For my fellow member. for those of us who have had to become very create and wander the aisles of the hardware stores looking for something to fabricate a CAI
system. Whether it be on a carb'd or Fi like my se. Go to www.spectreperformance.com. They have just released a bunch of products that allow us to do just about anything for our intake systems. From running dual cone filters on the se to multiple ones on a carb'd. They seem to supply all we will need to make the coolest set ups yet with the least amount of effort. I personally think i am going to make a 4way intake system for my se. rx7doctor

 

This Thread Is Useless Without Pics :d

 

I went to the website and saw many pics !

Thanks, Doc

 

It's his standard post with me. It's because i can't figure out how to attach a picture to any of my threads to save my life,lol. And your welcome Grimes. Lets see who can come up with the wildest setup. rx7doctor

 

booooooooo!!! nothing for us weber guys...

 

How about a wheaties box to make it go faster,lol.
You can still make something work. Thing of making a rectangular to round adapter to go to carb where the air cleaner attaches. Then you could use any of the piping to do the rest. Yes, you can do it. Then post it and have all the weber guys bowing at your feet. rx7doctor

 

^ if only i had the money!! and what if i orderd the wrong piping? it should come in some sort of a set.. i was thinkin of using a turbo hat type deal. then running my own piping

 

tip for you and all others. According to Spectre. Autozone has become the authorized supplier of these products. As i was last told they are using apporx 500
stores as test sights at the moment. All of the Auto zones are supposed to be stocking all these parts soon.
As far as the turbo hat, great idea. rx7doctor

 

Auto zone is stocking the piping? hmmm, have to check it out tomorrow, i havent been in that store for a year, im more of a napa or orileys guy

 

looks like modular plumbing piping with 'chrome finish' coating. Why not just buy the same piping in black from any hardware store and save yourself shipping charges?

 

Yes, your Napa and O'rileys are much better for quaility parts. But companies like spectre make deals with the "Big Advertised Names". Remember i said they are supposed to be stocking the piping. May not be in your area yet. but if you go check it out and let us know what you saw if they had the stuff in stock. Thanks, rx7doctor

 

you guys....go to Advance Auto Parts, legendary customer service. But, we don't have these pipes and stuff, I would suggest Ace Hardware.

 

we?

 

He's stating that he works for advance auto.
PLumbing/hardware store. Whats up with you guys? I went thru all the big stores like orchard/osh, home depot, etc. Could not find jack squat for fabrication. Initally i bought some obsoleted mr gasket kits for Hondas and chopped them up.
The smoother the interior finish and adapability of angles the better the air flow will be.. Be a professional and fabricate with pride. What do you think we are fabricating? Incar plumbing for a toilet,lol.
As far as i heard the pricing is supposed to be resonable. rx7doctor

 

yeah, i would go get some pvc pipe, but i want my car to not only look good when u open the hood, but i want it to perfom well also, so i guess im going to check it out tomorrow when i get off of work, or maybe ill just check thier website. ive never been so inspired. but those damn carb turbo hats are expensive

 

if you want a single tube and dont mind paying extra.

mock it up in PVC, then send it to stainlesswork. They can duplicate it in Polished Stainless steel.

$20 a bend, and around $10/ft of pipe.

^werd! might just do that bro, but um what do u suggest about the "hat" to go around the weber throats?

 

you know what I would really enjoy, if someone posted the part numbers from that site that can go together to make a functional CAI for the first gen. Piping that goes to where the headlight washer fluid resivoir is on the Canadian cars, thats the front passenger side under the headlight im talking about. I would certainally get one, I just get confused as to which parts I should purchase...

 

Fundamental question- has anyone ever proved a 'cold' air intake actually improves performance on a RX-7?

I did lengthy research some years ago on a Lotus engine with Webber carburation and found no measurable change in temperature when the car was moving. We use very accurate electronic measuring gauges from a laboratory. The air in the engine bay was replaced so rapidly that even directly behind the radiator there was less than a one degree difference between internal and external air. With the car halted there was a slight difference. If the fan failed there was a difference due to lack of air flow.

A significant impact on performance [ up to 4%]was the design of the air cleaner, even better when it was absent. But the major intake factor was the length of the intake tube after the carb. The extreme case was a mini where the optimal intake was so long we moved the central instrument panel in the dash to accomodate it.

This is the same on the RX where the best Webber DCOE set up is with the wrap round intake.

So other than a more complex engine bay, is it worth it?

 

yes i think it would be, for diversity. and looks. but i would route mine to the drivers side in front of teh radiator, better than all those bends to go to the passenger side, plus you could move your battery and have it sit there, cut a hole out where the radiator mounts and fab up some diffuser plates to force air into the intake..

 

^^^ im confused by your post, what do you mean by all those bends to get to the passenger side? It would be a straight pipe with a 90 degree bend in it at the end in order to go where that resivoir is. The location im talking about is the same location they used on the maz speed "ghetto looking" CAI. With using a hole saw just cutting the headlight resi filler cap hole bigger...

I don't really know how effective the setup would be... Personally I think im just going to go with a hole aftermarket intake setup, this mod would be good for a stock car looking for a couple really minor mods. At this point im looking for good horsepower upgrades for my car so I do not think it is applicable for me.

 

well i have a DCOE wish is a side draft, so the air horns point horizontally towards the oil fill tube, so i would HAVE to route the piping ot the drivers side to limit the bends. get me now?

 

yes, haha I see what your saying, I think that would just be foolish to do though, the setup the way it is sucks in alot cooler air then the stock setup considering the location of the exhaust. If I was you I would just keep it the same.

 

does no body weld anymore? do any kind of metal fabrication? it's easy, get some sheet metal and make a tube..bending the pipe can be tough...you can use a number of things, roll up a piece of tire and stick in it, then find something round, and bend the pipe around it slowly..the tire will hold the shape (or roundness) without crushing the pipe..
