I have a afe stage 1 and was wondering if it would be worth it to upgreade to the stage 2 or some other system??? Thanks for any input or ideas??

 

[slowleak]

make your own intake. way cheaper. and do the ccv mod. ill get some pics in a bit of my half ass intake.

I had a DIY intake for years and it worked great. The only thing that got me was when I put on my AE I found out that my intake air temp was over 200*. Then I decided to get a real intake and get the AFE stage 2 since I like to drag race and I sled pull.

So to make my long story from above short. Get the AFE stage 2.

What was the intake air temp (manifold air temperature post intercooler or intake air temperature) after you changed to the AFE stage 2.

 

[skylinedan]

Ilike mine, It's a bit loud at hwy speeeds, say 70 + . but I would never go back to anything else.

im sure i would like it too, but im just not rich enough lol. i do as many things diy as possible.

What was the intake air temp (manifold air temperature post intercooler or intake air temperature) after you changed to the AFE stage 2.

In Redding, Ca, 105* ambient, my intake temps were running between 198* and 215* with an open air intake system.

In Sonora, Ca, 98* ambient, my intake temps were running between 110* and 120*.

AFE stage 2 with ZooDad mod was the only thing I changed between events.

 

[BDRUMMONDS]

Isn't the only difference between the stage 1 AFE and the stage 2 the cold air box and the torque tube? the Torque tube is avail from many vendors and the cold air box can be fabbed out of some nice 3/16 sheet, put some weather stripping on the top to seal against the hood and youre good to go.

[slowleak]

yeah im debating fabbing up a box to see if it helps. 80* temp difference seems like a good bit. strokin what type of temp sensor/setup do you have?

 

[strokin_early_99]

the stock temp sensor. I use AutoEngineuity for data logging info.

the stock temp sensor. I use AutoEngineuity for data logging info.

I do too...

In 85* temp, at idle I'm seeing 135*... as soon as I start moving it quickly drops to 100*

This is with the tymar on 2 different trucks with identical setups (01 F250's, Tymar, 4" mbrp, DP Tuner etc..) and NO zoodad mod.

 

[NWSUPRD]

I like the Tymar intake too. The afe stage II will make a big difference also. I have a stage I in the barn if anyone is interested.
You will get a ton more air moving from the stage I to a stage II or something large.

 

[jtharvey]

Howard, those numbers reinforce my urge to get an AFE Stage II when I get my H2E setup. Thanks for the info.

That temperature drop is great but it doesn't make much difference unless it makes the post IC temp change. Get some post IC temp readings with different intakes on your truck. I would be very interested to see what you find.

that may take a special pipe...seems like i saw something about an afe2 to
h2e pipe on a dealers site

 

[jtharvey]

Yeah, it does. ITP has it, all ceramic coated and looking nice! Hell, it's just more money...at this point in the mods game, what's another couple hundred dollars?

 

[Slated4Greatness]

I have the AFE Stage2 and the "Jat99" tube (The jet hot coated pipe from ITP) and it rocks! Yeah, ok I can't quantify because it was part of a completely different setup.

IMHO: If you are going with stage 2 or above injectors with a higher than normal output turbo then you might want to step up. Less than that it's just not worth the extra $$$

 

[Cat_Rebel]

We all run homemade Tymars & they work just fine for what we do.

 

[jtharvey]

IIMHO: If you are going with stage 2 or above injectors with a higher than normal output turbo then you might want to step up.

I guess my B Codes and plans for an H2E would qualify me for that then.

I've got the homemade Tymar on now, and it does work fine. I'm wondering if there's something better than "fine" though. Like Howard, I've been watching my intake air temps with AE. They run along the lines of what he stated.

MAT temps may not change as much, but lower temp air being pulled in before the compresor has to help. I would like to see some MAT data of 6637 (Tymar filter) vs AFE II though.

With the little 38R on my truck as a single a while back in Winter I dropped about 15 or so trucks in about 20 or so minutes a number of wich were stacked dodges and 12 valves making more power than me.

The biggest issue with that little 38R was efficiency spinning at 40lbs of boost being driven by B-code fuel.

But, with ambient temps in the teens/20's I had ice cubes coming across the compressor and the same ice cubes blowing through the cooler. It was running stroooooooonnnnnnggggg. Strong enough that about half of those truck's owners were still waiting for me in the parking lot when I got to the pull just to figure out what in the HELL was going on with that 7.3, even after I stopped at the ATM and all.

Ambient temp plays a very big role in power output. Denser air in, means denser air in the cylinders all else constant.

I eventually wouldn't mind building a duct system that ducts air from the very front of the bumper up to an airbox where the pass side battery goes. That way it would not only be cooler air, but there is almost certainly a measurable high pressure zone in front of that bumper. Every little bit of Pressure Ratio help is gravy.
