so then... you have quite clearly contradicted yourself?
you say a turbo car can gain 2 to 4% in power by being in an area that is highly humid, and has "more air".
thats 2-4 kilowatts in a car that generally makes 100 kilowatts on the rear wheels. purely because of changes such as those mentioned by you and gary.
EISH!!! 😮 😮 😮
So this is true if he went from jhb to durban etc to get a dyno done. So that is area depending. I trust that he went to the same dyno in the same town. (all dyno's give different readings)
Its a bit of a hectic drive just for a test on whether he had any improvement with the mod. So visa versa if before the mod he ran on a dyno in durban and then went up to jhb he had a 5kw gain then it is reversed so that he overcame the minus 2-4% and made an extra 5kw. So 10kw gain 😮
This being true ill sell my moms stuff and buy a performance filter now!!
LOL - now i'm getting confused!!!
i was thinking about the filter thing over the weekend though, and the standard filters are good, even if its only for this reason:
- they are cheap and you can replace them often. so you will never run the chance of getting crap into your engine, because it doesnt cost much to replace!!!
i've had the cone filter on my for a long time now, and my engine bay is waaay dusty and dirty, but i haven't replaced the filter at all. yes you can wash them with soapy water, but what does it cost to re-oil them properly???
Just to clarify, I used the same dyna and both was done on very hot days with a 5kw gain on the wheels with the new filter.
VC, you gan buy kits to wash the filters and oil them, You buy it for around R160, my kit has lasted me for about a year and a half already.
I use a K&N cone filter and wash and oil it every 5000km and it has lasted a year and half so far and is still in perfect condition.
Where do you get the oil from for your filter?
You buy the kits from any accesory shop....it's a special oil and soap, you normally get K&N kits and napier kits for about R160
I got mine from Autostyle, R150.
So forgive my ignorance, (which is vast) Ill be in the market for a filter soon. Which filters are good?I hear names like bmc, K&n, hks, simota etc....etc. All the advertising from said companies give the same promises. I dont really trust what they say. how ever i do value your guys opinion.
Which ones offer the best reliability and most simplistic and easy to maintain?
I am a guy so i like the simple things in life that actually work.
Veecee, when i get my filter ill make one of those cold air boxy things and post picts and give you some ideas if you wish 😉
i reckon the easiest way to do it is to get the flat panel filter for the standard airbox.
either BMC or K&N will do. they are washable with the cleaning kits, and should last you a very long time. apparently they also give you a performance increase!
i've heard the sentra/sabre 200sti one fits! but i'm not 100% sure. i think Dr G has confirmed that in the past! he's a sentra/sabre boff, and he owns an very nice s13! lucky bastid!
MMMM yes th 200sti filter does fit....
the flat filters are generally cheaper than the cones. So this is a good idea. Is there any clue as to, If i upgrade turbo etc will the flat one & std box still serve the purpose? ( sorry this was not clear before.) What is the difference of the power increase between the flat one to the cone?

i think it will!
there is huge debate surrounding this topic, and i have lots of evidence (although with other motors) that the standard airbox with standard filter yields more power than either an aftermarket flat panel filter or a cone filter!
however, other people will give evidence that contradicts mine.
for the amount of power that we are talking about, i think you should just go with what you think is best, and what best suits your situation!
Thanx will do. So std box works, and when i upgrade the turbo i will do the necessary tests.
cool let us know, with dyno results if possible!
maybe we can almost settle the argument - almost!!!
Will do. 😉
