Does it really make a difference? I currently have the 4" hoses from the airbox down to the foglights. The only problem is that when I put the foglights in, the engine runs about 10 degrees hotter so I have to either take out the fog lights or route the hoses below the car.

hey lets try to keep the cold air intake\ram air post in the appropiate forums. if ur a TPI guy then post in the TPI forum. TBI post in the TBI forum etc.. or the aftermarket forum. i am not going to close this however. and its not because i don't want these posted in here. its just that u are going to get alot more exposure to people who can help ya out when you post in the more specific forums. and help out the people who are looking for the same things in those particular forums.

and i think you are fine just cutting the stock air boxes out and using your choice of washable filter.

breathment, Why not just move the post to the TPI section? I don't really care as long I get some responses to my question. Isn't that why we are all here, to get the most responses possible? It doesn't bother me if you move it if you think I would get better responses in the TPI section.

will do

i love my 4" cold air........i've heard mixed reactions with cutting the airbox. personally for me i wanted something different.

to each his own.

Is to much air a bad thing?

how bout this box? their still not done..
they are going to be sealed all the way from my foglight opening to the filter...

DannyT

If it's sealed then that is probably the best way that I've seen. My setup functions exactly the same as yours will and I saw very good improvements with track numbers to back it up. You'll never have a ram air setup provide more air than a V8 can handle.

sure too much is a bad thing.........

a good example is those who throw a 58mm when they sould be using a 52mm TB.

there is a such thing as overkill. it's like running to rich or to lean. have to find a balance.

so with these ram air boxes, is that going to produce to much air into my plenum? Having the stock TB and Stock runner and stock intake? My plenum has been ported though...

thanks

every little bit helps, if anything your throttle respons might change a tiny bit; nothing that you'll really notice.

How much of a differnece did you feel Kandie from your setup?

So what kind of differences has anyone seen from Ram air cold air.,,,whatever you wanna call it...



Anyone got any numbers?

DannyT

You WILL benefit from a cold air setup and no it will not flow more air than your motor can handle. I have track results from before and after. The only other change was adding a 170º fan switch.

sure it can.....does a 58mm TB flow more than a 52mm? just as your engine can have to much or to little fuel the same can happen with air. how can you say it doesn't?

my 4" tube worked wonders....there are conflicting stories on wether or not such setups are hitting the "sweet" spot where the air is. works great for me.

I read alot of post where people say they have felt a big differnence from the stock air setup. I have never read anyone say they didnt or barley felt any differnence...why do you say "nothing you'll really notice" so you barley noticed anything? Well then how can you say "worked wonders" "works great" is that what "nothing you'll relly notice" feels like?


DannyT what motor were those results with? Cause I run the same as the results a 15.4 so your saying that I should get into the 14's with a "SEALED" setup?

Kandied91z

working wonders means that it flows the right amount of air....everything i do is tested on a laptop that is directly linked to the obd1 to sense volumetric efficiency. when the stock snorkle was replaced with the 4" "air tube" cai there was a greater increase in airflow hense the improvement.

stand alone you won't feel much more than throttle response and a loud whistle like a supercharger...when coupled with a good exhaust it is noticeable since you can now match the air flow. all mods should be paired up so that you can gain the most from each.

what's the point in increasing air flow into the engine if it can't exit as equally well?

my stock L98 engine with 100,000 miles went a best of 13.8 and pulled a fastest of 104 with this cai, dynomax headers, and 3" exhaust....that's pretty darn good for a worn motor on all purpose h rated street tires don't you think?

i'm just telling you my point of view, try not to be so analytical.

DannyT

That was with a 5.7 TPI/auto in an 89 Iroc with 2.77 rear end

DannyT

A ram air setup WILL NOT provide too much air for the motor to handle.
The debate about the TBs was whether a bigger one was necessary because of other restrictions on the intake side. A TB alone cannot force more air in to the plenum. I know there is a better way to explain this.
A ram air intake will force more air in to the intake such as a supercharger does (obviously less force and less volume).
I have yet to see a cold air setup that does not provide good, proven results.
FWIW I test ALL of my mods at the track and have documented well over 100 runs in a relatively short time.

i have a 1988 305 trans am and was wondering where you guys were taking the cold air from...would through the vents in the hood work?

DannyT

The vents on the hood are not functional. The setups we're referring to redirect the air that flows through the fog light holes in the grill and in to the throttle body.

cr125r

yea, but im talking about making it functional, or would it not be wort it?
