We are pleased to announce that our 'Volumex 7 Fin' outlet manifold is now available although because we have deliberately designed a manifold with a low outlet pipe profile to avoid complicated cowl modifications, this means that the rear U-tube support system has to be located in the bottom of the chassis rail. We are willing to release our manifold to customers prior to announcing completion of our new mounting kit (chassis castings and U-tube), which will be available very shortly. It will be essential to use our rear support mounting kit only with the 'Volumex 7 Fin' manifold as other designs are non-compatible. Our rear support mounting kit will however, be suitable for a wide range of blowers and manifolds available elsewhere. The manifold is supplied in a semi-polished finish.
A well thought out design has now produced a manifold with a wide range of benefits to the enthusiast.

The Design Benefits of Our Manifolds
The 'Volumex 7 Fin' outlet manifold is the only manifold we are aware of which is designed specifically for use on C, J, P and L Types without the need to incorporate any modifications/welding to the manifold itself. It may also be suitable for the other models.
To provide a brief insight into the main features we are incorporating;
- The outlet bend is set at 90 degrees (i.e. travelling parallel with the chassis rail to fit perfectly between the radiator and chassis rail itself in order to avoid unsightly kinks in pipes commonly seen). We have made the outlet pipe section especially long to simplify the induction pipe connection to the engine. It will also look better with the hose positioned higher up out of the way.
- The 90 degree elbow bend has a secondary benefit in that it provides a neat rectangular space between the rear fins and the mounting plate in which to position a period looking rectangular oil reservoir.
- The underside of the manifold incorporates a diamond boss for those wishing to install an inverted secondary blow-off valve close to the blower.
- The inclined angle of the outlet pipe is set at 14 degrees to nicely clear the blower crosstube support arrangement whilst leaving just enough room for the rubber hose connection.
- The main body of the manifold incorporates 7 slender cooling fins which are designed to compliment the 7 cooling fins on the Volumex supercharger case.
- The top side of the main body section incorporates a period style MG logo. We have used the same logo pattern we used for the ENV manual gearbox case badge. It is therefore made to the MG factory size and layout. If there is demand, we may also produce this manifold without the MG logo for other makes of car using the Volumex.
- The 7 cooling fins have a 5/8 inch corner radius and in our view presents a period look.
- The manifold pattern is a split pattern in order to provide a casting with excellent finish quality. The castings are of LM6 and have a uniform wall thickness of 5 ½ mm making for a light casting for its size and although the outlet manifold is larger than the current Volumex manifold available elsewhere, our pair together are ¼ kg lighter and as mentioned previously, need no modifications.
The 'staggered' Volumex carburettor inlet manifold has been designed with careful thought. A centrally positioned carburettor flange can create problems with the positioning of the T4 float bowl and the position where the dashpot appears through the cowl. Our new 'staggered' manifold moves the carburettor back by circa 1 1/8 inch which in turn radically reduces the need for untidy and complicated modifications to be made to the cowl itself. In summary, our manifold improves aesthetics and ease of fitting. It can also help protect the carburettor from potential impact damage.
Supplied with a 3 ¾ inch diameter circular flange and bored to 1 5/8 inch diameter although customers can request a bore up to 2 inch if necessary. The carburettor mating flange is machined as a blank and ready for the customer to drill and tap to compliment their choice of carburettor. Thickness of casting is circa 1 3/8 inch.
