When I put the car in N, hit the accelerating pad, the max RPM that I can hit is 5000RPM, if I try to go over it, the whole car viberating a lot. Is this normal?

 

Yes, the limiter in neutral / park is limited to 5000rpm.

 

Why are you trying to rev over 5,000 RPM in Neutral?

Looking for a way to throw some hard-earned cash the dealer's way? An unmarked envelope is much more sublte.

 

hi welcome to the forums; bye.

if you just want to throw money away, please send it my way, i still have a bunch of bills to pay.

 

I wish those bills won't cut off your DSL lol.

I just want to know why it limited because I had Honda prelude, Toyota Camery and few other cars, they never have this kind of limitation.

 

It's limited to protect the engine - especially with no load (i.e. nowhere for the power to go); you just end up running the engine fast and hot for no good reason.

;thumbsup:

 

theres also a speed limter. u can't go faster than 150.

 

valve float at high rpm- potential for deadly damage to engine
Other cars are not the TL!!
Make no mistake- everything is special and different than a toy car~

 

Thats not true.

 

Simple... revving an engine that high without a load on it can make it more susceptible to multiple types of damage... first one to come to mind is spun crankshaft bearings.....

Really isnt a need for a redneck tuneup for these cars.... seriously....

 

You can go faster than 150 but the governor cuts the gas acceleration a 153 miles. (At least tats what someone else was saying and I know for fact my Maxima was this way. That I can affirm but not 100% sure about the TL. You can always go faster, if you were going down hill for example

 

Care to elaborate? What about that is not true?

 

150mph will a nice number to reach, but I'm happy with my limitations of 135mph tops...freaken TL-S.

To the OP.... WHY are you racing your engine while in neutral? Just to hear the engine scream?

But then again, I've noticed that here in AZine we treat other cars as our own.... If he wants to abuse his car, let him.... everyone learns from an expensive experience, lol.

 

acura program your car's computer to not allow it to go faster. unless u hack in n change it, which voids your warranty. but if u got no warranty then go 4 it. i heard its suppose to add more hp n saves gas.

 

that means the TL need such computer driving BS to protect itself? Just tried the BMW with my friends today, they are laughing about this stupid 5000 rpm bs. Be honest, I had Honda Prelude back to 1991 to 1998 that car was gave away at 175000 miles and never had any engine problem which I played it much much harder than my today's TL. We are driving the TL for fun, aren't we?


anyway, I really appreciate your guys help! The Acurazine is an awsome place which help me a lot after read your guys posts.

 

it needs it to protect it from idiots like yourself who rev it hard with no load, then come to acura saying, that TL has an issue, I did nothing wrong, fix it for free.

 

What are your BMW friends laughing at? That we tell you that revving without a load isn't good.... or because they dont have a 5k netural rev limiter and they are free to cause any damage to their engine that they please? Seriously do you think Acura puts such a protection measure in place to be a wet blanket? They have to provide a warranty on these cars and if they allow owners to destroy them in such a manner that can be hard to distinguish from abuse or a real defect... they could stand to lose lots of money. Solution.... cut out the potential for blatant owner abuse.

What is the issue with no load and High revs?

It's called ring flutter

The rings surrounding your pistons sealing the gap between them and the walls do not create a seal by themselves. The pressure loads in the combustion chamber themselves seal the gap by pushing on the rings. When you rev with no load (or cruise at 30mph in first gear), there is not enough pressure on the rings to properly seal the combustion chambers. What happens, is the air fuel mixture, and sometimes the crankcase oil is allowed to seep beyond the rings. This is known as blow-by and is bad, for the life of your engine, it's cleanliness, and for kittens everywhere.

Ring flutter occurs when the chambers are not sealed properly, and the rings are being moved up and down by the motion of the piston against the cylinder wall. Repeated fluttering will lead to warped rings and permanent compression loss/blow by.

Lesson to be leared here:

1. There's no need to rev your engine. The only reason people thinks it makes a difference, was back during the days of carbuerated race engines, they would rev them up off the line to get excess fuel that had pooled in the carb out of there, so that when they ran they would have optimal performance. You dont have a carbuerator, you don't have a race engine, you don't have fuel pooling in your ports. No reason to rev

2. High RPM's with no load will destroy an engine, ESPECIALLY during start up.

3. Don't be a ricer, don't rev your engine. There's no need
