Im about to pull the trigger on getting an Injen cai setup for my hr. I have short rams now, but they feel off and I don't like them. I'm not concerned about water. I'm not taking my Z mudding, plus I'm getting hydro shields for the filter so I think I am set. The only concern I have is a pebble breaking through the filter and getting sucked into the engine. I have searched around and have not seen anybody saying that has happened to them. Has anybody heard or have any experience with this happening?

 

never heard of it

 

Cool. Thanks

 

Don't the filters have a wire mesh? How would a pebble break through?

 

Idk. Do they? I figured if a car in front of you kicks up a pebble, and the pebble happened to hit the filter, it would hit it at the speed that the car kicked it up plus how fast you are going. That pebble would probably be going pretty fast

 

All the cone/cylinder filters I've used had a wire mesh over the filter/holding the shape of the pleats.

I wouldn't worry about it if I were you.

 

Alrighty thanks

 

They feel "off".
What does this mean?
Off compared to what?

 

^That's actually a good point. How do they feel off? What doesn't feel "right" about them? You're not going to feel a huge difference.

 

Maybe just get a tune with the short rams?

 

if you really want to take off the bumper to clean the filters then get them... but get a tune, intakes rarely do anything for you other than sound

 

No way would it make it past the filter or all the way up the piping, don't worry about it OP

If you already have the short rams just keep them

 

They feel off because:

The quality. They don't fit right. They bump up against the strut bar, and the crankcase breather hose is in an awkward spot, so the hose is bent. The clamps come loose over time, and it overall feels cheap.

It's inconsistent. Some days my Z is super responsive and feels great right from the start, but a lot of the time it seems like the power is in the very top end with none in the lower end. It feels sluggish. Another thing that weirds me out about that is sometimes in third gear, I'll gun it, and it almost stutters. It isn't always a constant acceleration in only third gear.

And I think they are holding me back. When I got the tune, I was short on the amount of power I made. Nobody could explain why it didn't make any power. I know it is just a number, but something isn't quite right. It can't really be too much besides the exhaust or intakes, and the intakes are questionable.

I already have a tune from a reputable shop.

When they had it on the dyno, it made an odd resonating sound around 5-6k rpm. It wasn't something clanking around, you could hear it in the engine noise. The best way I could describe it is if you have ever heard two instruments play the same note, and one is flat, it's the "wavy," kind of sound that you get. The tuner had to change a lot of things to get it to make some kind of bare minimum acceptable power, and I think that if I get a more reputable brand of intake I could fix some of these issues.

 

What were the numbers that made you think something is wrong ?

 

^ and what makes you so sure it's the intake?

 

285 on a dynojet

 

There is not much else it could be. The intakes are questionable

 

What were you expecting?

They're tubes with a filter stuck on the end, there isn't much that can go wrong...

 

i hit 286 with my HR on mustang..... its just a number dude

 

I was talking to an older engine builder a couple years ago and he always said track times were far more important than HP numbers.
