The Whipple SuperCharger is by far after months of research the best choice in Superchargers for a 454SS. They work very hard to accommodate all needs of your truck and have up to 50% Horsepower increase right from the start. They sell a kit that includes all you need to put the Whipple Supercharger on a "STOCK" 454SS bigblock.

I started looking into superchargers about a year ago. There are three that I considered for my truck Whipple, Paxton, BBK/Eaton. The Whipple appealed to me since it was a package deal "ALL INCLUDED NO OTHER PARTS NEEDED". I wanted to do the work myself and we all know what it's like to have to manufacture parts, brackets etc. another reason that I liked the Whipple was that it is a twin-screw thus power from the launch to top end with no lag in any area. The Whipple came with all we needed, We did seem to come short on vacuum line but all was done for about $4.50 more than the sticker for the Whipple Charger. The total cost of the whipple was $3500.00 including shipping. It came within days of ordering and Dennis (A rep from Whipple, Nice guy and very helpful) was on top of the purchase and delivery and all questions that we had. Whipple seems to be a small company, They close for lunch.

After convincing the wife that I "Needed" it... Uh Had to have? Well guys you know the story. I ordered it and had it on my truck and running in a week, understand that I am a shadetree mechanic and installed this with a friend (Kim Robison Thanks Kim) after work and on a weekend. Kim was allot of help everthing from tool boy, Photogropher to booda. I of course had to have a few other buds to help lift off the bed (discussed later) Darin Schmeeckle, Mike Coffey, And my wife(For what its worth) Whipple claims that the Whipple Charger can be installed in 10 hours. This could be true but I took my time.

Let me stress that these are not instructions on installing the Whipple
SuperCharger, We have skipped alot of steps in this information file.

We started the installation with laying it all out in the garage, yea, Next to the weedeater and lawnmower taking every precaution to keeping the area and charger as clean and free from dirt as possible. I have a few tables in my garage just for laying out new additions that will be added to the 454SS. There is alot in the boxes(3) that they send with this supercharger kit so I need allot of space.

	The First step on my list was to remove the bed to get to the fuel pump, some people say that its easier to drop the tank but from experience let me tell you to remove the bed. It will take a couple of buddies but you can do it, its faster than dropping the tank. The radiator also needed to be drained.
	Looking at the tank you can see the round locking retainer that houses the fuel pump, Its pretty easy to get to. It all pulls out and easily replace the pump. BTW: Whipple recommends that you use only 92 Octane or better after the installation. I use 93 and also use an octane booster.
	We removed the stock pump and installed a furnished corvette fuel pump and fuel sock. we have at this point already installed a fuel pressure gauge under the truck just past the fuel filter, this will be used in a bit to test fuel pressure.
	After the fuel pump was installed and checked we then started the disassembly of the air filter assembly. also removing vacuum lines from the throttle body taking note of there original location! You also need to remove the injector wires since its a little hard to remove the throttle body with them plugged in.
	You still use the stock throttle body adapter and manifold, you have to countersink the throttle body adapter plate's front two holes to be able to get the Whipple adapter plate to sit flush on the throttle body adapter plate. I know... Here we are using two adapter plates to adapt the Whipple to the manifold. Strange but it works.
	After we removed a few more things like the EGR, coil/coil brackets and throttle brackets, we installed supplied braided flexible fuel lines. We removed the radiator hose and thermostat housing and added the new angled thermostat housing and went ahead and put in a new thermostat that I paid for. We then torqued down the Whipple's adapter plate to the throttle body adapter plate.
	after placing the small rubberband like seal(O-Ring Material) on the Whipple adapter plate (Pictured above) I placed the Whipple onto the whipple adapter plate. I look manly doing this I am sure but let me remind you this thing is not light. It took some balance to that. This is a real touchy thing here. Whipple says to use white grease to hold the rubberband seal in place, this thing once you set it down its like on ice. Slippin and a sliden.
	After installing the new radiator hose and hose protector, moving brackets removing the the fan belt and a few other miscellaneous things We then began to install the throttle body to the Whipple, The throttle body sits at an angle on the back end of the charger. This is sorta strange but hey, it works.
	We secured all twelve bolts on the Whipple to the Whipple adapter plate to secure it. Installed support brackets and new tensioner in the new location installed all new pulleys and new belt. at this point (Not pictured) we replaced all vacuum lines to throttle body and added any other items that needed to be installed including a new map sensor throttle position switch.
	All of the brackets, pulleys, belts and some of the vacuum lines are in place here in this picture. In the picture you can also see the heater hose that is routed through the Whipple on the back plate close to the throttle body. The radiator was then refilled with water/antifreeze.
	The Whipple Supercharger comes with a K and N air filter but! they do not send you cleaner and oil for it, you can pick that up at a rod shop or somethin. This was installed along with all of the support tubing and brackets. this all fits together really nicely.

The Whipple Supercharger was in all fairly simple to install using most tools found in my tool box, there were a few things we had to pick up but for the most part we had it all. We only had two snags with this installation, One was a bracket that was sent by Whipple was drilled incorrectly, We called them and they overnighted us the correct part. I dont frown on this at all since they were so helpful through the whole thing, Two was at the time of installation I had a 700R tranny, The kit from Whipple was for a STOCK 90 model 454SS and that meant a 400 tranny. So we had to manufacture a bracket for the shift cable to the throttle body. I have since replaced the 700 with a 400(Thats another story).

Introduces The Twin-screw Supercharger

The "Whipple Charger" is not just another roots type blower, it is a state of the art screw compressor. Screw compressors by design have much higher volumetric and adiabatic efficiency ratings than roots type blowers.

Volumetric efficiency indicates how well a compressor or blower breathes and how much leakage occurs. For example, if a compressor or blower has a displacement of 10 liters, but only 7.2 liters are discharged, the unit has a 72% volumetric efficiency rating. A compressor or blower with 45% volumetric efficiency must have twice the displacement to pump the same amount of air as one with a 90% rating.

Adiabatic efficiency pr overall efficiency indicates how well a compressor or blower uses the energy put into the drive shaft. A unit with 100% adiabatic efficiency would convert all of the input energy into compressing the air without heating the unit or the air. High energy to pump the air. It also indicates that the power losses, through heating of the air and the case, are reduced.

Simply stated, the optimum compressor or blower should have high volumetric efficiency to minimize the displacement and physical size of the unit, as well as high adiabatic efficiency to minimize power drain from the crankshaft. The "Whipple Charger" will fill both of those needs.

The screw compressor was designed and patented in the 1930's by Svenska Rotor Maskiner AB (SRM). SRM has continued to develop new rotor configurations for the screw compressor and currently has over 100 designs protected by patent. Today the company has 32 licenses in 23 countries around the world. SMR is the world leader in screw compressor technology.

Here is the partial list of U.S. licensees: A-C Compressor, Ingersoll- Ran Co, Carrier Corp, Sullair Corp. Colt Ind. Inc. Thermo King Corp. Dresser Ind. The Trane Corp. Dunham-Bush Inc. Vilter Mfg. Co.

The owners of SRM, Opcon AB, have formed a new company to develop screw compressors for the automotive market. This company is Autorotor AB. Whipple Industries is the exclusive distributor for the automotive after market in North America.

The SRM Twin-Screw Compressor Concept

The SRM twin-screw compressor technology has been used in industrial applications for more than 40 years. This compressor technology is outstanding in means of durability, compactness, efficiency and capacity. It's draw-back has up to now been the manufacturing costs.

Today new high volume production technology has reduced manufacturing costs to a competitive level. The working principle of the twin-screw compressor is shown below.

The compressor has a built in volume ratio and thus also internal compression that is the main reason for the high adiabatic efficiency, even at high pressure ratios. It is possible to design for pressure ratio's up to 4.0 in one stage. The compression takes in all rotor lobes simultaneously. The rotors are synchronized with timing gears.
