Ever redline your car?
I hit it at almost every time I drive the Ex. I drive it like I stole it. I got really scared one time. I was going about 55 and decided to drop to 3 and pass. About 6000 in three going to four. Got distracted and hit two. The car lurched and the tack needle swung off to the right. I was really quick about jamming the clutch in before it actually caught most of second. After that it started making a loud rattley noise that varied with engine speed. I thought for sure my valves were messed up. I spent that night learning how to adjust valves. Got it all together and the noise prevailed. Turned out to be the alternator pivot bolt. It was rattling against the inner fender. I must not have tightened it enough when I put the underdrive pulley on the alternator.
Moral of the story...redline the crap outta it. Why would they make the gague go to 8000 or whatever it is if that's not what the car was designed for?

I bounce it off of redline almost everytime I can.
As a matter of fact thats how I blew My engine, not because of the redline, but because of a mis-shift at redline in third gear. It was when my tranny was new, and wound really tight, @7000 I pushed in the clutch and the tranny went into neutral, I pulled down and right into second. I knew what i did as soon as it happened but couldnt catch it in time, and watched the tackspin to about 7 o'clock (10,500??) and boom, that was all that it would take.
so 11 valves, a rebuilt head and $3000+ of work, and 30 days later, I got my car back with only 2,999 miles on the odometer.

I did soemthing really close to that, but luckily I relkiazed something was wrong and turned the igintion off, tach past the redline though, I almost went poo poo too.

for example, on my car, if it's cold and my temp gauge is low, i'll hit a rev limiter at 6000rpm.

I really wouldn't know, I drive like a grandma when the car is cold... wait my Grandma drives an Integra Type-R...
okay I drive really slow when cold.

How cold are we talking about....because i haven't seen that low of a rev limiter
i might have taken it to 6 after starting the car....once or twice....

cold as in temp gauge hardly shows any reading at all. once you get halfway to operating temp, vtec should work with the hi cam too.
again, i dont know if it's like that on the civics, but i know most other hondas it is.

All Fuel injected Honda motors, and most other modern motors with a stock ECU have what is called a "safe period" or heat up period when you start the car. It runs the motor super rich to get the cats hot. However this is normally only for 30 seconds, maybe this is what he is taking about. IN theory, if it was running 1.5 time the fuel it normally does, it could be that the higher Vtec operation would require to much fuel to maintian the 1.5 time higher fuel rate.

The whole time I had my car, I probably redlined it twice from n ot looking at the tach. THe car just jolts and lets you go again. One other time was when I was racing I just pedal to the floor and lifted clutch to just screech the tires hella loud. Its not worth it to floor to car to take off.

when the engine is cold, vtec will NOT engage the high cam profile due to lack of oil pressure as the oil is still warming up. (since oil is used to lock the hi cam followers) So, there's a premature rev limiter on a honda that is not up to temp. it prevents you from going beyond your 'vtec' engagement point because of the fact that enough oil pressure cannot be maintained to lock the hi cam followers.

I declare that to be one of the stupidest things I've heard today.

Cold oil = more pressure!

trust me, it's because of the oil pressure and the oil temp that the pre-normal operating vtec rev limiter exists.

Oil pressure is mechanical,maybe the computer can not read it, but its there! ( AND children are only sweet and crunchy after bareque-sp)
