I have a stock DX and I just put in an EX cluster with the tach. Before I shifted way conservatively. Like at 2000 RPMS. Now that I know whats going on with the engine, I like taking it higher.

My question is that is it safe to take it to redline? I mean I know that it's built to go there right? But the car screams at 4000 and i'm kinda scared taking it past that.

Also when I shut the car down it makes a pinging noise. I forgot what the proper term is, but how can I minimize it? Does that mean I'm too hard on the engine?

 

the pinging is just metal and aluminum(sp) cooling down, all cars do it new or old....

i have 16X,XXX miles on mine and i take it to red line every now and then....

 

redline it about to 6500ish

my friend does it all the time and he has 250,000 miles

 

i have 159,000 miles and I hit redline at least 5 times a day...if not more. Just keep your oil changed...you'll be fine...your honda engine is designed to operate anywhere outside of the redzone...

 

should you redline in only a few gears, or can all 5 gears be redlined?

 

its okay to redline all gears but it would be kinda hard to redline 5th and endanger your life.

Try it i have done it in four of my five just had to slow down cause i was nearing the end of the strait

 

lol. I don't intend to, I was just curious.

 

you're in a dx and have a 7 and a quarter redline. dont bring it to the cluster's redline. i believe a dx redline is 6500.

 

i just wanna take it to 6k that's enough for me

whoever told you that is an idiot. Pinging is when two flame fronts crash against each other. Its a uncontrolled ignition of the gases in the combustion chamber.

 

yup. that's what my autoshop teacher told us. The question is that is it bad? I think it is, but how bad? When I abuse the car it is louder and more rapid.

lol..agreed.

 

I have a DX and was wondering approximately what the redline is in terms of mph. I know that it will vary depending on the road, but what is the mph at redline on flat roads in 2nd gear?

I have always been curious and am too cheap to get a tach.

Dude chill out, and read a little slower. He said "Also when I shut the car down it makes a pinging noise. I forgot what the proper term is, but how can I minimize it? Does that mean I'm too hard on the engine?

To answer the question, It doesnt mean its hard on the engine. Its the normal sound of the aluminum and other metals cooling down as the one dude said. One reason it could be louder is because running an engine harder produces more heat.

 

I wouldn't "shoot" for redline in first gear becuase it comes so fast. Try and shift about a thousand rpm sooner in first, once you react to it your just about there anyways.

Please remember that if you take your car to high speeds make sure your tires can handle it...

 

My opinion, is that often times honda designs its heads well enough that its safe even a bit past redline (till fuel cutoff), Its not going to hurt it terrible, but I always try to not to mash the throttle, or keep at high rev's unless I need to.

Be conservative with your rev's, and I'm sure that it will increase the life of the engine, even if the engine will last for a long time ******* it.

That's unless you have a swap in mind, I know some freinds who were trying to kill their cx motors so they could put in swaps, but that motor just wouldn't go!

 

haha i'm killin mine right now.....got taht b18b comin soon as it can....

 

The pinging is ok. You can bring it up to 6700 or 6800 and not have any problems. My 99 Dx hatch took a beating for 50,000 miles without any problems.
