| Here is some info on the lysholm Supercharger that I bought for the 944. It seems that it will be extremely well suited for high boost applications. Of all the types it seems to be the most capable at adding a massive volume of air but it also seems that it has a negative draw of HP all the time. WHO CARES. The Positives will more than outweigh the negatives according to my Supercharger Counterpart on the Mazda Forums.... The Lysholm supercharger looks similar to a helical Roots blower, but with rotors that are far more twisted, and have a conical taper. The result is that these "screw-type" compressors have an internal compression ratio, making them more efficient in high-boost applications. One disadvantage of this internal compression ratio is higher parasitic losses during off-boost operation. A Roots blower can be bypassed with a simple butterfly valve at part throttle and the only drag will be the mecahnical movement of its gears and lobes (which accounts for only about 0.3 hp according to Eaton). A Lysholm compressor, on the other hand, will continue to compress air as long as it is being turned, even if a bypass valve allows that air to be recirculated. The only way to eliminate a Lysholm compressor's parasitic drag at cruise is to let it stop turning via a clutch. (Ironically, the Eaton Roots blower used by Mercedes-Benz uses a clutch instead of a bypass valve, despite this being the more complicated solution. Mercedes does things its own way.) There are currently three companies building Lysholm-type compressors, all in Sweden. One is not imported to the U.S., another is sold here as the Whipplecharger, and the third, Autorotor, is integrated for automotive use by several tuners It's a good thing that my 944 isn't being built for Fuel Economy. SUPERCHARGER STUFF I started to work out the location of the supercharger a bit better. As you can see, I have it hooked to the ceiling to support the weight until I get a bracket made. I will attach it to the motor mount and the engine block. The entire assembly will be able to move Front and back for fine adjustment. I need to keep the outlet straight up because of the way the oil is fed and retuned to the Supercharger. Once the supercharger is mounted, I will figure out where the alternator is going to go. One Problem at a time. ![]() ![]() I got some time to put the parts more or less where thy belong. I'm not going to get into much detail but you will get the basic point. I'm totally impressed worth the Parts from GT-Racing, They are expensive, but the fit is great, they are strong and most important. They weigh close to nothing. The Nose panel is a bit stronger than the fenders, but I understand that it is the leading edge of the car and I'm happy that it is stronger at to cost of a bit of weight. The Headlight conversion is just placed there. There is clear plastic the covers the bucket. I'm simply waiting on the 951 bumper shocks and then I'll fire it on the actual car for a better test. I do not think I'll be disappointed. ![]() ![]() ![]() ![]() Tested out the basic look of the car. I'm like a kid with a new toy. Got bored and ripped more of the Porsche interior, seats and carpet, in Prep for Bodywork. The more I get done now, the less time it will need to be prepared at the shop. Time is Money... I also got the 25L fuel cell today! ![]() ![]() ![]() ![]() ![]() |

| The entire front of the car has converted parts for the 951 style fiberglass from GT-Racing, Literally are 6 Lbs Steel Bumper gone for the 951 Aluminum. The Headlight Motor and Linkage are gone (Fixed Headlight Conversion) The Hood is being swapped out for fiberglass The rear seat and the interior dampening under the carpet have been removed including The deadliner Hard Rubber cover that lines the interior of the car. The Heater and A/C complete are out of the car leaving a hollow dash. The fuel cell has been removed/replaced by a 5 Gal, as well as all the lines and pump/filter. Rear Carpet with Stupidly Heavy Rubber Liner Gone. Fuel level sending unit gone. Power steering Pump and lines gone. Battery is being replaced with a 5 Lb battery. Stereo is removed, Passenger seat is out but can be replaced. The stock 16" rims are back on. Wiper Delete, Steel Exhaust is being replaced by a short. Under the fenders Porsche lined the car with a thick rubber coating. Removed Auto Central Lock, Power Windows being swapped for crank. Trunk Popper removed and replaced by a Cable. Cruise Removed. Misc Brackets... Now Things like the Carpets and Seat are Removable and Replaceable so it will still be very drivable as a summer car and will retain the Oh So Sexy look of a Porsche. The plan is to use Black Speaker Box Carpet and Contact Cement it directly to the metal all over the rear of the car where the back seat was all the way to the trunk. If done properly, it will look Ok but weigh nothing.. Here is the basic idea for the 944 Fuel Delivery. The car is capable of unreal cornering that will only be better when it's 2100 Lbs. I have designed a system where the fuel will not slosh to one side during hard cornering. The 5 Gal will feed a 1 Gal with Double outlets. This will serve as a "fuel buffer". During cornering even if the fuel in the 5 Gal is on the side of the tank, the 1 Gal will still be full. When the car goes level again, it will top up the 1 Gal. The second Fuel tank is on the way with the Stainless Braided Fuel lines. ![]() Ok, SO Here I finally have both together. I still can't believe the difference Bore Over Stroke makes in an Engine. Mazda Piston - 4 Banger Small 2.0L Long Stroke Porsche Piston - 4 Banger Large 2.5L Short Stroke I believe that the Porsche piston is just unreal. I know that there is nothing Magic about the Word Porsche. The engine is still able to break, you can still kill it with PSI and Bad fuel management. I just think it's very cool how well it is designed to last and be driven hard. ![]() ![]() ![]() Got tired of the lighting in the Speedo. Replaced them with 9 Blue LED.. The picture catches harshness that is not apparent. Looks great and I have more to iluminate the Autometer. ![]() ![]() It's about time for an UPDATE I think... Lots of little things have happened since my last post. I have found out that I am moving to Ottawa this spring... 1200 Km to Ottawa. The 944 has to be able to Run by July 06 so I have to put the Paint on hold. The original idea was to have the engine compartment the same color as the car and that was going to be done the same time the car was painted. Now I am in a rush a bit and I have found a solution that works for me as well. I bought 100 Sq, Feet of B-Quiet Aluminum coated engine bay noise killer. It's Sticky on one side and aluminum on the other. When heated it is easily applied to the firewall with a roller and looks stellar. So the entire engine bay will get lined with this material. That gives me the freedom to paint the car without having to take out the motor again once we arrive in Ottawa. Here are some pictures of the Deadliner. ![]() ![]() I got the badly abused center panel of the stock Recaro seats recovered. The center panel used to be Super 1980 cool ORANGE, but I think that the Black Looks super. ![]() So You all remember the headlight conversion... ![]() I installed two Hyper White LED bulbs in each as my DRL.. ![]() ![]() ![]() This is also finished.. The Driving Light Holes were removed, backed by fiberglass and filled level with bondo.. ![]() BEFORE ![]() AFTER ![]() March 07 2006 This might make the entire Engine Bay Idea a bit clearer. It's far from finished, I am getting the first layer on and then I have a second roll to make it stronger in places and cover up some stuff to make it look nicer. ![]() ![]() March 09 2006 Started major work on the interior. The Headliner is being replaced and starting from the front to the rear it got half done but then it started to be too cold to continue. Tomorow is supposed to suck so later for pictures.. Today I bid on an won a 944 S2 clutch as the original one that came off my 944 was down to the rivets. Out on a limb a bit, the S2 clutch is diferent looking but I think that it will be compatible with the stock Flywheel and pressure plate that I have. The deal was too good to pass up.. E-Bay Link I think for $60.00 it's worth it.. Quote:
Here is a shot of the work. You can get a feel for just how low and long this car really is. The frame is sitting about 3" Higher than normal because the motor etc... is not installed. SEX ON WHEELS Can't wait till it's done. It's a bit cold today so not much going on in 944 Land. ![]() March 12 2006 What great weather to work outside! Today I finished the headliner. The old one simply sucked and was ripped to shit. I used the same material that was used to recover the seats. I think it looks great, All the edges are covered and the material is thight and not coming down any time soon. Here are some Shots.. ![]() ![]() I got the last of the heavy cracked and useless "Factory Noise Killer" off the inside of the car and replaced it with the same light weight aluminium that I have been doing the engine bay with. The Old stuff was 20 Years old and had split all over so it was useless and heavy. Not a good combination. I'll post up some pictures of the finished product as I get them.. Here is the bare metal. ![]() 06 April 2006 Update. Motor going in this weekend... Interior Rebuilt.... Both doors open and the trunk works now.. :) ![]() ![]() ![]() ![]() April 11 06 Updated picture of the Weekends work. There are some Misc bolts holding stuff together that are the wrong length on the Fuelrail etc, and most of the sensors have to be hooked in but the hard part is done. ![]() May 07 06 The Back End Is together.. ![]() The Fuel Cell is going to fuck alot of people up. It's totally visible.. :) ![]() 14 May 06 Fiberglass Fender Fitment and Installation ALL DAY.. They are solid and are about 6 Lb rather than 60... Wicked! ![]() ![]() ![]() ![]() ![]() |

| May 20 2006 Today got the bulk of the rear the way I wanted it. I installed a manual release handle behind the passenger seat. When pulled, it opens the rear glass hatch... Basically... 1. Less Wiring 2. Less Weight 3. Less "Something To Go Wrong" Works like a charm. The thick black carpet has been replaced with the same stuff I used throughout the engine bay... It is going to cut down on the "Green House" problem of the 944 design. I only did the left side today but you get the point.. ![]() ![]() ![]() ![]() |

| May 29 2006 Fuel System is finally coming together. The 5 Gallon has two AN8 Steel Braided lines that hook to the 1 Gallon tank. Each of those is hooked to a Tee fitting. One goes to the engine and one returns. Basically, even if there was only a gallon of fuel in the car, it would be almost impossible for it to starve for fuel around a corner. This was done solely to save on weight. The beauty is that there are no different settings or configurations for holding more fuel. Simply fill up the 5 gallon and your set. The fuel lines are AN-8 (One Inch Steel Braid) through the fuel filter until they reach the MSD EFI Fuel Pump. Then the lines are stepped down to 3/8" steel braid, they travel the fuel rail and run 3/8" until the collector where the lines get stepped back to AN-8 and connected to the in port of the 1 Gallon Tank.. ![]() ![]() ![]() ![]() ![]() |

| May 31 2006 Fuel System: The Double Feed is hooked up. The two feed into Tees that go to the front of the car, One is Supply and one is Return. The vent line at the top is to make sure that the 1 Gallon is full all the time and the one way check in the system makes sure that noting will spill out. Next up is the Filter, Pump and Fuel Rail. ![]() ![]() ![]() ![]() |
