meaning if you sell your bike you will lose your investment.
