Title: Re: Some SU questions
Actually I made functional trumpets out of the original pressed-metal intake horns in the original orange backing plate by just steel-brazing some thick welding wire around the outer edge and filing it smooth for a good radius. They worked, there was induction noise, I also used a K & N filter element in the original housing, and drilled some extra holes around the edge of the housing.
Cheap and very effective.

Thanks for the info Terry, I have found some trumpets that are pretty much the same length as the ones in that ghastly orange plate (probably safe to stick to for the time being I imagine), should get a nice induction noise now too :o)
BTW, How much should a pair of Webers in reasonable nick cost? What about an inlet manifold to suit? Cheaper than the current quote of $750 ea I hope!

Tom,
It is safe to vent the outlet from the rocker cover to atmo, by law you must fit a baffled filter which are available from most speed accessory shops.
Can't answer the second question re SU's as I don't use and don't like em but for webers it makes a huge difference and I imagine that any side draft would benefit from tuning the intake to a varying degree. If you go from a restrictive air cleaner to a more efficient one remember to re-tune your mixtures as the immediate effect will be to run lean which is expensive if not corrected

Hi list
I have an incredibly ugly air filter on my 1.5" SU's, and would like to replace it with some trumpets and tubular-shaped air filters. Sorry for the been-answered-a-million-times-already questions....
Is it safe to vent the outlet from the top of the rocker cover and the two outlets from the carbies to atmosphere? How does the length of an intake trumpet affect the power of an L-series engine?
Thanks :)
- Tom
