Intakes
 
ANy thoughts on intakes for the PRO5?! I get different answers from anyone i talk to. The shops all say don't buy anything except the full lenght cold air. But on this site and others guys seem to just buy the cheaper short ram air intakes. Prices is obviously a factor in this decision, 300 and up for cold air and 120 or so for short ram air.

Especially here in Calgary where is doesn't get all that warm for so long and where the humidity is pretty non existant!!

Please some thoughts, and prices around town if you have suggestions [AEM, Injen, Ractive(cheap cost.)] Thanks

did you look around the forum????


Intakes have been covered a million times, so instead of me giving you a single reply, just click on the upper right hand corner, where it says 'Search' and you'll get tons of replies that way ;)

Welcome to the board :D

Broich, Welcome to our happy little corner of the net, and to our Club. There are TWO BIG fridge'S in the corner with anything you can think of in them...help yourself...of course only take what you can LEGALLY have.

make yourself at home on one of the big fluffy couches, kick your shoes off, put your feet up on one of the tables, yes we are allowed to do that, mom don't care....and take it easy.

oh...btw....every once in a while a food fight breaks out...so you may not want to wear nice clothes here.

Welcome!!

Intakes.....yep that is a well discussed topic....and here is what it pretty much boils down to...

BUY what YOU like.....What YOU think looks good....what YOU want. As I believe you would be hard pressed to find any hard evidence that any one intake is any better than the other as for how much it adds h.p. wise.

Personally....I like the INJEN....if for no other reason than it looks the best, in my opinion.....

here is what mine looks like in my P-5

hey sup i live in calgary.. i got the InJen, check my www for pics it costs $425 CAD for the intake (i installed myself) from Autozeal on 16th Ave by the BRICK

16th Ave / Center St. (close to here)

i got an aem short ram intake from groupbuycenter.com for 145.00 usd shipped overnight for free...i think the place where i bought it was no limit motorsport from new york...

Broich November-4th-2002 10:46 PM

Hey guys. Thanks for the replys but.... no one has any experience with the hp issue or the cost vs. quality and usefullness issue?! I find the $120 Ractive price obviously better than the $320 cost of the AEM cai or Injen cai. But what is better. Like i think i said before, the guys at the shops (MOPAC and RPM) both claim the short ram( ractive style) and not even worth it. But do they only want the sales?

And the weather/heat/humidity must have a factor in all this as well.
Should i also buy a K&N filter to go with any of these systems or they come with sufficient filters?! Please i want to buy soon. I first buy the b&M short shifter kit, the novelty is wearing off and i need some thing else now.......

mesoh November-4th-2002 10:48 PM

hey, me from calgary....got ractive for 130 sumthing at speedville, but shop around. call around till you find cheapest one then call around again and try to get others to beat that price. thats what i did

Well, a lot of people have experience with both HP AND cost vs quality.. U just have to do a SEARCH to find them.. For months this board was nothing but "Intake Chat" (to quote another pclubber) so there's plenty of information to be found if you look.

In MY experience with having the ractive shorty (even shorter since i cut the pipe) for a bunch of months now, I've noticed:
- a decrease in my wallet of about 120 from the purchase
- an increase in sound
- a decrease in mileage (probably due to driving it harder just to hear the intake)
- and no change in HP

I think you'll find that going with a full length CAI, you'll experience the same results, but with an even bigger decrease in your wallet.

As nuke said... Just like having a wing on your car, the performance difference is negligable if at all, maybe even taking away from it, so go with the one you like. It's all about the looks after all!! :)

I got the Racrive:


Once I installed it I noticed that when I was doing 100km\h my RPM was only at 2800, vs. stock, where the RPM would be about 3000 or more.

I also did some experiments with the filter itself by restricting filter area, and I noticed that power went down, so it seems like the biger the cone filter the better.


As to the pipe I didn't have the resources to try something smaller than the 3" pipe. Maybe someone else here tryed that...


Lastly, it runs way beter at speeds over 60km\h. I have a custom air skoop under the car that goes right into the filter through a 4" pipe. Kind of like a jet fighter skoop.

Heres a question (I searched and couldn't find ANYTHING). You you install a short ram or a CAI, up here in canada. How much longer does it take the car to warm up?

In winter it gets cold and I would think that if the car is constally pulling cold air in it would take a LOT longer for hear to come out through the vents to warm ME up.

Any comments from those who have em?

I bought the Ractive and had to modify it as most others here have done. There's some awesome descriptions on how to do it on this site. Do a search on Ractive and see what turns up.

As far as comparos I think SirNuke summed it up. Do what you like cause in reality the intake is not going to boost your car to super status. I thought mine would but it didn't.


- a decrease in mileage (probably due to driving it harder just to hear the intake)
LOL that's me. Got even worse with the short shifter!

Anyway buy what you can afford and let the butt dyno be the judge. As far as i can tell the noise is the best part :)

good luck and welcome to the board!

The temperature of the air has no real bearing on how fast the car warms up. Your engine has a cooling system that is controlled by a thermostat - when it's cold, the thermostat closes and allows less coolant to pass through the engine, thus warming it up faster. When the coolant's above a normal temp, the t-stat opens up to allow coolant to pass through faster, thus cooling the engine down. That's how your engine is able to stay cool on those perfect days where the needle spends more time around 5000 than 2000... Outside air really has nothing to do with cooling/warming your engine.

To keep you warm - outside air is drawn into the cabin through vents just below your windshield (NOT your intake!). It's passed over an object called the heater core, which gets its heat from the boiling hot coolant passing through your system. The air is heated as it passes over the core, which is then blown into the cabin, keeping you warm.

Kinda funny to look back now, but for years I thought that the air blown into the cabin was coming in through the air filter. Was shocked to find out that wasn't the case! :)

That, and the fact that the air is going from outside temp, to a few hundred degrees in a split second (in your engine) - whether the air is +20 or -20 isn't going to make the flame any less hotter or colder.. (that you're going to notice)

So, to make a long story short, I have the ractive and by the time i let my engine warm up for a few minutes and drive for a few minutes more, the car's warm.

Tornado November-6th-2002 10:47 AM



Wow! I thought the same thing about incoming air from the intake, until you just educated me. That's pretty cool, and a brain twister on how the air heats up that fast.

:dunno:

Thanks for the interesting info :D

but the entire point of cold air going through the pipe is the temp sensor sees cold air and advances the timing and puts more fuel in, thats how you get more power.

broke down
 
Well i broke down and finally bought one. I purchase a Ractive for 110 canadian at my dealership. Sounds cool, but as for any real change..... Who could actually notice 1 to 3 hp?! And you guys are right, the bracket is useless and i've got all the same noise and knocking problems. Any one have a strange vibration noise (possibly just loose exhaust somewhere) at certain rpms? As well as the hose clamps were pretty shitty, did anyone else have to go buy better one? I for one expect better from a kit for any price from any manufacturer , i don't think for spending less the product should be inferior..

Thanks for the info for the decision making situation.
