airdoc question

[High Five H2]

So, I got my airdoc in the mail today and I went to install it. My dad came out and helped and said that I should send it back. the tube gets really close to the radiator fan, 2 or 3 mm away at the most. when the engine revs or if I'm off roading it, I'm afraid that the engine with bump the fan and damage it. we looked at trimming the elbow tube where it attaches to the throttle body and rotated the oval end around, but that 2 or 3 mm was as far away as I could get it. the stock intake is a good 1/2 inch away.

Any thoughts? Has anyone had problems with this? I'm going to keep it because I'm looking at getting an E-fan and that one doesn't look like it will hit the tube, but until then I don't want to risk it.

Read your instructions. Narrow end should be vertical. Make sure the other end is flush and tight on the throttle body! Once installed and tightened rotate fan blade by blade and verify distance between blade and AirDoc at closest point. Each blade should clear 2-3/16th (I believe, don't quote me on that) verify your instructions. Mine does. Been on there a good while and no issues. The fan blades seem to be too thick to flex

Anyone have a copy of the instructions for the V8/Alpha airdoc intake that you could email me. Mine didn't include the instructions.

Sent from my XT1080 using Tapataint

i'll scan and send them tomorrow. thanks abntroop.

 

[ABNTROOP]

No worries, if not post up again and I'll dig for mine and upload them. I think I've got them tucked away somewhere

Mine was close to the fan too. Just take a dremel and shave down the plastic fan with a sanding bit. I have an efan now but I used the airdoc with the clutch fan for over 3 years

I've been running mine for 3 years and zero issues. I did trim the corners of the fan because I was paranoid like you.

Under high torque, the engine actually moves away from the fan area. No worries. My clearance was about 3/16 and it has never hit.

 

[High Five H2]

just thinking out loud here, but what if I took a sanding block and turned the engine on and used that to trim the fan blades? I'm worried that if I trim the fan wrong that it won't be balanced and it will wear out the bearings and stuff.

 

[ABNTROOP]

That sounds like a bad idea. Too many ways for that to go wrong IMHO

 

[High Five H2]

man i asked my dad for help and he's making me paranoid about every aspect of a stupid intake. i don't think trimming off 1/8 inch from the fan will make it unbalance.

 

[ABNTROOP]

I doubt it either, just don't do it while it's running, unless you Hate things with all your heart....like fingers

 

[High Five H2]

i'll just try the dremel thing (with the engine off) then I guess.

 

[ABNTROOP]

Pffffff! P*ssy! :giggle:

Plenty of others are running it here with no issues at all

When I built my intake for my 08 I built it similar to the one I made in 06 for the I-5, but of course for the V8 it went to the front.
I used a small enough tube and transition boot to allow more room than some designs I have seen since then.

From flow bench info and the existing measurements I decided this would be adequate for the V8.
I remember it being about 1/2 inch or more.

I was concerned about contact as well when offroading but there does not seem to be much movement.

Seems to have worked for 70,000 miles.

 

[High Five H2]

did you angle the throttle body up some?

 

[Hunner]

No, as far as I know that would not be possible.

I just rotated the 90 degree turbo boot adapter to line up and used a smaller size tube.

This is my design so it is not what got developed later, even though I did share my sizes at the request of the other builder.
I did not pursue this as I was concerned there could be some issues arise from it's use.

Then GM came out with one that pretty much squelched that.

ok, i played around with the tubes until they looked pretty far away and I filed some of the fan blades off. not really enough to make a difference, though. turns out, I didn't have to. I read in the instructions that you need 3/16" clearance. I had at least that. I don't think there's anything to worry about.

 

[Renagade132]

Yes mine mounted on perfectly on my H2, I attached a K&N filter to the head, and added a bracket to keep it from moving or shifting around

If you filed the blades down and they aren't exact size all the way around. You might create a wobble which will possibly take out the water pump and clutch.

any filter recommendations? I'm scared to go to an oiled filter because they aren't so good at filtering, especially in really dusty areas like where I live.

I run an oiled k&n filter on mine, 50k miles, no issues except for a rougher idle (more black stuff get stuck on t.b.)
Added an oil catch can to reduce the oil that sticks on the t.b. so that I don't clean tge t.b. as often.

I live in the desert and do desert runs (kinda baja style) once a week. I run with 5 jeepers and they all run a ram-air style intake with k&n filters, none of em complaining.

 

[High Five H2]

I got the oiled aFe one. they probably perform about the same, but it's a prettier color.

I guess if it wrecks my engine, I'll just need to buy a DD and then do an engine swap, right?

 

[amrg]

How many miles do you expect your engine to last before needing a rebuild? And would the rebuild be due to the filter or other reasons?
