omfg check out this new roush supercharger:
ROUSH Performance: TVS2300 ROUSHcharger® Kit (Complete Kit) Detail

Kenne bell/whipple or nothing.

dude this aint no kenne bell or whipple but this is finally a decent roush charger... the others aren't so nice... 700HP from this charger

haha, I have to agree with you there, unless of course you need a centrifugal charger for a mach 1 or something. Still nice though.

why are kenne bell and whipple so much better than roush?

The twin screw design allows for a sh*tload of horsepower... I guess they're just legendary names. That roush charger does look neat, but for that price you have a kb or a whipple.

Hello, We use to mess with the twin screw charger on the 3800 series I and II. This charger act like a turbo but funtion like a roots blower. Its the ideal blower for drag racing. this charger is able to make massive power, because of it ability to compress air inside the blower. The boost comes in very quick at low rpm. This massive power increase can also cause damage to the driveline, if not build to with stand. I am sure ford did a excellent job on the s/c mustang.

Ford chose the Lysholm supercharger for the new GT. Mercury Racing (marine) also picked the same SC for their 1075 HP engine. Ford Racing has also chosen Whipple to be it's sole aftermarket SC provider.
Just because Ford never selected the Autorotor surely does not mean it is inferior to the Lysholm. There were price considerations and politics involved, not “passing tests”.

Companies currently manufacturing twin-screw superchargers include Kenne Bell, Lysholm, Autorotor, Whipple, PSI, Ingersoll-Rand, Kobelco, and Sprintex.

I would like to think roush must have bought out the Kenne Bell also Jim Bell(GREAT GUY) business.

The Lysholm designed compressor was designed by the lead designer of the Autorotor, he left Autorotor and help start Lysholm and develop a new compressor that had new design features. The Lysholm rotor, bearing, shaft and gear design was not only backed by Eaton (the most successful supercharger mfg. ever), but also passed all of Eaton and Fords durability and endurance test. Something the Autorotor has never successfully done. Ford chose the Lysholm supercharger for the new GT. Mercury Racing (marine) also picked the same SC for their 1075 HP engine. Ford Racing has also chosen Whipple to be it's sole aftermarket SC provider.

Whipple had the rights to the Autorotor supercharger, Whipple brought the compressor to America and supplied Kenne Bell superchargers. There was a gentlemen’s agreement that Whipple would target GM vehicles while he targeted the Ford market. Whipple released the rights to go with what Whipple felt was a better future solution and Whipple ended our business relationship with Jim Bell. Whipple knows the entire history of Autorotor, they were the largest distributor for years.

Jim Bell is a very intelligent person and has made some incredible products, he's a very likable character, but we need to keep the facts straight.

Bell mentioned that Opcon Autorotor purchased Lysholm but in fact, the owners of Lysholm took controlling shares of Opcon for the purchase. This was very clear in the press release.

Kenne Bell Web Home

A man by the name of Heinrich Krigar in Germany on March 24th, 1878, patent #4121, first patented the principle of the screw compressor. He modified and improved his designs later that year and lodged a second patent (number 7116) on August 16th, 1878. Both of these patents are amongst the earliest on record, as the German Patent Office had only been formed just one year earlier.

Heinrich Krigar resided in Hannover and his illustrations clearly show a two-lobe rotor assembly, each rotor having the same profile as each other. In fact the rotor configuration resembles the Roots design, exhibited in Europe during 1867, with the exception that the rotors in the Krigar screw compressor twist through an angle of 180 deg along their length.

At that time it was not possible to develop the idea any further because of the lack of manufacturing technology.

Half a century later, a Swedish steam turbine manufacturer called Ljungstroms Angturbin AB appointed a new Chief Engineer, his name was Alf Lysholm and he was to be the pivotal in the development of the modern screw compressor. At that time, Lysholm was looking into lightweight compressors for gas and steam turbine use.

By this time the original patent rights had expired. Lysholm developed the profile of the screw compressor and tested various configurations and rotor lobe combinations. Not only was the shape of the rotors important, he solved the problem and patented the method for accurately machining the rotors. The 1935 patent clearly shows his asymmetric 5 female - 4 male lobe rotor design, although the shapes have been 'fine tuned' over the years, the screw compressor had at last been born.

Ljungstroms Angturbin AB changed its name to Svenska Rotor Maskiner AB in 1951. This company is well known throughout the world as SRM[1].

This type of compressor was designed, patented and manufactured by Svenska Rotor Maskiner AB(SRM) in Sweden in the 1930s, whose chief engineer was Alf Lysholm; this company still holds the patents on screw compressors. For years, because of the exceptionally high cost of machining the two mismatching convoluted rotors, screw compressors were used primarily on large stationary engines. Examples include the Elliot-Lycholm and the Broom Wade.




If ii didn`t own a turbo buick i would own a s/c mustang...maybe i will get a s/c mustang 86 fox body with 06 s/c power.

i liked the inter cooled superchargers.... the roush one still gets more than the whipple..

Just remember it's not all about power but how it gets to the ground and how the power is made. I'd personally get a Kenne Bell and do a front mount intercooler kit, but that's just me. The whine the Kenne Bell makes stands out, you can always tell it's a KB blower when you hear it coming at you.

i'd go Kenne Bell but thats only because i trust them because i know people who have them on their stangs and my friend Josh swears by Kenne Bell superchargers haha.. but i dont know much about the others... procharger ive heard were the best for fox-bodies but rousch chargers have always been around so i dont really know if they're better but they can't be that bad...

why a front mounted intercooler? why not one directly connected to the supercharger?

cooler and more dense air

what do you mean by more dense air?

cooler air is more dense than warm air. You really don't know much about cars do you? And you want an 05 stang as your first car?.....

Front mount is pretty much the only place to put an intercooler unless you want to chop the hood and do a top mount Ford GT style, but in reality they are not as efficient since you won't have the sort of cooling surface that you would with a front mount. Front mount you also have your movement pushing air through the fins on the core, taking the heat away better and dropping your charge temperatures anywhere from 50 to 80, sometimes 100 degrees depending on your set up and tubing type. Add on a methanol or nitrous spray system and you'll drop that even further. Plus front mount cores look pretty bad a$$.
