Hi all first time poster, long time drinker

has anyone had good experiences with aftermarket plenums
for the boss 260. I have seen some that look great but if they serve
no purpose then whats the point. i have seen a plenum with the intake
on the front instead of the side of the plenum, is the air distributed evenly that
way. has anyone found a decent price on an after market plenum.

is there a benefit with installing a throttle body spacer. i have done research
but nothing compares to the advice of someone who has experienced this
modification on the dyno. does it acctually slow down airflow and distribute the
air more evenly?

what is an underdrive pulley system and how can my boss260 benefit
from this modification.

are billet oil pump gears a must do mod?

the throttle body spacer and helix/phoenetic(whatever aye) spacers are really good paperweights. thats about it.

underdrives are a good noticeable mod, for the 260's use the correct balanced ones as there some cheapies that will explode your oil pump...

which bring me to oil pump. yes a decent mod if you are gonna push the revs past factory.. and basically why wouldnt you with a tune..
