The V8 Owners Forum -

for my third ever milling machine project - i thought i would aim high and try boring out a rover plenum. After creating a few jigs i got it on the machine and bored it out without any problems. I couldn't get a 71mm plate so i made one from flat sheet, then turned it on the lathe.



Came out really well - i'm very pleased with myself. I think my old dad would of been proud.

Few more pics on the rover manifold archive:

nice one Elliot

mmm 71mm twin plenum

Just reading your page about RV8 inlet manifolds in general, I have some pics of EFi manifolds, including GEMS towards the bottom of this page:

Feel free to pinch them.

Finished photo's.






I can machine them out for £100

Nice idea, when I fabricated my front entry plenum, I used a TB off a Vauxhall Senator/Monza, it was a ling time ago, but I think the bore was either 71 or72mm, plus it had the added advantage that it was a bolt on TB

That's what i was going to do - so i thought i would have a go at machinng out - if it didn't work i would cut it off and weld something else on.
