loss of torque after K&N cone install!!!

[Chingon]

well, I finally decided to custom myself a k&n system with a cone I had laying around. I cleaned it, oiled it, made some installation hardware and plugged it in. Now, I did notice a big difference in power, but this was right after shifts....my car lacked the usual ..oomph.. from before...., is this at all normal? I'd expect loss of torque after changing exhaust, and the opposite after changing intake....

what's going on...plz:help

[PalmerWMD]

was it warm out when you ran it?

Fred..

[Altiman94]

probably all in his head.

[Chingon]

no it wasn't warm....hmmm, but then again, I pushed it the same as usual...

and it wasn't all in my head...

[180fan]

maybe too much oil and the oil got on your mafs? Only thing I can think of in the event of a real slowdown.

[Chingon]

maybe, i idid oil it quite a lot....but i waited the 20 mins of soaking time. And doesn't the maf work through heated wire? How would that influence it?

[yozsi]

maybe that k&n doesn't flow as good as you thought...

[Chingon]

well, shouldn't it be flowing better than a paper filter? My complaint is not a lack of power increase, but the power decrease..

Ahh good catch!

Fred..

[fuzion]

I would assume a filter wouldnt be at fault for a noticeable amount of torque loss, if any..

If you can really feel a difference maybe it's something else?

[Chingon]

well, now I don't know guys. I went to test drive a few times now, and it feels ok. But maybe I'm getting used to a power loss that is occurring? And back to the maf...how would it get screwed?

[titotonto]

No, he lost a solid 10 foot-pounds of torque according to thebutt-dyno

[Touchdown038]

Try putting the regular filter and box back on and see if you've really lost as much as you think you have.

Haha.

Anywho, whenever water, dirt, air cleaner oil, etc. gets on the mafs wire it will screw it up. Try cleaning it with carb. cleaner then take it for a spin.

will do, but my elec cleaner is at a friend house...and I have carb cleaner, but isn't that a little harsh?

[nismofan14]

No its fine. Take your filter off, start up the car, then while its running spray short blasts into the intake. The car will bog down and may sputter a bit. If it stalls, start it back up and start again.

Remember...short sprays to keep it from stalling.

[180fan]

The carb cleaner will have to be sprayed around the little wire coil if that's the part that got the oil residue clogging it up. Do not spray directly as they're fragile, around and not direct. For cleaning your intake piping, you can hose it down, but for the MAFS be gentle. That's something I learned from working on Toyotas, those sensors are very fragile and I always take that extra care with my 240 as well.

When I changed my stock filter to a K@N cone filter there was a noticeable difference i pickup...I guess this is due to less cold air going in and now you have warm air around your filter (engine heat) that makes it slightly slower...However, on the freeway I can feel an increase in top end power. When I switched back to my regular plate filter, I got my bottom end power back...

[Larry Pengilly]

K&N oil will affect a MAF sensor, the sensor uses a hot wire so to say. and that wire needs to main tain a constant temp. When air rushes past the wire the wire wants to cool down and the computer gives it a bit more power to keep the temp the same, that is kinda a short story to how they work, anyway when you get oil on the wire or anything for that matter it acts as an insulator for the hot wire and the air rushing over it doesnt cool it down and the computer has to input less voltage refrence and thinks there is less air moving over the sensor. I recommned a good cleaning with TB cleaner once a year. I do not recommend spraying them when the key is on you can damage it. Think of it this way you have a hot wire that is like ohh 100 deg (just a number folks dont quote me on this) and you spray a cold compressed liquid on it, you might break the wire kinda like a light bulb eliment.

I would remove the sensor and carefully spray the inside out with TB cleaner and then let air dry.

I have only seen this done on speed density systems, and the purpose is to clean the intake throttle body blades and AIC ports....

I wouldnt do that.

hope that helps

later

stock makes more tourque at lower rpm, try putting both on a dyno

[Trppen37]

wheres the intake sensor thing hooked up in?

[karay240]

if you're talking about the MAF, it's right after the air filter.

[Trppen37]

not maf....little sensor that was on the stock air filter box...

[Chingon]

only a few 240's came equipped w/it. California model s13's I think after 91 and some s14's I think.

[240_2NRman]

Listen to this fact....believe it or not.....k&N filters flow LESS than stock filters...it has been proven over and over again in research labs...we do tests on k&N filters all the time in my engineering program....9 times outa 10 the stock filter will flow better than the K&N filter. its just the name that sells.

[240_2NRman]

i believe that sensor is the IAT sensor

[p00t]

the more oil you put on the filter the less flow it will have, you are only supposed to moisten the filter element, not soak it.

read the directions... you spray the filter from 6" to 1 foot distance to wet it... 1 pass on each area. You let it sit for a few minutes then lightly spray any areas that are still dry. if you did more than this, redo time .

[Trppen37]

its the material being used...which brand of filter did u buy?? try getting a purolator or a deutch and let us know if it flows better?

[Chingon]

k&N original.

[xxtrizz]

geeze man just switch out the filter and see what happens. Putting in a better filter should not change the torque the maf would manage the air flow for you.
