Title: extractor/header design?
Post by: SiKiD_01 on January 30, 2005, 01:08:13 PM

ok, can someone explain to me the concept or design of extractors/headers.

i have a set on my vit, but when i look at other 4cyl motors, the extractors are designed differently. i have not seen another one which is the same as mine.

ok, i haven't got a pick yet, waiting for batteries to recharge. but here goes.

usually, you have the 1st cyl and the 3rd cyl into one and the 2nd and 4th into another, and then into the exhaust and cat... etc. RIGHT?

i think mine is 1st and 4th cyl into one and 2nd and 3rd into another, then into the cat and exhaust.

what is the advantage/disadvantage?

thanks
Steve

They are normally linked 1&4, 2&3 to get the exhaust pulses evenly spaced. The firing order is 1,2,4,3 (or that backwards, I forget)
