Well I know about how an intake can cause problems without a tune. I would like to get one but since I don't plan on getting a tune for a while will I actualy LOSE performance or just not see much of a gain. I was looking at the hks rs kit or injen kit but if other intakes are known to work better post em up. Does anyone have any actual dyno numbers proving that you will lose power with just an intake and pipe?

 

Both of those units cost a lot of money, and the most you get out of them is sound. They DO make power with a tune, but most of that is from the tune, not the intake. There are countless examples of where an untuned aftermarket intake like the ones you mentioned has caused erratic idling, lean spots, and poor MAF readings. Often, people will dyno and see a higher peak HP, but the power curve is all jacked up from the MAF being thrown out of whack.

You could save money, still get a few hp, have a car that runs perfectly (with OR without a tune), suck in ONLY cold air, and make up to 400-450whp unrestricted by staying with the stock intake and adding a drop-in filter (works or K&N). You could save the most money by just keeping the stock intake and stock filter...there's nothing wrong with it.

 

Avaien --- This is a huge debate... Because just as Warrtalon mentions there are many folks that say that they got not performance out of an intake and then there are just as many that tell a completely different story and say they received nice gains even with out a tune....

I currently have the K&N drop-in filter and I have been a little happy with it but not completely... I drove a friends EVO with the Burchur Racing intake and there felt
some difference (his car was untuned) ... More pull and more responds....

Go for the intake..........

 

Everyone keeps saying you need a tune for an intake but what is there to tune other than AFR?

I added the BR filter to the stock intake pipe and noticed no power loss or gain. I also didn't have any side effects like hosed up MAF readings or poor idle. The one thing I did notice is my mileage dropped. This is primarily from forcing the car to spool at every opportunity.

The intake trumpets the spool and amplifies the DV big time. Sounds like a 747 and a F&F BOV. Other than those few things I noticed no difference at all.

 

This coming from a guy who doesn't know how to install a boost gauge
The little gain in power you probably felt was from the car running leaner than stock and the timing not being pull back most likely due to cooler conditions. On hotter days the stock intake car would probably be faster than a car with an intake and no tune because of timing getting pulled back.

Listen to Warrtalon, he is correct ... there is nothing to debate here ...

 

DaWorstPlaya -- Yikes... Personal attack.... "Boost Gauge...." You are sooo funny....

Just because I was asking questions about a boost gauge install does mean I can't comment on an intake... If you read my post you would notice that I simply mentioned that there have been debates on this. (And there have been a number of debates on this forum and others)

I also told him to "Go for the Intake"... Why not? It is his money and if he wants to see if there are improvements why listen to a hick from Nebraska, or a guy like me... Best way to find out if an intake is for you is install it and then if you don't like it bring it back to stock...

 

Sounds like a great way to waste money to me. I would definitely not recommend this course of action to anyone. My whole purpose is to help people SAVE money...that's why you ask questions before making unnecessary purchases.

 

Use the money you were going to spend on the intake to get a reflash if dont have one.

 

"Warrtalon " does not know jack he is smack talker he acts like he knows what he is talking about but if you read his old threads he is blind to the evos performance building.

The intake is a good investment for two reasons

1.spools up about .500 rpms faster
2.throttle response is twice as good as a stocker
3. and sounds good (extra bonus)

IF YOU ARE WORRIED ABOUT HEAT BUILD A HEAT SHIELD VERY EASY I AM CURRENTLY PERFECTING A DESIGN I WILL SELL, THE HEAT IS NOT A BIG DEAL THAT IS WHAT A INTERCOOLED ENGINE IS FOR,

 

Evil Evo 8 -- Thanks for the support. I knew that there were others on this forum that have supported getting an intake...

 

the best intake setup is either: 1)the stock airbox with a drop in, OR 2)the HKS Kansai CF airbox with a cone filter inside it. you will need a tune to benefit the most, but most people will "feel" a difference driving it untuned. keep in mind that the above intake style is only appicable to people running the stock ecu/stock turbo and have less than 400whp. after that, the box becomes a hindrance.

 

Nice stereotyping buddy .... tsk tsk sinking that low
Why should he waste his money on a intake that makes more problems than it is worth, when he can get greater preformance doing some other mod?
Warrtalon has provided factual data to support his/our point why don't you guys provide some factual points to support intakes?

My biggest problem is the tubing diameter of intakes messing up the MAF readings to the stock ECU. As long as you can get the same diameter tubing as stock on the intake your MAF reading should be correct, but can you tell me which aftermarket intake has that? I didn't think so ...

I was just kidding about the boost gauge install ... btw do need info on how to do that from a hick like me?

 

Alright... I dropped the gloves because you seem like a nice guy but the boost gauge comment was also a low blow.... Any how.... I will be looking for some links regarding the advantages of the aftermarket intake.

 

do a search on this subject, Shiv of Vishnu Tuning has said time and time again that a stock intake causes more problems than it does good. you may pick up a couple peak hp but the turbulence in the airflow caused by the intake is hard to tune around. All of vishnu's stock turbo cars have stock intakes. he was in road and track and so was his car. nuff said

 

I'm not telling people to go out an get an intake but I'm not trying to say you'll have tuning issues and lose power either. I had no problems with the BR filter on the stock MAF with stock intake pipe. If you go with an aftermarket intake pipe....there are other things that could cause issues.....like the fact that the PCV feeds into the stock intake pipe but would probably be vented with an aftermarket pipe. Also the stock BCV is tapped into the stock pipe and I haven't seen an aftermarket one have a nipple for it.

Lets be realistic here....once the car is moving there is plenty of cool air in the engine bay. When the car is stopped both stock and aftermarket are sucking in hot air.

Answer this.....Other than the fact that the car is getting air faster (helping spool) and possibly a leaner (but not dangerously lean) AFR what needs to be tuned? Everyone keeps talking about crazy MAF readings but I didn't see any of that.

The only legit complaint I have heard was getting more air than stock and therefore on cooler nights they sometimes hit MAF cut.
