Autoexe forced induction airbox...
 

Just wondered if anyone had any experience with this box...

This is similar to the way aftermarket CAI for the M3 are made...plus with all of the talk about performance gains with the ram air effect....this looks like a good alternative for me without having the need for ducting...

The only concern I have is if it will fit in the space of a aftermarket airbox and clear a ASP medium intercooler.

AND if the CAI opening will clear the ASP duct...

and the instructions showing how large it actually is..

https://www.rx7club.com/forum/attach...postid=2641140

does it fit in the slot the IC gets it air or do you haveto cut some plastic to the left of the IC ducting area for it to fit in?

Tim

wouldnt it be called a cold air intake mod, instead of a forced induction? after all, the car is turbo charged, and i dont think a ram air intake will be able to force enough air for the turbo.

when did they release this for the FD?

Tim,

I'm not sure as I have never seen it in person and was having a hard time navigating on the autoexe website...
but if you look at the instructions in the second post it looks like it just lays ON TOP of the stock intercooler duct...no cutting needed...

but with the ASP medium I am worried that it wont fit either on top...and maybe tight on the side.....

the reason i mention this was that Zerobanger was able to achieve higher trap speeds (I think) with ducting to the airbox vs. without. Also, I remember Damian making similar mods to "duct" directly to an aftermarket CAI to get a "ram air" effect.

I have NO idea if this will do the same but I like the thought of this setup better.

these pics should help:

ya they do!

do you have any feed back on this product? is it considered to function pretty well?

What kind of filter element is used?

and where the heck did u find that pic?

another:

hmmm looking at that pic makes me think that it won't clear the pipe from the turbo to the intercooler on the ASP medium...

Doesn't look like you'd be able to use the ASP intercooler OR duct with this intake - it just takes up too much room. I'd suggest an M2-style intake:

Based on the pics I'd say that intake will only fit with the stock IC or an IC that doesn't come with it's own duct, using the stock crappy one. Again it appears just like the stock setup stealing air from the IC to use for the intake. So essentially a waste of time. I am of course basing it entirely on looking at those pictures and assuming it's attaching to the top of the stock IC duct just like the stock airbox does come to think of it. I could be wrong.

yea that's what I have right now...

I was just trying to find something alittle better...

guess I will just have to work on my fiberglass/ducting skills

RIIIIIISE FROM YOUR GRAAAAVE!!

I reopened the thread to get more input on the autoexe intake box. I hope you guys dont mind.

Here are more fitment picks...

As you can see, it works great with the stock intercooler, nothing new. purerx7 did provide me with a pic with it working with the greddy SMIC. I checked the measurements and it looks like it will work on the M2 medium as well (M2 is .5 inches wider). Im not sure what duct you can use (M2, stock or fabbed) but I think it pulling air from the top will work.

Its really really big.

Curious to know if that intake will work with any of the FMIC's out there.

Well either way I will report back. I have an M2 Medium SMIC and will be getting the autoexe intake. Probably get it installed in sept. :(. If anyone has more info that would be great though.

wow back from the grave....I am probably going vmount with the knighsport kit.

I think the M2 medium is about the same size as the older style pettit coolcharge II? Anyway, I wonder if it would work with the pettit? I have the pettit intake and have even added a thermal barrier between the radiator section and the intake, but it is still pulling very hot air into the system. This looks like it might at least START with cooler air.

Is this really $1100.27?

i have a thought the feed type 2 bumper or any bumper that has the extra slot on top has anyone ever fab up a way to maybe make it like the autoexe to connect to it and have fresh air going to the intake?

Attachment 718806

Interesting idea fd3s.

Existanz, the intake isnt that expensive. If you look around, you'll see that even at places that usually carry higher priced parts are under 1100. I think all of the local importers here have the part. As usual, I sourced from purerx7.

i plan to find a feed type 2 bumper because i think its a sexy ass bumper and i been wanting it, and it just popped in my head for awhile now, and this thread made me say my idea. i mean we would need some one to be able to fab crap up and have a bumper like that to even think about trying it.....and hope the price would be nice and alot lower than 1000.

I imagine the opening needs to be bigger though no?

This intake won't work as well as a modified stock airbox. The opening is in a very poor position. There is just not much air available where the intake opening is.

I guess we will see. Or at least I will see soon enough! I think you said that in the other thread to didn't you? Your the guy that did the cool airbox mod for people right?

I would think that this relies on your having the 99+ intake slot in the bumper to feed air into the area from which it draws. Still though, it seems like quite a space consuming apparatus for a relatively small intake opening.

Hey man! Are you talking about the autoexe intake?

I think it also pulls from the regular opening as well. Take a look at that diagram to see where the air is drawn from. Alot of people have ducting to cover that top part so that air doesnt escape over everything. I think this intake sorta capitalizes on that. If you read the discription of the intake, say one of the features is that it helps redirect more air to the rad and intake as well.

WOW! It is pretty big.. Personally, I'm not sure if you'll gain much thru this unit..

From what I have read this unit will not work with a FMIC, I will be able to confirm this when I order mine in the next couple weeks.

As noted, this is mostly an aesthetic upgrade, the intake is a work of art and I would almost feel bad putting it in a dirty engine bay. Is it better then a m2 intake or another enclosed intake? Maybe, I would think the slight airflow should help, but you arent going to notice a huge difference in performance.

The only other intake that was more expensive then the Autoexe was the GruppeM which was somewhere around $1500 and was discontinued in 2003.

Would this, then, require that you keep the stock IC duct (where the stock intake draws air), or modify any aftermarket duct similarly, and thus draw air away from your intercooler?

haaa. Possibly. It looks like the M2 duct won't work, I'll see soon enough. I think the air it grabs is air that would pass the intercooler and thus not hit it anyway. Im not to sure of this but this is the impression I got.

it was just a thought to give the intake a little more air, even it would be just a little bit.

Very soon indeed Andy :)

I just got the autoexe intake...

Its alot smaller than it looks in the pictures above. Here is a dollar bill along side it for scale.

The intake will be fitted in about 1 - 4 weeks.

thanks for telling me you received it :(

My bad hahaha. I just got in. I took the pic as soon as I got home. Thank you so much for shipping it so quick man!!

i like the looks of the intake...looks really good to me. Also the abflug bumper has a big slot in the top/center that would be real nice for intake duct....even with this intake set-up it would direct air to the area it draws from big time here it is

OK, so did you ever install this? What's the scoop? (pun intended)

autoexe intake
 

i haved this intake and it works well. i am using the stock intercooler. i am thinking of dremiling a small slit opening like the feed bumper has in my stock bumper to supply extra air. it sounds like a vaccum and makes the blow off valve audible.

o wow sorry I didn't update. The project is in hiatus. It will be done but not for a bit.

Some pics of mine to help you get an Idea of the fitment. I can take more of any angle if you need. Just let me know....

Thanks,

how much space is there between the bottom of the intake and the top of the stock intercooler duct?

There's about 1/2 inch of clearance between bottom of intake & top of intercooler duct. It's a direct drop in unit without any modifications to your car.

Yea the measurements I took on the 1st page of this thread are wrong. As goodfellas pointed out to me, the site I took the info from (fd3s.net) got the measurements swapped. I think the width and the height measurements are mixed up.

Intercooler------------------------Thickness---Width-------Height-----------Volume
__________________________________________________ ___________
Stock IC----------------------------2.5-----------11.5-----------4.5-----------129.375
ASP medium-----------------------3.5-----------12.55---------11.55--------507
ASP race---------------------------3.5-----------12.55---------17-------------746.7
Greddy Stock location-----------4.0-----------12.5-----------7.5-----------375
PFS----------------------------------3.5-----------10.4----------10.5-----------382.2
Pettit Cool charge2--------------3.5-----------10.5----------10.0-----------367.5

It looks like I am probably screwed. The smell of fail, it is strong!! We will see for sure soon.

Pics as requested in PM:

The supports are 3/4 inch cylindrical shims + 1/16 washer between the shim and the rad support.

It is all held together by a 1 & 3/4 inch bolt with a washer on top.

Need anymore just let me know....

Thanks man! GREAT SUCCESS!

hey Supernaut, what air intake temperature do you see with this intake? I'm curious.

thx

His isn't installed yet.
