Belt Drive Turbos
 
Recent models have been drastically reduced in depth which makes them lighter and more compact, thus easier to mount. Note the reduction in this first stage is a result of replacing the thick turbo compressor back plate with a thin machined aluminum plate. Reduction in depth is about 3/4".
Side view of 2.2 Mopar compressor with a new compressor back plate. Note both 1/2" (Compressed air/C02) and 3/4" (water) cooling blocks in these photos.
Note that the cooling block has disappeared and frame is even thinner by another 1/2". The whole cooling system is built right into the front bearing plate. You can see a lone fitting between the two bearing grease fittings on top of the bearings. The system uses a new cold air pneumatics source (or C02 where available) that is for more efficient even in a more compact package.
Another angle of the same belt drive turbo. These are cut and paste test models -- production models will ultimately be jig welded when several other new modifications are tested further.
Dale Long's 7.5 liter Ford Truck belt drive turbo has been upgraded with a new cooling block and an aluminum compressor back plate that weighs 12 ounces instead of the original 2 1/2 pound cast iron plate on the previous conversion. It also makes the blower about an inch narrower and easier to install.
This is a much larger belt drive turbo than the little 2.2 Mopar compressor model shown beside it.
The blower has now been installed on Dales 259 cu. in. Studebaker Lark V-8.

An early version of the high boost Gator Supercharger being built for 2-3 and small 4 cylinder engines. (motorcycles, snowmobiles, personal watercraft, All terrain Vehicles, etc.) It has 50,000 plus impeller rpm capability as shown with V-belt secondary drive, 80,000 plus rpm with ceramic bearings and flat belt secondary drive. Note that it uses a cooling block for the bearings, and has provision for using two V-belts, if required, for high boosts. A 2.2 Mopar compressor is shown here but larger compressors can be used for higher boosts. Note that its easy to add a second V-belt on the secondary drive if required for larger compressors.
Shafts, cooling blocks, and frames are being built by Gerry Drummond and Jim Glenn. This is the first batch. You'll note the long version which has space for a countershaft and bearings is undrilled. It will be some weeks before we've checked out several tensioner options -- but undrilled frames are available now for anyone wanting to go ahead with this model, using their own tensioner design.

A batch of Co2/water bearing cooling blocks
High boost versions use dual belts and cooling blocks. This supercharger is installed on a Chrysler slant 6, as shown here.
Our hats are $115.00 + shipping and we offer a choice of throat sizes --2",2.5",2.75",3" and height choices of 3"-4". We can make them taller if needed and we have made a 2.5" throat 2.75"tall version for a '67 Mustang with a Paxton. We can make almost any size needed but prices vary on the custom applications.
