i wonder if your TL rev over 5,000 rpm when its park? i just want to know. cuzz after i put my INJEN CAI in and rev the engine, i notice it won't go over 5,000 rpm. i think that is normal. after i completely installed it, i went for a test drive using sport shifter and it went red line as i ecspected. and i'm assuming the car won't go over 5,000rpm when its parking for some safter reason. i just want to double check with everyone in here.
P.S its sound loud and mean with the CAI installed. for the hp wise im not sure with it gain for that.


thanks

its normal

my too, so probably they are all the same

Yea in Park or Neutral the TLs have a rev limiter (fuel cutoff). I loveee the CAI sound

Its to keep idiots from revving the motor in park- thats really hard on it -
I dont care what they do on the TV car shows- they dont OWN those cars!!!

^^ just curious, how is it really hard on the engine. If you have a link to some article Id appreciate it. I not really too good with the mechanicals of a car so thats why id like to know. Thanks

it is obvious that excessive revs while parked is harmful for your motor

in lamens terms consider the motor while in motion... everything is moving in a nice flow of genious... while parked only certain parts are moving... the parts which are supposed to be moving arent...

The lower rev limit in park and neutral is probably because there is no reason to ever rev it that high. What purpose would it serve? Being that I'm a complete idiot in rental cars, I've discovered that all Enterprise cars I've driven have the limiter at 4K.

High rpms are a little harder on an unloaded motor than one with a load on it. Most rods break on the exhaust stroke. They are weakest with a stretching load on it like exhuast. The compression stroke offers some resistance to the piston wanting to rip the rod apart and the intake and power strokes are compressing the rod. With no load on the motor there's less exhaust pressure on the exhaust stroke. Take it for what it's worth, as I doubt anyone will actually be able to blow their motor if the low limiter was taken off. Think about manuals that let off the gas at high rpms.

it's normal...

Bottom line here,
If we are talking revving while parked, and keeping rpm's within engine design parameters, nothing should be "stretching" until you exceed those parameters.. Not something one really needs to do anyway. A rev limiter/fuel cut-off etc activating at a lower rpm while parked is just an additional safety margin. It's much easier to over rev an engine with no load than with a load.

While driving however, the manufacturer wants you to be able to use the engine within its entire operating parameters. While parked, no real reason to on a factory vehicle etc...

I have never seen any documentation stating an engine will "blow" easier with no load vs under load when operating within parameters. In every case, the root cause for the blown engine was due to exceeding the design, you guessed it, "parameters", nothing else....

I "heard" that you can drop your tranny or mess it up or something of the sort when revving it too much in neutral.

As my dad once said: "wouldn't do it a damn bit of good!!"

do you have a tls? if so, where did you get your injen cai cuz i can't find a cai made by injen for the 07 type s

Neutral drops lol. Yes, not good for the trans. To think in my early years (16-18) I used to floor the gas in neutral with no revlimiter other than the floating valves and then drop it into drive. My dad is still waiting for me to have kids to pay me back for killing the family car over and over. I'm scared to think my TL might one day be driving over lawns, jumping off of loading dock ramps, offroaded, driven into the ocean, etc. scares me.

I hate cars

I agree except that there is less likelyhood of it blowing from excessive rpm when under load. My engine builder who was also an engineer explained that while in the real world you would probably never see the difference, there is slightly more of a chance of blowing it in neutral. I don't think this is why the rev limit is lower in neutral, I think it is for the reasons you stated above.

i got it from my wife's sister husband..he had a s2000 and he decided to bought new air intak. so we custom made the injen intake and put it in my tl it just a few cut and bend that's it..i;ll take the picture and show to u later

thx....looks good
