hey all

I just finished doing a graveyard shift at work and was on my way home when i noticed a 90's honda accord coupe tail gating me. i was a bit peeveed to say the least so i put the foot down and thought that was the last of that guy........but

we ended up at the lights so it was on (forgive me i dont usually race) lights went green i took off perfectly(i do that about 50 percent of the time so i was cheering LOL) i had him in first and second, i decided togo right up to 6500rpm because of that longggggggggg throw to 3rd but i hit the rev limiter at 7000rpm instead!

as a result i fell right back,(bugger) but it looked like i slowed down for the fast approaching traffic we were doing 80 -100k's by that stage.

i know its bad doing this but it wasnt as bad as it might seem, i assure u when i say i havent had a traffic infringment yet after 6 years of driving so im really careful! (knock on wood)

so back to my question why are there rev limiters?

cheers

its a safe gard for the engine, firstly u dont valve bounce it, starve it and teaches u to change gears more.
anyway save ur street racing for playstation.

Pah, that's how I drive every day. A Rev limitier is there to protect your engine and stop it from detonating under heavy load and blowing a piston or two through the bonnet... internal forces will only go so far before you suffer meltdown. But the 6,000rpm drop off should be enough to reimind you to change gears let alone the rev limiter!!! Holding on longer might keep you acellerating but not quickly enough, you can generally go quicker by changing aroun 6,000rpm or so, depending on the mods u have.

if i change at 6k it then drops under the 5k change over point and loses some power, 7k rev limiter is a goog point for me to change as it then stays above the 5k change point and continues along in the nice powerband

Yes but for those of us without slingshot gear ratios, a VTEC style top end and the need to dance it between a range of 2000rpm, the Zetec engine stays well in it's power band when you change at 6000rpm.
