Short trumpets, Rover V8...

[wedg1e]

Hmmm. As I have my induction plumbing in bits, I find myself contemplating the length of my tracts (oo-er) and wondering what benefit may be had from shortening them? My engine is in a mild state of 4-litreiness, fast road cam, manifold/ heads have had some porting work, uprated FPR, short valve guides/ double springs, flap-type injection. Any advantage to short trumpets on such an engine, if so (and ignoring the technicalities of how to extract them ;-) ) how much would be a reasonable amount to lop off?

Expecting a slating...

Thanks for that, chaps: I was thinking more along the lines of pulling them out and cutting the bottoms off, rather than Joolz barbaric chainsaw-massacre solution ;-) I do have SOME engineering sympathies, you know!
How about short trumpets AND a plenum spacer, then? At what stage do you have to go for big airflow meter, throttle body and space shuttle fuel injectors?
I was thinking more torque rather than more power, incidentally.

Tim, what £££ for some carboniferous trombones?

Ian The Airflow meter and injectors (Jaguar) are a good idea, offering more torque if you can't find any i probably have some tucked away somewhere that you can have cheap, Larger throttle probably not worth the expense, My Superflare trumpets ( which come fitted in base on exchange basis) are £250, A 390 would respond well to these upgrades.

Mwuahahahahahahahahahahahahaaaaaaaaaaaaaa.........


...but define cheap? (Off-line if you prefer)
