I have twin SU's with ram tubes, and foam filters (with the big springs inside).
I've heard that foam filters arent the best and i was thinking of maybe getting 2 pod filters instead.
Which would be better??
The carbs are suck though on a turbo set-up.

So the pods dont use foam filter medium? Do they use a K&N style filter?

the pods you can get in foam, k&n style stuff and paper....i'd stick with the current set up personaly.

Test them...hook them up to a vacuum guage ( very accurate one) or make a manometer....test drive car and see how much vacuum is sensed behind the filters (at full throttle)...remove the filters and test again...there shouldn't be too much difference..if there is you need a bigger/better flowing filter.

I've heard the foam type filters (which you have currently fitted, Mike) are the least restrictive of all of those mentioned. The advantage of a Pod Filter is cool air, but with your current setup you've got ample anyway IMO.
None of them will really make a substancial difference though, you can experiment etc but those panel filters can cost a lot more than they're worth. Just my two bobs.

Thanks for the info guys.
I only had some concern over the filters when i went to get it engineered, the engineer said the engine will be running too rich with foam filters, i said i would get it tuned, and he said it didnt matter. (for those of you who may have read my thread on getting my car engineered, i did say he said a lot of things i didnt agree with). Its not engineered with foam filters, i used an airbox to pass engineering.
Thanks for clearing that up.
I wasnt concerned so much about gaining extra power, than i was about my engine not running correctly. So i will stick with the foam filters.

i wanna know what the bguck makes people think pod filters make the air cooler....THEY DON'T!!!! all they do is suck hot air and add 500 ricerwatts to exels...

i know on bikes that most of the time a less restrictive air filter will make it run lean if anything...
foam is pretty free flowing, tho its probably the worst at filtering.. not too much of an issue if you clean then very regularly
do you recon the air box setup you used for engineering it was less than ideal? id probably stick with that setup and use a K&N drop in panel filter (about $100rrp)... saves any hassle from mr plod
tho pod filters might look a bit better, and sound nicer

Depends if the foam filters run as an oiled setup or not. Personally, I think your engineer has his head up his a..rse. As was said, do a flow test, failing that, if anyone can measure the MINUTE difference in the air flowed I will buy them a beer.The priority here is stopping the crap and dust from getting to the pistons and rings, not anything else. IMHO.

LCBOI, some one wrote in a ricer magazine that pods are the go, little did they point out it is sucking the hot air produced under the bonnet by the engine therefore actually making the car produce less horsepower, but if it is print somewhere, all 18 yo ricers say it is gospel, you are excluded from the above reference as you are actually a 43yo but in a 17 yo body!

The post about bikes kicked my brain into gear...
If all else fails at least comon logic should prevail!
EVERY motorcross bike I have owned since I was 12 years old has used a FOAM FILTER....
Now you can't restrict the breathing on a 2 stroke at all they just won't go.
Motorcross bikes are designed to be ridden in extremely dusting environments, they are also designed by small Japanese guys whpo have more brain power than most of us collectoively can muster!
So I'm with the Japs... Foam filters all the way.
Not as sexy as a K&N but a lot less $ and they do the job.
I use them on the race car and my bores look fine.
Cheers Greg..

are they oiled foam filters? couldnt see a foam filter stopping much without oil... its like snot 
my road bike came from the factory with a reuseable oiled foam filter, as do basically all kawasakis
if you find its too lean then using a little extra oil can help richen it up too

seriously...people going on about how great pods are is one of my absolute pet hates....grrr....suppose the few of us older (nyuk nyuk) car nuts use lodgic to work out it's all not true.....

most ricers in the know would put up some heat sheilding around a pod, and duct some cool air around it
but really, when you can just drop in a K&N panel filter and open up the holes in the stock air box, why bother...
