Short Ram Intake Heatsoak Issue on DC5

[aaronng]

***NOTE*** For you posse's coming in talking about CAI, this thread has NOTHING to do with CAI and wasnt mentioned in the beginning to my thread whatsover (literacy is a must for some of you jackass')

Your first post said:

Theres been plenty of information and misleading information about expensive Cold Air Intakes being superior to a Short Ram Intake on a day-to-day car that would never see the tracks.

So you did mention CAI (unless you truly believe that Cold Air Intake does not mean CAI).

You also said:

Any feedbacks welcome, Thanks guys.

I guess feedback that does not agree with what you believe about SRI is not welcomed.

----------------

My contribution to this thread is my own experience with having an SRI on my daily driven car. With the SRI on, the engine induction sound was amazing but I could not feel any difference with regards to torque (and therefore power). I then created a cold air induction box around the SRI and with that cool air, there was a noticeable torque increase at the mid-rpm range.

Thanks for that correction & contribution aaronng but you know what i mean that this thread is purely SRI intakes, it was mentioned just to let people know but NOTHING to do with CAI.

Theres many people out there with SRI's in their DC5, not only that but any other car, its a cheap, easy and effective mod which most think its better than the stock intake only if you disregard the issue of heatsoak. People like these in this thread have issues with heatsoak in their minds. The more will read this thread, the more ANTI-SRI they'll be.......i bet.

Im here to help and make sure SRI HEATSOAK isnt an issue on a daily driven street car and of course help save alot of money on some poor souls spending over $200 on an intake that would have little gain at a normal speed of 40,60,80,100 km/h.

Theres a couple threads that started already on CAI which you guys can all talk about but im not interested unless i want to talk all-out racing.

^^ Starting a revolution in here again are we now ya hypocrite. Dont tell me you're going to sound like a broken record again and start a completely irrelevant topic with your so called MIATA vs DC5 comparison? ROFL!!! Dont bother wasting your time mate coz you're the only one thats hurting yourself and this page.

Wait, you sounded a bit angry with your "GTFO" remarks...tsk tsk temper temper.

LMAO!!, I was actually expecting another outburst of info from you tonight but whats the matter? cat bit your tongue mate?

In the meantime im just going to sit back have a coffee and wait for chargeR's response

***NOTE*** For you posse's coming in talking about CAI, this thread has NOTHING to do with CAI and wasnt mentioned in the beginning to my thread whatsover (literacy is a must for some of you jackass')

EVLGTR...you are seriously such a joke man. Starting a new thread to use the word FIGJAM amongst other insults a few more times doesn't make anything you say sound even remotely correct. You've already been thrashed hard enough on the other thread no need to repeat that process

You are seriously such an idiot...think before you write.

I'm also going to mention that you ask for explanantions, numbers, evidence and photos and you've been given all of that.

You yourself haven't produced a single thing except for crappy insults

-----------------------------

"and whenyou throw in i/h/e .. and do the proper invetigation," <------oh i thought you were going to write ...add a bit more fully sick aftermarket junk to go a bit faster


How much a stock DC5 atw?.....pfft, i dont even care, it wouldnt be as much as my 32, Aaahahahahah! Jackass

Then GTFO and stop arguing about it if you don't care.
Not one thing you ever say makes sense

*waits for your stupid irrelavant comeback which will contain no actual information, just some new spin of BS and a attempt at a insult*
Prove me wrong..

Talking to you is honestly like repeating yourself all day. Dunno if you can read properly or if its just your selective mind only reading what agrees with you say (which is nothing which makes sense)

Once again all you do is try and pull the most far fetched jokes and insults and that's all you're good for, yet to see you actually provide any counter information whatsoever which is extremely odd seeing as your opinion (or stubborness?) is so strong.

How can you evaluate the usefullness of a SRI without comparing it to other aftermarket intakes? If you compare only to stock it would be deemed the best and then what a crappy discussion that would be.

And no, its not clear that you wanted the thread to be purely SRI especially since as pointed out, ^^^, you even said CAI in the opening post.

[EVLGTR]

your a stubborn keyboard warrior. you stand to what you bellieve in? (that doesnt even make sense, but i understand) Your meant to say, you stand up for what you believe in, and the only reason you do that is becuase you are that stupid and thick in the head, you can't tell right from wrong.

Woke up at the wrong side of the bed this morning? Hahahahahahaha. Go bash the keyboard as much as you like.

[DLO01]

Lets keep the discussion on track lads. Keep the insults out thanks.

[EVLGTR]

@Willow (Lowiez) back to retalin perhaps buddy???.

If you dont like or feel threathened about my insults, its simple mate.....DO NOT REPLY, hahahahaha. Somthing tells me its seems that we share the same brain or something, i say something then you cant help it but reply to it and it goes in an endless cycle.... hahahahaha. Its your call jackass coz this is my thread and im obligated to reply

[EVLGTR]

Thanks Deano.

Ok, guys i wanna see more feedback on SRI issues with HEATSOAK please. You're all welcome (but starting to think Lowiez isnt, but he's still welcome)

[r3ckless]

this guy is a freakin' troll, ban him but plz dont.. provides some humor to my day at the office.

[SpoonS]

He doesn't own a DC5. I don't think he'll ever own one. He refuses to listen to people's comments, and thinks the results of one car has no relevance what so ever to any other car. Its like me saying "i ran over a caltrop in my Jazz today, and my tyre went flat", then him going "LMAO, getting a flat tyre on a caltrop in a Jazz doesn't mean that it's relevant or that it'll happen to a DC5, different car, different results".

Like what nighthawk said, go buy a DC5 and go test it yourself.

Lets keep the discussion on track lads. Keep the insults out thanks.

^ I think you should take that suggestion into consideration pretty carefully OP.

You asked a question, I gave an answer. I can't tell you how much I lost going to 7-eleven (I bought a hotdog a slurpee and a picture mag btw) cos I diddnt write down the details. But rest assured, if my intake temp was higher, (which it would be when using an SRI compared to a CAI, proven! proven! proven!) then my power output would be lower (Due to physics) therefore I lost "some" power. Weather or not you think regard this as a significant issue is for you to decide, but don't ignore or deny the fact that it exists, because it does. Geeeez.

(Now ducking to avoid personal attacks coming my way).

I would say that there wouldn't be any difference in power for the FIRST for 30mins.... the longer you drive the hotter your engine bay gets as we all know therefore putting more heat onto your exposed filter, therefore creating a loss in power.... If your using it for DAILY driving and doing long spirited drives, well then i don't see how it would be a problem but if your tracking your car i'd go a CAI instead... It comes down to personal opinion.. depends which one you want but to be honest.. rather have the filter hidden then be shown.

GruppeM IMHO is just as GOOD as INJEN CAI due to the fact where the air gets sucked from is a current flowing breeze in the direction your driving... Whilst a SRI with the pod in the engine bay, just sits there gaining heat... Fail...
CAI > SRI anyday...

If you want to modify your car IMO, i'd personally get the CAI but then again... some people can't afford to pay as much so your call....

This is the stupidest shit I have ever read. I imagine that every poor soul that reads one of EVLGTRs posts is stupider for having done so.

Some evidence for you, in going from stock intake (which is akin to an SRI as it takes air from a warm source in the engine bay, although arguably in a better location than an average SRI) to a Gruppe M cold air intake I experienced significant intake air temperature reductions in day to day driving situations. Of the order of 10s of degrees. This is measured using a digital gauge plugged into the OBD2 port.

Now if you accept that the ideal gas law roughly applies to air at the temperatures we are discussing, this colder air temperature at the intake equates to a larger mass of air in the cylinder and hence more power. Why would you deliberately wish to intake warm air into your intake? It can be beneficial for fuel economy, but who cares about that.

Dude, you act like a 5 year old, how old are you? Intake doesnt take long to heat up, same time as the engine takes to fully warm really. Stop your car at the milk bar to get your porn or whatever and the intake stays hot under there for your drive home, it SOAKS in the HEAT (If you live Brisbane and North you might be more aware of this also). A CAI doesnt do this.

Do you only drive to the milk bar and nanas house? or are you clutching at straws due to your flawed argument. Most ppl drive further. Personally, I would walk to the local milk bar negating the need for an intake at all!! This thread needs closing too.

My contribution to this thread is my own experience with having an SRI on my daily driven car. With the SRI on, the engine induction sound was amazing but I could not feel any difference with regards to torque (and therefore power). I then created a cold air induction box around the SRI and with that cool air, there was a noticeable torque increase at the mid-rpm range.

The consensus from peoples personal experience definately points to the fact that heatsoak as a noticable effect.

As previously mentioned already numerous times, it is the nature of the proximity of the air intake pod in a SRI being too close to the header which high tempreture exhaust gases pass through constantly and as a result create significant increased tempreture levels in the ambient air that the pod will in turn draw in.
This creates inefficiencies as more air is needed to make the same amount of power compared to if you had a source of cool air, due to the un-disputable concpet that cold air is more dense and contains more oxygen. Oxygen is needed for combustion.
This effect can easily cancel (especially over pro-longed periods as the air heats up further) the benefit of a SRI which is the short piping increasing air flow by significant amounts. This increased flux in airflow through the air intake has the effect of feeding the engine larger amounts of air (but it is warm and contains less oxygen) so as a result you get a pretty loud induction note, compared to a CAI and a stock airbox.

The above concept seems to have been noticed by everyones personal experience on the thread, where no one has noticed any power or torque gain in their own installation and use of one, but have noticed the mentioned loud induction note. Also many of the contributions to the thread agree to the very logically and real concept of heatsoak, which is the reason for the cancellation in the gain associated with the loud induction note, which can create a mental illusion for some users that it is significantly beneficial for performance reasons.

A logically conclusion to the above would be that there are superior designs such as a CAI and those looking for bang for buck should get a injen CAI > branded SRI...seeming as the SRI has very little 'bang for buck' as it has insignificant or no performance gains, which is very often the entire reason for modification in the first place.

Thanks for that correction & contribution aaronng but you know what i mean that this thread is purely SRI intakes, it was mentioned just to let people know but NOTHING to do with CAI.

Theres many people out there with SRI's in their DC5, not only that but any other car, its a cheap, easy and effective mod which most think its better than the stock intake only if you disregard the issue of heatsoak.

Theres a couple threads that started already on CAI which you guys can all talk about but im not interested unless i want to talk all-out racing.

1. Nice edit.
2. Let's not generalize the illusion that SRI's are always cheaper. You're probably seen and refering to (if you have seen any that is) cheap unbranded or 2nd hand / ebay style SRI which are always going to be dirt cheap by the 100's, I bet I could find a cheaper CAI on ebay as well, or cheaper items on any other part of the car. Whether or not they are any good is a different story.

I'm going to compare prices on the Injen CAI which is the most common form of a CAI, and AEM V2 which is the most common form of a SRI on a DC5. The pricing im using is from CRSX as they are generally the cheapest. Not going to take into account shipping as obviously it would be the same for both intakes.

http://www.clubrsx.com/browse/cr/?fM...&universal=yes

You can see yourself

1. Injen Polished Cold Air Intake (02-06 RSX Type-S)
Price: $USD275.00
Free Shipping! *

2. AEM V2 Short Ram Intake
Price: $304.00
Free Shipping! *

Todays rate: 1 AUD = 0.8943 USD
(http://au.finance.yahoo.com/currency...S|b|5479455540)

Makes the AEM V2 SRI $339.68 and the Injen CAI $307 in AUD.

note: the reason why they stock SRI in the first place is because their climate and whether (being where the are in relation to tectonic plates and the equator buts lets not get into that) is alot more unstable. Certain areas are subject to fairly constant whether spikes, floods, ect. CAI isnt great when your car gets flooded every now and then, where the pod is completely submerged

So to say:

Im here to help and make sure SRI HEATSOAK isnt an issue on a daily driven street car and of course help save alot of money on some poor souls spending over $200 on an intake that would have little gain at a normal speed of 40,60,80,100 km/h.

isnt helpful. If you buy a brand new intake for under $200, you might as well put junk in your car or make your own because it will be the ebay special. When considering SRI vs CAI we must consider proper versions of both, going cheap never works especially on a DC5 which aren't too badly tunned from factory. Combination is everything.

Another correction. "that would have little gain at a normal speed of 40,60,80,100 km/h".....you need to get your information right. At lower speeds SRI' heatsoak issue is more of an issue at lower speeds. At higher speeds wind and air rush into the engine bay and help negate the effect a little bit. In fact if you read the study I linked and summarized for you, you would have seen the testing on the lower speeds had higher intake tempretures, which is because of this concept.


So....

People like these in this thread have issues with heatsoak in their minds. The more will read this thread, the more ANTI-SRI they'll be.......i bet.

Good. This concept is called education

So if you're really trying to save 'poor souls' spending money than you should listen and stop suggesting the use of SRI (which aren't always cheaper anyway) on the basis of...nothing? Still haven't seen a personal account from someone here, or a lack of information to back up your statements from yourself. Also if you read peoples personal accounts some have used an SRI, deemed it no performance gain and just noise, and gotten a CAI. This method is obviously more expensive than just getting a CAI in the first place.

I would like to see real information to back up your statements, to be crude everything you said atleast on this page is incorrect information in regards to SRI, as I just outlined to you in this long long post.

If you're reply is going to be something about ritalin or something to do with the amount i've just wrote, don't bother. You asked for something constructive and I gave it to you, like many other times. In return you can do the same, but make sure it's legit and backed with proper sources or whatever. If you CBF to read it all properly, CBF to reply

Conclusion: Because of ^^^^^^^^^^^^^^^^^^^^^^
I still hold that what I said to you originally here is true.

He doesn't own a DC5. I don't think he'll ever own one. He refuses to listen to people's comments, and thinks the results of one car has no relevance what so ever to any other car. Its like me saying "i ran over a caltrop in my Jazz today, and my tyre went flat", then him going "LMAO, getting a flat tyre on a caltrop in a Jazz doesn't mean that it's relevant or that it'll happen to a DC5, different car, different results".

Like what nighthawk said, go buy a DC5 and go test it yourself.

yepp...

[firepower]

I've learnt that you're better off sticking with stock intake + airbox if you want to daily your car. My opinion anyways..
