I have put my car in neutral at 80 with a pop charger just to test this and it went to idle and never shut off, some people have this problem, some don't I guess.

and are you going from 2 to 1st at highway speeds? do you mean at say, 80mph, you put the car in neutral and slam on the brakes till you are slow enough to get into 2nd or 1st and that is when it stalls?

you should leave the car in gear when slowing down, even downshifting is good, relying solely on the brakes is not safe. especially when hard braking. try that and you should have no problem.

 

Show me hard facts such as dynos and flow charts that prove a aftermarket intake system will yield more than 5whp over stock airbox with a modified filter. If it doesn't make more than 5whp then its worthless to spend $100 or more on it.

Notice I said stock "airbox" not stock intake. I agree the stock filter sucks, but the stock airbox is great because plastic is the best heat resistant material.

 

Just raise your idle a few hundred rpm's you should be okay.

 

the stock airbox is good (on the 06 is better but loses tq) the intake tube should be replaced and the filter element, but it really is more about sound then performance for these shortrams. they sound really nice

 

me? my idle is fine, I stated I never had a stalling problem. but I was thinking of doing this anyway, cause after the TB porting, my idle is slightly lower then where it was before. thanks

 

I used to have a K&N air charger system and I actually lost power with it. So I put my stock 06 airbox back and gained my power and torque back.

The 06' airbox doesn't lose torque, it actually makes more power than the 03-05 because of the velocity stack. I will agree with you on the sound part, the aftermarket filters and system are louder and sound meaner.

 

Pop charger has a great filter design, I think it is a little less restrictive than factory airbox.

 

The pop charger just has a metallic heat shield, and we all know the whole point of the intake is to prevent heat soak. The stock airbox does this with ease, no heat= no loss in power.

I'm not saying the POP charger is bad. I'm just saying the 06' airbox has a great design and with a aftermarket filter there isn't much of a hp difference compared to a POP charger or any other aftermarket intake.

 

I guess you've never heard the saying "in a spin two feet in."

 

if the car's brakes fail you are supposed use gears to slow.

 

actually, they tested the heat with a gun and fount the temps higher in the stock airbox.

and from what I saw readin through builds of japanese tuners, they use the intake systems to gain low end-mid range, and the stock with the velocity stakc to push the gains higher. <but that is from what i have read. no first hand knowledge

 

Thanks for solving my stalling mystery guys. it happened twice at the racetrack (coasting under a yellow flag for a few seconds before engaging a lower gear). At least I know it's nothing serious. I like the Pop Charger for the wicked sound it makes above 4000 rpm, esp. in conjunction with my Kinetix V+ intake. For a couple horsepower, there is no real tangible performance gain.

 

I agree . Not much diff about the pop and the stock but why does the ECU not adjust well, there has to be a difference in air flow to cause the Pop to make the car die that is all I am saying.There is a difference in aiir flow might not be much but there is enough to throw the ECU off. Now with that said I dont go 100mph and put in nuetral...I am not the sharpest knife in the drawer but I do know that is not good with stock or aftermarket intake.

 

Anytime you interfere with a MAF sensor, you will have problems. Is it really worth 5whp and weird idle? Stock airbox does fine, with a upgraded filter. We'll always have the same arguements, CAI vs Short ram, POP vs OEM box. I've had both aftermarket and stock box and I feel stock box is better for me. To each his own, i'm not here to convince anybody to change what they already have.

But a lot of the japanese tuners do use the stock airbox, and the one used on the nismo S2 package is a stock airbox but a bigger velocity stack and bigger MAF housing I think.

 

I thought it had something to do with the popcharger funneling more air over the mAf sensor when it thinks it should be seeing much less, since the stock airbox doesn't pull air after the throttle plate is closed. it was a looong time ago we had these discussions.

 

Was it on a stationairy vehicle or while it was moving? Comparing intakes is very difficult because you don't factor in air pressure @ certain speeds.

 

honestly, as I said above, these issues about the pop charger were beaten to death a while ago, so my details are fuzzy. I beleive it was tested after dyno runs, but I could be wrong.

honestly, the reason the pop charger is the preferred short ram is the velocity stack which give it the whistle and performacne gain over others.

I have been meaning to pick up a 06 stock box my freind has to fit it.

 

The 06' airbox has a nice big velocity stack also. You should check them out, quite a bit of difference from the 03-05 airbox.

 

I tried to induce a stall with my popcharger during my roadtrip last weekend.
80+mph put into neutral = did not stall

edit: i also recently got an infrared thermometer. after a drive, the inner-part of the heat shield was around 20 degrees cooler than the outside part

 

I wish I had the stock air box , my VT cf hood has many air vents getting my Pop wet
Rain stinks
