History - When racers first started putting Roots superchargers on their automobile engines the blower of choice was the 6-71 series blower off the side of a Detroit Diesel inline 6 cylinder engine (71 cubic inches per cylinder). This blower case was 15" long and everyone used the standard inlet size because everyone used stock cases with modifications to the end plates. At the time the 6-71 was big enough (or so everyone thought). We all knew the 8V-71 had rotors that were 1" longer but the 8V-71 case did not fit our manifolds. Someone came up with the idea ...

... of making a 1" spacer to bolt between the end plate and the blower case and use the 8-71 rotors. It was a great idea but a little bit fiddly so someone made up a pattern and started casting their own blower cases to use the 8-71 rotors. Once it was learned how to build and machine the cases the next logical step was to make longer cases but there were no rotors long enough to work. The idea came to slice off a bit of rotor (1") and make the peg that goes in the end of the rotor for the bearing a little bit longer so it still goes in to the original part of the main rotor and let the " 1 inch rotor slice" slide up on the bearing shaft. Now with aftermarket cases being able to be made any size the 10-71 was born. We were still using stock GMC cast rotors as billet rotors (like now) were not available because the availability of 5 axis CNC machines was rare with only aerospace companies having such capabilities. When the 10-71 was created the idea was to open the top more for the larger blower. Here is when the 10 Top blower was created. The opening was expanded for the bigger blower. Then since the 1" rotor slice worked so well as most racers will do now lets try a little more and another inch was added creating the 12-71 and then on to the 14-71 at a 19" case. At 19" long the two piece cast rotor was at maximum length with a 15" standard rotor and a 4" slice added to the rotor. Now ask this hardware to turn 13,000 rpm as a lot of us did. This was the maximum for the cast rotor situation. It was at this time the proliferation of 5 axis CNC machines were around and a few companies started making billet rotors. I tried a billet rotor 14-71 blower but found them to be no better than the cast rotor as far as performance. I think the cast rotor actually went a bit quicker as the increased boost of a billet rotor blower "cost" too much power to make versus the power it gave me. The old standard 60 degree rotor blowers were reasonable performers at lower boost pressures but got less and less efficient at higher boost pressures. You must remember the original application (the side of a two stroke diesel) the blower only made a couple of pounds of boost just to help the two stroke engine move air through the engine. After the PSI blower came on the race scene and the fact the 5 axis CNC machines were a lot more plentiful, the blower manufactures started making better more efficient blowers by changing the twist of the rotors from 60 degrees to 120 degrees. Then later with 120 degree billet rotors a 16-71 blower (20" case) was created in an attempt to keep up with the PSI or Whipple screw blowers.  Now what was all this about...? I wanted to explain the difference between a 8 Top blower (6 or 8-71) and a 10 Top blower (10,12,14-71 and 16-71) We all know now that the big opening on a blower does not flow more air, in fact less, but there are a lot of blowers around with a 10 Top hole and a lot of injector hats with a 8 Top hole.

All Bugs have a 8 Top hole.
Some Bird's have a 8Top hole and some are 10 Top Birds.
All Buzzards have a 10 Top hole.
All Barndoors have a 10 Top hole.


8 Top Hat spacer (raises the hat up to make it easier to get to the hat nozzles) also improves air
flow into the supercharger. PN 35020-28650


8 to 10 Top adapter. Connects large top blowers to standard 8 Top hats.
1/2" Part Number 35020-28281
5/8" Part Number 35020-28282


8 to 10 Top Hat adapter used as a nozzle rack for better placement of nozzles. This is a 14 nozzle hat arrangement. When the injector hats were first made the blowers were only 15" long and had no Teflon or nylatron. It was felt then that 8 nozzles in the hat were enough after all you had 8 cylinders didn't you? Seemed to make sense then. What about now with the blowers being much longer. It is a good idea to keep the rotors wet on a roots type blower, especially if you have a Teflon and nylatron blower as the clearances are tighter and the blower needs more lubrication. Keeping the rotors wet will make the blower last longer and the blower will make more boost too. Don't you need 12, 14 or even 16 nozzles in the hat? It is not that you put more fuel in, you just spread it out so the full length of the rotor gets fuel. Is that not a good idea??
Fully Adjustable Barrel Valve HERE

We keep the hoses, nozzles and nozzle holders in stock to convert your system.

Call us at 0411-699 535 (In Australia)


Fully adjustable barrel valve - Hex link only sets the stage volume. This allows you adjust the stage volume with out changing the idle volume. You can reference this with the space between the two pins. As you change the hex link, the relationship of the pins change, you can measure that reference that to what your 60 foot times are.

We can modify your barrel valve to suit or supply you with a new bolt on unit.

The 31 Chapter 200 page Fuel Injection book is here for  more info on what has been called "the best fuel injection book on this planet". Now only $99.95AUD If you only learn one thing it is worth it
The FI book has been this price for ten years now, my publishing costs continue to rise and soon I will have to raise the price.
Currently all orders are processed at the old price of $99.95 - don't miss out - order now.

I must point out that my printing house (and all the rest of them as well) have raised their prices so when this last printed batch of books are gone... the price goes up. Order now and save.
Can I point out it is less than 50 cents a page!!!


We ship the FI book inside Australia COD Australia Post. When the order arrives at your post office you pay the postman and he sends the money to us. Outside Australia we require a valid credit card to make the charges to.
