Depending on length it can produce a much smoother flow, some say a bit of a
ram effect which increases power and torque . Longer stacks as in longer
runners means more torque while shorter ones mean more power. Not lots, but
it all contributes to a freer flowing intake which helps your freer flowing
exhaust to make a bit more power/torque and slightly better fuel economy.
You note vintage racers usually have anywhere from2.5 to 6 inch stacks. Some
with a stocking for a coarse filter, most just hoping nothing of consequence
enters the throat. I have a set of 2.25 inch stacks in my 3.25 inch K&N's on
my MGB and they seem to help. Just the ho hum stock setup on my Magnette.

What is a stub stack? Would it allow for a filter that lies closer to the
engine than a regular pancake filter?

Hi everyone,
I'd like to get a pair of 1.5" H4 stub stacks and I've tried emailing Steve
Ash several times to see if he would make some more, but I haven't got an
answer from him.
So... from a light scour of the internet there appears to be two types
available at a reasonable cost:
$32.50 ea -
http://www.aptfast.com/ShowItem/101221%20Billet%20Alloy%20Stub%20Stack%20SU%
20HS4.aspx
$57 pair - http://www.rimmerbros.co.uk/Item--i-RL1396ALT
I've excluded the K&N ones as they are very rough, by all accounts.
Are there any others that people would recommend?
They're going to fit inside K&N filters that are 2 1/8" thick.
regards,
--
Robert (in NZ)
