okay, so i love FCManiac's new CAI. several questions for you experts out there:
1. will CAI make that much of a difference on a turbo? i mean, with any NA car, the cooler air goes straight to the engine, with a turbo there are a lot of intermittant temperature raises and drops where the effects of the cold air could get lost. 2. if i do this, along with a TID mod, do i need a place to dump the air from the stock diverter valve (DV), like with the stock TID or can i just put a cheap autozone small filter on the tip and vent to the surrounding air? i've heard this effects your engine since the AFM has already accounted for the air that is blown off. also, will such a setup be louder? |
The gain should be greater on a boosted car, from what I have heard. Reroute the bov back into the TID(infront of the turbo) as it is setup stock... Stock bov is not loud...even if vented to the atmosphere
|
So you can pull the stock intercooler pipe off that has the hose running to the BOV and vent the BOV to the atmospher then?
|
no otherway around....the IC - BOV pipe/hose needs to stay..... a stock bov vented to the atm. would have it unplugged from the TID and the hole capped up so it goes from IC - BOV - ATM. .... stock is IC - BOV - INTAKE
but stock BOV vented to atm. without EMS will stall or misidle |
that's what i thought, that's what the sport compact magazine said
|
Just remember when venting the bypass valve into the atmosphere you will have a slight problem of being too rich just after the valve closes. This is because you are venting air that has already been measured by the AFM. The ECU still thinks the air is in the system, so it keeps the fuel going. Causing an over rich condition, and sometimes it will kill the engine at low RPM. Uless you are running some type of stand alone, or piggyback like the S-AFC that allows you to tune for a BOV. Pr of course you are running a MAP which would take it's measurements AFTER the BOV.
Other then that, a CAI would help a little with keeping the intake charge temp down further. i.e. lower ambiant air temp, lower combustion temp. But this wouldn't do nearly as much as say.... a better intercooler. |

well, after taking a better look at FCMan's idea, and looking at that fender area, i realize it is WAYYY to close to the ground/flooded streets for me. so, i have another idea https://www.nopistons.com/forums/pub...#>/biggrin.png
so, i've removed my AC system, along with that caniser that sits next to the coolant reservior, and i was thinking if i moved the coolant reservior, and cut a 3" hole next to the radiator, i could put a CAI in front of the radiator. is this a good idea? will i de-stiffen the chassis or mess something up by cutting that hole? i have attached a pic, with a TID mod included. i would move the coolant where the green arrow points, and cut the hole where the green oval is. realize, this is a rough, quick sketch, lol |
I just took a look at the install of the CAI on the other thread. Unless you are fording creeks in your rx, you should have NO worries about sucking in water. I had the same issues with my daily driven neon and the Ice-Man intake I installed years ago. The filter it's self sits a mere 9" from the pavement in the same location as his filter. Through two winters in Cal, then 3 years in Seattle I am happy to say I have NEVER sucked in any water. As long as you retain the inner fender you will have no issues with water. Plus with the brake duct between the filter and pavement, you will have even more protection then my Neon did.
From the looks of this I will be doing this same mod as soon as I return from vacation. |
Anybody with a link to this CAI install procedure? https://www.nopistons.com/forums/pub...R#>/tongue.png

yeah, i like his idea, but cant rationalize the notion of even the slightest possibility of a hydrolocked engine simply due to an ill-placed air filter.
once i get a chance, i'm going to relocated the coolant reservoir and drill a 3" hole next to the radiator. it should work, and i should get a lot more cool, fresh air in front of the radiator as opposed to the fender well. CAI -- shaw style -- will be operational eventually |
Scott89T2 already did something like that, he has a how-to on his website. Check it out here.

yeah, i like that, but i dont really want do rotate the radiator and make new mounts for it. i think i'm just going to punch a hole and hack my way through that metal. it's real thin, so it shouldn't be too bad. then i think i'll just move the coolant reservoir to where the stock air box used to be.
i'm pumped; this is gunna be cool. https://www.nopistons.com/forums/pub...1047683329.gif |
by the way, that whole front end setup is real clean, a little too much aluminum on the shrouds for me, but still it looks great and a real original location for the IC. i like it. not to busy, and it gets the job done.

good idea on the placement Aggie, post pics then and let us know how it turns out.
