I'm not saying it loses power or doesnt, I dont have any experience with one personally, but from an engr standpoint there are at least two things that could be going on:

1) the longer tube creates more of a restriction in the flow. I don't know how much, but the longer the tube is the worse (as is the case in any pipe flow).

2) if for somereason it lowers your backpressure (and I don't think it would, this would be more of an exhaust issue, but just throwing a possibility out there) then you could lose some torque (but would most likely gain some hp up top.

disclaimer: these are just thoughts off the top of my head based on engr stuff...

Side note: Don't focus so much on peak hp and torque, it's the area under the curve that's important. It's better to increase the power over the entire rpm range than to gain xxxx hp at the peak. You want to get a nice broad, flat torque curve....

 

I'm hearing a number of people say that CAI systems cost you some horsepower. Is this true? Does it help on the torque side?

If it's going to hurt my power, then I'm going to bail on my plan for a CAI.

I also want to get some high-flow cats but keep the stock exhaust....

 

i dun really need the performance....since i dun race that much....but i want the SOUND !!!!

 

I agree with the sound part. I'm not really much of a racer or even a speeder, I just like the feeling of acceleration and the sound of an engine at WOT. So anything to improve that I'm all for!

 

Any intake will not effect back pressure. I have yet to see any real evidence of a CAI causing a loss in power.

If you want sound, get a short ram type of intake, it will sound much better than a CAI because the filter will sit closer to the TB and you can hear more out of it.

 

DONT GET A SHORT RAM!!!! My buddy installed the short ram K&N and it sat really close to the block bringing in hot air. The filter got extremely hot and if we didnt catch it in time then we would have had a huge problem. THe engine was under lots of stress due to the hot air being inducted and the pistons in time will crack if you keep the short ram in long enough.

 

O.o......

well gona add another question
1. Which intakes can be converted to a short ram
2. how many inches are each intake? Stock, AEM, Injen, etc..

 

lengths im not sure of and the only one I know of that can be short ram is the K&N typhoon.

 

First off, he said he didn't really care about performance and sound was what he was after. I'm sure everyone will agree, a short ram will give you the loudest sound.

Why do you say the engine was under "lots of stress" what signs of stress did it show? Cracking pistons due to hot intake temps? I highly doubt the engine bay temps alone are hot enough to cause detonation. If he is getting detonation I would be looking at other things like fuel and timing. A turbo cars intake temps are much greater than that of an NA car with a short ram intake. Proper fuel and timing will help eliminate preignition.

I feel this thread is becoming very misinforming to new users or those who don't know what they want for their cars. Half the people are saying don't get cold air, you will get hydrolock and lose power. And now people are saying don't get a short ram, you're going to blow your motor with it. Both of which are false.

 

Oh, and heres a pic of my Injen w/ bypass.

 

Has anyone thought about the HKS racing suction kit?

 

My friend had the short ram on, the car had trouble idling and the filter was extremely hot. We took it to our buddies shop and after checking it out thats what he told us. I dont get why everybody has such an ego around here and cant just take a piece of info for what its worth. why would u want to buy something that sucks hot air into your engine? Even an idiot knows that sucking hot air into ur engine is BAD so u do the math on that one.

 

It's not about having an ego or not taking a piece of info for what its worth. Its about not misleading people with false information. You basically said if you put a short ram intake on your car, you're going to damage your pistons, or in other words, destroy your motor. Which is completely false.

Yes, I will agree with you on sucking hot air in not being as good as getting colder air in. But that doesn't mean you're going to destroy your motor by getting a short ram intake.

 

Where can I get the bypass valve for injen?
