velocity stack filters..

[pandaah]

just curious about what design or what type of filter looks best... what have you got?

[DreadAngel]

You can get individual socks, mini pod filters or a filter that covers all the throttle bodies inline

Appearance though is all personal preference...

I personally rather an sleek airbox than open trumpets but that's me

[ed]

i like unifilter for flexibility of custom sizes etc if you wanted individual socks for each trumpet. highish maintenance, but reasonaby priced.

i know people hate them as well, but they get my vote

my engine, however, has proper airboxes

[pandaah]

yeh sounds good i might google unifilter and see what i find, i know k&n does them but i would prefer trumpet stacks with a filter inside... thanks anyways guys!

I don't trust any foam filters. I've seen way too much dirt get through foam filters.

Air box is the way that I'd go. If that wasn't an option, then get a paper/cotton type filter that surrounds all trumpets.

Paper filters don't interupt the design of the trumpet, whereas sock filters and those clip-on end filters would.

[pandaah]

yeh but it affects the look =P .. might just end up going individual miniture pod filters

Unifilters for me.. never had a drama with them, but its not a daily driver and they are covered when the car is stored.

really what is the point of having velocity stacks if you are going to have a filter inside them , its the shape of the stack that creates extra airflow so if you stuff a filter inside it you may as well chuck the stack completely and save your money

velocity stacks are designed to increase airflow and dont work with a filter on around or near them if the filter changes the airflow to the stack itself. Most ofthese things are used without filters in one off races where the engine is rebuilt after ie F1 through the years

They really arent any better than the spider in your cabon fibre gear nob if you use them with a filter

you may as well just use K&N filter pods on a pipe , cheaper and actually prevent shite getting into your engine

^^^^^^^

eh? filter inside the bellmouth?
i doubt a properly designed & installed sock is going to fuck the flow character in the manner youre suggesting. sure, not perfectly the same as an open trumpet, but the bell will still function just fine.

Actually... Marchschnell does have a point... I've got a set of T3 VS + Unifilters, which I haven't fitted yet, as I purchased them before thinking it through properly and talking to tuners...

Apparently, and this is what I was indicated by various tuners, the filters remove all benefits of having properly tuned VS... You might as well just stick pipes on there, and you will get the exact same power figures than if you have properly design VS with the unifilter filters.

To get optimum performance out of your VS, you will need to get a desent size airbox covering the VS, with one single airfilter (If used for road driving).

Racing purposes are totally different... Under randing condition, you have constant airflow going through the engine bay, and hence, having Open VS is OK, none the less, most run without any filters as it's a controlled environment anyway.

Road driving... well, you have dust, as well as long periods of idle while moving in traffic jams, etc.

i call bs....

AFAIK the drop in performance when pulling sock filters over the end of
your stacks, is mainly due to resistance to airflow. The filters don't have
enough surface area, so the pressure drop is high. There will probably
also be some minor interference with airflow patterns, but the foam should
help by stabilising the airflow and aligning it with the end of the stack.

Unifilters for me.. never had a drama with them, but its not a daily driver and they are covered when the car is stored.

Pandaah can i ask what car its for? If its for any 1st Gen Celica id say stay away from the UniFilters above. They are extremely high maintinance, need them soaked in petrol atleast one a fortnight as they get very dirty very fast.

If it was me and i had the money.. Id piss the VS off and just buy these for each carb. They look very well presented imo.
