ok, well i was on the interstate tonight at around 1 a.m. and it was completely empty so i decided to push it a bit. so i'm going abuot 70 and when i floor it i see it jumped to 3rd (driving an auto btw) and im on my way to around 100 while its nearing redlining, then right as it hits the line and shifts i hear this weird sound that freaked me out x_x i thought i dogged my car too hard and something snapped/blew =[ was wondering if anyone, even the MT guys, have had this problem while redlining in 3rd gear? the noise that it made kinda sounded like the intake suction maybe and that's what i was hoping it was but it was a really short noise, like the time it took to shift into the next gear, i thought maybe it was the tranny but i dont think its the tranny because i listened hard to the tranny shifting regularly and no clanking or anything, so i really have no idea what it is and if it's something bad then i dont wanna keep driving around with something seriously wrong.

so i'm just wondering if anyone has any input on this, or any other issue that may arise from redlining too much with the TL ... and i know i might get flamed for speeding and what not... but i mean common, i'm only 18 xP... but seriously, i do love my car and i dont wanna seriously fuck it up... thats why im asking about it...thanks in advance.


p.s. i tried revving really high in neutral to see if it made the noise and for some reason in neutral it revs to like 5k and i can hear vtec engage while just sitting in neutral... was wondering if thats suppose to happen? thought the rev limiter is suppose to cut the revving off before vtec engages. *shrugs* just wondering.

 

Free rev is when your in park or neutral and do wide open throttle the car is programed so that you can't hit red line. Why did they do this.. They did this because in a free rev you more damage on the engine as if you would be driving and decided to go wide open throttle. It takes more time to hit red line while under load and driving. You were at the end of the RPM band. You were in SS mode the noise you heard was probably transmission whine before it shifted.

 

o yea dun wrry keep trying to hit vtec in neutral u moron

 

I doubt there is any problem. If you were in SS mode, you probably hit the rev limiter.

BUT your post makes it sound like you were in Auto, so either transmission whine or that little "buzz" the car (or intake) makes when you cross-over to VTEC.

You should read up on how your car works. In auto, if you apply enough throttle, the car will automatically down shift one or two gears. In Park and N, you cannot rev over 5k RPM and VTEC will NOT engage.





Being 18 is no excuse for being wrong, especially when you already KNOW you're wrong.

 

you need blinker fluid

 

full throttle full rpm can damage the cat! overheat it and melt the guts
then the car goes into Limp mode to let you know- may also throw a master caution light

read the owner manual until you understand it, then go to a High Performance `track day` driving school-
at $200-300 its way less than the ticket for going 100 and reckless driving charge you will incur on the road

Your car on track, with a real race driver as your in car coach, for 20 minute sessions of flat out full throttle- max braking driving..on a 35 foot wide, protected one way road~

 

if u have an intake u coulda blown the mount on the intake... u coulda blown any motor or tranny mount....how does the car shift into reverse n then into drive rough or slowly like before? how does ur steering feel? and dont rev ur engine unless ur rolling or getting ready to launch.

 

yeah, i guess if you read my post and tried not being an a-hole, you would have read that i didn't purposely try to rev to vtec... -_-"... i was trying to tell what exactly was wrong with my car at the higher rpm ranges...

and also, i've revved the engine in park and neutral... park only lets you get to 4500, and neutral actually lets you go to 5000. and it was in neutral that i heard vtec kick while idle revving.

 

hmm now that i think about it, it really didnt sound like a blow, i think it was the intake at the end of the gear. just wondered if anyone else has payed attention enough to hear something like this because i know i'm not the only "moron" that's redlined 3rd in the history of a TL.

but everything else feels normal.

 

hmm the cat makes a bit more sense, but i dont think it was under my car. i heard it directly from the engine bay. but thanks for your tip though. i'm by no means wanting to be a "track car" driver. but if the speed limits 70, then why do auto-manufacturers keep spitting out cars, family sedans even, that can hit 100. =\

 

x_X hmm i was in auto when it made this noise and i'm pretty sure vtec engaged well before i redlined... like i said.. it was redlined when it made the noise... like right when it shifted into the next gear. and i dont suppose its the tranny because it shifts fine when driving regularly. maybe it was the intake trying to suck in last little bit of air before getting cut off to go into the next gear?


and yeah, being 18 is no excuse, but its better than being 30+ and asking the same thing =\

 

So I can go around drivers like you who look for a scapegoat to blame instead of themselves...

Your car is fine.... you hit a rev limiter..fughedaboutit. If it was a problem your car would of told you by now with a nice CEL.

 

Just cause you're only 18 doesnt justify anything.
I'm not saying that what you did was wrong, I'm just saying that's not a valid excuse.
I'm 18 too, but never pull that card.

Your car should be fine, it's an Acura. Not like you are driving a 15 year old Ford.

 

my Celica hit 400-800 past redline between 15-20 times a day, you're gravy!

(it had 120k when I sold it)

 

consider this your first warning

 

you need to read the rules one more time.




guys, this shit is over. Do not post unless you have something productive to add

 

Are you talking about how the car kinda feels like it "pushes back a bit & gives no power" kinda thing? I hit my rev limiter all the time. Nothing to be proud of, just I'm a shitty MT driver...

 

no no nooo, it is definitely not the rev limiter, i know exactly how the rev limiter feels/sounds. this is completely different. like i said i have a feeling its the intake because it makes the exact same sound as if you were going from a cold start and when you rev, you hear that suck of intake. at least i do. thats what it more sounds like... and it by no means has anything to do with the rev limiter... that i'm for sure.

 

yeah, cuz i blamed the guy going around me for an excuse to push it to redline....

but at least your right, i dont see a CEL so i guess i wont worry too much about it now... but then again i just sold a 2002 maxima for having a completely shitted tranny and it didnt give me one CEL about it. =\

 

yeahs, i feel ya. my bad for making us look bad on that.

but just cause it's an Acura doesn't make it invulnerable to my idiotic mistakes =\

 

 

Everyone can gain `street survival driving skills` by attending track days, and the TL is a very capable car when driven with finesse
Awareness of the cars limits and car control will save you from the other idiots on the road--many with no training whatsoever and the rest with no drivers license.
The track is the place to have real fun-
If you cant control the car when a tire blows at 100, dont do the speed

To end the redline issue-
its the rev limiter cutting out the ignition- makes a terrible feel and noise you only make once and go looking for the reason~
Good thing the OP came and asked before trying it again!

 

i attend track days everyday.... i drive in nyc....lmao.

 

When i go all the way to redline in my dads GMC Envoy, its auto, u can hear a suction sound too. But nothings wrong. IT just the amount of air witch is alot when going over 70, and WOT.

 

He meant track events, not demolition derbys.

 

DO you have CAI? My car makes a short sucking air sound when i shift right b4 Vtec or at around 4k rpms+ in any gear. I think it does it too when i redline it but my car is too loud to tell. When your car shifts it stops accelerating and goes wide open throttle right after it shifts to the next gear sucking in a lot of air. Maybe thats what your hearing?

 

yeah, for the guy who bought it!
The little Yamaha was meant to be driven hard, a good number of people on the board did also, and there were many discussions about max rpms - 8600 was deemed to be the "weakest point something could break" (which was the oil pump gear I believe)
I don't see discussions like that over here though (maybe I don't go in the right child forum?)

 

+18

 

yea if the mount on the intake broke it will make extra noise. check the bracket carefully.

 

^ When my mount broke... I sounded like a 1994 civic..with steering wheel vibrating...

 

nahs, i think its what juruki said, all the other gears sound fine, even when redlining, or high rpms, its just 3rd gear for some reason which is usually past 70 when i'm at WOT.

plus i have stock intake so i dont believe the mount broke. is that really possible on a stock intake?

 

Like i said, i always hear that suction sound, on my dads 03 GMC(WOT). But only heard it 2 on my TL(WOT).

 

The ECU is programmed to keep the car from reving past 5K in neutral and in park to keep motor damage from occuring. Valve float and other things might occur under non-load situations and cause damage.

You are right on the damage portion, that more can be caused in non-load than under load situations. However, there should be no whine while shifting with the AT's!

This could be a possiblity since the mounts on the AEM intakes are breaking off frequently these days.

I think I might know what the noise was, either the rev-limiter bang or backfire. Do this:
Put the car into SS mode after it has warmed up to operating temp. Drive on the highway and shift down to the lowest gear you can. Then raise the RPM to redline and DO NOT SHIFT. Keep on pressing the gas and suddenly the car will start bucking slightly and the RPM needle will bounce. This is the rev limiter under load, which sounds different than under non-load.

Or

was the sound like a loud bang? It could have been backfire since the car was dumping fuel at WOT for about 30 MPH.

 

sorry, but again i know exactly what the rev limiter does and soudns like. and this noise i'm hearing sounds nothing like it.

it doesnt make the noise while i'm redlining but during the shift into 4th if that makes sense. like i said i still think its an intake problem because it sounds much more of something along that line. which brings me back to the question, can the stock intakes break like the aem? i have a stockkk intake not an aem.

idk it only seems to make the noise redlining 3rd gear, auto or ss, but only if you redline it. all the other gears sound fine redlined/normal driving. so i dont think ill worry bout it too much, i guess the solve to this is to not redline 3rd anymore xP
