Turbo Cold Air... what do you think?

[DSMJim]

Whaaaaattt??

Have you ever looked at your intake temps? Did you read the posts where other people showed the temperature difference?

My intake temps get over 100 degrees all the time, even when ambient is only 60 or 70. A cold air intake would give me ambient intake air. 70 is cooler than 100.

I understand that 100 deg is hotter than 70, thanks. No where have I stated that it's not going to make power. I just am not sure if that 30 deg cooler air before being compressed by the turbo is going to translate into a faster 1/4 mile time on my car. Lets assume the air going into the turbo is colder and colder coming out based on your experience. How much HP did you gain? Doing runs at the track is not really great proof because how fast your run is all depends your launch shifting etc etc.. Too many variables. THe only way I can prove it to myself is to see a repeated gain in performance at the track on my car. I don't know why that is such a problem for you that I just don't take your word for it. Is this insulting to you or what?

I never said it doesn't work, I said only that it's a pretty small mod and small difference so the gain is going to be small so I'm not sure it's going to be worth it or not. Were not debating the effectivness of nitrous or 35psi. Those are obvious huge gains in power. A cold air intake is not a huge gain in power, sorry.

WTF?

A temperature gauge saying that the conditions are colder is not good enough proof? What the hell do you want, an average molecular sped analysis?

I could care a less what your temperature gauge says on your car. That does not translate into faster 1/4 times on my car. Just because YOU say it, does not make it gospel. I prove if things work or not by doing it on my own car. I have found a lot of things didn't work that people say do, and a lot of things do work that other say will not.

So you have to test everything on your car, before you know it works?

Do you run nitrous? Water injection? Propane injection? 35 psi? If you don't run one of those, I guess we can't say it works until you do.

Yes when were talking about something that is debatable if it helps or not (because it may not help my car) were talking about 15-30 deg cooler air only. I may gain 3hp and have absolutly no change in my 1/4 mile time YOU have no idea what is going to happen on my car.

Argueing about Nitrous, water injection, propane, 35psi is stupid. Those are obvious HUGE gains in hp. Were not talking about a huge HP gain here.

I don't know why your getting all upset. It's a cold air intake, really who cares? How much difference could it possibly make? I'm I going to get a 75hp increase? Not likely. Were talking about such a small gain here that it's not even worth debating. Debating small HP gains is for guys with slow cars, not a group of guys who are used to 50hp gains from a single mod and are still not satisified with that.

My next mod right now is finishing up my AEM install hoping to pick up 30-40hp from the stand alone's ability to fine tune my setup. My next mod is going to be pistons and rods in a 1G swap so I can spray 75hp shot ontop of boost. Those are mods that give HP gains. Bothering with a cold air intake is hardly high on my list of things to worry about. Like I said I may mess around with it to see if it helps however I'm not all excited about a 3-5hp gain. Whoptie do.

Lets all relax and chill out on this subject before this gets locked. There is no reason to fight over a stupid cold air intake.

Doing runs at the track is not really great proof because how fast your run is all depends your launch shifting etc etc.. Too many variables.

Same driver same variables before and after the CAI is installed. An increase in trap speed *with no other changes* except the CAI will show the horse power gain as sean has already stated.

THe only way I can prove it to myself is to see a repeated gain in performance at the track on my car.

Your specific car is irrelevant. How did you know what turbo to select if you have not tried it on *your* specific car? How did you know it was capable of the gains you desire?

it's a pretty small mod and small difference so the gain is going to be small

Says who?

I could care a less what your temperature gauge says on your car. That does not translate into faster 1/4 times

A denser air charge caused by lowering charged air temps absolutely translates to faster 1/4 times.

It's a cold air intake, really who cares?

Anyone who wants a fast car.

A cold air intake is not a huge gain in power,

do you have data to support this?

Debating small HP gains is for guys with slow cars

we are not debating small horse power gains, we are debating the effectiveness of lowering inlet temps to ambient levels. Do you consider Vinny ten Lisa Kubo Brent Rau Ara Arslanian George Ioannou or on a smaller lever but equally impressive that dre99gsx pump gas car guy people with slow cars?

dude do you know anything about cars at all? it all the small gains together that add up to the big gain. you ever watch professional drag racing, not the import stuff but fuel dragsters. back in the sixties they were lucky to breakinto the 7's now they are runnin 4.80's. this took 40 years. you know why becuase they kept finding things that would give them a small performance imporvment.

lowering the ambient temps on a turbocharged car has a much greater effect than on a n/a car. ever wonder why u hit fuel cut with less boost on a cold day than on a hot day, thats becuse the air is denser and it takes in lots more.

whoever said that a cooler intake charge dosen't nessesarly mean his car will go faster had better go and get a patent on that thing becase he engineered a motor that dosn't work like any other motor on the face of this planet. with the exception of deisels

basically unless you have an inter cooler that is 100% efficent this is going to help your car. the less efficient it is the more it's gona help.

To all his own.

If you don't think it will work... Try it.

If you have it and it works.... Good for you.

If you like to B*^&% at people's attempts to better their DSM's instead of making a useful contribution to the topic.....
Comon this is out of hand. Lot of great information, but drop the hostility.

shit, if it give me 5-10 whp and it reduces knock by 2 counts or more then its worth 20$ to me.

people who run 7's and 8's do things like cut supports out of their doors to save 10 lbs. do you think 10 lbs is worth more or less then 5whp? or 10whp? who cares. like someone said its a combo of things that make you go faster. now you know jim, just cuz you said what you did your gonna beat by a dsm one day that you think you should have beat and he's gonna have a cold air intake and your always gonna wonder whether the intake was the reason you got beat. no one is making a big deal about it, your hating on something and completely dissregarding the fact that someone said they experienced gains from it. a mod that is cheap and worth 5whp is worth it to me. why do people upgrade to 75mm tb's over stock when they are only making 450-500 whp? i bet they dont gain more then 5-10 whp but they spend over 200$ and they risk hacing a shitty idle without an ISC and they rish breaking shafts and potentialy having a piece of shaft go into their motor ALL FOR 501-0 WHP. cold air is worth it in my opinion

 

[DCsGST]

I recently made a cold air box for my car and will be making a ram scoop utilizing the stock SMIC location soon. By doing this, intake temps while driving will only only be a few degrees above ambient. The proof is in the datalogger.

 

[DSMJim]

Wow im definitely going to do it now, that I have been told. Can't wait to feel the 10hp gain.

10hp gain to me is worth a try but not worth all the BS flying around in this thread. Why the hell is everybody getting so up set? SO ####ing what I said I wanna try it on my own car before I jump on the bandwagon. Just because I want to prove it to myself and not use somebody's else’s car as an example I all the sudden am stupid now and don't know what I'm talking about. Great thanks.

This crap hurts worse then that root canal I just got this morning :thumbdown

 

[Liquid Illusion]

this guy is already making 1400HP i wonder why he chose to go with a silly 10whp CAI :laugh:

So does reading your uneducated assumption based posts. Supported by zero facts and irrelevant conflicting points of view.Also thanks for not addressing any direct questions either.

 

[L2RTSiAWD]

Well I'm glad I got some people upset so that I could read all this good stuff. :laugh:

I have access to the materials so maybe I'll follow someone directions and make one up to see how it affects my car.

I'd say that's more of a velocity stack than a CAI... Try again...

Please tell me you're not serious.

 

[RuBiCaNT5X]

Please tell me you're not serious.

Maybe your definition of CAI differs from mine but here goes...

CAI - Intake cold air from the outside ambient temperature, rather than from the inside of the hot engine bay

Velocity Stack - Air intake at an accelerated speed



Technically speaking, it is a CAI but that is a secondary benefit to having the air forced into the turbo inlet at a greater speed than sucking it through a pipe inside the engine bay...

 

[gsxstac]

velocity stack is when you have the horn looking thing on the outside of the turbo. suppose to make sucking the air in easier. anything where air is being directed towards the turbo itself in my opinion would be a ram air setup. anything that puts the filter in direct flow of outside air is cold air intake. that solara is more of a ram air setup but is basicallly just a better setup of what a cold air is.

Um are we looking at the same pictures?

Please tell me how the ####ing turbo sticking out of the hood in this picture in an ambient location rather than from inside the hot engine bay is not a CAI?

Maybe if you finished READING my post, you would understand what I was talking about...

[Liquid Illusion]

A velocity stack is nothing more then a horn placed over a turbos inlet. A velocity stack has nothing to do with the turbochargers location. Maybe you should go back and read the post where you sarcastically said.

The StreetGlow cars entire turbo location, header design and nose section molding was designed around placing the turbo in an ambient location. Seems like a lot of work for a 10whp gain :laugh: Please at least learn the definitions and terminology's of the topic before you engage in a discussions about topics you obviously don't understand.

 

[16g-95gsx]

Jesus people, lots of bitching here over nothing.

Ive seen huge drops in temps from using my ram air design. Having gone out the other day, with no heat shield blockoff I saw 77-80* on average on the IAT of the 2g MAS, previous logs without this ram air would show closer to 110+. The ambient temperature from that day was just over 72* or so, so the temps were as close to ambient as you could get. One thing to concern yourself with a CAI like this is that the airflow meters die very quickly when subjected to water, forget hydro lock, concern yourself with your airflow meter first. Secondly you are going to dirty your filter incredibly quicker, this might not be that big of a deal but it is still a PITA nonetheless.

Those are some pics of my own personal ram air setup. The ducting has ribs in it which will catch any rain water that might find its way in there, and the air actually must flow vertically, again stopping any rainwater. The air velocity more than adequately forces it up into the engine bay near the filter. You can say all you want but I can definately vouche for the effectiveness of this simple little piece. The cost to me? Virtually nothing, I had the ducting as spare ducting at my house, and even to buy new ducting it costs only a few bucks. Youd have to have short routed pipes to do this, but that just means you're starting to get up there in the modding world anyway right?
