dual air intake tube idea

[mookie]

just wondering what yall think about this idea, i'm hoping it would give me a smidge more power/fuel economy....

i am considering cutting the air intake horn off of a junk fj60 air cleaner and welding it to the front passenger side of my factory aircleaner ('86 FJ60) and then running the air tube out under the battery tray. there's a hole already there just like on the drivers side. surely someone's done this before?

i'm getting this baby ready to be my DD and baby hauler/mall crawler so i'm not worried about water and/or dust getting in from offroading

I think that you will be wasting your time and cluttering up your engine compartment on the passenger's side. I don't think you will see anything in the way of increased performance and will be bypassing the stock hot air intake (HAI) which helps provide warm air on start up. Keep thinking though..

 

[mookie]

i kinda figured that, though it wouldn't really be very hard for me to do.....and i don't care about cluttering up the passenger side of the engine, there's not much over there anyway......

i do realize that the primary restriction on the stock system is where it flattens out right over the carberator....pretty damned restrictive and nothing you can do about it except cut a hole in the hood which i'm not doing..... so i'm really not sure that more air coming in to the air cleaner would help any where it goes into the carb

I bet it would be REAL easy on a 62.
But yet again, I dont know if would even be worth it, other than looking different

i've read on here that a snorkle does help....... if so how could this not make a difference? double the cold air coming in?

 

[mookie]

well, i finally went ahead and did it.....it seems to me like there is a small improvment in throttle response and power.....i'll let yall know if there is any difference in fuel mileage

also, i shaved the tube off of the bottom of the HAI valve and welded a peice of sheet metal across the bottom of it, then T-d off of the vacuum line of the original HAI so that hopefully it will close the airflow of the new intake when it's cold, i'm not sure it that line pulls enough vacuum to close two valves at once or not....well see

Interesting ... you may be changing filters twice as fast though especially if you do alot of dusty trails.

 

[IrollwithTojo]

to you! Looks great

 

[Spike Strip]

Yes, interesting ... Nice clean job.

Let us know how it works out.

The new Scramjet Cruiser eh.
Could this be the real "AURORA" project?

thanks guys! it's my DD, i've got a beat to crap FJ40 for a trail rig so no worries on the dust

More cool air can only be a good thing, are you going to hook up the second hear riser?

 

[caserique]

This is my franken-setup. I just hacked off the housing and threw out all the tubing. I wheeled in the dust this weekend so the K&N is dirty but I'm willing to clean more filters for more air. So far cool winter driving has been awesome so we'll see how it does this summer. Oregon is pretty mild so I wasn't too concerned about the Hot air intake.

As far as power goes: big improvement over the behind-the-headlight-garden hose, especially in terms of immediacy. Gonna do headers soon to free up the exhaust.

On another note, why not run this blower on passenger side where the air is presumably cleaner and cooler, wire it to the ignition (I can't figure out when it's supposed to kick on but mine never did) and pump it directly into the intake hose?

 

[Yodafj60]

Your carb. cooling fan prob. didn't kick on because the wire to the sending unit got britle and broke off. Common problem. If you remove it from Drvs side location you may have problems with hot starts as thats what is for(cooling the carb. to keep it from vapor locking).

 

[caserique]

Ooh, thanks.

 

[Yodafj60]

No prod. You can do a search for carb cooling fan and find the fix for it. It's easy. I did the direct ground method and have had no problems. See ya.

 

[mookie]

TGonna do headers soon to free up the exhaust.

X2...thats my next step too!

 

[mookie]

are you going to hook up the second hear riser?

i did, check out the post with the picture in it for a description

 

[mookie]

well it looks like i gained a cool 1 mpg on gas mileage lol

Mookie-

a Toyota Hilux badarse once told me to just remove the large hose from the carb all together to get the best performance/power.

this was in colorado so really hot and really muggy wasn't much of a problem. (though it gets to be 95F there, the humidity stays pretty low comparatively).

i would suggest to you to at least try unattaching the hose clamps and taking the hoses off and seeing how it does without the hoses, if heavy dust isn't an issue (if you aren't driving THROUGH the mall when you crawl there) and you clean your carb regularly.

though this idea may be better during your "not hot, sticky, and muggy" season down there in GA...great idea, people in other parts of the country don't think like this.

Nice idea, good execution, great "Southern Engineering!"
