Any example of a lysom supercharger used on a factory car?

Whipple Charger

Originally Posted by Whipple Charger
If you’re interested in building your own supercharger packages for kits to sale to the general public, or if you’re building a custom application, there is no better supercharger than a Whipple Twin Screw Compressor. OEM manufactures utilize positive displacement superchargers due to their incredible throttle response and drive-ability of a big cubic inch motor. When building a system for the consumers, you must provide a very broad power band with a high peak horsepower level, only the screw compressor can give you this. This is due to the high adiabatic (up to 80%) and volumetric efficiency levels (up to 98%). The Eaton/Lysholm screw compressors are the most reliable, dependable, performance-enhancing item ever designed for either low boost or high boost levels.

The screw compressor is by far the best supercharger available today; it’s the only supercharger to provide a positive displacement design for maximum low-end torque as well as high efficiency for maximum top-end horsepower. No other supercharger in the world can offer the same unique benefits. Centrifugals and turbos have tremendous lag time during shift points, on-off throttle and off the line boost. Roots-type superchargers have been proven to not be very efficient, especially at higher boost levels. Whipple Superchargers has a variety of screw compressors for all types of applications, anywhere from a 1.2 Liter compressor to the 3.3 Liter compressor. Whipple also has a wide assortment of drive lengths, pulley combinations and bypass valves for all types of applications.

very very very nice read ... after reading that twin charge setup it almost seems like you would be prolonging the cars life by running at an almost always lower inlet temperature ... no? to top it all off our cars have an intercooler so having said that wouldn't the end result be an even cooler 20psi to the engine? (well using the example it would be 19 psi after hitting the supercharger intercooler ...no?)

Remember two things...


1. Can your engine Handle 20 Psi... Never unless you build it

2. Is it worth all the extra weight and the pulley or could you do the same thing with one big turbo...

It's a very cool idea for a showcar but even though it proves to be impressive at making HP, it's very complicated when compared to just a S/C or just a Turbo.

The parasidic drain of spinning the S/C is a bit of a negative plus the additional weight of all that **** is just too much.

Can we agree that in reality, if the same car was simply turboed at one Psi more than the Turbo/Super and the intercooler was made a bit bigger to compensate for the heat, it would be a better performer.

My point is this, if it was that good, we would all be doing it.. NO?

Believe me, I am not "Poo Pooing" the idea, it's wonderful to think way outside the box sometimes...

wait now im lost at this intercooler deal ... the air to water intercooler that the ss uses ... does that mean that there are two intercoolers??? wasn't there a video that showed how the super charger works and in the video wasn't it an example of the inter ... inter cooler? does that mean we have two? sorry im feeling really retarded with so much info flying around ... where am I?

Only One. It is more compact and easier because you don't have to move the air to the front of the car, just Hot Coolant...

The intercooler cools the heated air charge before it reaches the engine, increasing the density of air to increase power and reducing the propensity of detonation at high rpm and high boost levels.
There...

There is one intercooler mounted in the intake manifold under the blower that the compressed air flows through. The coolant that is pumped through the IC is sent to nothing more than a radiator to the front of the vehicle, not a seperate IC. So its more like the SS has one intercooler and two radiators

ahhhhhhhhh so the effect is more cooling than one or the other by itself?

Now for the big question here: Did you actually write all of that all by yourself? Or is this just a good copy and paste job?

I'm a mod on several forums and I have been working on that series for a year or so here and there. If it wasn't me, then I quoted it...

Know what would be really cool... if everything in it was fact based, instead of having blanks (things you know nothing about) filled in with oppionions, your's or whomever's. Besides that pretty good write up.

ROTREX SUPAECHARGER

New New New Shizzy..

Here is what I could get...





Traction transmissions require relatively large engagement forces between traction surfaces to prevent slippage. The ROTREX automatically adjusts the contact force, to optimize the gear for the current torque required for the situation and application at hand. This means a reduction in frictional losses and wear of the transmission. Where full torque is transmitted, the transmission has the capability to provide sufficient traction force to prevent slippage.

Characteristics


· No high speed bearings needed
· Based on standard components
· Power transmission by traction engagement
· No noisy toothed gears
· Robust and durable by design

The Rotrex patent may be applied to gear-designs in various ways.

For automotive applications three gear-families are currently manufactured:

Why don't you look up some more facts about the stuff you have no idea about? Like my ghost made mention of.

HAHAHAHHAHAHA This is one of the funniest things ever said on this board. Do some research... start here procharger.com.
