89 22re with the 82 Supra AFM

Can I mount the AFM sideways? I'm thinking I can since there isn't any fluid involved but I was talking to Bigbluepile about mounting options for the Supra mod and was stumped when he asked if there would be a problem with the little flapper thing if I mount it sideways.

Thanks.

 

Are you thinking like there would be air from going down the road pushing it open further then it should?? I wouldn't think it would be a problem since you have the filter on there. or else we would have heard more folks with 3rd gens that did the "deck plate mod" complaining its screwing up their performance.


on a side note, did your LCE header ever give you a CEL? I have the normal one everyone else has had (freeway, constant speeds) but I can't pull a code, so I checked my Supra MAF for resistance and the 3rd and 6th spots gave me a reading of 530 ( FSM says 20-400) Wondering if you ever checked your Supra MAF, since I know you said you came across a dead spot on the first one.

 

I didn't get any codes with the header nor did I ever check the MAF. I still have an odd dead spot and I'm almost 100% sure it's the TPS so I'll be pulling it, cleaning it and checking it as soon as I can track down a meter.

As far as why I asked the question about the mounting of the MAF I'm planning on mounting it to the intake plenum over where the throttle cable is and it will be hanging sideways. This way I can cut a hole in the hood for the filter and get air that isn't all hot from the engine compartment.

 

Interesting project. And you were a little geeked out when you drilled into your top to mount the rack, just imagine when it comes time to cut the hood!!!

 

Man that hood is all jacked up anyway. I'll be happy to punch a hole in it for the air filter. I'm even going to order a set of marine vents to install in the hood over the top of the header to vent heat so there is going to be more than one hole cut that day.

Oh and I freaked about the top because I was afraid to let water in there.

 

No, I was concerned with the fact that the flapper drives a flat spring that normally sits horizontally to the frame, lets say. I though maybe due to the weight of the door against the spring might cause idle issues or hard starts or something. Kinda why I didn't tilt mine when I bolted it to my new filter box.

on a side note, you should have bought a Downey... HA!!!

Anywho, I measured the resistance specs on my Supra AFM when I got but used the 22R-E specs due to the fact I could seem to find any FOR the Supra. I figured that if it was plug-n-play that those values "should" be the sameish...mine were all good. Junkers might have a good point though on cleaning out the TPS, god knows when yours was cleaned last!!

 

why dont you just get a pair of those AFM adapters, and bolt one on each side of the hood; one facing down into the engine compartment, and the other facing up, sandwiching the hood sheetmetal between the two with maybe a home-made gasket on each side between the adapter and the hood sheet metal

then run some duct tubing from the inlet of the AFM to the adapter facing under the hood, and then put the filter on the adapter facing up out of the hood

then you wont have to worry about having the meter on an angle and you can keep in it's stock orientation and bolted down somewhere

 

I guess you are right, about the MAF that is, there might be constant stress on the spring in either side mounting scenario. It seems like you might wear out the spring faster, but hell, it is a 28 year old spring.

And HEY! how bout you clean off that Downey, god knows when the last time it had a shine!!

 

lol! That's funny 'cause I was googling "how to clean a ceramic header" the other day!

 

interesting thought, how would you make a release so you could open the hood with a metric butt ton of extra hose?

 

I think he's crazy...

 

Adapters? For what ever reason I have no idea what that is.

The other reason for mounting the MAF to the intake is to free up the original battery location so I can either put the battery back there, install another battery or use that spot for on board air or something else with a +10 cool factor.

 

At least my header is clean..

 

*edited* Let me rephrase that last post...

 

You mean one of these above and below the hood, right??



And I thought you were originally going to mount it right side up on top of the intake manifold?

 

Damn I need one of those for mine!

 

Again I have no idea what in the hell that is.

I still may mount it on top of the valve cover, hell it'd be an easy plate to make and mount but then I have to find some huge scoop to cover it. Might look cool for a while with it just sticking out of the hood. Or....... I could take the hood off and run it like I'm some sort of nut with a blower on there.

 

Well to get back on topic...Mine is mounted sideways currently and I'm not experiencing anything odd. The connectors are on the bottom side so it fits under the hood. She runs fine...but again I must say. When I got her she ran like poo and for all I have done she runs 10X better. May run better if the AFM is sitting right maybe not. I'm happy with her so far.

 

yeah those adapters like pictured above is what I was talking about, lol

 

Looks like Lumpy has the right answer, unlike 'bleeder...
