There seems to be some interest from Google for the supercharged MGs, who can blame you! Here we've a Lancia Volumex supercharged that was front mounted on an MG TA. This was a job I did for a good friend of mine, many moons ago. We ran the supercharger off the crank shaft pulley using duplex chain to join the drives together - we also had to use an 8mm hardened steel pin to keep the gears on the drive shaft intact. With the slack in the chain, there was enough give for the pop-off valve to operate - any less than an 8mm pin would break. From the inlet to the cylinder head we used a Shorrock inlet manifold turned upside down with spacers. I also fitted an exhaust extractor manifold which was wrapped in heat-proofing material to avoid fuel evaporation. This car needed a KI/gas pump to inject a little bit of fuel into the induction pipe when the starter button was hit. I don't recommend supercharging this way, as the induction pipes are far too long - but if like my friend you insist on a front mounted supercharger, this may just be the way to go about it. The car produced about 6lbs of boost at 5,000 rpm and is still running today (some 10 years later!).
