Ford Crossflow Magnuson m90 eaton supercharger

We had a customer who had purchased a supercharger kit that was fitted to a Ford 4.1 aluminum headed crossflow engine in a cortina. The engine used a 2 barrel manifold that had been modified to accept the supercharger.


As the carburetor was mounted a long way from the supercharger we suspect that pooling could have been a problem as the draw through system had the carburetor placed a fair distance from the supercharger.


There are many superchargers that have been designed with an internal bolt pattern that can be difficult to bolt on to manifolds where access to all 4 corners to bolt down the blower. The AS0068 is bolted to the internal holes in the base of the supercharger and has 4 external mounting lugs.


The AS0016 Aussiespeed Cross flow 4 barrel manifold has had the angled carb pad machined flat so it is at 90 degrees to the crankshaft and will also allow the mounting of the supercharger as low as possible. The AS0067 wedge adapter can be bolted or welded in position so the supercharger can be mounted to the intake manifold with the 4 external hold down bolts. We dont have the supercharger and the drive as the customer is in another state, we have done all the machining that is required and it will be a case of getting the alignment right then drilling the holes for the hold down bolts and adapter. We manufacture steel spacer rings to move pulleys for the crankshaft if the alignment needs adjusting.


The Aussiespeed AS0067 is cast as a wedge and can be machined to get your desired height and to get the blower at 90 degrees to the crank. it can be mounted with counter sunk bolts or welded to the manifold.


The 2 adapter plates sitting on the manifold. Additional grinding of the plenum to remove the internal lip may be required once the adapters have been positioned to match the drive length.


All supercharger manifolds should be fitted with a backfire valve to help prevent damage to your supercharger or intake manifold incase of a misfire. The AS0016 has been machined on the side of to keep the backfire valve in close as engine bay room on the cortina is a bit tight.

Dual 4 barrel Carbs

Aussiespeed is always looking at new products and to complement our range of performance intake manifolds and supercharger manifolds a new range allows inline 6 cylinder and at a later day V6 and V8 guys to fit twin 4 barrel carbs to most engines.


Some will say why would you want to drown an inline 6 with dual 4 barrel carbs ? An engine needs air and fuel needs to be metered to match the airflow and 2x 600 Holley vacs set up with the secondries either disconnected or with ultra heavy springs the engine will only draw what it needs. Sure this set up isnt for a stock 161 Holden engine but with the right engine combo it can be tuned and give you a wild looking intake set up.


Holden 9 Port 2×4 barrel Aussiespeed intake manifold will accept Holley 390 upwards squarebore carbs in north south or east west mounting.

Ford 250 crossflow manifold

With 5 different manifolds in the dual 4 barrel range for the Ford 6 plus the blower intakes and 2 and 4 barrel carb intakes Aussiespeed have the largest range of Ford 6 cylinder manifolds.

Supercharger Intake Manifolds

Its been super busy down here working on our new range of blower manifolds to suit a very large range of inline 6 cylinder engines.


We have our test fit engine an old Chevrolet 250 Cubic incher that was removed from a Chevy pick up. Once we remove the brackets and extra pulleys give it a wash and a coat of paint we can start the puzzle. We plan on 3 options supercharger wise. The Weiand 142 or Weiand 144, M90 Eaton from the L67 V6 Buick or super charged Commodore if you are in Australia and the M112 Eaton that was fitted to engines around 5.0L.

Our Products in the USA

We shipped 2 Aussiespeed Endurance go karts to the Briggs & Stratton Motorsport facility in Milwaukee in the USA. The karts are to be used for engine testing and for displays at trade fairs and go kart events through out the USA and Canada. It was great to see our Aussiespeed banner hanging in the Briggs & Stratton Racing testing station along side outher great companies and brands like Summit racing who are also distributors of Briggs & Stratton Racing engines to the Junior Dragster Fraternity, Amsoil manufactures of Briggs 4T Amsoil 4 stroke small engine racing oil available @

The Briggs & Stratton 4T is now available in Australia.


Aussiespeed AS0139 Carb adapter

With so much going on here at Aussiespeed we have decided to bring all areas of the business to one central location. With an expansion into the supercharger market for not only early model Holden, Ford, Valiant inline 6 cylinder engines over the next 12 months you will see many other new products to suit some of the later model engines also being added to the Aussiespeed performance product range.


This is the top of the pattern for the new AS0139 2×4 barrel carb plate. It mounts dual 4 barrel carbs on to the Aussiespeed supercharger manifolds or any of the Weiand or B&M manifolds that accept the 142 or 144 supercharger. The patterns are at the foundry and we hope to have castings back at the end of the week. The other thing that may appeal to inline 6 cylinder owners is for that look of twin 4 barrels on your inline 6. When set up and run with dual 465 vac or 600 vac Holleys in either north south or east west position with very heavy secondary springs the engine can be tuned to operate like a single 4 barrel engine. More updates soon.
