Supercharger? Might rustle a few feathers!

[macmattom]

<font face="Comic Sans MS"><font size="2"><font color="blue">I <b><i>MIGHT</i></b> be able to get my hands on a Shorrock B75 ([?]) supercharger with 1.75" carb mounts. Would this be able to be adapted for a TR7 (16v or 8v head) and if so, is it worth the effort or cost? I'm not going rushing in, but it might be a welcome addition in a year or so [:D]. Hold on to your hat, mother, she's gonna blow!!

Seriously, just thought I'd see what sort of discussion this prompted, and we'll go from there</font id="blue"></font id="size2"></font id="Comic Sans MS">

The pheonix rises from the ashes - just give it time!

Just bear in mind a few things<ul><li> the block can handle ±200BHP without tearing itself apart</li>
<li> blowers have a tendency to sap quite a lot of power from the engine, so make sure you have a positive power gain, which shouldn't be difficult</li><li> Blowers are much better (reliable) than the average turbo </li> </ul>
And they are great, if properly set up they give a very good spread of power [:D]
On the other hand, to get to the engines (power) limits, you don't need a blower or turbo ...

I have a modern Eaton blower on my 1955 MG Magnette and it transforms the car. Lots of torque from about 1500RPM, and you don't even notice any power loss from below that point.
I would be inclined to look for a modern blower as they are more efficient than the old Shorrocks and Judsons. Parts are available and they are very reliable.
I have thought about this myself and with the TR7's canted engine you would have the ideal place to mount the blower up wher the carbs are normally mounted.
Here is a pic from the front of the MG engine with the blower mounted. Imagine the blower flipped to the other side of the engine. Of course you would have to fabricate an intake manifold but that wouldn't be all that difficult. [:D]
