Cold-air intake and fuel economy Volvo 850s (non-turbo)

Hello,

Can cold-air intake yield a small improvement in fuel economy on a
1997 Volvo 850 (non-turbo)? Would fuel economy improvement sacrafice
performance?

What would be the best ways to go about adding a cold-air intake?

Thank-you

 

All of the Volvos I've dealt with already have an intake snorkel from
the airbox to up in front of the grill. Seems the one of the first
things performance nuts do is mess with the airbox but the factory setup
is excellent. If you want to maximize fuel economy make sure your tires
are filled to the max pressure, remove unnecessary cargo from the car,
and run synthetic oil. All of these things will have a greater effect on
economy, particularly the tires. Driving style has a huge effect as well.

 

Its all advertising, you wont notice a difference, if you took all the
milage claims of all the different gimmics sold your car would be
getting 1000 mpg by now, but non work. Hydrogen generators are the
lastest scam

 

It's best to inflate the tires to 10% below the max listed pressure,
both to avoid gauge error related damage and to give an acceptable ride
with the higher economy. If the handling seems too 'touchy' at 10% below
max, try 15 or 20% below. I've been running tires at 38-40psi for many
years.

 

In my opinion the most important single factor reducing fuel
consumption/distance is the grey jelly-like mass sitting between my ears. Just
consider that every time you brake you are converting mechanical energy (for
which to get you had to burn about 3 times the energy amount as fuel) into
useless heat, means practically burning your money into smoke. Your driving
habits is what mostly influences fuel consumption, if the rest of the car is ok.

i think the question is if one of these new electric superchargers
will work. yes & no! yes, they will provide a real intake boost.in
fact my ME friends find them infinitely superior to mechanical
superchargers. the trick now is to intercool them efficiently. once
they're in production, Geeley (Haaaaaaa......) will bring them to you.
no, YOUR ecu is too old to make seemless use of it. the simplest
required modifications would be changing the timing & using higher
octane (Myst races on 102 & is eco-sensitive on 96, both w/ a BTU
boost {how did they do that? do you have a very,very,very long
time?}).

but i race. for ordinary purposes Volvo weighed & balanced a number of
factors. they then built a beautiful engine. you can't save money by
changing it!!! if i tell her to Myst will get 13 km/l, but i'm ripping
her apart -- esp on the track. i'm saving up for a complete rebuild
this winter maybe sooner, you have no idea how much all those ti
widgets cost. i'll consider myself lucky. formula 1 teams consider
themselves lucky if they get 1 race.

finally i'm w/ the smart man who responded earlier. just do the simple
stuff & the rest will take care of itself. do maintainance as per
Volvo spec. most of the rest is snake oil -- i own a snake or she owns
me, we're not quite sure. she has no body fat. syntec is better. is it
more cost effective? probably not, but it is more forgiving. if i talk
air filters, we'll just have an argument. however; new & clean is
better than old & dirty. if you drive in a # of different enviroments,
consider having different air filters. if you intend to keep the
vehicle a while you won't end up buying any more filters. you will
learn to identify need for replacement by inspection, not mileage.
tyres? well it's a trade off. better traction means worse mileage.
